Allopurinol: An Overview

Allopurinol is a prescription drug that belongs to a class of medications known as xanthine oxidase inhibitors. It is primarily used to treat conditions associated with high levels of uric acid in the blood and urine, such as gout, kidney stones, and certain types of cancer treatment. Allopurinol works by blocking the enzyme xanthine oxidase, which is responsible for the production of uric acid in the body.

Uses of Allopurinol

Allopurinol is commonly prescribed for the following conditions:

• Gout: Allopurinol helps to lower uric acid levels in the blood, reducing the risk of painful gout flare-ups.
• Elevated serum uric acid levels: Allopurinol can be used to manage high levels of uric acid in the blood, which can lead to the formation of uric acid crystals and the development of kidney stones.
• Recurrent kidney stones: By reducing uric acid levels, allopurinol can help prevent the formation of new kidney stones or the recurrence of existing ones.
• Cancer treatment: Allopurinol may be used to manage high uric acid levels that can occur as a side effect of certain cancer therapies, such as chemotherapy.
