Bioavailability of Duloxetine 60 mg With Regards to Reference Product in Feeding Conditions

Bioavailability of a Formulation of Duloxetine 60 mg Enteric Coated Granules With Regards to Reference Product in Feeding Conditions

This Study will investigate the bioavailability in fasting subjects of 1 capsule formulation containing Duloxetine 60 mg. The Study will be performed at a single site with 36 subjects.Participants will take 1 capsule of the test product and reference product in 2 periods and 2 sequences (either test after reference or reference after test). There will be a washout of at least 14 days between each study period.

Study Overview

• Status: Completed
• Conditions: Bioequivalence
• Intervention / Treatment: Drug: Duloxetine 60mg Test Drug Enteric Coated Granules; Drug: Duloxetine 60mg Reference Product Enteric Coated Granules

Detailed Description

The primary objective of the study is to investigate the relative bioavailability of Duloxetine of 1 capsule formulation with Duloxetine 60 mg under feeding conditions to demonstrate bioequivalence of both formulations in terms of rate and extent of absorption:

• Test Product: Product manufactured by Laboratorios Andrómaco S.A.
• Reference Product: Cymbalta[Trademark], product of Eli Lilly, Puerto Rico.

The 90% confidence intervals for the intra-subject coefficient of variation (Test versus Reference Product) for the main pharmacokinetic parameters area under the plasma concentrationtime curve from time zero to time t (AUC0-t) and from time zero to 72 hours (AUC0-72), and maximum plasma concentration (Cmax) for total Duloxetine will be determined.

Participants will be confined in the study site for approximately 25,5 hours during each study period (for 10 hours pre-dosing and for 15,5 hours post dosing) during which pharmacokinetic (PK) blood samples will be obtained. 17 blood samples will be taken up to 24 hours after the administration in each period. Participants will return to the site to provide additional blood samples at 48 h, and 72 h postdose.The washout period between the two study periods will be at least 14 days.

The samples from each participant will be analyzed with 2 methods of high performance liquid chromatography-tandem mass spectrometry bioanalytical assays to quantify total Duloxetine in plasma.

The safety objective is to evaluate the tolerability of both formulations in subjects by collecting adverse events.
