Description
Overview of the medicine
Docopa 400 mg Tablet contains Docopaxib, a selective COX-2 inhibitor, used for the symptomatic treatment of osteoarthritis, rheumatoid arthritis, and acute pain. It reduces pain and inflammation.
Uses & Indications
Dosage
Adults
Osteoarthritis: 200 mg once daily or 100 mg twice daily. Rheumatoid Arthritis: 100 mg or 200 mg twice daily. Acute Pain: 400 mg initially, followed by 200 mg if needed on the first day. Subsequent days: 200 mg twice daily.
Elderly
No specific dose adjustment is usually required, but caution is advised. Start with the lowest effective dose.
Renal_impairment
Mild to moderate impairment: No dose adjustment. Severe impairment: Use with caution, consider lower doses or alternative treatment.
How to Take
Docopa 400 mg Tablet should be taken orally, with food or milk, to minimize gastrointestinal discomfort. Do not crush or chew the tablet; swallow it whole.
Mechanism of Action
Docopaxib selectively inhibits cyclooxygenase-2 (COX-2) enzyme, which is primarily responsible for the synthesis of prostaglandins involved in pain, inflammation, and fever. By inhibiting COX-2, it reduces these inflammatory responses without significantly affecting COX-1, which protects the stomach lining.
Pharmacokinetics
Onset
Pain relief starts within 30-60 minutes, anti-inflammatory effects within hours.
Excretion
Mainly excreted in urine (approximately 50-60%) and feces (approximately 25-30%) as metabolites, with less than 1% as unchanged drug.
Half life
Approximately 8-12 hours.
Absorption
Well absorbed orally, peak plasma concentrations typically achieved within 2-4 hours.
Metabolism
Extensively metabolized in the liver, primarily via cytochrome P450 (CYP2C9).
Side Effects
Contraindications
- Hypersensitivity to docopaxib, sulfonamides, or any components of the formulation
- History of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs
- Active peptic ulceration or gastrointestinal bleeding
- Severe hepatic impairment
- Severe renal impairment (creatinine clearance < 30 mL/min)
- Late stages of pregnancy (third trimester)
- Established ischemic heart disease, peripheral arterial disease, and/or cerebrovascular disease
Drug Interactions
Lithium
May increase plasma lithium levels, leading to toxicity.
Diuretics
May reduce natriuretic effect.
Fluconazole
May increase docopaxib plasma concentrations.
Methotrexate
May increase methotrexate toxicity.
Warfarin and other anticoagulants
Increased risk of bleeding.
ACE inhibitors/Angiotensin II receptor blockers (ARBs)
May reduce the antihypertensive effect and increase the risk of renal impairment.
Storage
Store in a cool, dry place below 30°C. Protect from light and moisture. Keep out of reach of children.
Overdose
Symptoms may include lethargy, drowsiness, nausea, vomiting, and epigastric pain. Gastrointestinal bleeding can occur. Rarely, hypertension, acute renal failure, respiratory depression, and coma may occur. Management: Symptomatic and supportive treatment. Gastric lavage and/or activated charcoal may be considered within the first hour of ingestion.
Pregnancy & Lactation
Pregnancy Category C (first and second trimesters), Category D (third trimester). Avoid in late pregnancy due to potential for premature closure of the ductus arteriosus and impaired renal function in the fetus. Not recommended during breastfeeding as it may pass into breast milk.
