/BOXED WARNING/ WARNING: RISK OF SERIOUS GASTROINTESTINAL EVENTS. Gastrointestinal Bleeding, Ulceration, and Perforation: Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events.

A subpopulation of patients with asthma may have aspirin-sensitive asthma which may include chronic rhinosinusitis complicated by nasal polyps; severe, potentially fatal bronchospasm; and/or intolerance to aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs). Because cross-reactivity between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, celebrex is contraindicated in patients with this form of aspirin sensitivity. When celebrex is used in patients with preexisting asthma (without known aspirin sensitivity), monitor patients for changes in the signs and symptoms of asthma.

Celecoxib is indicated for symptomatic treatment of adult osteoarthritis (OA) and adult rheumatoid arthritis (RA). Celecoxib is not a substitute for aspirin for cardiovascular event prophylaxis. It may be also be used to treat acute pain from various sources, juvenile rheumatoid arthritis in children over 2, ankylosing spondylitis, and primary dysmenorrhea. Celecoxib, in combination with [tramadol], is indicated for the management of acute pain in adults severe enough to require an opioid analgesic and in whom alternative treatments are inadequate.
Onsenal is indicated for the reduction of the number of adenomatous intestinal polyps in familial adenomatous polyposis (FAP), as an adjunct to surgery and further endoscopic surveillance (see section 4. 4).
The effect of Onsenal-induced reduction of polyp burden on the risk of intestinal cancer has not been demonstrated (see sections 4. 4 and 5. 1)
Celecoxib inhibits cyclooxygenase 2 (COX-2) enzyme, reducing pain and inflammation. It is important to note that though the risk of bleeding with celecoxib is lower than with certain other NSAIDS, it exists nonetheless and caution must be observed when it is administered to those with a high risk of gastrointestinal bleeding. **A note on the risk of cardiovascular events** Significant concerns regarding the safety of COX-2 selective NSAIDs emerged in the early 2000s. [Rofecoxib], another member of the COX-2 inhibitor drug class, also known as Vioxx, was withdrawn from the market due to prothrombotic cardiovascular risks. Following an FDA Advisory Committee meeting in 2005, in which data from large clinical outcome trials were evaluated, the FDA concluded that the risk for cardiovascular thrombotic events for both COX-2 selective NSAIDs and nonselective NSAIDs was evident. It was determined that the benefits of celecoxib treatment, however, outweighed the risks. Postmarketing cardiovascular outcomes trial (PRECISION) revealed that the lowest possible dose of celecoxib was similar in cardiovascular safety to moderate strength doses of both naproxen and ibuprofen. Patients who had previous cardiovascular events including acute MI, coronary revascularization, or coronary stent insertion were not evaluated in the trial. It is not advisable to administer NSAIDS to these groups of patients.
Cyclooxygenase 2 Inhibitors
A subclass of cyclooxygenase inhibitors with specificity for CYCLOOXYGENASE-2. (See all compounds classified as Cyclooxygenase 2 Inhibitors.)
Anti-Inflammatory Agents, Non-Steroidal
Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects. (See all compounds classified as Anti-Inflammatory Agents, Non-Steroidal.)

