Metformin Aurobindo (Metformin Hydrochloride)

Metformin Aurobindo belongs to the biguanide class and is used to manage disorders of glucose metabolism.

• Type 2 diabetes mellitus: lowers fasting and post‑prandial glucose levels to achieve glycaemic targets.
• Prediabetes (impaired fasting glucose): delays progression to overt diabetes by improving insulin sensitivity.
• Gestational diabetes mellitus (adjunct therapy): assists in controlling maternal blood glucose when diet alone is insufficient.

• Metformin reduces hepatic gluconeogenesis, decreases intestinal absorption of glucose, and enhances peripheral insulin sensitivity, leading to increased glucose uptake by muscle and adipose tissue. These actions collectively lower circulating blood‑glucose concentrations without stimulating insulin secretion.

Metformin Aurobindo may cause a range of adverse reactions, most of which are mild and reversible.

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Diarrhea: frequent loose stools, often transient.
• Abdominal discomfort: cramping or bloating.
• Metallic taste: transient alteration of taste perception.
• Loss of appetite: reduced desire to eat.
• Flatulence: increased intestinal gas.

Serious or Rare Side Effects

• Lactic acidosis: a rare but life‑threatening metabolic disturbance.
• Severe hypoglycaemia: usually when combined with insulin or sulfonylureas.
• Hepatic dysfunction: abnormal liver enzymes or hepatitis.
• Allergic reactions: rash, pruritus, or angio‑edema.
• Pancreatitis: inflammation of the pancreas.
• Skin reactions: severe rash or Stevens‑Johnson syndrome.

Metformin Aurobindo requires careful monitoring and patient education to minimise risks.

• Renal function: assess creatinine clearance before initiation and periodically thereafter.
• Hepatic function: evaluate liver enzymes in patients with known liver disease.
• Risk of lactic acidosis: avoid in patients with hypoxia, severe heart failure, or uncontrolled infection.
• Concomitant drugs: review medications that may impair renal clearance or increase metformin exposure.
• Elderly patients: start at lower dose and titrate cautiously.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Metformin Aurobindo can interact with several medicines, altering its efficacy or safety profile.

Major Interactions (Avoid)

• Alcohol: increases risk of lactic acidosis.
• Iodinated contrast agents: may precipitate acute kidney injury, requiring temporary discontinuation.
• Cimetidine: can raise metformin plasma concentrations.
• Rifampicin: may reduce metformin exposure.
• Nitrates: concurrent use can cause hypotension.

Moderate Interactions (Monitor Closely)

• Sulfonylureas: heightened risk of hypoglycaemia.
• Beta‑blockers: may mask hypoglycaemic symptoms.
• Diuretics: can affect renal function and metformin clearance.
• ACE inhibitors/ARBs: monitor renal function and electrolytes.
• NSAIDs: may impair renal perfusion, increasing metformin levels.
