UTICILLIN VK vs V-CILLIN K
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Uticillin VK (penicillin V potassium) is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) in the bacterial cytoplasmic membrane, thereby inhibiting transpeptidation and autolysin inhibition, leading to cell lysis and death.
Penicillin V exerts bactericidal activity by inhibiting bacterial cell wall synthesis through binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity, and disrupting peptidoglycan cross-linking.
250-500 mg orally every 6-8 hours for 10 days for streptococcal pharyngitis; 250-500 mg orally every 6 hours for pneumococcal infections.
250-500 mg orally every 6 hours for mild to moderate infections; 500 mg orally every 6 hours for severe infections.

0.5-1.0 hour (prolonged in renal impairment; e.g., up to 10 hours in anuria)
0.5–1 hour (normal renal function); prolonged to 2–6 hours in renal impairment.
Renal: 70-80% unchanged via tubular secretion and glomerular filtration; biliary/fecal: minor (about 10%)
Renal: 60-90% unchanged via tubular secretion and glomerular filtration; minor biliary/fecal: <10%.
