Bioequivalence Study of Two Formulations of Perindopril 4 mg Tablet Under Fasting Condition

Condition(s) targeted: Healthy

Intervention: Perindopril 4 mg tablets of PT Dexa Medica (Drug); Perindopril 4 mg tablets of Servier (Drug)

Phase: N/A

Status: Completed

Sponsored by: Dexa Medica Group

Official(s) and/or principal investigator(s):
Danang A Yunaidi, MD, Principal Investigator, Affiliation: PT Equilab International

The objective of this study was to find out whether the bioavailability of PT Dexa Medica's formulation of 4 mg perindopril tert-butylamine tablets was equivalent to that of the innovator's product (Prexum® 4 mg, Servier).

Official title: Bioequivalence Study of 4 mg Perindopril Tablets Produced by PT Dexa Medica in Comparison With the Reference Tablets (Prexum® 4 mg, Servier)Under Fasting Condition

Study design: Allocation: Randomized, Endpoint Classification: Bio-equivalence Study, Intervention Model: Crossover Assignment, Masking: Single Blind (Investigator), Primary Purpose: Treatment

Primary outcome:

Area under concentration-time curve (AUC)of perindopril parent compound

Area under concentration-time curve (AUC)of perindoprilat

Secondary outcome:

Peak plasma concentration (Cmax)of perindopril parent compound

Peak plasma concentration (Cmax)of perindoprilat

Time to achieve the peak plasma concentration (tmax)of perindopril parent compound

Time to achieve the peak plasma concentration (tmax)of perindoprilat

Elimination half-life (t1/2)of perindopril parent compound

Elimination half-life (t1/2)of perindoprilat

Detailed description: The participating subjects were required to have an overnight fast and in the next morning were given orally one tablet of the test drug (Perindopril 4 mg tablets of PT Dexa Medica) or one tablet of the reference drug (Prexum® 4 mg, Servier). Blood samples were drawn immediately before taking the drug (control), and at 20, 40 minutes, and 1, 1. 5, 2, 3, 4, 6, 8, 12, 24, 48, 96, 144, 192 hours after drug administration. Three weeks 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 based on the concentrations of the perindopril parent compound and the metabolite perindoprilat, using high-performance liquid chromatography method with tandem mass spectrometry detector (LC-MS/MS).