Absorption
Celecoxib is absorbed rapidly in the gastrointestinal tract. When a single oral dose of 200 mg was given to healthy research subjects, the peak plasma levels of celecoxib occurred within 3 hours. The Cmax is 705 ng/mL. When multiple doses are given, steady-state concentrations are reached on or before day 5. When taken with a high-fat meal, peak plasma levels are delayed for about 1 to 2 hours with an increase in total absorption (AUC) of 10% to 20%. The AUC of celecoxib has been shown to be significantly lower in patients with chronic renal impairment. A meta-analysis of pharmacokinetic studies has suggested an approximately 40% higher AUC (area under the curve) of celecoxib in black patients compared to Caucasians for unknown reasons.
Route of Elimination
Celecoxib is primarily eliminated by hepatic metabolism with small amounts (<3%) of the unchanged drug found in both the urine and feces. About 57% of an oral dose of celecoxib is excreted in the feces and 27% is found to be excreted into the urine in the form of metabolites. The main metabolite in urine and feces is identified as the carboxylic acid metabolite (73%). The amount of glucuronide in the urine is reported to be low.
Volume of Distribution
The apparent volume of distribution of celecoxib at steady state (Vss/F) is about 429 L, which suggests wide distribution into various tissues. Celecoxib is not preferentially bound to red blood cells. Another resource reports a volume of distribution of 455 166L.
Clearance
Apparent clearance (CL/F), single oral 200 mg dose, healthy subjects = 27.7 L/hr. Clearance may be decreased by about 47% in patients with chronic renal insufficiency, according to a pharmacokinetic study. Studies have not been performed in patients with severe renal impairment.
/MILK/ Limited data from 3 published reports that included a total of 12 breastfeeding women showed low levels of Celebrex in breast milk. The calculated average daily infant dose was 10-40 ug/kg/day, less than 1% of the weight-based therapeutic dose for a two-year old-child.

/MILK/ The aim of this study was to investigate the transfer of celecoxib into human milk. In one group of 3 breastfeeding patients on celecoxib at steady state, milk levels were determined at set intervals over 24 hours. Plasma levels were determined in 2 of their infants, age 17 and 22 months. In a second group of 2 subjects, intravenous lines were placed and a single 200-mg dose of celecoxib was followed by multiple paired plasma and milk samples over 8 hours. The mean milk-to-plasma ratio for celecoxib was 0.23 (95% confidence interval [CI]: 0.15-0.31). The average concentration of celecoxib in milk during the 8-hour dosing interval was 66 ug/L (95% CI: 41-89). The absolute infant dose averaged 9.8 ug/kg/d (95% CI: 6.2-13.4); the mean relative infant dose was 0.30%. Therefore, the average clinical dose transferred to the infant daily would be approximately 0.3% of the weight-adjusted maternal dose. ...

/MILK/ A 40 year old woman who was breastfeeding her 5 month old daughter was admitted to the hospital for surgery. In the postoperative period, she received four doses of celecoxib (100 mg twice/day) in addition to other medications. Starting about 5 hours after her last dose, four milk samples were obtained by hand expression over a 24 hour interval. The elimination half life range was 4.0-6.5 hours. These data suggest that celecoxib would be eliminated from breast milk about 24 hours after the last dose. Although maternal plasma was not obtained, the estimated milk:plasma ratios (based on reported adult plasma levels) were 0.27-0.59. the infant did not resume breastfeeding until 48 hours after the last dose. If she had nursed, the estimated maximum infant dose would have have been about 40 ug/kg/day.

/MILK/ /The aim of this study was/ to determine the milk-to-plasma (M/P) concentration ratio of celecoxib, and estimate likely infant exposure. Blood and milk were sampled for 48 hr after oral administration of celecoxib 200 mg to six lactating volunteers. The M/P ratio was derived from the area under the concentration-time curves (0-infinity) and the infant 'dose' estimated from celecoxib concentrations in milk. The median (range) M/P ratio was 0.18 (0.15-0.26). The median (range) infant 'dose' was 0.23% (0.17-0.30%) of the maternal dose, adjusted for weight. ...

A large part of celecoxib metabolism is mediated by cytochrome P450 2C9 in the liver with some contribution from CYP3A4 and CYP2C8 and possible contributions from CYP2D6. It is metabolized by biotransformation to carboxylic acid and glucuronide metabolites. Three metabolites, a primary alcohol, a carboxylic acid, and a glucuronide conjugate, have been found in human plasma after celecoxib administration. These are considered inactive metabolites in regards to COX enzyme inhibition. Patients who are known or suspected to have decreased cytochrome P450 2C9 activity or function, based on their previous history, should be administered celecoxib with caution as they may have abnormally high serum concentrations resulting from decreased metabolism celecoxib.
Celecoxib metabolism is primarily mediated via CYP2C9. Three metabolites, a primary alcohol, the corresponding carboxylic acid and its glucuronide conjugate, have been identified in human plasma. These metabolites are inactive as COX-1 or COX-2 inhibitors.

