Glimezit (Metformin Hydrochloride)

Glimezit is indicated for the management of elevated blood glucose in adults with type 2 diabetes mellitus, typically as part of a comprehensive treatment plan that includes diet and exercise.

• As monotherapy in patients who have not achieved glycemic control with diet and exercise alone.
• In combination with other oral antidiabetic agents such as sulfonylureas, DPP‑4 inhibitors, or SGLT2 inhibitors.
• As an adjunct to insulin therapy when additional glucose lowering is required.
• For patients with overweight or obesity where metformin’s weight‑neutral profile is advantageous.
• To improve insulin sensitivity and reduce hepatic glucose output in the long‑term management of type 2 diabetes.

The safety profile of Glimezit reflects the typical adverse event pattern of metformin, with most reactions being mild and transient.

Common

• Nausea, abdominal discomfort, or diarrhea, which usually improve with dose titration.
• A persistent metallic or bitter taste in the mouth, often reported during the first weeks of therapy.
• Reduced appetite leading to mild, gradual weight loss in some patients.
• Decreased absorption of vitamin B12 over months, potentially resulting in mild anemia if not monitored.

Serious

• Lactic acidosis, a rare but serious metabolic disturbance characterized by elevated blood lactate levels and acidosis, requiring immediate medical attention.
• Severe hypoglycemia, particularly when Glimezit is used together with insulin or insulin‑secretagogue agents, manifesting as confusion, sweating, or loss of consciousness.
• Acute renal impairment or worsening kidney function, which can increase metformin accumulation and risk of toxicity.

Before initiating Glimezit, clinicians should evaluate patient history and monitor specific clinical parameters to minimize risks.

• Assess renal function; avoid use in patients with severe renal impairment (eGFR <30 mL/min/1.73 m²).
• Review hepatic status, as liver disease may increase the risk of lactic acidosis.
• Evaluate for conditions that predispose to hypoxia (e.g., heart failure, recent myocardial infarction, severe infection).
• Use caution in elderly patients due to higher susceptibility to renal decline and dehydration.
• Discontinue temporarily before radiologic procedures that use iodinated contrast agents.
• Monitor vitamin B12 levels periodically during long‑term therapy.
• Counsel patients on recognizing signs of lactic acidosis, such as unexplained muscle pain or rapid breathing.

Glimezit may interact with other medicines, affecting its efficacy or safety; certain combinations should be avoided while others require careful monitoring.

Avoid

• Iodinated contrast media used for imaging studies, which can precipitate acute kidney injury and increase metformin accumulation.
• Cimetidine, as it can reduce renal clearance of metformin and raise plasma concentrations.
• Alcohol excess, which may potentiate the risk of lactic acidosis.

Use with caution

• Insulin or insulin‑secretagogue agents (e.g., sulfonylureas, meglitinides) because of an increased risk of hypoglycemia.
• Diuretics, especially loop or thiazide types, which may affect hydration status and renal function.
• Corticosteroids, which can raise blood glucose and may require dose adjustments of Glimezit.
• ACE inhibitors or ARBs, which can influence renal function and necessitate periodic monitoring of kidney parameters.
