Based on data presented here, we concluded that diterpenoids and sterols detected in the ethanolic fraction can be responsible for its pharmacological activity.

zantac dose

Histamine (60 microM) produced ATP release from segments of guinea-pig vas deferens which was blocked by pyrilamine and triprolidine, H1-blockers, but not by ranitidine, an H2-blocker. The evoked-release was inhibited by the mitochondrial inhibitors, carbonyl cyanide-m-chlorophenylhydrazone (CCCP) and oligomycin. Bradykinin (BK) and substance P (SP) also caused substantial and moderate release of ATP, respectively. The BK-evoked release of ATP was inhibited by HOE140, a B2-antagonist, but not by [Des-Arg10] HOE140, a B1-antagonist. On the other hand, VIP, angiotensin II (AII) and cholecystokinin-octapeptide (CCK-8) failed to elicit a measurable release of ATP. Histamine and BK also enhanced the release of ATP from superfused cultured smooth muscle cells. These results suggest that ATP may be released as an autacoid from the smooth muscles in the presence of these chemical mediators.

Some additional omeprazole-related properties, such as antineutrophil properties, were not observed in H. pylori-infected mice after one week of treatment, suggesting that this property is restricted to in vitro approaches. However, the antiapoptotic activity of omeprazole could be attributed to an ability to modify the protein expression of Bcl-2, decreased by H. pylori infection.

The inhibitory effect of ranitidine and cimetidine on pentagastrin stimulated volume, acid and pepsin secretion has been studied in eight healthy volunteers. Both compounds inhibit all measured components of gastric secretion in a dose dependent manner. On a molar basis ranitidine is on average 11.14 times for volume, 13.04 times for acid, and 9.74 times for pepsin secretion more potent than cimetidine as measured by the ID50-values.

As far as we know, this is the first case report of immediate hypersensitivity after Nd:YAG laser treatment of a tattoo. Prophylactic treatment with steroids and antihistamines prevented reactions with subsequent laser treatments. Reactions after laser removal are rare, but may increase as popularity of skin art increases with the need for subsequent removal.

Smoking has been shown to impair the therapeutic effect of H2-receptor antagonists. To evaluate the acid-reducing capacity of H2-receptor antagonists in relation to smoking habits, we tested the effect of ranitidine (Ran) and famotidine (Fam) under physiologic conditions, using ambulatory pH-metry. Intragastric pH was measured over 20 h. Each of 18 healthy volunteers, 9 smokers and 9 nonsmokers, received 40 mg Fam, 300 mg Ran, or placebo in a double-blind, randomized study as a single evening dose. With both drugs 20-h acidity was markedly suppressed. After Fam treatment mean inhibition was 61% in smokers and 76% in nonsmokers and after Ran 51% and 67%, respectively. When areas under the pH curves for each individual were calculated and treatment compared with placebo (= 100%), the response was smaller in smokers than in nonsmokers with either drug (Fam, 153 +/- 21% versus 214 +/- 19%, p less than 0.01; Ran, 176 +/- 21% versus 232 +/- 29%, p less than 0.05) during the first 4 h after drug intake. A similar effect was observed in the morning period from 0600 to 1000 h (Fam, 118 +/- 19% versus 206 +/- 19%, p less than 0.001; Ran, 133 +/- 21% versus 207 +/- 31%, p less than 0.02). During the nighttime there were no significant differences. These findings indicate that smoking impairs the response to both drugs tested.

