INCLUDING COMPLEXES OF N-ETHOXYCARBONYL-3-MORPHOLINO-SYDNONIMINE OR ITS SALTS FORMED WITH CYCLODEXTRIN DERIVATIVES, PRODUCTION OF THESE COMPLEXES AND PHARMACEUTICAL COMPOSITIONS THAT CONTAIN THESE COMPLEXES

摘要

Clathrates (I) of N-ethoxycarbonyl-3- morpholino-sydnonimine (II) or its salts with cyclodextrin derivs. (III) are new. N.B., cpds. (III) include unsubstd. beta- and gamma-cyclodextrins. (II) is an anti-angina and anti-ischaemic agent (molsidomin) useful for prevention and treatment of angina pectoris. It also has antiarrhythmic, fibrinolytic, platelet aggregation inhibitory and hypotensive activity. Pref. (III) are selected from beta-cyclodextrin (BCD), gamma-cyclodextrin, heptakis-2,6,O-dimethyl -beta-cyclodextrin and hydroxypropyl- beta-cyclodextrin.
