Zyloric 300 is a medication primarily used in the treatment and management of gout and certain types of kidney stones. The active ingredient in Zyloric 300 is allopurinol, which works by reducing the production of uric acid in the body. High levels of uric acid can lead to gout attacks, characterized by sudden and severe pain in the joints, and can also contribute to the formation of kidney stones. By lowering uric acid levels, Zyloric 300 helps to prevent these painful conditions. It is typically prescribed as a long-term treatment and must be taken according to the healthcare provider's instructions to be effective. Patients taking Zyloric 300 are often advised to stay well-hydrated and to follow a diet low in purines, substances found in certain foods that can increase uric acid levels.
