BACTOCILL IN PLASTIC CONTAINER vs UNIPEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bactericidal; inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity essential for peptidoglycan cross-linking.
Unipen (nafcillin) is a penicillinase-resistant penicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), blocking transpeptidation and autolysin inhibition.
1-2 g intravenously every 4 hours.
500 mg to 2 g orally or intravenously every 4 to 6 hours; maximum 12 g/day IV for serious infections.

30-60 minutes (mean 40 min) in adults with normal renal function; prolonged to 7-10 hours in anuria. Clinical context: dosing interval adjustment required in renal impairment.
0.5-1 hour in normal renal function; prolonged to 7-10 hours in anuria or severe renal impairment.
Primarily renal (60-70% unchanged by tubular secretion and glomerular filtration); biliary/fecal excretion accounts for <30%.
Renal: 70-90% unchanged via tubular secretion and glomerular filtration; biliary: minor (<10%); fecal: minimal.
