Ikynol

Allopurinol, the active ingredient in Ikynol, is a xanthine oxidase inhibitor presented as an oral tablet for oral use. It lowers uric acid production and is used to manage gout, hyperuricemia, and to prevent tumor lysis syndrome in patients undergoing chemotherapy.

GNH USA supplies Ikynol as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. Allopurinol is approved in the European Union for these indications and is manufactured under strict GMP conditions.

Allopurinol is a xanthine oxidase inhibitor used to manage conditions related to excess uric acid.

- Gout: Reduces serum uric acid levels to prevent acute attacks and chronic joint damage. - Hyperuricemia: Lowers uric acid concentration in patients with elevated levels not due to gout. - Tumor lysis syndrome: Prevents rapid uric acid accumulation during chemotherapy for high‑risk malignancies. - Uric acid nephrolithiasis: Decreases risk of kidney stone formation by lowering uric acid.

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

Common Side Effects: - Rash or mild skin irritation. - Nausea, vomiting or abdominal discomfort. - Diarrhea or loose stools. - Elevated liver enzymes detected on routine labs. - Itching (pruritus) without rash. - Altered taste sensation.

Serious or Rare Side Effects: - Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Severe hypersensitivity syndrome with fever and organ involvement. - Bone marrow suppression leading to anemia or leukopenia. - Acute hepatic failure. - Acute renal impairment or interstitial nephritis. - Life‑threatening anaphylactic reactions.

When prescribing Allopurinol, clinicians should consider several safety factors.

- Renal function: Adjust dose in patients with impaired renal clearance. - Hepatic function: Monitor liver enzymes during therapy. - Allergy history: Avoid if known hypersensitivity to allopurinol or its metabolites. - Drug interactions: Review concomitant medications for potential interactions. - Pregnancy and lactation: Use only if benefits outweigh potential risks. - Store at ambient temperature: Keep below 25°C in the original packaging, protect from moisture.

Allopurinol interacts with several medicines; careful review is essential.

Major Interactions (Avoid): - Azathioprine or mercaptopurine: May cause severe bone marrow suppression. - Amoxicillin‑clavulanate: Increases risk of serious skin reactions such as SJS. - Warfarin: Allopurinol can potentiate anticoagulant effect, raising INR. - Cyclosporine: May increase allopurinol plasma levels, risking toxicity.

Moderate Interactions (Monitor Closely): - Thiazide diuretics: Can reduce uric acid‑lowering efficacy. - ACE inhibitors or ARBs: May modestly increase serum potassium. - NSAIDs: May affect renal function when combined with allopurinol. - Theophylline: Allopurinol can decrease its clearance, requiring dose adjustment.
