The concentrations of five cephalosporins and amoxicillin in breast milk were studied in 42 voluntarily participating lactating mothers using standard assay methods. Each mother received one single dose of 1 g of either an orally or intravenously administered antibiotic. Amoxicillin, cephalexin, and cefadroxil were given orally, and peak milk concentrations averaged 0.81 +/- 0.33 microgram/ml at 5 hours, 0.50 +/- 0.23 microgram/ml at 4 hours, and 1.64 +/- 0.73 microgram/ml at 6 hours, respectively. Cephalothin, cephapirin and cefotaxime were given as an i.v. bolus injection, and peak milk concentrations at 2 hours averaged 0.47 +/- 0.14 microgram/ml, 0.43 +/- 0.16 microgram/ml and 0.32 +/- 0.09 microgram/ml, respectively. The high concentrations of cefadroxil can be explained by its low rate of elimination and higher fat solubility. Milk/serum ratios for all antibiotics were increasing as serum concentrations were diminishing, especially with cephalothin and cephapirin whose serum concentrations are rapidly declining. The significance of bactericidal concentrations in breast milk remains to be evaluated.

Minimum inhibitory concentrations (MICs) of cefadroxil were determined for 749 defined clinically-significant bacteria isolated in a London teaching hospital and for 63 strains from an international collection of Gram-negative bacilli. Assuming a breakpoint of 16 mg/l, for the hospital isolates 81.8% of Gram-negative bacilli and 83.4% of Gram-positive cocci were sensitive. No significant difference between in-patient, out-patient or community-acquired isolates was found. Ninety-five and a half per cent of Escherichia coli, Klebsiella aerogenes (including gentamicin-resistant strains), Proteus mirabilis, and (with the exception of Streptococcus faecalis and methicillin-resistant Staphylococcus aureus) all Gram-positive cocci were sensitive. Of 41 strains of Enterobacter spp., were resistant. Most indole-positive Proteus, and all Serratia and Acinetobacter spp. were resistant, including 36 additional strains taken from an international collection. Of 30 strains of Haemophilus influenzae, only six had MICs of 16 mg/l or less. For disc susceptibility testing, the standard disc containing 30 micrograms of cefadroxil reliably gave zones of greater than 17 mm for organisms with MICs of less than 16 mg/l. A zone of less than 14 mm corresponded to MICs of greater than 64 mg/l. Despite a lack of controlled clinical trials, the results of this study (taken with favourable pharmacokinetics) suggest that cefadroxil has potential as an oral cephalosporin in hospital practice in the U.K.

A total of 1979 invitations to participate in the survey were sent, and 253 responses were received during the 4-month study period. Of respondents, 81% were in private practice. Respondents averaged 21 ± 9 years in practice, and 34 ± 50 implant-based breast reconstructions were performed per year. A majority of surgeons used chlorhexidine to prepare the surgical site (52%), a triple antibiotic soak for the implant prior to placement (50%) and povidone-iodine for implant pocket irrigation (44%). A no-touch technique utilizing the Keller funnel was adopted by 69% of surgeons. Regarding antibiotic use in the postoperative period, first-generation cephalosporins (eg, cephalexin, cefadroxil) were used by a majority of surgeons (84%), and the most common duration was until drain removal (45%).

The frequency of symptomatic relapses following various antibiotic treatments for group A beta-hemolytic streptococcal tonsillopharyngitis was evaluated in 1080 pediatric patients. Within 5 days of completing therapy, the rank-order frequency of treatment failures was (1) penicillin, (2) amoxicillin, (3) first-generation cephalosporins, (4) beta-lactamase stable cephalosporins and amoxicillin-clavulanate ( P = .005). Retreatment of symptomatic failures resulted in another symptomatic relapse more often with penicillin than with cephalosporins (P = .02). Clinicians should be aware that the rate of symptomatic failures after antibiotic therapy for group A beta-hemolytic streptococcal tonsillopharyngitis differs by drug and is not an uncommon event.

A reversed-phase column liquid chromatographic method was developed for the assay of cefadroxil in bulk drugs and pharmaceutical preparations. An equation was derived showing a linear relationship between peak-area ratios of cefadroxil to dimethylphthalate (internal standard) and the cefadroxil concentration over a range of 0.02-0.8 mg/ml (r = 0.9999). Standard addition recoveries were generally greater than 97.7%. The coefficients of variation in the within-day assay were between 0.36 and 0.65, and in the between-day assay was 0.71%. The column liquid chromatographic assay results were compared with those obtained from a microbiological assay, which indicated that the proposed method is a suitable substitute for the microbiological method for potency assays and stability studies of cefadroxil preparations.

The solubility vs. pH profiles of five ionizable drugs of different nature (a monoprotic acid, a monoprotic base, a diprotic base and two amphoteric compounds showing a zwitterionic species each one) have been determined through two different methodologies: the classical shake-flask (S-F) and the potentiometric Cheqsol methods using in both instances the appropriate Henderson-Hasselbalch (H-H) or derived relationships. The results obtained independently from both approaches are consistent. A critical revision about the influence of the electrolyte used as buffering agent in the S-F method on the obtained solubility values is also performed. Thus, some deviations of the experimental points with respect the H-H profiles can be attributed to specific interactions between the buffering electrolyte and the drug due to the hydrotrophic character of citric and lactic acids. In other cases, the observed deviations are independent of the buffers used since they are caused by the formation of new species such as drug aggregates (cefadroxil) or the precipitation of a salt from a cationic species of the analyzed compound (quetiapine).

