摘要:
A remedy for inflammatory intestinal diseases which contains as the active ingredient 9-(4-acetyl-3-hydroxy-2-n-propylphenoxymethyl)-3-(1H-tetrazol-5-yl)-4H-pyrido[1,2-a]pyrimidine-4-one represented by the formula: ##STR1## or a physiologically acceptable salt thereof. The compound specified in the present invention can remedy not only inflammatory responses caused in inflammatory intestinal diseases in a short time but also remove the symptoms deriving from digestive organs, which are caused together with the inflammatory response of the intestine.
摘要:
Pyrido[1,2-a]pyrimidine derivatives of the general formula [I] and their physiologically acceptable salts are provided: ##STR1## where R is a hydrogen atom, a halogen atom or a methyl group, and n is 0, 1 or 2. The pyrido[1,2-a]pyrimidine derivatives and their salts exhibit an excellent antagonistic effect on slow-reacting substance of anaphylaxis and, therefore, are useable for the treatment of allergic diseases.
