Metformin Sr

Metformin Hydrochloride, the active ingredient in Metformin Sr, is a biguanide presented as an oral tablet for oral use. It is used to lower elevated blood glucose levels in adults with type 2 diabetes mellitus. GNH USA supplies Metformin Sr as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Metformin Sr belongs to the biguanide class and is employed in the management of disorders related to glucose metabolism. - Type 2 diabetes mellitus: improves glycaemic control by reducing hepatic glucose output and enhancing peripheral insulin sensitivity. - Impaired glucose tolerance: helps delay progression to overt diabetes when used as part of lifestyle intervention. - Polycystic ovary syndrome (off‑label): may improve insulin resistance and restore ovulatory function.

Metformin Sr may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Diarrhoea: loose stools, often early in therapy. - 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: rare but life‑threatening metabolic acidosis. - Severe skin reactions: such as Stevens‑Johnson syndrome. - Hypoglycaemia: when combined with other glucose‑lowering agents. - Hepatic failure: impaired liver function may exacerbate toxicity. - Renal impairment: accumulation leading to toxicity. - Vitamin B12 deficiency: long‑term use may reduce absorption.

Before initiating Metformin Sr, several safety considerations should be observed. - Renal function assessment: ensure adequate glomerular filtration rate before prescribing. - Hepatic function monitoring: evaluate liver enzymes to reduce lactic acidosis risk. - Lactic acidosis risk evaluation: avoid in patients with hypoxia, heart failure, or severe infection. - Elderly patient caution: start with lower doses and monitor tolerance. - Vitamin B12 status: consider periodic testing during long‑term therapy. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

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

Major Interactions (Avoid): - Iodinated contrast agents: may precipitate acute renal failure and lactic acidosis. - Cimetidine: can increase metformin plasma concentrations. - Alcohol excess: heightens risk of lactic acidosis.

Moderate Interactions (Monitor Closely): - Beta‑blockers: may mask hypoglycaemia symptoms. - Diuretics: can affect renal clearance of metformin. - ACE inhibitors or ARBs: monitor renal function and potassium levels. - Warfarin: may require INR monitoring. - Digoxin: observe for potential additive effects on renal function.
