celebrex 75 mg

Clinical and animal studies indicate a role for cyclooxygenase-2 (COX-2) and the epidermal growth factor receptor (EGFR) in the development and progression of intestinal polyps and cancers. Although this combination of enzyme inhibition has shown synergy in intestinal polyp and tumor models, the exact mechanism for these effects remains undefined. Therefore, we sought to define the molecular mechanisms through which this process occurs. We observed a significant reduction in the number and size of small intestinal polyps in APC(min+/-) mice treated with either celecoxib (a selective COX-2 inhibitor) or erlotinib (Tarceva, an EGFR inhibitor). However, in combination, there was an overall prevention in the formation of polyps by over 96%. Furthermore, we observed a 70% reduction of colorectal xenograft tumors in mice treated with the combination and microarray analysis revealed genes involved in cell cycle progression were negatively regulated. Although we did not observe significant changes in mRNAs of genes with known apoptotic function, there was a significant increase of apoptosis in tumors from animals treated with the combination. The inhibition of EGFR also induced the down-regulation of COX-2 and further inhibited prostaglandin E2 formation. We observed similar effects on the prevention of intestinal adenomas and reduction of xenograft tumor volume when nonselective COX inhibitors were used in combination with erlotinib. Together, these findings suggest that the inhibition of both COX-2 and EGFR may provide a better therapeutic strategy than either single agent through a combination of decreased cellular proliferation and prostaglandin signaling as well as increased apoptosis.

The primary purpose of this study was to process partially hydrolyzed PVOH grades (degree of hydroxylation (DH): 33-88%) via HME and to evaluate them as carrier for oral immediate release dosage forms in order to improve the release rate of poorly water soluble drugs (i.e., HCT and CEL) via the formulation of solid dispersions. PVOH grades (DH >70%) were able to solubilize HCT and CEL up to 15%, but required higher extrusion temperature, due to the crystalline nature of PVOH. The highest drug release rate was observed from hot-melt extruded PVOH samples with a high DH. While drug release from extrudates consisting of PVOH with a low DH was affected by ionic strength, there was no influence of pH and ionic strength on HCT release from PVOH samples with a higher DH. However, PVOH (DH >70%) required higher extrusion temperatures, which could hamper its application for thermosensitive drugs. Therefore, the secondary purpose was to investigate the effect of sorbitol, a water-soluble plasticizer, on the thermal properties of hot-melt extruded PVOH (DH >70%). The melting of PVOH/sorbitol mixture was required to establish molecular interactions between PVOH and sorbitol. These molecular interactions were reflected in the HME behavior: whereas an extrusion temperature of 180 °C was necessary to process physical mixtures of PVOH (DH >70%) and sorbitol, only 140 °C was necessary during re-extrusion (after quench cooling and cryomilling) of the PVOH/sorbitol mixture. In addition, the in vitro and in vivo dug release of plasticized PVOH was examined; whereas the CEL/PVO/sorbitol system was able to maintain supersaturation during in vitro dissolution (0.1N HCl) compared to Celebrex(®), the in vivo pharmacokinetic parameters (AUC0-24h, Cmax and Tmax) were highly comparable.

Although cyclooxygenase (COX)-2 inhibitors (coxibs) are effective in controlling inflammation, pain, and tumorigenesis, their use is limited by the recent revelation of increased adverse cardiovascular events. The mechanistic basis of this side effect is not well understood. We show that the metabolism of endocannabinoids by the endothelial cell COX-2 coupled to the prostacyclin (PGI(2)) synthase (PGIS) activates the nuclear receptor peroxisomal proliferator-activated receptor (PPAR) delta, which negatively regulates the expression of tissue factor (TF), the primary initiator of blood coagulation. Coxibs suppress PPARdelta activity and induce TF expression in vascular endothelium and elevate circulating TF activity in vivo. Importantly, PPARdelta agonists suppress coxib-induced TF expression and decrease circulating TF activity. We provide evidence that COX-2-dependent attenuation of TF expression is abrogated by coxibs, which may explain the prothrombotic side-effects for this class of drugs. Furthermore, PPARdelta agonists may be used therapeutically to suppress coxib-induced cardiovascular side effects.

