Topiroxostat
Uses of Topiroxostat
Topiroxostat is used to lower high uric acid levels in the blood (hyperuricaemia) and to prevent and manage gout. It belongs to a group of medicines called selective xanthine oxidase inhibitors.
It is commonly used for:
• Gout: Reduces elevated blood uric acid levels to prevent gout attacks, the sudden, severe joint pain and swelling caused by the build-up of uric acid crystals in the joints.
• Hyperuricaemia (high uric acid levels): Lowers chronically elevated uric acid in patients with or at risk of gout, including those with kidney disease or metabolic syndrome.
• Prevention of tophi formation: Reduces the accumulation of uric acid crystals in joints and soft tissues (tophi) over time with long-term use.
• Uric acid nephropathy: Helps protect the kidneys from damage caused by the deposition of uric acid crystals in the renal tubules.
Side effects of Topiroxostat
Increased liver enzymes
Gastrointestinal issues like diarrhoea, nausea, and vomiting
Skin rash
Fatigue
How Topiroxostat works
- Topiroxostat is a selective xanthine oxidase inhibitor. It works by blocking the enzyme xanthine oxidase, which is responsible for the final steps in uric acid production in the body.
- Purines, natural compounds found in food and produced by the body, are broken down into xanthine and hypoxanthine, which are then converted into uric acid by xanthine oxidase. By inhibiting this enzyme, Topiroxostat reduces the production of uric acid.
- With less uric acid being produced, blood uric acid levels fall over time. This reduces the formation and deposition of urate crystals in the joints and kidneys, which may help reduce the frequency of gout attacks.
- Unlike some other uric acid-lowering medicines, Topiroxostat selectively targets xanthine oxidase.
