Nimesulide Ingen Pharma (Nimesulide)

• Nimesulide acts as an NSAID to alleviate pain and inflammation across several common conditions.
• Acute pain: Provides rapid analgesic effect for short‑term musculoskeletal discomfort.
• Fever: Lowers elevated body temperature associated with infections or inflammatory states.
• Osteoarthritis: Reduces joint pain and improves functional mobility in chronic degenerative disease.
• Dysmenorrhea: Alleviates menstrual cramps and associated pelvic pain.

• Nimesulide selectively inhibits cyclo‑oxygenase‑2 (COX‑2), the enzyme responsible for converting arachidonic acid into prostaglandins that mediate pain, fever and inflammation. By sparing COX‑1 activity, it aims to preserve gastric mucosal protection while decreasing the synthesis of inflammatory prostaglandins, resulting in analgesic, antipyretic and anti‑inflammatory effects. The inhibition is dose‑dependent and contributes to reduced peripheral sensitisation of nociceptors. This pharmacological profile underlies its clinical utility in short‑term treatment regimens.

Nimesulide may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia or abdominal pain.
• Headache: mild to moderate intensity.
• Dizziness or vertigo.
• Skin rash: mild erythema or pruritus.

Serious or Rare Side Effects

• Hepatotoxicity: elevated liver enzymes or severe liver injury.
• Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Blood disorders: agranulocytosis or thrombocytopenia.
• Renal impairment: acute kidney injury or reduced renal function.

When prescribing Nimesulide, clinicians should consider several safety precautions to minimise risk.

• Liver function: assess hepatic status before initiation and monitor periodically.
• Contraindications: avoid in patients with known hypersensitivity to nimesulide or other NSAIDs.
• Concomitant NSAIDs: do not combine with other non‑steroidal anti‑inflammatory drugs to reduce gastrointestinal toxicity.
• Renal function: use cautiously in patients with renal impairment and monitor creatinine.
• Cardiovascular risk: evaluate for existing cardiovascular disease as NSAIDs may increase risk.
• Store at ambient temperature: keep below 25 °C in the original packaging, protect from moisture and light.

Nimesulide can interact with several medicines, altering efficacy or safety.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased bleeding risk.
• Other NSAIDs or aspirin: heightened gastrointestinal ulceration.
• Lithium: elevated serum lithium levels.
• Methotrexate: reduced clearance leading to toxicity.
• Cyclosporine: increased nephrotoxicity.

Moderate Interactions (Monitor Closely)

• Antihypertensives (ACE inhibitors, ARBs, diuretics): possible reduction in antihypertensive effect.
• Corticosteroids: additive risk of gastrointestinal bleeding.
• SSRIs: increased bleeding tendency.
• Oral hypoglycemics: potential alteration of blood glucose control.
• Diuretics: may affect renal handling of the drug.