Cefatrizine, a new orally administered cephalosporin, was tested against 400 clinical isolates. Cefatrizine had excellent activity against gram-positive cocci, inhibiting all except enterococci at minimal inhibitory concentrations below 1 mug/ml. Cefatrizine inhibited the majority of Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Salmonella at concentrations below 12.5 mug/ml. Although cefatrizine was not hydrolyzed by many beta-lactamases, it did not inhibit a number of strains of Enterobacter, Serratia, or indole-positive Proteus. Cefatrizine was more active than cephalothin or cephalexin against E. coli, Klebsiella, Enterobacter, Citrobacter, Salmonella, and Shigella. Its overall activity was less than that of cefoxitin against strains resistant to cephalothin, but its activity against cephalothin-susceptible strains was equivalent to that of cefamandole.

In this review, the principal drugs used for prevention and treatment of pain--analgesics, and swelling--antibiotics, are examined. The rationale for prevention of pain and swelling is given. Then the specific drugs are considered. The analgesics evaluated include: the non-steroidal anti-inflammatory agents (e.g., aspirin, acetaminophen, ibuprofen, diflunisal); and the narcotics (e.g., codeine, oxycodone, hydrocodone, meperidine). The antibiotics evaluated include: the penicillins (e.g., penicillin V, ampicillin, methicillin); the cephalosporins (e.g., cephalexin, cefadroxil); the erythromycins (e.g., erythromycin stearate, erythromycin base); clindamycin; metronidazole; and some rarely used drugs (e.g., ciprofloxacin).

Eight Italian clinical centers carried out a controlled double-blind/double-dummy evaluation of the effectiveness of two different administration schedules of cefatrizine, an orally active cephalosporin. The first schedule provided for once-a-day administration of 1.5 gm of the drug, and the second one for twice-a-day administration of 0.75 gm. The trial included 160 patients affected by bacterial diseases of the respiratory apparatus. The two drug administration schedules were found to be equivalent in clinical and bacteriological results and in tolerability.

Neuropeptide inactivation is generally thought to occur via peptidase-mediated degradation. However, a recent study found increased analgesia after L-kyotorphin (L-Tyr-L-Arg; L-KTP) administration in mice lacking an oligopeptide transporter, PEPT2. The current study examines the role of PEPT2 in L-KTP uptake by astrocytes and compares it to astrocytic L-KTP degradation. L-[(3)H]KTP uptake was measured in primary cultures of neonatal astrocytes from rats and from Pept2(+/+) and Pept2(-/-) mice. Uptake was further characterized using potential inhibitors. L-[(3)H]KTP degradation was examined in primary astrocyte cultures from Pept2(-/-) mice by following the formation of L-[(3)H]tyrosine. The uptake of L-[(3)H]KTP in both rat and Pept2(+/+) mouse neonatal astrocytes was inhibited by known PEPT2 inhibitors. L-[(3)H]KTP uptake was also reduced in Pept2(-/-) astrocytes as compared to those from Pept2(+/+) mice. Kinetic analysis indicated the presence of a high affinity (K(m) approximately 50 microM) transporter for L-[(3)H]KTP, identified as Pept2, and a low affinity transporter (K(m) approximately 3-4 mM), inhibited by amastatin, bestatin and tyrosine. Astrocytes also degraded L-KTP through a low affinity peptidase (K(m) approximately 2 mM). Astrocytic clearance of L-KTP occurs via both peptidase activity and transport. These processes occur at similar rates and may be linked. This supports the contention that oligopeptide transport may have an impact on the extracellular clearance (and potentially activity) of certain neuropeptides.

Oral cephalosporins (cefixime, cefdinir, cefetamet, ceftibuten, cefpodoxime, loracarbef, cefprozil, cefuroxime, cefaclor, cefadroxil and BAY 3522) were compared by their antibacterial profile including stability against new beta-lactamases. Both activity and antibacterial spectrum of compounds structurally related to third generation parenteral cephalosporins (of the oximino class) were superior to established compounds. Activity against staphylococci was found to be highest for cefdinir, cefprozil and BAY 3522. Cefetamet, ceftibuten and cefixime demonstrate no clinically meaningful antistaphylococcal activity while the other compounds investigated demonstrate intermediate activity. The antibacterial spectrum was broadest for cefdinir and cefpodoxime. New oral cephalosporins are equally inactive as established compounds against Enterobacter spp., Morganella, Listeria, Pseudomonas and Acinetobacter spp., methicillin-resistant staphylococci, Enterococcus spp., penicillin-resistant pneumococci and anaerobes. New extended broad-spectrum betalactamases (TEM-3, TEM-5, TEM-6, TEM-7, SHV-2, SHV-3, SHV-4, SHV-5, CMY-1, CMY-2, and CTX-M) are active against the majority of oral cephalosporins. Ceftibuten, cefetamet, cefixime and cefdinir were stable against some of these enzymes even to a higher extent than parenteral cephalosporins. New oral cephalosporins should improve the therapeutic perspectives of oral cephalosporins due to their higher activity against pathogens marginally susceptible to established compounds (higher multiplicity of maximum plasma concentrations over MICs of the pathogens) and furthermore by including in their spectrum organisms resistant to established absorbable cephalosporins (e.g. Proteus spp., Providencia spp., Citrobacter spp., and Serratia spp.).