pediatric zantac dosing

36 patients with chronic gastric or oesophageal peptic ulceration (including 6 with antrectomy), resistant to high-dose ranitidine treatment for at least 3 months, were successfully treated with 40-60 mg of omeprazole daily for periods between 1 and 2 years. Fasting serum gastrin levels were monitored at regular intervals during therapy and multiple gastric mucosal biopsies were taken during gastroscopy every 3-6 months. Gastrin levels increased significantly during the first 6 months of therapy from a medium level of 81.5 to 206 pg/ml, a slight decrease was seen thereafter. In 10 patients investigated before the start of the treatment and after 1 and 2 years, the volume density of argyrophilic cells in the oxyntic mucosa increased from 0.43 +/- 0.08 to 0.91 +/- 0.14% during the first year; this change was statistically significant. No further increase was observed thereafter. No such difference could be demonstrated between a larger group of 18 patients investigated before and after 1 year of treatment with omeprazole (0.806 +/- 0.1 vs. 0.93 +/- 0.08%) and between a larger group of 22 untreated patients and 17 patients treated for 17-24 months with omeprazole (0.73 +/- 0.1 vs. 0.86 +/- 0.09%). The volume density of argyrophilic cells found in 8 patients with gastrinoma amounted to 1.37 +/- 0.22%. No clusters of endocrine cells were found in omeprazole-treated patients. The D cell volume density in the antral mucosa decreased significantly during the first months of treatment, but steadily increased thereafter to reach pretreatment values after 17 months. There was no change in G cell volume density under therapy. No changes in gastrin levels or oxyntic argyrophilic cells were observed in the antrectomized patients. It is concluded that the hyperplasia of argyrophilic cells observed in some patients during long-term omeprazole treatment is mediated by hypergastrinaemia.

A total of 22 subjects (13 with gastroesophageal reflux disease and nine who served as control subjects) were prospectively evaluated by serial combined esophageal and gastric 24-h pH monitoring. Studies were performed at baseline off antireflux medical therapy and subsequent to completion of the following four drug regimens: 1) omeprazole 20 mg b.i.d. for 2 wk; 2) omeprazole 20 mg b.i.d. plus ranitidine 300 mg HS for 4 wk; 3) omeprazole 20 mg QAM and QHS for 2 wk; and 4) omeprazole 20 mg every 8 h for 2 wk. A dual pH probe was placed 5 cm above and 10 cm below the manometrically defined LES for a minimum of 18 h. Median total, upright, and supine pH values were compared among treatment regimens. All subjects underwent Helicobacter pylori serology testing.

Colonic carcinomas were induced in male Sprague-Dawley rats by six weekly intraperitoneal injections of methylazoxymethanol. Four weeks after the last injection of carcinogen, the animals were randomized into four treatment groups, including vehicle control, low- and high-dose omeprazole, and ranitidine. After 10 weeks of treatment, the animals were bled, stomach weights were recorded, and colon tumors were mapped, enumerated, measured, and scored histopathologically by Dukes' classification. Crypt and mucosal heights were determined in colonic mucosa unaffected by tumor.

zantac generic price

Gastric and duodenal injury related to nonsteroidal anti-inflammatory drug (NSAID) use is extremely common, and a variety of strategies can be employed to reduce this frequent side effect of an otherwise useful category of medications. Although the best approach may be to discontinue NSAID treatment, this is not always possible for patients with arthritis pain or for those who require low-dose aspirin therapy for underlying cardiovascular disease. In arthritis cases, one of the new cyclooxygenase-2 specific inhibitors can be used to replace a traditional NSAID, but the addition of another drug to treat and heal ulcers is normally still needed. Patients taking aspirin are also candidates for additional treatment.

Calotropis procera latex and flower extracts are toxic (50-70% mortality) even in a small dose (250 mg/kg) before washing off their toxic rubber. Zingiber officinale extract insignificantly decrease (7.26%) S. mansoni worms. When toxic rubber was washed off and ranitidine was used, C. procera (stem latex and flowers) and F. elastica extracts revealed significant S. mansoni worm reductions by 45.31, 53.7 and 16.71%, respectively. Moreover, C. procera extracts produced significant reductions in tissue egg load (∼34-38.5%) and positively affected oogram pattern.

