Bioequivalence Study of Two Formulations of 10 mg Lisinopril Tablet Under Fasting Condition

Bioequivalence Study of 10 mg Lisinopril Tablets (Lisinopril 10 mg) Produced by PT Dexa Medica in Comparison With The Innovator Tablets (Zestril® 10 mg, PT Boehringer Ingelheim Indonesia, Indonesia, Under License From Astra Zeneca UK Ltd.)

The present study was conducted to find out whether the bioavailability of 10 mg lisinopril tablets produced by PT Dexa Medica was equivalent to the tablets produced by the innovator (Zestril® 10 mg, PT Boehringer Ingelheim Indonesia, Indonesia, under license from Astra Zeneca UK Ltd.)

Study Overview

• Status: Completed
• Conditions: Healthy
• Intervention / Treatment: Drug: Lisinopril 10 mg tablets of PT Dexa Medica; Drug: Lisinopril 10 mg tablets of PT Boehringer Ingelheim Indonesia

Detailed Description

This was a randomized, single-blind, two-period, two-sequence, cross-over study under fasting condition. The participating subjects were required to have an overnight fast and in the next morning were given orally one tablet of the test drug (Lisinopril 10 mg, produced by PT Dexa Medica) or one tablet of the reference drug (Zestril® 10 mg, PT Boehringer Ingelheim Indonesia, Indonesia, under license from Astra Zeneca UK Ltd.).

Blood samples were drawn immediately before taking the drug (control), and at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 16, 24, 36, and 48 hours after drug administration. Seven days after the first drug administration (washout period), the procedure was repeated using the alternate drug.

The pharmacokinetic parameters, including AUCt, AUCinf, Cmax, t max, and t1/2, were determined from plasma concentrations of lisinopril, using liquid chromatography with tandem mass spectrometry detection (LC-MS/MS) method.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Area under the plasma concentration-time curve from time zero to the last observed quantifiable concentration (AUCt) of lisinopril	Relative bioavailability (primarily measured by AUCt and AUCinf) between two lisinopril 10 mg tablet formulations (test and reference formulations) was assessed under fasting condition. AUCt was determined from plasma concentration of lisinopril.	48 hours
Area under the plasma concentration-time curve from time zero to infinity (AUCinf) of lisinopril	Relative bioavailability (primarily measured by AUCt and AUCinf) between two lisinopril 10 mg tablet formulations (test and reference formulations) was assessed under fasting condition. AUCinf was determined from plasma concentration of lisinopril.	48 hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The peak plasma concentration (Cmax) of lisinopril	Relative bioavailability (secondarily measured by Cmax) between two lisinopril 10 mg tablet formulations (test and reference formulations) was assessed under fasting condition. Cmax was determined from plasma concentration of lisinopril.	48 hours
Time needed to achieve the peak plasma concentration (t max) of lisinopril	Relative bioavailability (secondarily measured by t max) between two lisinopril 10 mg tablet formulations (test and reference formulations) was assessed under fasting condition. t max was determined from plasma concentration of lisinopril.	48 hours
The elimination half-life (t1/2) of lisinopril	Relative bioavailability (secondarily measured by t1/2) between two lisinopril 10 mg tablet formulations (test and reference formulations) was assessed under fasting condition. t1/2 was determined from plasma concentration of lisinopril.	48 hours