Cefadroxil (Duricef, Mead Johnson and Company), resembles cephalexin and cephradine in spectrum of antibacterial activity but differs in human pharmacokinetic properties. Whether the latter are likely to affect activity in vivo was assessed by determining bactericidal activity against clinical isolates under conditions simulating the variation of drug concentration in the blood stream after an oral dose of 500 mg to adults. In this kinetic model, cefadroxil was more active than cephalexin or cephradine against Staphylococcus aureus, Streptococcus pneumoniae, Klebsiella pneumoniae, Proteus mirabilis, Haemophilus influenzae and one of two strains of Escherichia coli. The other strain of E. coli was virtually unaffected by the cephalosporins. S. pyogenes was equally susceptible to all three cephalosporins. Analysis of the results suggest that the pharmocokinetic properties of an antibiotic affect its activity in the blood stream, provided the susceptibility of the infecting organism is concentration-dependent within the range of drug concentration occurring in serum.

Co-administration of piperine, an alkaloid isolated from Piper nigrum L. enhanced bioavailability of beta lactam antibiotics, amoxycillin trihydrate and cefotaxime sodium significantly in rats. The improved bioavailability is reflected in various pharmacokinetic parameters viz. tmax, Cmax, t(1/2) and AUC, of these antibiotics. The increased bioavailability could be attributed to the effect of piperine on microsomal metabolising enzymes or enzymes system.

To evaluate the effect of foal age on the pharmacokinetics of cefadroxil, five foals were administered cefadroxil in a single intravenous dose (5 mg/kg) and a single oral dose (10 or 20 mg/kg) at ages of 0.5, 1, 2, 3 and 5 months. Pharmacokinetic parameters of terminal elimination rate constant (beta(po)), oral mean residence time (MRTpo), mean absorption time (MAT), rate constant for oral absorption (Ka), bioavailability F, peak serum concentrations (Cmax) and time of peak concentration (tmax), were evaluated in a repeated measures analysis over dose. Across animal ages, parameters for the intravenous dose did not change significantly over animal age (P > or = 0.05). Mean values +/- SEM were: beta(IV) = 0.633 +/- 0.038 h-1; Cl = 0.316 +/- 0.010 L/kg/h; Vc = 0.196 +/- 0.008 L/kg; Varea = 0.526 +/- 0.024 L/kg; VSS = 0.374 +/- 0.014 L/kg; MRTiv = 1.22 +/- 0.07 h; Kel = 1.67 +/- 0.08 h-1. Following oral administration, drug absorption became faster with age (P < 0.05), as reflected by MRTpo, MAT, Ka and tmax. However, oral bioavailability (+/- SE) declined significantly (P < 0.05) from 99.6 +/- 3.69% at 0.5 months to 14.5 +/- 1.40% at 5 months of age. To evaluate a dose effect on the pharmacokinetic parameters, a series of oral doses (5, 10, 20 and 40 mg/kg) were administered to these foals at 1 month of age. beta(po) (0.548 +/- 0.023 h-1) and F (68.26 +/- 2.43%) were not affected significantly by the size of the dose. Cmax was approximately doubled with each two-fold increase in dose: 3.15 +/- 0.15, 5.84 +/- 0.48, 12.17 +/- 0.93 and 19.71 +/- 2.19 micrograms/mL. Dose-dependent kinetics were observed in MRTpo, MAT, Ka and tmax.

In order to study the interaction of sulfamoyl- and phenoxy diuretics as well as of beta-lactam antibiotics with the contraluminal anion and cation transport systems the inhibitory potency of these substances against the influx of 3H-para-aminohippurate, 14C-succinate, 35S-sulfate and 3H-N1-methylnicotinamide into cortical tubular cells have been determined. 1.) 2-, 3- and 4-sulfamoylbenzoate inhibit contraluminal PAH influx. N-dipropyl substitution to yield probenecid or ring-substitution to yield furosemide and piretanide augment the inhibitory potency. However, hydrochlorothiazide and acetazolamide exert only a moderate inhibitory potency. Succinate transport was inhibited by furosemide only. Sulfate transport was inhibited by furosemide and 3-sulfamoyl-4-phenoxybenzoate as well as by probenecid, piretanide, hydrochlorothiazide and acetazolamide. 2.) Phenoxyacetate, -propionate, and -butyrate exert increasing inhibition against PAH transport. The weed-killers 2,4-dichloro-, and 2,4,5-trichlorophenoxyacetate (2,4 D and 2,4,5 T) had a similar inhibitory potency, while ethacrynic acid showed a lower and the uricosuric tienilic acid a higher inhibitory potency. None of the compounds of this group interact with contraluminal succinate transport, and only the multiring-substituted compounds 2,4 D, 2,4,5 T, ethacrynic and tienilic acid interact slightly with the sulfate transporter. 3.) The monocarboxylic penicillins benzylpenicillin and phenoxymethylpenicillin as well as the dicarboxylic ticarcillin interact with the contraluminal PAH transport. The aminopenicillin ampicillin had a lower, and apalcillin a higher inhibitory potency than monocarboxylic penicillin. Benzylpenicillin showed small inhibition against succinate transport and ticarcillin against sulfate transport. 4.) The monocarboxylic cephalosporine, 6315 S Shionogi, and the aminocephalosporines, cephalexin and cefadroxil, showed an app. Ki.PAH as the comparable penicillins. The zwitterions cephaloridine and cefpirome did not interact with the PAH transporter, but with the organic cation (NMN) transporter. Amongst the amino-thiazol-containing compounds cefotaxime, ceftriaxone, and cefodizime, increasing interaction with the PAH transporter was seen dependent of a second ionizable anionic group. Compounds with two ionizable anionic groups (cefsulodin, ceftriaxone, cefodizime) exert also a small inhibitory potency against sulfate transport. None of the cephalosporins interacted with the dicarboxylate transporter. The interaction pattern of the tested compounds is in accordance with the specificity requirements for the contraluminal transporters depending on electrical charge and hydrophobicity.

