SYSTEM COMPONENTS AND PERFORMANCE- Metformin hydrochloride extended -
release tablets
comprises a hydrophilic polymer matrix system. Metformin hydrochloride
is combined with a drug
release controlling polymers to form a monophasic matrix system. 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. T
