Sulfametoxydiazine (INN) or sulfamethoxydiazine (USAN: sulfameter) is a long-acting sulfonamide antibacterial, shows bacteriostatic effects against Gram positive and Gram negative bacteria in vivo. It is used as a leprostatic agent and in the treatment of urinary tract infections. Orally active. Sulfonamides block the synthesis of dihydrofolic acid by inhibiting the enzyme dihydropteroate synthase. Sulfonamides are competitive inhibitors of bacterial para-aminobenzoic acid (PABA), which is required for bacterial synthesis of folic acid. Sulfameter is a dihydrofolate reductase (DHFR) inhibitor. Mode of resistance is via the alteration of dihydropteroate synthase or alternative pathway for folic acid synthesis.

Loading dose first-day only (single dose): 1500 mg (3 tablets) Daily maintenance (single dose at 24 hour intervals): 500 mg (1 tablet).

Route of Administration: Oral

In Vitro Use Guide

Titrations of antibacterial activity were carried out by making twofold serial dilutions dilutions of plasma or serum and adding an equal volume (0.5 ml.) of a 10-5 dilution of an overnight culture of a strain of Escherichia coli which had been isolated from the peritoneal fluid of a patient with peritonitis and which was consistently sensitive to 0.30 mg. of sulfamethoxydiazine per 100 ml. of broth. Study of antibacterial titers showed that at 1: 64 the sulfonamide concentrations varied from 7 to 14 mg. per 100 ml
