Pharmacokinetics of penciclovir injection in Chinese healthy volunteers / 中国临床药理学与治疗学

ABSTRACT

AIM:To study the pharmacokinetics of penciclovir injection in Chinese healthy volunteers.METHODS:10 healthy volunteers were infused a single dose of 10 mg/kg of penciclovir.The concentrations of penciclovir in plasma and urine were determined by HPLC-FLD.Pharmacokinetic parameters were conformed to a non-compartment model analyzed by WinNonLin program.RESULTS:The main pharmacokinetic parameters were as followsthe ke was(0.37?0.05)/h;the t1/2 was(1.91?0.26)h;the Cmax was(9.8?1.6)mg/L;the AUC0-t was(19.1?2.8)mg?L-1?h;the AUC0-∞ was(19.6?2.9)mg?L-1?h;the Vd was(1.4?0.4)L/kg;the CL was(0.52?0.08)L?h?kg-1.About 70% of penciclovir was excreted into urine within 12 h.CONCLUSION:Penciclovir is widely distributed and rapidly excreted,predominantly by the kidney.
