摘要:
Pharmacologically-active 3-aminosydnonimines (which are optionally substituted in the N.sup.6 -position) and their physiologically-acceptable acid-addition salts are compounded into standard dosage-form medicament compositions and are useful for prophylaxis for and treatment of cardiovascular-system disorders, such as high blood pressure and angina pectoris. The 3-aminosydnonimines are 3-[4-(lower alkoxy)carbonylpiperazin-1-yl]sydnonimines and 3-[N-(lower alkyl)-N-(tetrahydro-3-thienyl S,S-dioxide)]-sydnonimines.