In this prospective, double-blind, placebo-controlled study, 105 patients were randomized into three groups: Group I, in which patients received infiltration with ropivacaine, ketorolac, and adrenaline followed by continuous infusion of 0.2% ropivacaine at 5 mL/hr; Group II, in which patients received infiltration with ropivacaine, ketorolac, and adrenaline followed by continuous infusion of saline solution at 5 mL/hr; and Group III, in which patients received infiltration with saline solution followed by continuous infusion of saline solution at 5 mL/hr.All patients received celecoxib, pregabalin, and acetaminophen perioperatively and patient-controlled analgesia; surgery was performed under general anesthesia. Before wound closure, the tissues and periarticular space were infiltrated with ropivacaine, ketorolac, and adrenaline or saline solution and a fenestrated catheter was placed. The catheter was attached to a pump prefilled with either 0.2% ropivacaine or saline solution set to infuse at 5 mL/hr.The primary outcome measure was postoperative opioid consumption and the secondary outcome measures were pain scores, adverse side effects, and patient satisfaction.

Thirteen patients were recruited before trial closure due to external safety concerns regarding celecoxib. Median follow up was 17 months (95% CI 9 - >39). The highest administered dose was 400 mg bd (n=4) with one dose-limiting toxicity at this level: grade 3 rash. Five (38%) and 8(62%) patients had grade 3 non-haematological and haematological toxicities respectively. No grade 4 toxicities occurred. Radiological response rate was 54% (n=7: all CR). Six patients had resection with one pathological CR. Median progression-free and overall survival were 8.8 (95% CI 5.1 - >24.8) and 19.6 months (95% CI 7.3 - >39) respectively.

A number of case reports and well-controlled clinical trials were identified that provided evidence of the relatively well known drug-drug interactions between prescription/OTC NSAIDs and alcohol, antihypertensive drugs, high-dose methotrexate, and lithium, as well as between frequently prescribed narcotics and other central nervous system depressants. In contrast, the ability of recent alcohol ingestion to exacerbate the hepatotoxic potential of therapeutic doses of acetaminophen is not supported by either case reports or clinical research. Use of ibuprofen according to OTC guidelines in patients taking cardioprotective doses of aspirin does not appear to interfere with aspirin's antiplatelet activity, whereas chronic prescription use of ibuprofen and other NSAIDs may interfere. Low-dose aspirin intake appears to abolish the gastroprotective effects of cyclooxygenase-2-selective inhibitors, including celecoxib. There is evidence of other less well known and potentially clinically significant drug-drug interactions, including the ability of selective serotonin reuptake inhibitors to inhibit the analgesic activity of tramadol and codeine through inhibition of their metabolic activation, to induce serotonin syndrome when used chronically in the presence of high doses of tramadol through synergistic serotonergic action, and to increase the potential for gastrointestinal bleeding associated with NSAID therapy through additive or supra-additive antiplatelet activity.

The chemopreventive efficacy of NSAIDs against colorectal cancer has been established. Also, NSAIDs may decrease the incidence of carcinomas of the esophagus, stomach, breast, lung, prostate, urinary bladder and ovary. The clinical use of these agents is limited to patients with familial adenomatous polyposis (FAP), which may benefit from chemopreventive treatment with sulindac or the selective COX-2 inhibitor celecoxib. The mechanism of chemoprevention by NSDAIDs is still a matter of debate. COX-2 inhibition explains at least part of the observed effects, however, other targets have been proposed. The effect of NSAIDs is incomplete and molecular mechanisms related to resistance need to be studied. Also, more effective chemopreventive regimens are needed; combination therapy appears attractive, potentially increasing efficacy and decreasing toxicity. This review discusses molecular and clinical aspects of chemoprevention of the adenomacarcinoma sequence with NSAIDs or COX-2 inhibitors.

A total of 11 women completed the study (Group 1, n=7; Group 2, n=4). No demographic differences were found between groups [age, race, body mass index (BMI), control cycle length]. A comparison of the control and active drug cycles for all participants demonstrated a trend toward a longer menstrual cycle with active drug exposure [control, 27.2 days (SD, 2.4); study drug, 28.5 days (SD, 2.5), p=.09]. Five women had a delay in the rise of their luteal phase P levels, two women had lower peak P levels and two women had no elevation of luteal phase P levels during active drug cycle as compared to placebo cycle.

