4.3 Drug Warning

/BOXED WARNING/ WARNING: Cardiovascular Risk NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk. Meloxicam is contraindicated for the treatment of peri-operative pain in the setting of coronary artery bypass graft (CABG) surgery.

US Natl Inst Health; DailyMed. Current Medication Information for Meloxicam (meloxicam) tablets (Updated: May 2010). Available from, as of April 24, 2015: https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=6513e46b-3229-685b-c83b-2209454fae71


/BOXED WARNING/ WARNING: Gastrointestinal Risk: NSAIDs cause an increased risk of serious gastrointestinal 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 are at greater risk for serious gastrointestinal events.

US Natl Inst Health; DailyMed. Current Medication Information for Meloxicam (meloxicam) tablets (Updated: May 2010). Available from, as of April 24, 2015: https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=6513e46b-3229-685b-c83b-2209454fae71


Contraindications: Known hypersensitivity to meloxicam or any ingredient in the formulation. History of urticaria, angioedema, bronchospasm, severe rhinitis, or shock precipitated by aspirin or other NSAIAs. History of aspirin triad (aspirin sensitivity, asthma, and nasal polyps). Treatment of perioperative pain in the setting of coronary artery bypass graft (CABG) surgery.

American Society of Health System Pharmacists; AHFS Drug Information 2009. Bethesda, MD. (2009), p. 2162


Selective COX-2 inhibitors have been associated with an increased risk of serious adverse cardiovascular thrombotic events in certain situations. Several prototypical NSAIAs also have been associated with an increased risk of cardiovascular events. Findings from a recent systematic review of controlled observational studies and a meta-analysis of published and unpublished data from randomized studies of these agents suggest that use of celecoxib (dosage exceeding 200 mg daily), diclofenac, or indomethacin is associated with an increased risk of cardiovascular events. The possibility exists that meloxicam and ibuprofen also are associated with increased cardiovascular risk.

American Society of Health System Pharmacists; AHFS Drug Information 2009. Bethesda, MD. (2009), p. 2162

5 Pharmacology and Biochemistry
5.1 Pharmacology

Meloxicam is an anti-inflammatory, analgesic analgesic with antipyretic effects in fever. Prostaglandins are substances that contribute to inflammation. This drug also exerts preferential actions against COX-2, which may reduce the possible gastrointestinal effects of this drug. In humans, meloxicam has demonstrated the ability to decrease erythrocyte sedimentation rate(ESR) in patients with rheumatoid arthritis, and to decrease ESR, C-reactive protein (CRP), as well as aquaporin-1 expression. As with other NSAIDS, prolonged use of meloxicum can result in renal or cardiovascular impairment or thrombotic cardiovascular events. A note on gastrointestinal effects As meloxicam preferentially inhibits COX-2, it is thought to cause less gastrointestinal irritation compared to other NSAIDS. Despite this, it still carries a risk of gastric inflammation, bleeding and ulceration. In one study, patients on meloxicam suffered from gastrointestinal symptoms at a rate of 13% compared to 19% of those on [diclofenac]. GI events were found to be less severe in the meloxicam-treated patients.


5.2 MeSH Pharmacological Classification

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.)


Cyclooxygenase 2 Inhibitors

A subclass of cyclooxygenase inhibitors with specificity for CYCLOOXYGENASE-2. (See all compounds classified as Cyclooxygenase 2 Inhibitors.)

5.5 Absorption, Distribution and Excretion

Absorption

The absolute bioavailability oral capsules after a dose was 89% in one pharmacokinetic study. Cmax was reached 56 hours after administration of a single dose given after the first meal of the day. The Cmax doubled when the drug was administered in the fasting state. Despite this, meloxicam can be taken without regard to food, unlike many other NSAIDS. Meloxicam formulated for instillation with [bupivacaine] produced varied systemic measures following a single dose of varying strength. In patients undergoing bunionectomy, 1.8 mg of meloxicam produced a Cmax of 26 14 ng/mL, a median Tmax of 18 h, and an AUC of 2079 1631 ng\*h/mL. For a 9 mg dose used in herniorrhaphy, the corresponding values were 225 96 ng/mL, 54 h, and the AUC was not reported. Lastly, a 12 mg dose used in total knee arthroplasty produced values of 275 134 ng/mL, 36 h, and 25,673 17,666 ng\*h/mL.


Route of Elimination

Meloxicam is mainly eliminated through metabolism. Its metabolites are cleared through renal and fecal elimination. Less than <0.25% of a dose is eliminated in the urine as unchanged drug. About 1.6% of the parent drug is excreted in the feces.


