Arsphenamine and Bismuth chemically combined in one molecule for intramuscular injection - each aiding the activity of the other. *In early lues, clinically reported to be at least equal to modern combined treatment. Also to have given best results in Wassermann-Fast cases. *In late stages, Bismarsen does not shock the patient and exerts a distinct tonic effect. Excellent record in cardiovascular lues.
