title: Pharmacokinetics of the combined preparation of lisinopril and hydrochlorothiazide on Chinese healthy volunteers.
abstract: The aim of the present study, performed on two different groups of volunteers, is to characterize the pharmacokinetics of lisinopril/hydrochlorothiazide combined tablet. After administration of high, medium and low doses of lisinopril/hydrochlorothiazide combined tablets, AUC and C(max) of two compounds both increase significantly with increase of dose. Neither normalized AUC/Dose nor C(max)/Dose has significant difference between every two tested dose groups. The similar results can be observed as for the parameters of t(max). Lisinopril and hydrochlorothiazide are both eliminated with linear characteristics. After repeated administration of lisinopril/hydrochlorothiazide combined tablets, AUC, C(max) and C(min) of lisinopril in the steady state increase. AUC and C(min) increase significantly. As for hydrochlorothiazide, AUC, C(max), C(min), and t(max) also increase in steady state. AUC and C(min) increase significantly. Administered with the test medication, lisinopril has an fluctuation index (FI) value of 2.29 and reaches a relative steady concentration. But hydrochlorothiazide has an FI value of 4.09 with relatively large fluctuating concentrations.