A simple, selective and sensitive high-performance liquid chromatographic method with spectrophotometric detection was developed for the determination of antihyperglycemic agent metformin in human plasma using a novel sample extraction procedure. Liquid-liquid extraction of metformin and ranitidine (as internal standard) from plasma samples was performed with 1-butanol/n-hexane (50:50, v/v) in alkaline condition followed by back-extraction into diluted acetic acid. Chromatography was carried out using a silica column (250 mmx4.6 mm, 5 microm) under isocratic elution with acetonitrile-40 mM aqueous sodium dihydrogen phosphate (25:75, v/v), pH 6. The limit of quantification (LOQ) was 15.6 ng/ml and the calibration curves were linear up to 2000 ng/ml. The mean absolute recoveries for metformin and internal standard using the present extraction procedure were 98 and 95%, respectively. The intra- and inter-day coefficient of variation and percent error values of the assay method were all less than 8.3%.

Adults with at least a 3-month history of heartburn were eligible for this randomized, double-blind, parallel group, multicentre dose-ranging study. Following a 1-week open-label run-in phase to document baseline heartburn frequency, subjects were randomized to receive treatment with one tablet of either ranitidine 75 mg (n = 491), ranitidine 25 mg (n = 504), or placebo (n = 494), to be taken as needed up to four times daily for 2 weeks for the relief of heartburn.

Sucralfate (Sc) suspension 6 g/day and ranitidine (Rn) tablets, 150 mg, were compared in 125 patients in a double-blind, multicenter, endoscopically controlled trial in the treatment of reflux esophagitis. Inclusion criteria were symptomatic reflux (number and severity of attacks) and endoscopic evidence of esophagitis (grades 1 to 4). Clinical assessments were performed on entry, and at 4 and at 8 weeks, and endoscopy was repeated at 8 weeks. Sc suspension and Rn placebo or Sc placebo and Rn tablets were taken on waking and immediately before retiring at night. Of the 125 patients, 27 were withdrawn because of default (Rn = 4; Sc = 14), noncompliance (Rn = 1; Sc = 2), or the development of congestive cardiac failure (Rn = 1), diarrhea (Rn = 1; Sc = 1), nausea (Sc = 1), constipation (Sc = 1), and hematemesis (Sc = 1). Analysis was performed on the remaining 98 patients, 43 of whom had been treated with Sc and 55 with Rn. Heartburn, acid regurgitation, epigastric pain, dysphagia, and chest pain were relieved in 34% vs 40%, 67% vs 72%, 71% vs 57%, and 86% vs 63% for Sc and Rn, respectively. There was no significant difference between the two groups. Endoscopic healing occurred in 47% of the Sc- and in 31% of the Rn-treated patients (chi 2 = 2.50), and healing or improvement was noted in 81% of the Sc- and 64% of the Rn-treated patients. This difference approached statistical significance (chi 2 = 3.73). There was no obvious endoscopic benefit in 8 of the 43 and 20 of the 55 patients in the groups treated with Sc and Rn, respectively. Although the findings with sucralfate and ranitidine in patients with reflux esophagitis completing the trial suggest a benefit of these agents, the absence of a placebo control group and the high default rates, particularly for those receiving sucralfate, preclude any firm conclusions as to relative or specific efficacy of these agents in this condition.

1. Quinpirole did not produce any effect in isolated uterus from oestrogenized rats even when it is contracted by KCl (37 mM). 2. Fenoldopam produced a relaxant effect on rat isolated uterus contracted by KCl which was not significantly modified by SCH 23390. 3. Reserpine decreased the effect of the lowest doses of fenoldopam. In reserpinized rats, propranolol (10(-9), 10(-8), 10(-7) M) antagonized the effect of the lowest doses of fenoldopam and neither SCH 23390, sulpiride nor ranitidine modified the effect of fenoldopam. 4. The results confirm our previous finding that DA1-receptors are not functional in our preparation. The effect of fenoldopam was partially due to a catecholamine-releasing action.

Effects of histamine and specific H1, H2 receptor agonists have been investigated on the isolated web skin melanophores of the frog, R. tigerina. Histamine, 2-methyl-histamine and 4-methyl-histamine all induced dose dependent dispersion in the frog melanophores. Reserpine treatment of the frog skin, either in vivo, or in vitro potentiated the dispersal response of the frog skin melanophores elicited by histamine. Histamine induced dispersal responses in the frog integumentary melanophores were partially blocked by mepyramine and ranitidine. Atropine failed to inhibit the dispersal response in any degree. Propranolol partially inhibited the dispersion of frog melanophores induced by histamine and 2-methyl-histamine. However, propranolol completely blocked the dispersal response of the buy zantac online mealnophores to 4-methyl-histamine. It is suggested that histamine induced dispersion in the frog skin melanophores in vitro is mediated partially through specific H1, H2 and beta adrenergic receptors.

