Meloxicam is a non-steroidal anti-inflammatory drug (NSAID) used to relieve the symptoms of arthritis (juvenile rheumatoid arthritis, osteoarthritis, and rheumatoid arthritis), such as inflammation, swelling, stiffness, and joint pain․ Meloxicam is sold under the brand name Mobic, among others․ Meloxicam belongs to the class of medications called oxicams․ It works by reducing hormones that cause inflammation and pain in the body․
Pharmacokinetics
Meloxicam is well absorbed after oral administration, with peak plasma concentrations occurring within 5-6 hours․ The absolute bioavailability is approximately 89%․ Food does not affect the extent of absorption, but it may delay the time to reach peak plasma concentrations by 1-2 hours․
Meloxicam is extensively bound to plasma proteins (99%)․ The volume of distribution is approximately 0․4 L/kg․ Meloxicam is metabolized in the liver by cytochrome P450 enzymes, primarily CYP2C9 and CYP3A4․ The major metabolite is 5'-carboxymeloxicam, which is inactive․
Meloxicam is eliminated primarily in the urine, with approximately 50% excreted as unchanged drug and 50% as metabolites․ The elimination half-life is approximately 20 hours․
Pharmacodynamics
Meloxicam is a non-steroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic properties․ It works by inhibiting the enzyme cyclooxygenase (COX), which is responsible for the production of prostaglandins, thromboxanes, and prostacyclins․ Prostaglandins are involved in the inflammatory process, and their inhibition leads to a reduction in inflammation, pain, and fever․
Meloxicam is a selective COX-2 inhibitor, which means that it has a greater affinity for COX-2 than for COX-1․ COX-1 is responsible for the production of prostaglandins that protect the stomach lining, kidneys, and platelets․ Inhibition of COX-1 can lead to gastrointestinal ulcers, bleeding, and kidney problems․ Meloxicam's selectivity for COX-2 makes it less likely to cause these side effects․
Clinical Trials
Meloxicam has been shown to be effective in reducing pain and inflammation in patients with osteoarthritis and rheumatoid arthritis․ In clinical trials, meloxicam has been shown to be as effective as other NSAIDs, such as ibuprofen and naproxen, in reducing pain and inflammation․ Meloxicam has also been shown to be well-tolerated, with a low incidence of side effects․
One study compared the efficacy and safety of meloxicam to ibuprofen in patients with osteoarthritis of the knee․ The study found that meloxicam was as effective as ibuprofen in reducing pain and stiffness and improving function․ Meloxicam was also better tolerated than ibuprofen, with a lower incidence of gastrointestinal side effects․
Another study compared the efficacy and safety of meloxicam to naproxen in patients with rheumatoid arthritis․ The study found that meloxicam was as effective as naproxen in reducing pain and swelling and improving function․ Meloxicam was also better tolerated than naproxen, with a lower incidence of gastrointestinal and cardiovascular side effects․
Overall, the clinical data suggest that meloxicam is an effective and well-tolerated NSAID for the treatment of osteoarthritis and rheumatoid arthritis․
Meloxicam is available as tablets, oral suspension, and injectable solution․ The recommended dosage of meloxicam varies depending on the condition being treated and the individual patient's response to the medication․

Patients with mild hepatic impairment (Child-Pugh score 5-6) should start with a dose of 7․5 mg once daily․ The dose may be increased to 15 mg once daily if needed․ Patients with moderate hepatic impairment (Child-Pugh score 7-9) should start with a dose of 7․5 mg every other day․ The dose may be increased to 7․5 mg once daily if needed․ Meloxicam is contraindicated in patients with severe hepatic impairment (Child-Pugh score 10-15)․
Renal Impairment
Patients with mild renal impairment (creatinine clearance 30-60 mL/min) do not require a dose adjustment․ Patients with moderate renal impairment (creatinine clearance 15-29 mL/min) should start with a dose of 7․5 mg every other day․ The dose may be increased to 7․5 mg once daily if needed․ Meloxicam is contraindicated in patients with severe renal impairment (creatinine clearance <15 mL/min)․