Interruption of the cell cycle is accompanied by changes in several related molecules that result in the activation of apoptosis. The present study was performed to verify the apoptotic effects of sequential treatment with bortezomib and celecoxib in TC-1 cells expressing the human papillomavirus (HPV) E6 and E7 proteins. In TC-1 cells sequentially treated with bortezomib and celecoxib, apoptosis was induced through decreased expression of signal transducer and activator of transcription-3 (STAT3), cyclin D1 and cyclin-dependent kinase (CDK) 2, which are major regulators of the G0/G1 cell cycle checkpoint. In addition, increased levels of p21, CHOP, BiP and p-p38 MAPK were identified in these cells. The treatment-induced apoptosis was effectively inhibited by treatment with SB203580, an inhibitor of p-p38. Moreover, the growth of tumors sequentially treated with bortezomib and celecoxib was retarded compared to the growth of tumors exposed to a single treatment with either bortezomib or celecoxib in vivo. We demonstrated that sequential treatment with bortezomib and celecoxib induced apoptosis via p-p38-mediated G0/G1 cell cycle arrest and endoplasmic reticulum (ER) stress. Sequential treatment with these two drugs could therefore be a useful therapy for cervical cancer.

The combination of the two drugs administered for 60 consecutive days resulted in a significantly longer time to tumor regrowth (p < 0.011) and longer tumor doubling time (p < 0.013) in both xenografts than for the lower-dose CPT-11 therapy alone, without substantial side effects in mice. In particular, five of six TNB9 tumors treated with the combination of the two drugs showed no regrowth even 120 or 150 days after the initiation of therapy. The combined treatment suppressed the induction of autophagy leading to apoptosis in TNB9 tumors, and induced autophagy to enhance the antitumor effect in TS-N-2nu tumors.

Oxaliplatin (OXA) is the common and extremely potent anti-advanced colorectal cancer chemotherapeutic. Accumulating evidence reveals that OXA evokes mechanical and cold hypersensitivity. However, the mechanism underlying these bothersome and dose-limiting adverse effects is poorly understood. It is well known that cyclooxygenase-2 (COX-2) as well as phosphoinositide 3-kinase (PI3K)/Akt signaling mediate the neuropathic pain. But it is still unclear whether COX-2 or PI3K/Akt signaling participates in the regulation of OXA-induced hypersensitivity, as well as the linkage between COX-2 and PI3K/Akt signaling in mediating OXA-induced hypersensitivity. In this paper, we investigated the anti-nociceptive effect of celecoxib, an inhibitor of COX-2, on the OXA-induced neuropathic pain. We found that OXA increased the expression of cyclooxygenase-2 (COX-2) and Akt2 in the lumbar 4-5 (L4-5) dorsal root ganglion (DRG). And the administration of celecoxib alleviates the OXA-induced hypersensitivity and suppresses the COX-2 and PI3K/Akt2 signaling. Our findings showed that COX-2 and PI3K/Akt2 signaling in DRG contributed to the OXA-induced neuropathic pain. In addition, celecoxib enhanced the OXA-induced mortality of the human colon cancer cell line HCT-116. Thus, celecoxib might play a dual role in colorectal cancer treatment: alleviating OXA-induced neuropathic pain and facilitating the anti-tumor effects of OXA through their synergistic role.

