Study Overview
=================
Brief Summary
-----------------
This study was designed to assess the bioequivalence of Progesterone 200 mg Soft Capsule (JSC Farmak, Ukraine) versus Utrogestan® 200 mg Soft Capsule (Manufacturer: Cyndea Pharma, S.L., Spain, MAH: Laboratoires Besins International, France) after a single Vaginal dose in healthy female subjects under fasting conditions.

Detailed Description
-----------------
An open-label, randomized, single dose, two-treatment, four-period, two-sequence, fully replicated crossover bioequivalence study with a washout period of 7 days in healthy female subjects under fasting conditions.Mode of administration:Intravaginally, the capsule introduced deeply into the vagina while lying down.During each period 25 blood samples were drawn 5 mL at (-1.00,-0.50,-0.137), before dosing and at 0.50, 1.00, 1.50, 2.00,2.50, 3.00, 3.50, 4.00, 4.50, 5.00, 5.50, 6.00, 7.00, 8.00, 9.00, 10.00, 12.00, 16.00, 24.00,36.00, 48.00, and 72.00 hours after dosing.
