Amidopyrine is white crystalline substance used as an analgesic and antipyretic.

Amikacin is an aminoglycoside antibiotic used to treat different types of bacterial infections.

Aminocaproic acid (Amicar)is a potent and orally active inhibitor of plasmin and plasminogen. 6-Aminocaproic acid is a potent antifibrinolytic agent. 6-Aminocaproic acid prevents clot lysis through the competitive binding of lysine residues on plasminogen, inhibiting plasmin formation and reducing fibrinolysis. 6-Aminocaproic acid can be used for the research of bleeding disorders.
