Penicillin V Potassium-d5

Penicillin V-d₅ is intended for use as an internal standard for the quantification of penicillin V by GC- or LC-MS. Penicillin V is a β-lactam antibiotic that inhibits the growth of bacteria.^1,2,3 In vitro, penicillin V inhibits the growth of clinical isolates of Streptococci (MICs = 0.004-0.008 mg/L) and C. difficile (MICs = 1 to >256 mg/L).^1,2 Penicillin V also inhibits growth of S. aureus in vitro (MIC = 0.016 mg/L) and in vivo in a thigh model of infection in mice.³ It inhibits the growth of S. pyogenes in mice following one or two dose therapy with curative dose (CD₅₀) values of 0.207 and 0.031 mg, respectively.⁴ Penicillin V (100 mg/kg per day, p.o.) prevents experimental acute otitis media in rats when administered prior to infection by pneumococci.⁵ Formulations containing penicillin V have been used to treat bacterial infections of the skin, throat, ear, mouth, and respiratory tract.

Penicillin V-d5 (potassium) is the deuterium labeled Penicillin V Potassium[1]. Penicillin V Potassium (Phenoxymethylpenicillin potassium salt) is an orally active antibiotic. Penicillin V Potassium inhibits the growth of Streptococci, C. difficile and S. aureus. Penicillin V Potassium can be used for the research of otitis, sinusitis, pharyngitis and tonsillitis[2][3][4][5].