As it has been demonstrated in a previous study, both cyclooxygenases (COXs) and nitric oxide synthases (NOSs) participate in the mechanism of acetaminophen (ACETA) action. Results obtained in this study indicate that intrathecal (it) or intracerebroventricular (icv) pretreatment with LG-nitro-L-arginine (L-NO-Arg), a non-selective inhibitor of NOS activity, as well as with 7-nitroindazole (7-NI), a selective nNOS inhibitor, potentiated the antinociceptive activity of subceiling doses of ACETA, but were without effect on the action of supramaximal doses in Randall-Selitto test. Similar effect of L-NO-Arg and 7-NI it was observed in writhing test, whereas L-NO-Arg icv or L-NIL it did not influence the action of ACETA in this model. Indomethacin (IND), an inhibitor preferentially acting on COX-1, as well as nimesulide (NIM) and celecoxib (CECOX), i.e. preferential and selective inhibitor of COX-2, respectively, administered icv almost completely blocked the antinociceptive effect of ACETA in Randall-Selitto method. On the other hand, pretreatment with NSAIDs it initially increased and then attenuated the ACETA antinociception. Yohimbine (YOH), an alpha2-adrenergic receptor antagonist, did not modify the antinociceptive action of ACETA administered alone. However, YOH decreased the nociceptive threshold increased by simultaneously administered IND and ACETA, NIM and ACETA, as well as CECOX and ACETA in Randall-Selitto model. In contrast to the peripheral (sc) application, IND administered centrally (icv or it) did not modify the ACETA antinociception in writhing test. Neither NIM nor CECOX administered sc, it or icv changed the ACETA antinociception in this model. Possible mechanisms and sites of antinociceptive effects of ACETA are discussed.

Exposure to CAL-101 and celecoxib significantly increased apoptosis, which was accompanied by the inactivation of AKT, Ras homolog gene family, member A (RHOA), Rho-associated coiled-coil containing protein kinase 1 (ROCK1), and ROCK2 as well as up-regulation of Phosphatase and tensin homolog (PTEN). Co-treatment with CAL-101 and celecoxib triggered the ER stress response and the down-regulation of BCL2 and BCL-XL. SB203580, SP600125, and salubrinal effectively inhibited apoptosis and attenuated expression of phosphorylated protein kinase RNA-like endoplasmic reticulum kinase (PERK) and CCAAT-enhancer-binding protein homologous protein (CHOP). Levels of apoptosis signal-regulating kinase 1 (ASK1) were also increased after treatment with CAL-101 and celecoxib.

The cohort included 336,906 persons, with 989,826 person-years of follow-up, and 4354 stroke hospitalizations. There were 4.51 strokes per 1000 person years in the nonuse group, 5.15 strokes per 1000 person years (adjusted HR 1.28, 95% CI 1.06, 1.53) with rofecoxib use, and 5.95 strokes per 1000 person years (adjusted HR 1.41, 95% CI 1.04, 1.91) with valdecoxib use. New use of rofecoxib and valdecoxib led to 6.06 (adjusted HR 1.46 95% CI 1.08, 1.98) and 6.19 (adjusted HR 1.39, 95% CI 0.74, 2.59) strokes per 1000 person years respectively. No other NSAID significantly increased the risk of incident stroke.

celebrex reviews 2015 2017-01-26

Recently, our laboratory has proposed the avulsion of rat brachial plexus as a new and reliable model for the study of neuropathic pain. In this model, the neuropathy can be detected even at distant sites from the buy celebrex online injury, both in ipsilateral and contralateral hindpaws. The purpose of this study was to pharmacologically characterise this behavioural model of persistent peripheral neuropathic pain by assessing the effects of several analgesic drugs currently used in clinical practice. For this purpose, the effects of these drugs on the mechanical and cold allodynia were analysed 20-40 days after rat brachial plexus avulsion. Injection of saline, administered by the same route as the other drugs, did not significantly affect the nociceptive threshold either in sham-operated or in neuropathic rats. However, administration of the opioid analgesic morphine (5 mg/kg, s.c.), the alpha2 adrenoceptor agonist clonidine (300 microg/kg, i.p.), the NMDA receptor antagonist ketamine (25 mg/kg, i.p.) or the anticonvulsant drug gabapentin (70 mg/kg, p.o.) consistently reduced both mechanical and cold allodynia following avulsion of rat brachial plexus. The administration of the selective COX-2 inhibitor celecoxib (10 mg/kg, p.o.) blocked mechanical allodynia, but not cold allodynia, whereas the sodium channel blocker lidocaine (40 mg/kg, i.p.) attenuated only cold allodynia. The non-steroidal anti-inflammatory drug diclofenac (100 mg/kg, i.p.), the steroidal anti-inflammatory dexamethasone (1.5 mg/kg, i.p.) and the antidepressant imipramine (10 mg/kg, i.p.) all failed to significantly attenuate both mechanical and cold allodynia in the rats following avulsion of brachial plexus. These findings suggest that avulsion-associated mechanical and cold allodynia, two classic signs of persistent neuropathic pain, were consistently prevented by several analgesics currently available in clinical practice, namely morphine, clonidine, ketamine and gabapentin, and to a lesser extent by celecoxib and lidocaine. Therefore, this new proposed model of persistent nociception seems to be suitable for the study of the underlying mechanisms involved in neuropathic pain and for the identification of potential clinically relevant drugs to treat this aspect of peripheral neuropathy.

