Sulfamethizole is a sulfonamide antibiotic. The sulfonamides are synthetic bacteriostatic antibiotics with a wide spectrum against most gram-positive and many gram-negative organisms. However, many strains of an individual species may be resistant. Sulfonamides inhibit multiplication of bacteria by acting as competitive inhibitors of p-amino...

Mechanism of Action: Sulfamethizole is a competitive inhibitor of bacterial enzyme dihydropteroate synthetase. The normal para-aminobenzoic acid (PABA) substrate is prevented from binding. The inhibited reaction is necessary in these organisms for the synthesis of folic acid.
Absorption: Rapidly absorbed.
Protein binding: 98-99%
Biotransformation: Hepatic.
Half Life: 3-8 hours
Affected organisms: Enteric bacteria and other eubacteria
Drug interaction:
