Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Penicillin G is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), transpeptidases that catalyze the final transpeptidation step of peptidoglycan cross-linking, leading to cell lysis.
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.
800 mg orally every 6 to 8 hours; maximum 4 g per day.
250-500 mg orally every 6-8 hours for 10 days for streptococcal pharyngitis; 250-500 mg orally every 6 hours for pneumococcal infections.
