Study Description

Brief Summary

This study was designed to compare the bioavailability of the Test Product Metformin 1000 mg Prolonged Release Tablets (JSC Farmak, Ukraine) and Reference Product Glucophage® XR 1000 mg Prolonged Release Tablets (Merck Serono Ltd, UK) in healthy male and female volunteers under fed conditions.

Condition or Disease	Intervention/Treatment	Phase
Pharmacokinetics	Drug: Metformin 1000 mg Prolonged Release Tablets (JSC Farmak, Ukraine) Drug: Glucophage® XR 1000 mg Prolonged Release Tablets	Phase 1

Detailed Description

An Open, Comparative, Randomized, Crossover Clinical Trial to Evaluate the Bioequivalence of Single Doses of Test Product Metformin 1000 mg Prolonged Release Tablets (JSC Farmak, Ukraine) and Reference Product Glucophage® XR 1000 mg Prolonged Release Tablets (Merck Serono Ltd, UK) in Healthy, Adult Male and Female Subjects Under Fed Conditions.

Outcome Measures

Primary Outcome Measures

Cmax [up to 36 hours post-administration]
maximum plasma concentration observed (Cmax)
AUC0-t [up to 36 hours post-administration]
Area under the plasma concentration versus time curve calculated by the trapezoidal rule from sampling time zero to sampling time of the last measurable plasma concentration (AUC0-t)

Secondary Outcome Measures

AUC0-∞ [up to 36 hours post-administration]
Area under the plasma concentration versus time curve from time zero to infinity (AUC0-∞)
tmax [up to 36 hours post-administration]
The time of the maximum plasma concentration (tmax).
λz [up to 36 hours post-administration]
Apparent first-order elimination (λz)
t1/2 [up to 36 hours post-administration]
the elimination or terminal half-life (t1/2)
AUCres [up to 36 hours post-administration]
Residual area AUCres = 100 (AUC0-∞ - AUC0-t) / AUC0-∞ [%]