The in vitro activity of ampicillin, amoxicillin/clavulanate, cefadroxil, cefaclor, cefuroxime (axetil), co-trimoxazole, doxycycline, ciprofloxacin, ofloxacin, erythromycin, and roxithromycin was tested against unselected isolates of S. pneumoniae (70), H. influenzae (93), and M. catarrhalis (46), cultured from clinically significant sputum samples of general practice patients. All isolates of S. pneumoniae were highly susceptible to ampicillin; cefadroxil and cefaclor were markedly less active on a weight basis; resistance was only observed with co-trimoxazole (4.3%), doxycycline (5.7%), and erythromycin (2.9%); however, ciprofloxacin and ofloxacin showed median MICs (MIC50), that were only one dilution below breakpoint. Beta-lactamase was detected in 14.0% of H. influenzae isolates; all isolates were susceptible to amoxicillin/clavulanate, cefaclor, and cefuroxime (axetil), although MICs were generally higher for cefaclor; the highest activity was exhibited by ciprofloxacin and ofloxacin; apart from cefadroxil, erythromycin, and roxithromycin, that showed only marginal activity, resistance was observed with co-trimoxazole (4.3%) and doxycycline (1.1%). All (including 71.7% of beta-lactamase producing) isolates of M. catarrhalis were susceptible to amoxicillin/clavulanate, cefaclor and cefuroxime (axetil), although MICs were markedly lower for amoxicillin/clavulanate; ciprofloxacin and ofloxacin showed the lowest MICs; resistance was only observed with cefadroxil (2.2%). In conclusion, the antimicrobial agents showing the most uniformly high in vitro activity against the 3 common community respiratory pathogens tested in the present study, were amoxicillin/clavulanate and, to a lesser extent, cefuroxime (axetil).

The transport characteristics of chemically modified phenylalanylglycine (Phe-Gly) with butyric acid (C4-Phe-Gly) and caproic acid (C6-Phe-Gly) were examined using rabbit intestinal brush-border membrane vesicles (BBMVs). In the presence of an inwardly H+ gradient (pH 7.5 inside, pH 6.0 outside), the uptake of Phe-Gly via BBMVs was significantly enhanced by the covalent attachment of butyric or caproic acid to the N-terminal of Phe-Gly. Moreover, C4-Phe-Gly uptake was stimulated by the trans-stimulation effect of some dipeptides and cefadroxil, and was inhibited by other dipeptides and cefadroxil. These results indicate that N-terminal modified Phe-Gly with fatty acids are transported into BBMVs via an oligopeptide transporter. Therefore, chemical modification of dipeptides with fatty acids can enhance the intestinal absorption of dipeptide by a carrier-mediated transport via an oligopeptide transporter.

The cephalosporin antibiotics have been employed with increasing frequency since their introduction into clinical practice in the early 1960s. With the exception of cephaloridine, cephalosporin compounds are not associated with the production of significant untoward effects. The availability of newer cephalosporins, both oral and parenteral, with enhanced antibacterial activity, has expanded the clinical indications for administration of these antibiotics.

Antimicrobial agents have greatly reduced the incidence of intracranial complications of infections of the middle ear and mastoid. Too many prescriptions and overconsumption of antibiotics when otitis media is suspected has caused resistance to many antibiotics, leading to a pronounced and justifiable desire to reduce the widespread excessive use of antibiotics. The possible untoward consequences of a too restricted antibiotic policy, however, is illustrated by the following case of a 14-year-old boy who, after non-treatment of an ear infection, fell ill with one-sided headache and vomiting caused by a lateral sinus thrombosis. After intravenous treatment with antibiotics, anticoagulants and ventilation of the middle ear, the infection was cured without complications. This case calls attention to the symptoms of otitic complications arising outside the temporal bone. The physician must always bear in mind the possibility of an unusual event. The general treatment of endocranial complications is outlined, giving details of the treatment given in this special case. We stress that one should not be too cautious in prescribing antibiotics in otitis media.

The transport of dipeptides and beta-lactam antibiotics across the rat renal basolateral membrane was examined. The initial uptake of glycylsarcosine and cefadroxil by rat renal basolateral membrane vesicles was inhibited by the presence of all the di- and tripeptides and beta-lactam antibiotics that were tested in this study. However, the uptake of both substrates was not inhibited by glycine, an amino acid. The initial uptake of zwitterionic beta-lactam antibiotics, cefadroxil, cephradine, and cephalexin, was stimulated by preloaded glycylsarcosine (countertransport effect). On the other hand, the uptake of dianionic beta-lactam antibiotics, ceftibuten and cefixime, was not affected. A concentration-dependent initial uptake of glycylsarcosine and cefadroxil suggested the existence of a carrier-mediated mechanism, whereas the transport of ceftibuten did not show any saturated uptake. The transporter that participates in the permeation of dipeptides and beta-lactam antibiotics across basolateral membranes showed lower affinity than did PEPT1 and PEPT2. This is the first study that showed an evidence for a peptide transporter, expressed in the rat renal basolateral membrane, that recognizes zwitterionic beta-lactam antibiotics using basolateral membrane vesicles isolated from normal rat kidney.