The effective half-life of celecoxib is approximately 11 hours when a single 200 mg dose is given to healthy subjects. The terminal half-life of celecoxib varies because of its low solubility, which prolongs absorption.

The plasma elimination half-life of celecoxib following oral administration of a single 200-mg dose under fasting conditions is about 11 hours, and the apparent plasma clearance of the drug is about 500 mL/minute; these parameters exhibit wide intraindividual variability, presumably because the low aqueous solubility of celecoxib prolongs absorption. The half-life of celecoxib is prolonged in patients with renal or hepatic impairment and has been reported to be 13.1 hours in patients with chronic renal insufficiency and 11 or 13.1 hours in patients with mild or moderate hepatic impairment, respectively.

Unlike most NSAIDs, which inhibit both types of cyclooxygenases (COX-1 and COX-2), celecoxib is a selective noncompetitive inhibitor of cyclooxygenase-2 (COX-2) enzyme. COX-2 is expressed heavily in inflamed tissues where it is induced by inflammatory mediators. The inhibition of this enzyme reduces the synthesis of metabolites that include prostaglandin E2 (PGE2), prostacyclin (PGI2), thromboxane (TXA2), prostaglandin D2 (PGD2), and prostaglandin F2 (PGF2). Resultant inhibition of these mediators leads to the alleviation of pain and inflammation. By inhibiting prostaglandin synthesis, non-steroidal anti-inflammatory drugs (NSAIDs) cause mucosal damage, ulceration and ulcer complication throughout the gastrointestinal tract. Celecoxib poses less of an ulceration risk than other NSAIDS, owing to its decreased effect on gastric mucosal prostaglandin synthesis when compared to placebo. Celecoxib exerts anticancer effects by binding to the cadherin-11 (CDH11)protein, which is thought to be involved in the progression of tumors, and inhibiting the 3-phosphoinositide-dependent kinase-1 (PDK-1) signaling mechanism. In addition, celecoxib has been found to inhibit carbonic anhydrase enzymes 2 and 3, further enhancing its anticancer effects. As mentioned in the pharmacodynamics section of this drug entry, celecoxib may cause an increased risk of thrombotic events. The risk of thrombosis resulting from COX-2 inhibition is caused by the vasoconstricting actions of thromboxane A2, leading to enhanced platelet aggregation, which is uncontrolled when the actions of prostacyclin, a platelet aggregation inhibitor, are suppressed through the inhibition of COX-2.
Nonsteroidal anti-inflammatory drugs (NSAIDs) are well-known causes of acute renal insufficiency and gastropathy in patients with chronic inflammatory diseases. This action is presumed to result from nonselective inhibition of both constitutive and inducible forms of prostaglandin H synthases, also known as the cyclooxygenase enzymes (i.e., COX-1 amd COX-2). Celecoxib (Celebrex) is a COX-2 enzyme inhibitor and has emerged as a preferred therapeutic agent for the treatment of rheumatoid arthritis as compared to other NSAIDs. Celecoxib has recently been the subject of criticism for its side effects, mainly arterial thrombosis and renal hemorrhage, although it is considered a superior drug in protecting the gastrointestinal tract. In the present study, we report that celecoxib not only inhibited COX-2, but also exhibited the property of inhibiting adenylyl cyclase, an important enzyme forming the intracellular second messenger 3',5'-adenosine monophosphate (cAMP) from adenosine triphosphate (ATP). Celecoxib also inhibited cholera toxin-stimulated cAMP formation, which indicated its ability to permeate cell membranes in order to reach intracellular adenylyl cyclase. It inhibited in vitro adenylyl cyclase activity in both human colonic epithelial cells and purified adenylyl cyclase from Bordetella pertussis. The IC50 of celecoxib for B. pertussis adenylyl cyclase was calculated to be 0.375 mM. Lineweaver-Burk analysis showed that the type of enzyme inhibition was competitive. The apparent Km and Vm of adenylyl cyclase was calculated as 25.0 nM and 7.14 nmol/min/mg, respectively. Celecoxib changed the Km value to 66.6 nM without affecting the Vmax. The current study suggests that apart from inflammation, celecoxib therapy could be further extended to diseases involving cAMP upregulation either by endogenous reactions or exogenous agents. These new data showing inhibition of adenylyl cyclase should be considered in light of the drug's pathological effects or in patients specifically excluded from treatment (e.g., asthmatics).

