Platelet Activating Factor (PAF) antagonists which comprises the compounds of the formula (I):
wherein A is an optionally substituted phenyl or an optionally substituted heterocyclic group; X is methylene group, carbonyl group or thiocarbonyl group; R¹, R² and R³ are independently a lower alkyl group, and their salts are excellent in absorption from the intestinal canal.Among the compounds of the formula (I), those wherein A is an optionally substituted 2,3-dihydro-1-benzoxepin-4-yl group are novel compounds and exhibit excellent PAF antagonism.
