Metformin hydrochloride extended-release tablets, USP 500 mg and 750 mg tablets contain the inactive ingredients hypromellose, magnesium stearate, and polyvinyl pyrrolidone. Dissolution Method: Test 10 System Components and Performance - Metformin hydrochloride extended-release tablets, USP comprises a dual hydrophilic polymer matrix system. Metformin hydrochloride, USP is combined with a drug release controlling polymer to form an "inner" phase, which is then incorporated as discrete particles into an "external" phase of a second polymer. After administration, fluid from the gastrointestinal (GI) tract enters the tablet, causing the polymers to hydrate and swell. Drug is released slowly from the dosage form by a process of diffusion through the gel matrix that is essentially independent of pH. The hydrated polymer system is not rigid and is expected to be broken up by normal peristalsis in the GI tract. The biologically inert components of the tablet may occasionally remain intact during GI transit and will be eliminated in the feces as a soft, hydrated mass. metformin