Cardiovascular disease is one of the leading causes of death worldwide, and evidence indicates a correlation between the inflammatory process and cardiac dysfunction. Selective inhibitors of cyclooxygenase-2 (COX-2) enzyme are not recommended for long-term use because of potentially severe side effects to the heart. Considering this and the frequent prescribing of commercial celecoxib, the present study analyzed cellular and molecular effects of 1 and 10 uM celecoxib in a cell culture model. After a 24-hr incubation, celecoxib reduced cell viability in a dose-dependent manner as also demonstrated in MTT assays. Furthermore, reverse transcription-polymerase chain reaction analysis showed that the drug modulated the expression level of genes related to death pathways, and Western blot analyses demonstrated a modulatory effect of the drug on COX-2 protein levels in cardiac cells. In addition, the results demonstrated a downregulation of prostaglandin E2 production by the cardiac cells incubated with celecoxib, in a dose-specific manner. These results are consistent with the decrease in cell viability and the presence of necrotic processes shown by Fourier transform infrared analysis, suggesting a direct correlation of prostanoids in cellular homeostasis and survival.

Celecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, has recently been shown to affect the development of different types of cancer. The present study utilized a murine H22 hepatocarcinoma model to investigate the molecular mechanisms involved in celecoxib-induced inhibition of tumor angiogenesis. Tumor-bearing mice were randomly divided into five groups: i) control; ii) low-dose celecoxib (50 mg/kg); iii) high-dose celecoxib (200 mg/kg); iv) 5-fluorouracil (5-FU), (20 mg/kg) and v) combination of 5-FU and celecoxib (50 mg/kg). The antitumor effect of celecoxib was determined by measuring tumor volume. Tumor angiogenesis was evaluated by microvessel density (MVD). Tumor histology and immunostaining for CD34 in endothelial cells were performed to detect MVD. The expression levels of phosphatase and tensin homologue deleted from chromosome 10 (PTEN), phosphatidylinositol 3-kinase (PI3K), phospho-Akt (P-Akt), COX-2, hypoxia-inducible factor-1a (HIF-1a) and vascular endothelial growth factor-A (VEGF-A) were detected by ELISA, immunohistochemistry and western blotting, respectively. We discovered substantial growth delay in murine H22 hepatoma as a result of celecoxib treatment. The inhibition rate of tumor growth induced by high-dose and low-dose celecoxib was 49.3 and 37.0%, respectively (P<0.05). The expression of PI3K, P-Akt, COX-2, HIF-1a, VEGF-A and PTEN in tumor tissues treated with celecoxib was demonstrated by immunohistochemistry, and the MVD was decreased in a dose-dependent manner (P<0.05). Reduced PI3K and P-Akt was particularly apparent in the high-dose celecoxib group (P<0.05). ELISA and western blotting data showed that the expression of PI3K, P-Akt, COX-2, HIF-1a and VEGF-A were reduced and PTEN was increased after treatment with celecoxib. In conclusion, the impact of celecoxib-induced tumor growth delay of murine H22 hepatocarcinoma may correlate with the inhibition of angiogenesis by reducing PI3K, P-Akt, COX-2, HIF-1a and VEGF-A expression and increasing PTEN expression in tumor tissue.
