Pharmacological action

Antimicrobial bacteriostatic agent, sulfonamide. The mechanism of action is due to competitive antagonism with para-aminobenzoic acid, inhibition of dihydropteroate synthase, impaired synthesis of tetrahydrofolate acid, necessary for the synthesis of purines and pyrimidines. Active against gram-positive and gram-negative cocci, Escherichia coli, Shigella spp., Klebsiella spp., Vibrio cholerae, Clostridium perfringens, Bacillus anthracis, Corynebacterium diphtheriae, Yersinia pestis, Chlamydia scesii, Act.

Pharmacokinetics

Absorption - fast (mainly in the small intestine). Communication with plasma proteins -75-86%. It penetrates well into tissues (including the lungs, cerebrospinal fluid). It is metabolized in the liver by acetylation. The half-life (T1 / 2) is 7 hours. It is excreted by the kidneys by glomerular filtration. Acetylated metabolites when concentrated in the urine may precipitate. The solubility of metabolites improves with alkalization of urine.

Dosage and administration

Inside, 1 g 4-6 times a day. With pneumonia and meningitis at the first dose - 2 g for children - at the rate of 0.1 g / kg at the first dose, then 0.25 g / kg every 4, 6, 8 hours.

Drug Interactions

Reduces the effectiveness of bactericidal antibiotics that act only on fissile microorganisms (including penicillins and cephalosporins). Increases (mutually) hematotoxicity of chloramphenicol, tiamazole. Benzocaine, procaine reduce antimicrobial activity (PABA is released during hydrolysis). Ascorbic acid, hexamethylenetetramine increase the risk of crystalluria. NSAIDs, hypoglycemic drugs (sulfonylurea derivatives), phenytoin and coumarin anticoagulants increase the severity of side effects. Antacids reduce intestinal absorption. With toxoplasmosis, a combination with pyrimethamine is possible. Myelotoxic drugs increase the manifestations of hematotoxicity of the drug.
