In Vitro Penicillin V (0.002-8.0 mg/L) inhibits the growth of Streptococci, with the minimum inhibitory concentrations (MICs) of 0.004-0.008 mg/L[2]. Penicillin V (0.002-8.0 mg/L) shows antibacterial activity for Clostridium difficile with an MIC50 value of 4.0 mg/L and an MIC90 value of 8.0 mg/L[3]. Penicillin V (0.004-0.063 mg/L; 18 h) inhibits the growth of Staphylococcus aureus, with an MIC value of 0.016 mg/L[4].
In Vivo Penicillin V (0.063-0.25 mg/kg; s.c.) inhibits the outgrowth of S. aureus in mice thigh muscle[4]. Penicillin V (2 mg/kg; s.c.) exhibits the plasma half-life (61 min) and mean AUC (0.47 mg/L·h)[4]. Penicillin V (100 mg/kg; p.o. once daily for 5 d) avoids the fulminant infection of acute purulent otitis media (AOM) in rats[5]. Animal Model: Specific pathogen free (SPF) male Swiss mice (20-25 g) are inoculated S. aureus[4] Dosage: 0.063, 0.13, 0.25 mg/kg Administration: S.c. Result: Decreased the number of CFU (1.34×107 counts/mL) compared to controls (3.5×107 counts/mL) at the dose of 0.25 mg/kg.
