Don’t Buy Allopurinol – There’s Better Gout Fixers

This “Buy Allopurinol” article was first published in May 2008.

I republish it here as part of ongoing website maintenance. Please note that benzbromarone is restricted in many countries due to concerns about effects on the liver.

Why Buy Allopurinol?

Millions of gout sufferers buy allopurinol, but most are wasting their money.

There have been many concerns recently about the way allopurinol is administered.

Most gout patients do not get the proper advice or monitoring to ensure dosage is effective.

New research indicates that probenecid is almost 3 times better than allopurinol.

Benzbromarone is almost 4 times better.

OBJECTIVES:
To investigate the efficacy and tolerability of allopurinol as first-choice uric acid lowering (antihyperuricemic) treatment for gout, and compare the efficacy and tolerability of benzbromarone and probenecid as second-choice treatment.
METHODS:
Prospective, multi-center, open-label, randomized controlled trial (RCT) of gout patients with normal kidney function.

Patients were given 300 mg allopurinol for 2 months (stage 1).

When allopurinol was not tolerated or failed to attain target serum urate concentrations (sUr)

RESULTS:

Ninety-six patients were enrolled in stage 1.

Eighty-two patients (85%) were eligible for the analysis of stage 1: serum urate concentrations concentrations decreased 36[+/-11]% (mean[+/-SD]) from baseline; twenty patients (24%) attained target serum urate concentrations

Sixty-two patients were enrolled in stage 2: 27 patients received benzbromarone (3 lost to follow-up) and 35 received probenecid (4 lost to follow-up).

With benzbromarone 22 out of 24 patients (92%) were treated successfully.

Treatment success with probenecid was 20 out of 31 patients (65%) (p=0.03 compared with benzbromarone). Compared with baseline values, serum urate concentrations decreased 64[+/-9]% applying benzbromarone and decreased 50[+/-7]% applying probenecid (p<0.001).

CONCLUSION:
This study demonstrates a poor efficacy and tolerability profile of allopurinol 300 mg/day to attain a biochemical predefined target level of serum urate concentrations

In stage 2, benzbromarone 200 mg/day is more effective and better tolerated than probenecid 2000 mg/day.

I have made some slight changes to the gout research abstract from Medline to make it easier to read. The original abstract and full report are on the ARD website.

You can discuss this research, and all aspects of why to buy allopurinol (or not) on the gout resources forum.