Volume of Distribution

The volume of distribution of meloxicam is 10-15L. Because of its high binding to albumin, it is likely to be distributed in highly perfused tissues, such as the liver and kidney. Meloxicam concentrations in synovial fluid, measured after an oral dose, is estimated at 40% to 50% of the concentrations measured in the plasma. This drug is known to cross the placenta in humans.


Clearance

After an oral dose, the total clearance of meloxicam is 0.420.48 L/h. The FDA label indicates a plasma clearance from 7 to 9 mL/min. No dose changes are required in mild to moderate renal or hepatic impairment. The use of meloxicam in patients with severe renal or hepatic impairment has not been studied. FDA prescribing information advises against it.


The absolute bioavailability of meloxicam capsules was 89% following a single oral dose of 30 mg compared with 30 mg iv bolus injection. Following single intravenous doses, dose-proportional pharmacokinetics were shown in the range of 5 mg to 60 mg. After multiple oral doses the pharmacokinetics of meloxicam capsules were dose-proportional over the range of 7.5 mg to 15 mg. Mean Cmax was achieved within four to five hours after a 7.5 mg meloxicam tablet was taken under fasted conditions, indicating a prolonged drug absorption. With multiple dosing, steady state concentrations were reached by Day 5. A second meloxicam concentration peak occurs around 12 to 14 hours post-dose suggesting biliary recycling.

Administration of meloxicam capsules following a high fat breakfast (75 g of fat) resulted in mean peak drug levels (ie, Cmax) being increased by approximately 22% while the extent of absorption (AUC) was unchanged. The time to maximum concentration (Tmax) was achieved between 5 and 6 hours.

The mean volume of distribution (Vss) of meloxicam is approximately 10 L. Meloxicam is about 99.4% bound to human plasma proteins (primarily albumin) within the therapeutic dose range. The fraction of protein binding is independent of drug concentration, over the clinically relevant concentration range, but decreases to about 99% in patients with renal disease.

5.6 Metabolism/Metabolites

Meloxicam is almost completely metabolized. CYP2C9 is the main enzyme responsible for the metabolism of meloxicam with minor contributions from CYP3A4. Meloxicam has 4 major metabolites with no activity determined. About 60% of the ingested dose is metabolized to 5'-carboxy meloxicam from hepatic cytochrome enzyme oxidation of an intermediate metabolite, 5-hydroxymethylmeloxicam. Two other metabolites are likely produced via peroxidation.


Meloxicam is almost completely metabolized to four pharmacologically inactive metabolites. The major metabolite, 5'-carboxy meloxicam (60% of dose), from P-450 mediated metabolism was formed by oxidation of an intermediate metabolite 5'-hydroxymethyl meloxicam which is also excreted to a lesser extent (9% of dose). In vitro studies indicate that cytochrome P-450 2C9 plays an important role in this metabolic pathway with a minor contribution of the CYP 3A4 isozyme.

Patients' peroxidase activity is probably responsible for /two other/ metabolites which account for 16% and 4% of the administered dose, respectively.

Meloxicam is extensively metabolized to inactive metabolites in the liver, principally via the cytochrome P-450 (CYP) 2C9 isoenzyme, with minor contribution by CYP3A4. The drug and its metabolites are excreted in urine and feces, and meloxicam undergoes substantial biliary secretion and enterohepatic recirculation.

American Society of Health System Pharmacists; AHFS Drug Information 2009. Bethesda, MD. (2009), p. 2163


The metabolism of Meloxicam (ME) and the cytochrome(s) P450 (CYPs) involved were analysed by using primary human hepatocytes, human liver microsomes and microsomes from recombinant human B-lymphoblastoid cell lines. While human hepatocytes were capable of converting ME to a 5-hydroxymethyl metabolite (M7) and then to a 5-carboxyderivative (M5), human liver microsomes formed mostly only the 5-hydroxymethylderivative. The kinetics of the formation of M7 by human liver microsomes were biphasic with Km = 13.6 +/- 9.5 and 381 +/- 55.2 uM respectively. The corresponding Vmax were 33.7 +/- 24.2 and 143 +/- 83.9 pmol/min/mg protein respectively. CYP2C9 and, to a much lesser extent, CYP3A4 were found to convert ME to M7. The involvement of 2C9 was demonstrated by inhibition of tolbutamide hydroxylase activity in the presence of ME, inhibition of ME metabolism by sulphaphenazole, correlation between ME metabolism and tolbutamide hydroxylase activity and active metabolism of ME by recombinant 2C9. The involvement of 3A4 was shown by inhibition of ME metabolism by ketoconazole, correlation between ME metabolism and nifedipine oxidase activity and metabolism of ME by recombinant 3A4. Kinetics of the formation of M7 by the individual enzymes resulted in a Km = 9.6 uM and Vmax = 8.4 pmol/min/mg protein for 2C9 and a Km = 475 uM and Vmax = 23 pmol/min/mg protein for 3A4.

