Abstract
PURPOSE:To obtain a pharmaceutical composition, containing pirenzepines, hardened oil and polyoxyethylene polyoxypropylene copolymer, capable of inhibiting bitterness without deteriorating elution property and useful for gastritis, etc. CONSTITUTION:A pharmaceutical composition obtained by containing pirenzepine expressed by the formula or acid addition salts thereof (e.g. hydrochloride), hardened oil (e.g. hardened castor oil) and polyoxyethylene polyoxypropylene copolymer. Since the compound expressed by the formula which is a principal agent and acid addition salts thereof strong bitterness, preparation of a pharmaceutical with prevented bitterness is required for facilitating administration. The above-mentioned composition suppresses bitterness and has properties of delaying elution of the principal drug. Furthermore, aforementioned copolymer improves the delayed elution by the hardened oil. Since rapid solubility is also required as a medicine for gastritis, etc., a cellulosic water-soluble high polymer is preferably further added.