A biphasic in vitro test method was used to examine release profiles of a poorly soluble model drug, celecoxib (CEB), from its immediate release formulations. Three formulations of CEB were investigated in this study, including a commercial Celebrex capsule, a solution formulation (containing cosolvent and surfactant) and a supersaturatable self-emulsifying drug delivery system (S-SEDDS). The biphasic test system consisted of an aqueous buffer and a water-immiscible organic solvent (e.g., octanol) with the use of both USP II and IV apparatuses. The aqueous phase provided a nonsink dissolution medium for CEB, while the octanol phase acted as a sink for CEB partitioning. For comparison, CEB concentration-time profiles of these formulations in the aqueous medium under either a sink condition or a nonsink condition were also explored. CEB release profiles of these formulations observed in the aqueous medium from either the sink condition test, the nonsink condition test, or the biphasic test have little relevance to the pharmacokinetic observations (e.g., AUC, C(max)) in human subjects. In contrast, a rank order correlation among the three CEB formulations is obtained between the in vitro AUC values of CEB from the octanol phase up to t = 2 h and the in vivo mean AUC (or C(max)) values. As the biphasic test permits a rapid removal of drug from the buy celebrex online aqueous phase by partitioning into the organic phase, the amount of drug in the organic phase represents the amount of drug accumulated in systemic circulation in vivo. This hypothesis provides the scientific rationale for the rank order relationship among these CEB formulations between their CEB concentrations in the organic phase and the relative AUC or C(max). In addition, the biphasic test method permits differentiation and discrimination of key attributes among the three different CEB formulations. This work demonstrates that the biphasic in vitro test method appears to be useful as a tool in evaluating performance of formulations of poorly water-soluble drugs and to provide potential for establishing an in vitro-in vivo relationship.

Formation of reactive oxygen species and mitochondrial/lysosomal damages were significantly inhibited by both acetylsalicylic acid and celecoxib in hepatocytes of all pain- suffering animals. Nonetheless, celecoxib's tendency to raise caspase 3 activities, suggested that it accelerates the apoptosis in hepatocytes of pain-suffering animals. Our results showed that the pain per se, could initiate some harmful signals that affect other cells other than neurons; these malicious signals could be magnified by use of some analgesics particularly buy celebrex online selective cyclo-oxygenase inhibitors.

Poor aqueous solubility and bioavailability of drugs are one of the important factors affecting the absorption of drugs and consequently their therapeutic effectiveness. Celecoxib is a widely used anti-inflammatory agent, with special use in rheumatoid arthritis. It belongs to biopharmaceutical classification system (BCS) class II drug with low solubility and high permeability. The present study was aimed to prepare and characterize the microcrystals of celecoxib, employing in situ micronization technique by rapid solvent change approach to enhance the solubility and dissolution rate and to optimize the solvent and anti-solvent ratio (v/v) using hydrophilic stabilizers such as guar gum, maltodextrin and PVP K30. The prepared formulations were evaluated for percentage crystal yield, mean particle size, drug content and in vitro dissolution studies. Amongst the formulations prepared (F1-F9), F6 formulation containing maltodextrin as stabilizing agent at 0.1% w/v concentration with 1:6 ratio of solvent to anti-solvent (v/v) respectively was considered as optimized formulation in which percentage drug release was buy celebrex online found to be 89.33% within 60 minutes in comparison with that of the pure drug dissolution of 30.26% only within 60 minutes. Characterization studies like SEM, DSC and XRD indicate the solubility enhancement of celecoxib microcrystals due to decrease in particle size when compared to that of pure drug. FT-IR spectroscopy studies revealed that there is no chemical interaction between the drug and stabilizer and crystalline habit modification occurs in the microcrystals without any polymorphic changes.