The prevalence of low vitamin (B12, B6, erythrocyte folate, niacin) or high metabolite (homocysteine) levels among 75 patients were as follows: B12 <148 buy zantac online pmol/L in 5/75 (6.7%); B12 between 148 and 221 pmol/L in 26/75 (34.7%); B6 13.3 micromol/L in 31/75 (41.3%). There was no significant difference among residents grouped into marked (n = 44), mild (n = 14), or normal (n = 9) cognitive function when evaluating the effect of vitamin status. There were no significant differences in mean B12 and homocysteine levels between users and non-users of drug therapy (Losec, Zantac, or Axid). Compared to vitamin supplement non-users, supplemented residents had significantly higher mean B12 (p < 0.0001) and erythrocyte folate (p < 0.05) concentrations and significantly lower mean homocysteine (p < 0.01) levels; 229.1 versus 423.6 pmol/L for B12, 882.9 versus 1043.6 nmol/L for erythrocyte folate and 14.4 versus 12.0 micromol/L for homocysteine.

According to intention-to-treat analysis, H. pylori buy zantac online eradication rates were 96%, 91%, 20%, and 9% with regimens 1, 2, 3, and 4, respectively. Comparing regimens 1+2 and 3+4, the eradication rates with and without metronidazole were 93% and 14%, respectively (p < 0.0001). Metronidazole increased the occurrence of diarrhea and abdominal pain. Comparing regimens 1+3 with 2+4 ranitidine did not influence H. pylori eradication (58% with and 50% without ranitidine; p = 0.37) or ulcer healing (93% with and 90% without ranitidine; p = 0.72) significantly, but reduced the occurrence of pain (p < 0.01). Six months after treatment, three patients who were H. pylori negative at 4 wk had become positive. These three had all received metronidazole placebo. H. pylori status remained negative in the other 85 patients.

The three subgroups were well matched and 16 patients dropped out of the study for many reasons (six in the 4-day, five in the 7-day and five in the 10-day treatment regimens). Intention-to-treat cure rates were 60%, 84% and 85%, and the per-protocol rates 67%, 92% and 94% in the 4-day, 7-day and 10-day treatment regimens, respectively. There was a significant difference, P = 0.003-0.006 on intention-to-treat and P = 0.001-0. 002 on per protocol analysis between the 4-day and the 7-day and the 4-day and the 10-day periods, respectively. The 7-day and 10-day periods did not differ from each other. Side-effects buy zantac online were reported in 9%, 14% and 20% of the 4-, 7- and 10-day regimens. They led to stopping treatment in four cases (one in the 7-day and three in the 10-day period). There was no statistical difference among them.

The conditioning regimen preceding hematopoietic stem cell transplantation (HSCT) causes a rapid decrease in the platelet count and signs of disseminated intravascular coagulation, possibly indicating platelet activation. As impacts during the conditioning regimen may predict later transplantation-associated complications, we investigated changes in platelet membrane glycoproteins (GP) and the liberation of microparticles. Platelet receptors and granules of 49 patients undergoing HSCT were evaluated by flow cytometric analysis before and after the different phases of the conditioning regimen [chemotherapy, total body irradiation (TBI), therapy with antithymocyte globulin (ATG)] and final transplantation. Following chemotherapy a high surface expression of CD62P, a low mepacrine staining, and a reduced surface expression of CD42b (part of the GP Ib/V/IX complex) were found, indicating an irreversible activation of platelets. In addition, elevated levels of circulating microparticles were observed, which may reinforce the thrombosis risk in these patients. Treatment with ATG leads to an elevated surface expression of PAC-1 epitopes, which are neoepitopes appearing after activation of GP IIb/IIIa. However, a significant degranulation was not detectable, which may be the consequence of inhibitory influences on platelets during ATG-induced cytokine release syndrome. TBI and transplantation itself had no influence on platelets. This study was able to demonstrate activating effects buy zantac online on platelets by certain phases of the conditioning regimen in patients receiving HSCT. Chemotherapy, in particular, leads to a strong and irreversible platelet activation and a generation of microparticles, which may cause an increased thrombosis risk. Our findings underline the impact of platelets on the pathogenesis of hemostatic complications during HSCT.

