Mechanism of Action
Meloxicam works by inhibiting the enzymes responsible for producing prostaglandins—chemical compounds in the body that trigger inflammation, pain, and fever.
- COX Enzyme Inhibition: Meloxicam inhibits cyclooxygenase (COX) enzymes, specifically COX-1 and COX-2.
- COX-2 Selectivity: At low-to-moderate doses, meloxicam exhibits relative selectivity for COX-2 (which mediates inflammatory response) over COX-1 (which protects stomach lining and supports kidney perfusion). However, at higher doses like 15 mg, this selectivity diminishes.
- Anti-Inflammatory Effect: Decreasing prostaglandin synthesis reduces tissue swelling, joint stiffness, and localized pain signal transmission.
Indications & Dosage
Approved Medical Uses
- Osteoarthritis (OA): Symptomatic relief of joint pain and inflammation.
- Rheumatoid Arthritis (RA): Reduction of joint swelling and pain in adults.
- Juvenile Rheumatoid Arthritis (JRA): Management of pauciarticular or polyarticular JRA in pediatric patients weighing .
Typical Dosage Guidelines
- Standard Adult Starting Dose: 7.5 mg taken orally once daily.
- Maximum Adult Dosage: 15 mg once daily (one ZC 26 tablet).
- Administration: Take with or without food once daily at approximately the same time. Taking it with meals or milk can help reduce potential stomach upset.
- Duration: Prescribers aim for the lowest effective dose for the shortest possible duration to minimize cardiovascular and gastrointestinal risks.
Side Effects
Like all NSAIDs, meloxicam can cause side effects ranging from mild discomfort to severe health complications.
Common Side Effects
- Dyspepsia (indigestion) and heartburn
- Nausea, diarrhea, or flatulence
- Abdominal discomfort or mild cramps
- Dizziness or lightheadedness
- Mild headaches
Serious Side Effects (Seek Immediate Medical Care)
- Gastrointestinal Distress: Black/tarry stools, vomiting blood, or severe upper stomach pain.
- Renal Dysfunction: Decreased urination, swelling in legs or feet, or unexplained fluid retention.
- Hepatic Toxicity: Yellowing of the skin or eyes (jaundice), dark urine, or severe upper-right abdominal pain.
- Severe Skin Reactions: Rash, blistering, or peeling (e.g., Stevens-Johnson syndrome).
- Allergic Reactions: Anaphylaxis, swelling of the face, tongue, or throat, or sudden shortness of breath.
Black Box Warnings & Precautions
The FDA places Boxed Warnings on meloxicam due to significant safety risks associated with NSAID therapy.
Cardiovascular Risk
- Thrombotic Events: NSAIDs increase the risk of serious, potentially fatal cardiovascular thrombotic events, including myocardial infarction (heart attack) and stroke.
- Surgical Contraindication: Meloxicam is strictly contraindicated for perioperative pain management in the setting of Coronary Artery Bypass Graft (CABG) surgery.
Gastrointestinal Risk
- Bleeding & Perforation: Increased risk of serious gastrointestinal inflammation, bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time without warning symptoms. Elderly patients and those with a prior history of peptic ulcer disease are at higher risk.
Key Precautions
- Pregnancy: Avoid use starting around 20 weeks of gestation or later due to risks of fetal kidney damage and premature closure of the fetal ductus arteriosus.
- Hypertension & Heart Failure: Meloxicam can precipitate new-onset hypertension or worsen existing high blood pressure and fluid retention.
- Renal Toxicity: Long-term use can cause renal papillary necrosis and kidney insufficiency, particularly in dehydrated patients or those taking diuretics, ACE inhibitors, or ARBs.
- Drug Interactions: Exercise caution when co-administering with anticoagulants (e.g., warfarin), aspirin, selective serotonin reuptake inhibitors (SSRIs), lithium, or methotrexate.
