Maximum plasma concentration (Cmax) of Valsartan [1] | ||||||||||||
End point description |
Cmax was defined as the observed maximum plasma concentration following drug administration [mass / volume]. It was determined using non-compartmental method using WinNonlin Pro (Version 5.2). Plasma concentrations of valsartan were determined using a validated LC-MS/MS method. The lower limit of quantification (LLOQ) of valsartan was 5 nanograms (ng)/millilitre (mL). The analysis was performed in pharmacokinetic analysis set (PAS) population, defined as all dosed subjects with evaluable PK data.

AEs were defined as any unfavorable and unintended diagnosis, symptom, sign (including an abnormal laboratory finding), syndrome or disease which either occurs during study, having been absent at baseline, or, if present at baseline, appears to worsen. Serious adverse events were any untoward medical occurrences that result in death, are life threatening, require (or prolong) hospitalization, cause persistent or significant disability/incapacity, result in congenital anomalies or birth defects, or are other conditions which in judgment of investigator represent significant hazards. AEs suspected to be related to study drug were determined by the investigator. The analysis was performed on safety population, defined as all subjects who received the study drug.