Among the 52 patients given buy zantac online antibiotics, H. pylori was eradicated in 46, as compared with 1 of the 52 given placebo (89 percent vs. 2 percent, P < 0.001). After six weeks, the ulcers were healed in 48 patients given antibiotics and 39 given placebo (92 percent vs. 75 percent, P = 0.011). Side effects, mainly diarrhea, occurred in 15 percent of the patients given antibiotics. Among the patients followed up for 12 months, duodenal ulcers recurred in 4 of 50 patients given antibiotics and 42 of 49 given placebo (8 percent vs. 86 percent, P < 0.001). Ulcers recurred in 1 of 46 patients in whom H. pylori had been eradicated, as compared with 45 of 53 in whom H. pylori persisted (2 percent vs. 85 percent, P < 0.001).

In a Swedish double-blind multicenter study involving 143 patients, the new proton pump inhibitor omeprazole (30 mg taken as a single morning dose) was compared with ranitidine (400 mg b.i.d.). Clinical assessment and laboratory investigations were carried out at 2 and 4 weeks, and again at 6 weeks if patients had not healed earlier. Endoscopy was repeated at two-weekly intervals until the ulcer was healed. The patients in the two treatment groups were well matched prior to treatment. There was a higher ulcer healing rate in the omeprazole group (70%) than in the ranitidine group (55%) after two weeks of treatment. This difference reached statistical significance in 128 patients adhering to the protocol as shown by a logit model analysis with drug, ulcer size and smoking as the prognostic factors (p = 0.04). There were no major differences between the two treatment groups in terms of symptomatic relief. Both drugs were generally well tolerated, and the number of adverse events in the two treatment groups Vasotec Maximum Dose were similar. After healing, 127 patients entered a follow-up study, with endoscopy either after 6 months or on recurrence of symptoms. There was no significant difference between the two treatment groups, with the relapse frequency within 6 months being 39% in the omeprazole group and 47% in the ranitidine group. These results, with a 15 percentage points higher ulcer healing rate for omeprazole as compared with H2-receptor antagonists after two weeks, are in accordance with results reported in other studies.

In this study, histamine (HA) receptors in chick cerebral cortex were characterized using two approaches: (1) analysis of the effects of HA-ergic drugs on the cAMP-generating system, and (2) radioreceptor binding of [(3) H]tiotidine, a selective H(2) antagonist. HA was a weak activator of adenylyl cyclase in a crude membrane preparation of chick cerebrum. On the other hand, HA (0.1-1000 microm) potently and concentration dependently stimulated cAMP production in [(3) H]adenine pre-labelled slices of chick cerebral cortex, displaying an EC(50) value (concentration that produces 50% of maximum response) of 2.65 microm. The effect of HA was mimicked by agonists of HA receptors with the following rank order of potency: HA >or= 4-methylHA (H(2)) >or= N Glucophage 500mg Cost alpha,N alpha-dimethylHA (H(3) > H(2) = H(1)) > 2-methylHA (H(1)) > 2-thiazolylethylamine (H(1)) >or= R alpha-methylHA (H(3)) > amthamine, dimaprit (H(2)), immepip (H(3), H(4)). The HA-evoked increase in cAMP production in chick cerebral cortex was antagonized by selective H(2) receptor blockers (aminopotentidine >or= tiotidine > ranitidine > zolantidine), and not significantly affected by mepyramine and thioperamide, selective H(1) and H(3) /H(4) receptor blockers, respectively. A detailed analysis of the antagonistic action of aminopotentidine (vs. HA) revealed a non-competitive mode of action. The binding of [(3) H]tiotidine to chick cortical membranes was rapid, stable and reversible. Saturation analysis resulted in a linear Scatchard plot, suggesting binding to a single class of receptor binding site with high affinity [equilibrium dissociation constant (K (d)) = 4.42 nm] and high capacity [maximum number of binding sites (B (max) ) = 362 fmol/mg protein]. The relative rank order of HA-ergic drugs to inhibit [(3) H]tiotidine binding to chick cerebrum was: antagonists - tiotidine > aminopotentidine = ranitidine >or= zolantadine > thioperamide - triprolidine; agonists - HA >or= 4-methylHA > 2-methylHA >or=R alpha-methylHA - dimaprit. In conclusion, chick cerebral cortex contains H(2) -like HA receptors that are linked to the cAMP-generating system and are labelled with [(3) H]tiotidine. The pharmacological profile of these receptors is different from that described for their mammalian counterpart. It is suggested that the studied receptors represent either an avian-specific H(2) -like HA receptors or a novel subtype of HA receptors.

