Category C

SULFOSE

Sulfonamide Antibiotic

Category C

Head-to-Head

Clinical Matrix

Mechanism of Action

Competitive inhibitor of dihydropteroate synthase, blocking para-aminobenzoic acid (PABA) incorporation into dihydropteroic acid, thereby inhibiting bacterial folic acid synthesis.

Sulfonamide antibiotic; inhibits bacterial dihydropteroate synthase, blocking folate synthesis and bacterial growth.

Clinical Dosing

2-4 g orally initially, then 2-4 g every 4-6 hours, not to exceed 12 g/day; intravenous: 4-8 g/day in divided doses every 6-8 hours.

Meningococcal meningitis: 100 mg/kg/day intravenously in 4 divided doses (maximum 6 g/day). For other infections: 2-4 g/day IV/IM in 3-4 divided doses.

Direct Interaction

None Documented

Half-Life

Terminal elimination half-life: 7-12 hours; prolonged in renal impairment (up to 24-48 hours).
