Abstract

Butazolidin alka tablets (Geigy) contain 100 mg phenylbutazone ensheathed in a compression-coated ‘mantle’ of dried aluminium hydroxide gel BP 100 mg and magnesium trisilicate BP 150 mg. They are promoted for use in patients who have manifested ‘gastric sensitivity’ while taking uncoated phenylbutazone or other anti-rheumatic drugs.
