Pharmacological properties:

Antimicrobic bacteriostatic means, streptocide. The mechanism of action is caused by competitive antagonism with paraaminobenzoic acid (PABK), oppression of a digidropteroatsintetaza, disturbance of synthesis of the tetrahydrofolic acid necessary for synthesis of purines and pyrimidines.