Cefetamet pivoxil is an oral third-generation cephalosporin which is hydrolysed to form the active agent, cefetamet. Cefetamet has excellent in vitro activity against the major respiratory pathogens Streptococcus pneumoniae, Haemophilus influenzae, Moraxella (Branhamella) catarrhalis and group A beta-haemolytic streptococci; it is active against beta-lactamase-producing strains of H. influenzae and M. catarrhalis, but has poor activity against penicillin-resistant S. pneumoniae. Cefetamet has marked activity against Neisseria gonorrhoeae and possesses a broad spectrum of activity against Enterobacteriaceae. Both staphylococci and Pseudomonas spp. are resistant to cefetamet. Cefetamet pivoxil has been investigated in the treatment of both upper and lower community-acquired respiratory tract infections and has demonstrated equivalent efficacy to a number of more established agents, namely cefaclor, amoxicillin and cefixime. In patients with group A beta-haemolytic streptococcal pharyngotonsillitis, a 7-day course of cefetamet pivoxil was as effective as a 10-day course of the standard agent, phenoxymethylpenicillin, in this indication. In complicated urinary tract infections, cefetamet pivoxil showed similar efficacy to cefadroxil, cefaclor and cefuroxime axetil. Cefetamet pivoxil was effective in the treatment of otitis media, pneumonia, pharyngotonsillitis and urinary tract infections in children. Preliminary data indicate that single dose cefetamet pivoxil can effectively eradicate N. gonorrhoeae from both men and women. Cefetamet pivoxil has a tolerability profile similar to that of other oral cephalosporins, with gastrointestinal effects being the most commonly reported adverse events. To date, no symptoms of carnitine deficiency have been reported with cefetamet pivoxil. Cefetamet pivoxil offers effective alternative oral therapy for outpatient treatment of community-acquired respiratory tract infections, with the advantage of improved activity against H. influenzae and increased beta-lactamase stability. However, its use in areas with a high incidence of penicillin-resistant S. pneumoniae is likely to be limited. Cefetamet pivoxil is also effective in the treatment of urinary tract infections, although further trials are required to define any comparative advantages over other oral agents.

Uptake of cefadroxil and its two acetyl-derivatives, N-acetyl- and O-acetyl-cefadroxil, into the brush-border membrane vesicles (BBMV) was measured at [pH]o = 5.5, 7.4 and [pH]i = 7.4. Both acetyl-derivatives showed a significantly slower uptake than cefadroxil at [pH]o = 5.5 and 7.4. Cefadroxil and the two derivatives showed a higher uptake rate in the presence of an inward H+ gradient ([pH]o = 5.5, [pH]i = 7.4). At [pH]o = 5.5, uptake of cefadroxil into BBMV was inhibited by N-acetyl-, O-acetyl-, N-BOC-, and N-BOC-O-acetyl-cefadroxil, but not by cephalothin and cefuroxime. At [pH]o = 7.4, no inhibition of cefadroxil uptake was evident for any inhibitors. There were two different transporters responsible for the uptake of cefadroxil at pH 5.5 and 7.4. One is the H(+)-coupled dipeptide transport system, and the other is the neutral pH-preferring system. The alpha-amino group may be essential for the transport of cefadroxil by both transport systems. Although the phenolic group in the side chain is not an essential functional group of beta-lactam antibiotics, an additional derivation on the phenolic group of cefadroxil also inhibited both the H(+)-coupled dipeptide transport system and the neutral pH-preferring transport system.

Baicalin (baicalein-7-glucuronide) is a flavonoid purified from Scutellaria baicalensis Georgi that has traditionally been used for treatment of hypertension, cardiovascular diseases, and viral hepatitis. In this study, the effects of intestinal microbiota on the pharmacokinetics of baicalin were investigated in normal and antibiotic-pretreated rats following p.o. administration of 100 mg/kg baicalin by using liquid chromatography/ion trap mass spectrometry. When rats were pretreated orally with cefadroxil, oxytetracycline and erythromycin for 3 days to control the number of intestinal bacteria, the pharmacokinetic parameters of oral baicalin were significantly affected by antibiotics: Cmax, T1/2(β), Kel and AUC values were significantly changed compared to those in normal rats. These results indicate that intestinal microbiota might play a key role in the oral pharmacokinetics of baicalin.

The minimal inhibitory concentrations (MIC) of cephalexin, cephradine, cefaclor, cefatrizine and cefadroxil for Salmonella species, Escherichia coli and Pasteurella multocida isolated previously from young calves were determined. The MIC90 values for cephalexin, cephradine and cefadroxil ranged between 3.12 micrograms ml-1 and 12.5 micrograms ml-1, whereas those of cefatrizine and cefaclor were 3.12 micrograms ml-1 and 0.78 microgram ml-1, respectively. Each drug was administered intravenously and orally to groups of pre-ruminating calves and orally to early ruminating calves. Although the pharmacokinetic characteristics of the drugs after intravenous injection were similar to other beta-lactam antibiotics, significant differences between the cephalosporins examined were found in respect of certain kinetic parameters. The drugs showed rapid absorption into the systemic circulation after oral administration to pre-ruminating calves but the elimination half-life values (t1/2 beta) varied between three hours (cefaclor and cefadroxil) and nine hours (cefatrizine). The bioavailability of the drugs was about 35 per cent of the administered dose. Co-administration of probenecid with each antibiotic caused a twofold or greater increase in peak serum drug concentrations (Cmax) but the effect on t1/2 beta was variable. Cephalexin, cephradine and cefaclor given to the ruminating calves resulted in very low serum or plasma concentrations and their use should be restricted to younger calves. Cefadroxil was found to give the highest serum concentrations in this age group but had significantly lower bioavailability when compared with the unweaned calves. Provisional oral dosage regimens were computed for each cephalosporin on the basis of the MIC data and the kinetic parameters derived from intravenous and oral drug administration.

