DISPERMOX vs UNIPEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amoxicillin inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and disrupting 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.
Adults: 1 g (as amoxicillin 875 mg + clavulanate 125 mg) orally every 12 hours for 7-10 days.
500 mg to 2 g orally or intravenously every 4 to 6 hours; maximum 12 g/day IV for serious infections.

Terminal elimination half-life 1.5 hours; prolonged in renal impairment.
0.5-1 hour in normal renal function; prolonged to 7-10 hours in anuria or severe renal impairment.
Renal excretion 80% as unchanged drug, biliary/fecal 10%.
Renal: 70-90% unchanged via tubular secretion and glomerular filtration; biliary: minor (<10%); fecal: minimal.