Ambulatory oesophageal pH, oesophageal manometry and fasting serum gastrin concentrations were carried out on 28 patients with reflux oesophagitis, before and during treatment with ranitidine 300 mg bd. Fourteen patients healed endoscopically at six weeks (group A) and 14 had residual oesophagitis (group B). Group Oxytrol 10 Mg A were characterised by a lower serum gastrin concentration before treatment (4.52 pmol/l; 2.4-10: mean and range) than group B (11.1 pmol/l; 3.5-21: p less than 0.05) and showed a marked reduction in acid reflux on treatment to near normal values. Mean per cent time below pH4 fell from 14.9 to 4.2 in group A (p less than 0.05) but was not affected in group B (14.2-15.6, not significant). Abnormal oesophageal motility was found in 13 patients from each group. This did not inhibit the response to ranitidine, and was not improved by healing of oesophagitis.

Sucralfate has been evaluated in reflux esophagitis. The rationale for its effectiveness is based on its protective adherence to denuded mucosal surfaces and its bile salt binding properties. According to Weiss et al (5), healing occurred in 72% and improvement in 14% of sucralfate treated patients, compared respectively to 40% and 20% receiving placebo (p less than 0.05). According to Laitinen et al (6) esophagitis healed in 53% of patients receiving sucralfate, against 34% of an Aricept 10 Pill alginate/antacid-treated group. Symptoms disappeared, or improved in almost 70% of both groups. Hameeteman et al (7) found improvement of esophagitis in 53% and healing in 31% after sucralfate, compared with 67% and 14% respectively after cimetidine. Symptomatic improvement was good and comparable in both groups. Simon et al (8) found endoscopic healing in 64% and improvement in 27% of sucralfate-healed patients, compared with 68% and 21% respectively after ranitidine. Symptom relief and antacid consumption was comparable in both groups. Sucralfate appears to be a safe and efficacious locally active mucosal protecting agent for the treatment of reflux esophagitis. Its efficacy is comparable to that of H2-receptor blockers.

The eradication rate of Helicobacter pylori was of 76.4% on an 'intention-to treat' and 82.6% on 'per protocol' analysis. In patients with successful eradication, the standardized and transformed quality of life score increased after 6-8 weeks from 56.2 + 9.8 (95% confidence interval: 53.9-58.4) to 70.8 + 10.7 (68.3-73.5) (p = 0.0001) and to 75.3 + 9.3 (73.2-77.5) at 1 year (p = 0.005). In the patients with failed eradication, the quality of life has not been changed significantly (p = 0.76). The quality of life scores increased in Helicobacter pylori negative cases from 60.0 + 9.8 (58.0-62.0) to 73.3 + 9.6 (71.3 + 75.4) after 6 weeks (p = 0.0001) and to 76.5 + 8.5 (74.5 - 78.4) at 1 year (p = 0.56). The effect size was large in both groups and there were no differences between the treatment arms either at 6-8 weeks (p = 0.11) or after 1 year (p = 0.43).
