Infomet 500mg Tablet SR contains Metformin hydrochloride, a biguanide class oral antihyperglycemic agent used primarily in the management of type 2 diabetes mellitus. It functions by decreasing hepatic glucose production, reducing intestinal absorption of glucose, and improving insulin sensitivity by enhancing peripheral glucose uptake and utilization. This sustained-release formulation ensures a gradual release of the active ingredient, promoting better gastrointestinal tolerability and improved patient compliance through once or twice-daily dosing. Infomet 500mg Tablet SR is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes, particularly in overweight patients and those whose hyperglycemia is inadequately controlled by diet alone. It may be used as monotherapy or in combination with other antidiabetic agents, including insulin. Common side effects include gastrointestinal disturbances such as nausea, diarrhea, and abdominal discomfort, which often diminish with continued use. Lactic acidosis, although rare, is a serious adverse effect requiring immediate medical attention. Contraindications include renal impairment, acute or chronic metabolic acidosis, and conditions predisposing to hypoxia. Regular monitoring of renal function and glycemic parameters is recommended during therapy to ensure safety and efficacy.
