Probucol Quantitative Regression Swedish Trial

The adverse effects of probucol have been reviewed (1). As the Probucol Quantitative Regression Swedish Trial (PQRST) showed no improvement in lumen volume of the femoral artery in patients given probucol plus coles-tyramine, as compared with those given colestyramine alone, doubt has been raised about its efficacy (2).
