Lactam compounds of the formula ##STR1## in which: R is hydrogen, alkyl or cycloalkyl; R.sup.1 is hydrogen, alkyl, alkenyl or cycloalkyl; R.sup.2 is alkyl, alkenyl, cyano or a carbonyl substituted hydroxyl, alkyl, alkoxy, amino, alkylamino or hydrazino; or R.sup.1 and R.sup.2 together represent alkylidene cycloalkylidene; or R.sup.1, R.sup.2 and the adjacent carbon atom form a spirocyclic ring; n is 0 or 1; A is a --Co--NH--, --NH--CO--NH-- or --O--CO--NH--; X is a valency bond, alkylene or alkenylene; and R.sup.3 is optionally substituted phenyl, pyridyl, methylenedioxyphenyl or a five-membered heterocycle; or when X is a valency bond, R.sup.3 can also be an optionally substituted alkyl or alkino group, or cycloalkyl. The compounds are useful for the inhibition of erythrocyte and thrombocyte aggregation.
