Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dicloxacillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby inhibiting transpeptidation and leading to cell lysis. It is resistant to penicillinase-producing organisms.
Penicillin G procaine is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
125-500 mg orally every 6 hours
600,000 units intramuscularly once daily; or 1.2 million units intramuscularly every 12 hours for severe infections.

Terminal elimination half-life: 0.6-0.8 hours in adults with normal renal function; prolonged to 1-2 hours in neonates, elderly, or severe renal impairment.
0.5-1 hour in adults with normal renal function; prolonged to 7-10 hours in end-stage renal disease
Primarily renal: ~60-85% unchanged via glomerular filtration and tubular secretion; ~10% hepatobiliary (bile) and fecal; minor metabolism to penicilloic acid.