Transporters (OATs, MRPs, and perhaps OATPs) that can be inhibited by probenecid play an important role in mediating the brain-to-blood efflux of cefadroxil at the BBB. The uptake of cefadroxil in brain cells involves both the influx transporter PEPT2 and efflux transporters (probenecid-inhibitable). These findings demonstrate that drug-drug interactions via relevant transporters may affect the distribution of cephalosporins in both brain ECF and ICF.

The sample is placed in the sample vessel of a RH cell and the moisture content of the air flow is controlled. From the RH cell the air flow is conducted into a subsequent perfusion cell in which a saturated salt solution has been loaded. The RH cell and perfusion cells are positioned in the sample sides of two twin calorimetric units. Depending on the moisture content in the outlet flow leaving the preceding RH cell, the heat flow signal from the subsequent perfusion cell will vary. By means of blank measurement with identical settings, the rate of water sorption can be calculated and, by integration, the amount of sorbed water is obtained.

The in vitro activity of cefatrizine was evaluated against 294 Gram-positive and 270 Gram-negative bacteria isolated from clinical specimens. Cefatrizine had excellent activity against Gram-positive cocci, inhibiting all except enterococci at minimal inhibitory concentrations below 1 mcg/ml. Moreover, cefatrizine was an buy duricef online effective antibacterial agent for most major Gram-negative species. Cefatrizine activity was tested against 34 strains of H. influenzae and 37 strains of K. pneumoniae and compared with that of other orally administered cephalosporins. Cefatrizine MIC50 values were much lower than those recorded for cephalexin and cefadroxil.

The in vitro activity of 10 cephalosporin antimicrobial agents against 75 isolates of methicillin-susceptible Staphylococcus pseudintermedius derived from dogs was assessed. The lowest minimal inhibitory concentration for 90% of strains (MIC90) values obtained were for cephalothin, cefovecin, and cefazolin (0.12 ug/mL), followed by ceftiofur and cefoxitin (0.25 ug/mL), cefpodoxime (0.5 ug/mL), and cefaclor and cefadroxil (1 ug/mL). The highest MIC90 values were found for cephalexin and cefixime (2 ug/mL). In this in vitro study, sensitivity to cephalothin was indicative of cephalexin susceptibility, although there were marked differences in MICs. Cephalothin susceptibility was not indicative of susceptibility to all tested cephalosporins, nor was there a clear trend in susceptibility based buy duricef online on cephalosporin generation.

Clinical studies have been carried out world-wide on cefetamet pivoxil, a new orally active cephalosporin. This paper reports on the first 1000 patients treated with the antibiotic; another 505 patients received standard antibiotics, mainly cefadroxil and cefaclor, for comparison. The results show that single doses of 1500 and 1200 mg cefetamet pivoxil were fully effective in gonorrhoea. Comparative trials in uncomplicated urinary tract infection indicate a significant superiority of a single dose of 2 g cefetamet pivoxil (n = 158; 90.0% cure) versus 2 g cefadrox (n = 162; 77.0% cure). In complicated urinary tract infections, a comparable outcome was achieved with a single daily dose of 2 g cefetamet pivoxil for 10 days (n = 99; 90% cure) and 1 g cefadroxil twice daily for 10 days (n = 98; 76.5% cure). The clinical response rate in acute exacerbation of chronic bronchitis was 89.4% in the group receiving cefetamet pivoxil (136 patients) and 83% in the cefaclor-treated group (n = 122). Treatment with 1000 or 2000 mg cefetamet pivoxil achieved a (bacteriological) success rate of 96% compared to 95% with cefaclor in acute ear, nose and throat-infections (n = 91). Overall, based on 894 isolated pathogens prior to therapy, the bacteriological response rate was 90% and it would appear that in vivo the spectrum of this cephalosporin covers a wide range of Gram-negative and Gram-positive pathogens, including urinary pathogens, but excluding Enterococci and Pseudomonas. Cefetamet pivoxil proved to be well tolerated. Mild to moderate adverse events were reported in 7.1% of patients but only 2 of the 1000 patients treated with cefetamet pivoxil were withdrawn because of diarrhoea, which subsided rapidly. There were buy duricef online no clinically relevant deviations in laboratory parameters.

Cefixime is a new orally absorbed iminomethoxy, aminothiazolyl cephalosporin. It inhibits the majority, 90%, of Streptococcus pneumoniae, Streptococcus pyogenes, Branhamella catarrhalis, Haemophilus influenzae, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis and Neisseria gonorrhoeae at concentrations less than or equal to 0.25 micrograms/ml. It inhibits 90% of the other members of the Enterobacteriaceae buy duricef online at concentrations less than 1 microgram/ml, with the exception of some strains of Enterobacter spp., Citrobacter freundii and Morganella morganii, Cefixime does not inhibit enterococci, Listeria, Pseudomonas aeruginosa, Acinetobacter, Bacteroides spp. or staphylococci. In general, cefixime has in vitro activity superior to cephalexin, cephradine, cefadroxil and cefaclor against all bacteria with the exception of staphylococci. Cefixime is not destroyed by most of the common plasmid and chromosomal beta-lactamases and its activity is not reduced by serum, blood or urine. Cefixime overall has excellent in vitro activity against the commonly encountered respiratory and urinary tract pathogens.