5.7 Biological Half-Life

The half-life of meloxicam is approximately 20 hours, which is considerably longer than most other NSAIDS. It can therefore be dosed without the need for slow-release formulations. Meloxicam applied together with [bupivacaine] for postsurgical analgesia had a median half-life of 33-42 hours, depending on dose and application site.


The mean elimination half-life (t1/2) ranges from 15 hours to 20 hours. The elimination half-life is constant across dose levels indicating linear metabolism within the therapeutic dose range.

5.8 Mechanism of Action

Meloxicam inhibits prostaglandin synthetase (cylooxygenase 1 and 2) enzymes leading to a decreased synthesis of prostaglandins, which normally mediate painful inflammatory symptoms. As prostaglandins sensitize neuronal pain receptors, inhibition of their synthesis leads to analgesic and inflammatory effects. Meloxicam preferentially inhibits COX-2, but also exerts some activity against COX-1, causing gastrointestinal irritation.


Meloxicam, an oxicam derivative that is structurally related to piroxicam, is a nonsteroidal anti-inflammatory agent (NSAIA) exhibiting analgesic, antipyretic, and anti-inflammatory actions. In vitro and in vivo studies indicate that meloxicam inhibits the cyclooxygenase-2 (COX-2) isoform of prostaglandin endoperoxide synthase (prostaglandin G/H synthase [PGHS]) to a greater extent than the COX-1 isoform. However, meloxicam's COX-2 selectivity is dose dependent and is diminished at higher dosages. Therefore meloxicam sometimes has been referred to as a "preferential" rather than "selective" COX-2 inhibitor.

American Society of Health System Pharmacists; AHFS Drug Information 2009. Bethesda, MD. (2009), p. 2162


To investigate the effect of meloxicam on human polymorphonuclear leukocyte (PMN) adhesion to human synovial cell (HSC), and to explore its mechanism. MTT colorimetry was used to determine the adhesion effect of PMN to HSC. Cell-ELISA and RT-PCR methods were used to determine the expression of ICAM-1 and VCAM-1. Nuclear transcription factor-kappa B (NF-kappa B) was measured by electrophoretic mobility shift assay (EMSA) method. Meloxicam was found to effectively inhibit TNF-alpha (50 u.mL-1 for 12 hr) and IL-1 beta (50 u.mL-1 for 12 hr)-induced adhesion of PMN to HSC (IC50 3.38 X 10(-7) mol.L-1 and 3.56 X 10(-6) mol.L-1, respectively) in a concentration-dependent manner. ICAM-1 protein and mRNA expression induced by TNF-alpha (50 u.mL-1) were inhibited by meloxicam at 1 X 10(-6)-1 X 10(-5) mol.L-1. The activation of NF-kappa B was also inhibited by meloxicam at 1 X 10(-6)-1 X 10(-5) mol.L-1. These results suggest that meloxicam inhibit TNF-alpha stimulated PMN-HSC adhesion and expression of ICAM-1 by suppressing the activity of NF-kappa B.

/Investigators/ compared the effects of therapeutically equivalent doses of meloxicam and indomethacin, a preferential inhibitor of the constitutive cyclooxygenase (COX-1), on platelet aggregation and platelet thromboxane formation, which are exclusively COX-1 dependent, physiological renal, and total body prostaglandin E2 (PGE2) production. In a randomized cross-over design, 14 healthy female volunteers received meloxicam 7.5 mg per day for 6 days or indomethacin 25 mg three times per day for 3 days; the wash-out period was 5 days, and drug intake was adapted to the menstrual cycle. On the day before treatment and on the last day of each treatment period the following parameters were evaluated: maximum platelet aggregation and thromboxane B2 (TXB2) formation in response to 1.0 mmol/L arachidonic acid; 24-hour urinary excretion of PGE2 and 7 alpha-hydroxy-5, 11-diketo-tetranor-prosta-1, 16-dionic acid (PGE-M), the index metabolites of renal and total body PGE2 synthesis, respectively, were assessed by gas chromatography/tandem mass spectrometry. Maximum platelet aggregation and TXB2 formation were almost completely inhibited by indomethacin (-87% and -99%, respectively; p < 0.001, each) as compared to control (100%), but remained unaffected by meloxicam (-1% and +4%, respectively). Meloxicam showed no significant effects on urinary PGE2 excretion (-13%) and only slight effects on PGE-M excretion (-22%; p < 0.05), whereas indomethacin reduced urinary PGE2 excretion (-43%; p < 0.05) as well as PGE-M excretion (-36%; p < 0.001). /This/ data shows, that meloxicam 7.5 mg per day is COX-1 sparing in humans in vivo.
