Metabet SR is a sustained-release medication primarily used in the management of type 2 diabetes mellitus. It contains Metformin Hydrochloride as its active ingredient, which belongs to a class of drugs known as biguanides. Metabet SR works by improving the sensitivity of body tissues to insulin, thereby facilitating the uptake of glucose by the cells and lowering blood sugar levels. It also decreases the amount of glucose produced by the liver. The sustained-release formulation of Metabet SR is designed to release the drug slowly over time, which helps in maintaining a steady level of the medication in the bloodstream, potentially reducing side effects and improving patient compliance with the treatment regimen. It is important for patients to follow their healthcare provider's instructions regarding diet, exercise, and medication for optimal control of their diabetes.