Cefditoren pivoxil is an orally absorbed prodrug that is rapidly hydrolysed by intestinal esterases to the microbiologically active cephalosporin cefditoren. Cefditoren has a broad spectrum of activity against Gram-positive and Gram-negative bacteria, including common respiratory and skin pathogens. Cefditoren has shown excellent in vitro activity against the Gram-positive pathogens penicillin-susceptible and -intermediate Streptococcus pneumoniae, S. pyogenes and methicillin-susceptible Staphylococcus aureus. Cefditoren was inactive against methicillin-resistant S. aureus. Of the important Gram-negative pathogens, cefditoren had potent antibacterial effects against beta-lactamase-positive and -negative Haemophilus influenzae, H. parainfluenzae and beta-lactamase-positive and -negative Moraxella catarrhalis. Cefditoren does not have antibacterial activity against Pseudomonas aeruginosa or atypical respiratory pathogens and has only variable activity against anaerobes. In healthy volunteers, single doses of cefditoren pivoxil 200 and 400mg achieved maximal plasma concentrations of 2.6 to 3.1 mg/L and 3.8 to 4.6 mg/L, respectively. Cefditoren penetrates rapidly into bronchopulmonary and tonsillar tissue as well as inflammatory and noninflammatory blister fluid. In two, randomised, double-blind trials involving patients with acute exacerbations of chronic bronchitis (AECB), cefditoren 200 and 400mg twice daily for 10 days produced clinical cure rates of 88 to 89% within 48 hours of treatment completion. Clinical cure rates in patients with AECB were similar to those of either clarithromycin 500mg twice daily or cefuroxime axetil 250mg twice daily. In patients with streptococcal pharyngitis, a 10-day course of cefditoren pivoxil 200mg twice daily produced clinical cure rates of 94% at 4 to 7 buy duricef online days after treatment, which were similar to those observed for phenoxymethylpenicillin potassium 250 mg four times daily. In uncomplicated skin and skin structure infections, a 10-day course of cefditoren pivoxil 200 or 400mg twice daily produced the same clinical cure rate of 89% within 48 hours of treatment completion. These cefditoren pivoxil dosage regimens were as effective as a 10-day course of either cefadroxil 500 mg twice daily or cefuroxime axetil 250mg twice daily in treating uncomplicated skin and skin structure infections, including those caused by S. aureus and S. pyogenes. The most common adverse events associated with therapeutic doses of cefditoren pivoxil are diarrhoea, nausea, headache, abdominal pain and vaginal candidiasis.

A new chemiluminescence reaction, the luminol-Cu(2+) reaction, was investigated for the determination of thirteen (13) cephalosporin antibiotics, namely cefalexin, cefadroxil, cefradine, cefazolin sodium, cefaclor, cefuroxime axetil, cefotaxime sodium, cefoperazone sodium, ceftriaxone sodium, buy duricef online ceftazidime, cefetamet pivoxil hydrochloride, cefixime, and cefpodoxime. It was found that, without adding any special oxidant, strong chemiluminescent (CL) signal could be produced from the reaction of the alkaline luminol with the above-mentioned antibiotics in the presence of Cu(2+). The experimental conditions for the reaction were carefully optimized with flow-injection mode. The detection limits are 0.3 ng/mL cefalexin, 3 ng/mL cefadroxil, 0.3 ng/mL cefradine, 0.02 μg/mL cefazolin sodium, 0.8 ng/mL cefaclor, 0.02 μg/mL cefuroxime axetil, 5 ng/mL cefotaxime sodium, 0.02 μg/mL cefoperazone sodium, 0.8 ng/mL ceftriaxone sodium, 1 ng/mL ceftazidime, 0.08 ng/mL cefetamet pivoxil hydrochloride, 0.8 ng/mL cefixime, and 2 ng/mL cefpodoxime. The proposed method was validated by direct application to commercial formulations and spiked milk samples containing cefradine. A possible reaction mechanism is also discussed.

Pharmacological and antimicrobial properties of cefadroxil, a new cephalosporin antibiotic, were compared with cephalexin. Absorption and excretion were studied in 20 healthy men. Peak concentrations of the drugs in serum were similar after ingestion of single 500-mg tablets. The concentration of cefadroxil in serum was more sustained than that of cephalexin. Levels of cefadroxil in serum after a dose of 1,000 mg were approximately twice those after a 500-mg dose through 6 h. Each drug administered in a dose of 500 mg every 6 h for 24 h resulted in concentrations in serum that were similar to a single dose without accumulation. Ninety-three percent of the cefadroxil and 85% of the cephalexin were excreted in urine after ingestions of single 500-mg tablets. The urine concentration of cefadroxil was more sustained than cephalexin. Minimal inhibitory and minimal bactericidal concentrations for clinical isolates were comparable with each drug. Cefadroxil compares buy duricef online favorably with cephalexin in this study. Sustained levels of cefadroxil in serum and urine suggest that this drug may be given at less frequent intervals than cephalexin.

The association conjunctivitis-otitis is highly suggestive of Haemophilus influenzae infection. This conjunctivitis otitis syndrome could be a good model to assess the efficacy of different antibiotic regimen in the treatment of acute otitis media due to HI without tympanocentesis. This prospective randomized trial compared the efficacy of two orally cephalosporins which demonstrate in vitro an activity against HI. This study was conducted Flonase Generic Brand from 4.20.1988 to 3.15.1989 and involved 73 children with COS examined in an outpatient clinic. The mean age was 17.7 months. Before treatment culture were taken from the lower palpebral conjunctivae. 81 strains was found: HI 61 (beta-lactamase-producing 15), Streptococcus pneumoniae 16, Branhamella Catarrhalis 4. The 73 patients were treated with 40 to 50 mg/kg/day of the test drug for ten days, 25 with Cefaclor in 3 divided dose (group 1), 24 with Cefatrizine in 3 divided dose (group 2), 24 with Cefatrizine in 2 divided dose (group 3). The recoveries was obtained in 17/25 in the group 1, 18/24 in the group 2, 15/24 in the group 3. There was no significant difference between the 3 groups.

