Abstract

PURPOSE: To prepare an acetylsalicylic acid solid preparation, stable to the discoloration during storage, by incorporating α-starch as a stabilizer.
CONSTITUTION: A solid preparation containing acetylsalicylic acid (aspirin) or its derivative useful as an antipyretic analgesic agent, is compounded with α-starch (preferably 1W20wt% on the basis of the whole composition). The acetylsalicylic acid solid preparation is easily hydrolyzed with water to salicylic acid and acetic acid, and changes its color to reddish brown, etc. especially in the presence of a trace of heavy metals, particularly Fe, Co, etc.. Addition of α-starch suppresses the discoloration to enable stable storage and inhibits lowering of the effectivity of the preparation caused by the hydrolysis of acetylsalicylic acid.
