Abstract

Novel carbaphens are provided of the formula ##STR1## wherein R is OH, OCON(CH.sub.3).sub.2 or OCONHCH.sub.3, and R' is H, OH or sub.2 OCON(CH.sub.3).sub.2, stereoisomers thereof, pharmaceutically-acceptable salts thereof or mixtures thereof. Compositions comprise the carbaphens with pharmaceutically acceptable carriers, and they may further comprise other drugs as well. Methods of treating patients either prophylactically or therapeutically which suffer from organophosphate poisoning, coronary insufficiency, cerebral vasospasms, spastic cholitis and cholecystitis comprise the administration of the carbaphens of the invention.
