DYNAPEN vs GEOCILLIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dynapen (dicloxacillin) is a penicillinase-resistant penicillin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
Geocillin (carbenicillin indanyl sodium) is a penicillin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death. It exhibits bactericidal activity against susceptible gram-negative and gram-positive bacteria.
250-500 mg orally every 6 hours for skin and soft tissue infections; up to 500 mg every 6 hours for respiratory tract infections.
250-500 mg orally every 6 hours.

0.5-1 hour in normal renal function; prolonged to 7-10 hours in anuria.
1.2 hours (normal renal function); prolonged to 7-10 hours in severe renal impairment (CrCl <10 mL/min).
Renal: 60-80% as unchanged drug via glomerular filtration and tubular secretion; biliary/fecal: <10%.
Primarily renal (70-80% unchanged via tubular secretion and glomerular filtration); minor biliary/fecal (<5%).
