Description
Overview of the medicine
Religox 120 mg Tablet is a selective cyclooxygenase-2 (COX-2) inhibitor, indicated for the symptomatic relief of various inflammatory and painful conditions, such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute gouty arthritis.
Uses & Indications
Dosage
Adults
Osteoarthritis: 60 mg once daily. Rheumatoid Arthritis & Ankylosing Spondylitis: 90 mg once daily. Acute Gouty Arthritis: 120 mg once daily (for a maximum of 8 days). The 120 mg dose is for acute conditions only and should not be used long-term.
Elderly
No dosage adjustment generally required, but caution is advised. Initiate at lowest effective dose.
Renal_impairment
Mild to moderate renal impairment: No dosage adjustment. Severe renal impairment: Not recommended.
How to Take
Religox tablets should be taken orally, with or without food. For faster onset of action, it may be taken without food. Do not chew or crush the tablet; swallow it whole with water.
Mechanism of Action
Religoxib selectively inhibits cyclooxygenase-2 (COX-2), an enzyme responsible for the synthesis of prostaglandins that mediate pain, inflammation, and fever. By inhibiting COX-2, religoxib reduces the production of these inflammatory mediators, thereby providing analgesic, anti-inflammatory, and antipyretic effects, while sparing COX-1, which is involved in gastric protection and platelet function.
Pharmacokinetics
Onset
Within 30-45 minutes for pain relief, full anti-inflammatory effect may take longer.
Excretion
Mainly excreted renally (about 70%) as metabolites, with a smaller portion excreted in feces (about 20%).
Half life
Approximately 20-26 hours, allowing for once-daily dosing.
Absorption
Rapidly absorbed after oral administration, reaching peak plasma concentrations in approximately 1-2 hours. Bioavailability is high, around 100%.
Metabolism
Extensively metabolized in the liver, primarily by cytochrome P450 (CYP3A4) enzymes, to inactive metabolites.
Side Effects
Contraindications
- Hypersensitivity to religoxib or any component of the tablet
- Active peptic ulceration or gastrointestinal bleeding
- Severe hepatic dysfunction
- Severe uncontrolled hypertension
- Established ischemic heart disease, peripheral arterial disease, and/or cerebrovascular disease
- Congestive heart failure (NYHA Class II-IV)
- Third trimester of pregnancy
Drug Interactions
Lithium
Religoxib may increase plasma lithium levels.
Diuretics
Reduced natriuretic effect and potential for renal impairment.
Methotrexate
Increased plasma levels of methotrexate, enhancing toxicity.
Oral contraceptives
May increase plasma concentrations of oral contraceptives.
Warfarin and other anticoagulants
Increased risk of bleeding.
ACE inhibitors and Angiotensin II Receptor Blockers (ARBs)
Reduced antihypertensive effect and increased risk of renal impairment.
Storage
Store in a cool and dry place, below 30°C. Protect from light and moisture. Keep out of reach of children.
Overdose
In case of overdose, symptomatic and supportive measures should be initiated. There is no specific antidote. Dialysis is unlikely to be effective due to high protein binding. Closely monitor vital signs and manage symptoms such as gastrointestinal upset, renal dysfunction, or cardiovascular events.
Pregnancy & Lactation
Pregnancy Category C (D in third trimester). Avoid use in the third trimester due to potential premature closure of the ductus arteriosus. Use only if potential benefit justifies potential risk to the fetus during the first and second trimesters. It is not known whether religoxib is excreted in human milk; caution should be exercised when administered to a nursing mother.

Clinical Trials
Clinical trials have demonstrated the efficacy and safety of Religoxib in the management of pain and inflammation associated with various musculoskeletal conditions, consistent with other COX-2 inhibitors. Long-term safety trials focused on cardiovascular and gastrointestinal outcomes have been conducted.
Lab Monitoring
- Regular monitoring of blood pressure, especially in patients with pre-existing hypertension.
- Renal function (e.g., serum creatinine, eGFR) should be monitored periodically, especially in elderly or patients with pre-existing renal impairment.
- Liver function tests (e.g., ALT, AST) may be considered, particularly during long-term therapy.
Doctor Notes
- Consider patient's cardiovascular risk factors and GI history before initiating treatment.
- Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.
- Monitor blood pressure and renal function, especially in high-risk patients.
- Advise patients on symptoms of GI and CV adverse events and when to seek medical attention.
Patient Guidelines
- Take the medicine exactly as prescribed by your doctor.
- Do not exceed the recommended dose or duration of treatment.
- Report any unusual symptoms, especially severe stomach pain, black stools, or swelling in your ankles, to your doctor immediately.