Anti-manic effects were evaluated in two trials, one of adjunctive n-acetyl cysteine (NAC), one of omega-3 fatty acids (O3FA), and significant improvements only emerged for NAC. Celecoxib had a rapid but short-lived antidepressant effect. Despite limited effects of O3FA on symptoms, imaging data demonstrated alterations in neuronal functioning that might have longer-term therapeutic effects. Evidence was strongest buy celebrex online for adjunctive NAC in bipolar depression though conclusions are limited by small sample sizes.

Celecoxib is a specific inhibitor of cyclooxygenase 2 (COX2). While it has been used for the treatment of chronic inflammatory conditions, including rheumatoid arthritis, its detailed anti-inflammatory mechanism has not been clarified. Here, we found that Celecoxib potently inhibited TNFalpha-induced transcriptional activity and DNA binding activity of NF-kappaB; however, Celecoxib had no effect on TNFalpha-induced IKK activation and degradation of IkappaBalpha and IkappaBbeta, suggesting that it inhibited NF-kappaB activation via suppressing downstream of IKK activation and IkappaBs degradation. Interestingly, it buy celebrex online was also found that Celecoxib abrogated TNFalpha-induced nuclear accumulation of the NF-kappaB p65 subunit. As a result, TNFalpha-induced expression of inflammatory cytokines, CXCL1/KC and CCL2/MCP-1, was clearly inhibited by Celecoxib. On the other hand, Celecoxib had no effect on the TNFalpha-induced nuclear translocation of c-jun and activation of ERK, JNK, p38 and Akt. Taken together, these data indicate that Celecoxib specifically inhibits TNFalpha-induced NF-kappaB activation at the level of its nuclear translocation. This negative regulation of NF-kappaB activation by Celecoxib might be an important mechanism leading to its anti-inflammatory activity.

Totally 93 patients completed the followed-up study. The JOA scores were improved after treatment, at 6 and buy celebrex online 12 months of followed-ups (P < 0.05, P < 0.01). The JOA score at 6 months of followed-ups was superior in the treatment group to that of the control group (P < 0.05). Five patients (accounting for 10.6%) suffered from FBSS in the treatment group, while 9 (accounting for 19.6%) suffered from FBSS in the control group. The treatment group was superior to the control group (P < 0.05). The TNFalpha level was improved after treatment in the two groups. Of them, the improvement of TNF-alpha in the treatment group was better than that of the control group (P < 0.05).

It has been observed that several cyclooxygenase-2 (COX-2) inhibitory chemicals might inhibit proliferation of various cancer cells through COX-2-independent action. We also identified that celecoxib more selectively kills cell lines derived from head and neck squamous cell carcinoma (HNSCC) than its non-cancerous counterparts, irrespective of COX-2 expression. Herein, we investigated whether the regulation of mitogen-activated protein kinases activity might be one of the main mechanisms related to a conspicuous COX- Avapro Generic Alternative 2-independent tumor-killing effect of celecoxib in HNSCC cell lines. We assessed the effect of celecoxib on extracellular signal-regulated kinase (ERK), p38, and c-Jun NH2-terminal kinase activity by a transcription factor activation assay then evaluated, if these factors might be involved in the COX-2-independent tumor-killing effect of celecoxib by blocking their activity. We found that the blocking activation of ERK and/or p38 could reverse the celecoxib-induced cell growth inhibition by 50-80% in HNSCC cell lines, but it was not tested in cancer cells of other types. In conclusion, our study suggests that most COX-2-independent tumor-killing action of celecoxib is mediated by the upregulation of ERK and/or p38 activity in HNSCC cells. These results encourage investigation on the underlying mechanisms and detailed outcomes of mitogen-activated protein kinases activation by celecoxib more concisely, for using its excellent tumor-killing effect more safely in the clinical field of cancer treatment.
