Trial overview
Official title: The effect of food on the pharmacokinetics of metformin given either as metformin hydrochloride SR 1000mg tablet or as a fixed dose combination of metformin hydrochloride SR 1000mg/glimepiride 2mg tablet in healthy Indian volunteers.
Trial description: Metformin hydrochloride in its immediate release (IR) form has been successfully used for decades in the treatment of type 2 diabetes; however the IR formulation may be associated with gastrointestinal side effects (especially nausea, diarrhea) in 20-30% patients, which can limit the tolerated dose, reduce adherence and result in discontinuation of therapy. Metformin hydrochloride extended release formulations have been developed to overcome these problems. In India, extended release formulations of metformin hydrochloride include metformin SR 1000mg tablet and combination of metformin hydrochloride SR 1000mg/glimepiride 2mg tablet. In the combination tablet, only metformin hydrochloride is in the extended release form. In view of the fact that extended release metformin hydrochloride is usually recommended with a meal, that food is known to affect the pharmacokinetic (PK) parameters of metformin and that there is a potential for dose dumping with extended release formulations that may lead to side effects similar to IR formulations, a study to estimate the magnitude of the food effect for these formulations in fed state compared to the fasting state is warranted. This study will be a randomized, single-center, open-label, single-dose, three-period, 6 sequence crossover study in 30 healthy adult volunteers to estimate the bioavailability of metformin from metformin hydrochloride 1000mg SR tablet given in fasting condition relative to metformin hydrochloride 1000mg SR tablet and a fixed dose combination of metformin hydrochloride 1000mg SR /glimepiride 2mg tablet, each given in fed condition. The safety and tolerability profile of metformin SR 1000mg tablet and metformin hydrochloride SR 1000mg/glimepiride 2mg tablet will also be evaluated in this study. The primary PK endpoints will be Cmax and AUC (0-∞). The secondary PK endpoints will include AUC (0-t), Tmax , T lag, Kel and t1/2. Safety endpoints will include vital signs, ECG, physical examination, clinical laboratory tests and adverse event reporting.

Accepts healthy volunteers
Yes
- 1.Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests, 12 lead ECG and chest-x-ray. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Medical Investigator agrees that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
- 2.Males between 18 and 50 years of age (both inclusive), who are willing to participate in the study and provide a written signed and dated informed consent.
- 1.A positive pre-study urine drug screen.
- 2.A positive test for HIV antibody.