The reabsorption of filtered di- and tripeptides as well as certain peptide mimetics from the tubular lumen into renal epithelial cells is mediated by an H+-coupled high-affinity transport process. Here we demonstrate for the first time H+-coupled uptake of dipeptides into the renal proximal tubule cell line LLC-PK1. Transport was assessed 1) by uptake studies using the radiolabeled dipeptide D-[3H]Phe-L-Ala, 2) by cellular accumulation of the fluorescent dipeptide D-Ala-Lys-AMCA, and 3) by measurement of intracellular pH (pHi) changes as a consequence of H+-coupled dipeptide transport. Uptake of Glucotrol 10mg Tab D-Phe-L-Ala increased linearly over 11 days postconfluency and showed all the characteristics of the kidney cortex high-affinity peptide transporter, e.g., a pH optimum for transport of D-Phe-L-Ala of 6.0, an apparent Km value for influx of 25.8 +/- 3. 6 microM, and affinities of differently charged dipeptides or the beta-lactam antibiotic cefadroxil to the binding site in the range of 20-80 microM. pHi measurements established the peptide transporter to induce pronounced intracellular acidification in LLC-PK1 cells and confirm its postulated role as a cellular acid loader.

This study was designed to determine whether serum C-reactive protein (CRP) concentrations could be used to identify children with uncomplicated lower urinary tract infection who would respond favorably to short-term antibiotic therapy. A one-day or ten-day regimen of cefadroxil (30 mg/kg/day in two divided doses) was assigned randomly to 80 children who had acute urinary tract infection and CRP concentrations less than 28 microgram/ml (CRP-negative group). Ten days of cefadroxil therapy was used to treat 44 children with urinary tract infection and CRP values greater than or equal to 28 microgram/ml (CRP-positive group). The clinical and laboratory characteristics of the children in the two CRP-negative therapy groups were similar to, but different from those of children with CRP-positive infections. Recurrent infections occurred significantly more often at four to five days after completion of therapy in CRP-negative children who received one day (44.4%) compared to ten days (20%) of cefadroxil therapy (P less than .05). When data from this study were combined with those from our previously published investigation of short-term antibiotic therapy in CRP-negative children, a significantly larger percentage of recurrences was documented immediately after one or four Luvox Mg days of antibiotics (79%) compared to recurrences after the standard ten-day regimen (41%). Additionally, the total rate of recurrent infections for all children in both studies was significantly larger in those who received short-term therapy (48%) as opposed to conventional therapy (34%). These data indicate that short-term antibiotic therapy is less effective than the conventional ten-day regimen in children with CRP-negative urinary tract infection.

The intracellular content of glutathione in astroglia-rich primary cultures derived from the brains of newborn rats was used as an indicator for the ability of these cultures to utilize cysteinylglycine (CysGly) for Betnovate Buy Online glutathione synthesis. After a 24-h starvation period in the absence of glucose and amino acids, CysGly was able to substitute for cysteine plus glycine in the restoration of glutathione. Glutathione restoration from CysGly plus glutamate was only slightly affected by the dipeptides carnosine or serylglycine in a 200-fold excess. Captopril, a substrate of the peptide transporter PepT1, had almost no effect on glutathione restoration. In contrast, with increasing concentrations of alanylalanine or cefadroxil, known substrates of the peptide transporter PepT2, the amount of glutathione restored in the presence of CysGly and glutamate was strongly reduced. Cefadroxil in a 200-fold excess totally prevented the utilization of CysGly for glutathione restoration. The presence of mRNA for PepT2 in astroglia-rich primary cultures was demonstrated by application of RT-PCR. These results demonstrate that PepT2 is expressed in astroglia-rich primary cultures and that this transporter is highly likely to be responsible for the uptake of CysGly in these cultures.

The therapeutic efficacy of 25 mg/kg of cefadroxil administered once daily was compared with that of 50 mg/kg/day of ampicillin administered in four equal doses in the treatment of acute uncomplicated urinary tract infections (UTIs) in children. Nineteen girls and seven boys (mean age, 5.5 years) received cefadroxil, and 18 girls and eight boys (mean age, 5.9 years) received ampicillin. The clinical and bacteriological characteristics, as well as the demographic characteristics, of both populations were well matched. Patients with structural anomalies or with a history of hypersensitivity to cephalosporins or penicillins or abnormal hepatorenal function were excluded from the trial. Only patients with at least two consecutive positive cultures of a single pathogen, obtained in clean-catch midstream urine samples (greater than or equal to 10(5) colony-forming units per ml urine) and susceptible to the respective antibiotic, were admitted to the study. Urine cultures were repeated during the ten days of treatment and ten days after the completion of treatment. All patients in the cefadroxil group were evaluated as clinically and bacteriologically cured. Three (12%) of the patients in the ampicillin group had positive cultures in the immediate post-treatment period. The differences in the cure rates of the two groups were not statistically significant. No adverse effects of either antibiotic were observed.

A double-blind, randomized clinical trial was carried out to compare the effectiveness of twice daily versus once daily administration of the cephalosporin, cefatrizine, in paediatric outpatients with bacterial infection of the respiratory tract. Thirty children were studied, aged 7 years 2 months (range, 4-12 years). They were given 75 mg/kg.day cefatrizine either once daily or twice daily at 12 h intervals for 8 days. Fever, clinical symptoms, bacterial eradication and overall tolerance were evaluated. No significant differences were observed between once daily or twice daily administration. This is in agreement with other studies carried out on adults. It is concluded that cefatrizine may be given to paediatric out-patients for the treatment of bacterial infection of the respiratory tract only once daily with good clinical and overall results.
