COACTIN vs PEDIAZOLE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Coactin (mecillinam) is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding protein 2 (PBP2) in gram-negative bacteria, leading to the formation of spheroplasts and cell lysis.
Pediazole is a combination of erythromycin (a macrolide antibiotic that binds to the 50S ribosomal subunit, inhibiting bacterial protein synthesis) and sulfisoxazole (a sulfonamide that inhibits dihydropteroate synthase, blocking folic acid synthesis).
400 mg orally every 6-8 hours with a full glass of water.
Adults: 1 mg/kg intravenously every 6 hours.

Terminal elimination half-life: 1.0-1.5 hours in adults with normal renal function; prolonged to 2-6 hours in renal impairment; clinically requires frequent dosing or dose adjustment in renal failure.
Terminal half-life is approximately 6-8 hours in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment.
Renal: approximately 70-80% as unchanged drug via glomerular filtration and tubular secretion; biliary/fecal: less than 10% as metabolites and unchanged drug.
Renal excretion of unchanged drug accounts for approximately 70-80% of the dose; biliary/fecal elimination is minor (<10%).
