Purinol Tablet 300 mg contains Allopurinol, a potent xanthine oxidase inhibitor used to manage hyperuricemia and gout. Hyperuricemia, characterized by elevated uric acid levels in the blood, can lead to painful gout attacks, uric acid kidney stones, and tophi formation. Purinol 300 mg is a higher-dose formulation intended for patients requiring significant uric acid reduction, such as those with recurrent gout, tumor lysis syndrome, or severe chronic hyperuricemia.

Allopurinol works by inhibiting uric acid production, preventing the formation and deposition of urate crystals in joints and tissues. This tablet provides effective, long-term management of uric acid levels, protecting the kidneys and joints while improving patient quality of life.

Mechanism of Action

Allopurinol, the active ingredient in Purinol 300 mg, is a xanthine oxidase inhibitor that:

• Blocks xanthine oxidase, the enzyme responsible for converting hypoxanthine to xanthine and xanthine to uric acid

• Reduces serum and urinary uric acid levels, preventing urate crystal formation

• Protects the kidneys and joints from damage caused by urate deposition

• Helps prevent acute gout attacks and chronic complications such as tophi

By reducing uric acid at its source, Purinol 300 mg addresses the underlying cause of hyperuricemia, not just the symptoms.

Indications

Purinol Tablet 300 mg is indicated for:

• Chronic gout requiring significant uric acid reduction

• Hyperuricemia secondary to cancer therapy (tumor lysis syndrome)

• Prevention and treatment of uric acid nephrolithiasis (kidney stones)

• Management of secondary hyperuricemia due to renal impairment, metabolic disorders, or certain medications

• Prevention of tophi formation and other chronic complications of urate crystal deposition

This higher-dose formulation is particularly useful for patients who do not achieve target uric acid levels with lower doses.

Dosage and Administration

• The typical starting dose is 100 mg daily, gradually titrated up to 300 mg daily or higher, depending on uric acid levels and patient tolerance

• Tablets should be taken orally with water, preferably after meals to reduce gastrointestinal irritation

• Dose adjustments may be required in renal impairment since allopurinol is primarily excreted by the kidneys

• Regular monitoring of serum uric acid levels, liver function, and kidney function is recommended

• Gradual dose escalation helps prevent acute gout flares at the start of therapy

• Prevents tophi development and chronic joint damage

• Suitable for long-term therapy with proper medical supervision

• Improves overall quality of life for patients with chronic hyperuricemia

Precautions

• Use cautiously in patients with renal or liver impairment

• Maintain adequate hydration to reduce the risk of kidney stones

• Monitor uric acid, liver, and kidney function during therapy

• Inform the physician of other medications, especially azathioprine, mercaptopurine, or theophylline, as dose adjustments may be necessary

• Avoid abrupt discontinuation without medical advice

Storage

Store in a cool, dry place below 30°C, protected from light and moisture. Keep out of reach of children, and ensure the container is tightly closed.
