Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic and fever reducer effects. It is a derivative of oxicam, closely related to piroxicam, and falls in the enolic acid group of NSAIDs.

Meloxicam inhibits cyclooxygenase (COX), the enzyme responsible for converting arachidonic acid into prostaglandin H2—the first step in the synthesis of prostaglandins, which are mediators of inflammation. Meloxicam has been shown, especially at its low therapeutic dose, selectively to inhibit COX-2 over COX-1.

Meloxicam concentrations in synovial fluid range from 40% to 50% of those in plasma. The free fraction in synovial fluid is 2.5 times higher than in plasma, due to the lower albumin content in synovial fluid as compared to plasma. The significance of this penetration is unknown, but it may account for the fact that it performs exceptionally well in treatment of arthritis in animal models.

DRUG INTERACTIONS: In studies where meloxicam was administered with cimetidine (Tagamet), digoxin (Lanoxin), and methotrexate (Rheumatrex), there were no drug interactions. Meloxicam may interfere with a class of drugs called ACE inhibitors, e.g., captopril (Capoten) and ramipril (Altace) or the water pill, furosemide (Lasix), that are used for controlling high blood pressure,. This may lead to an increase in blood pressure, and as a result, the dose of ACE inhibitor or Lasix may need to be changed when starting or stopping meloxicam.

Meloxicam should be avoided by patients with a history of asthma attacks, hives or other allergic reactions to aspirin or other NSAIDs.

If aspirin is taken with meloxicam there may be an increased risk for developing an ulcer.

Persons who have more than 3 alcoholic beverages per day may be at increased risk of developing stomach ulcers when taking meloxicam or other NSAIDs.

Cholestyramine (Questran), colestipol (Colestid) and colesevelam (Welchol) may decrease the effectiveness of meloxicam by preventing its absorption from the intestine.

Lithium (Eskalith or Lithobid) blood levels may increase or decrease after meloxicam therapy starts or stops. Therefore, both the patient taking lithium and the blood level of lithium need to be evaluated when starting or stopping meloxicam.
