Uricosuric medications for chronic gout.

Area of Science:

• Rheumatology
• Pharmacology
• Clinical Trials

Background:

• Uricosuric agents are used for gout treatment.
• Evidence on their benefit and safety is limited.

Purpose of the Study:

• Assess benefits and harms of uricosuric medications.
• Evaluate uricosurics in chronic gout treatment.

Main Methods:

• Searched multiple databases for RCTs and CCTs.
• Included studies comparing uricosurics (benzbromarone, probenecid, sulphinpyrazone) with placebo or other treatments.
• Assessed outcomes like gout attacks, serum urate normalization, and adverse events.

Main Results:

• Moderate evidence suggests benzbromarone and allopurinol have similar effects on serum urate normalization.
• Benzbromarone may be more effective than probenecid for serum urate normalization.
• Benzbromarone showed fewer adverse events and withdrawals compared to probenecid.

Conclusions:

• Benzbromarone likely offers similar serum urate normalization as allopurinol.
• Benzbromarone appears more effective than probenecid for gout.
• Evidence on uricosurics' safety and effectiveness is limited, with some uncertainty.
