Keymet

Metformin Hydrochloride, the active ingredient in Keymet, 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 Keymet as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Keymet (Metformin Hydrochloride) belongs to the biguanide class and is employed in disorders of glucose metabolism. - Type 2 diabetes mellitus: improves glycaemic control by reducing hepatic glucose output and enhancing peripheral insulin sensitivity. - Prediabetes: helps delay progression to diabetes by lowering fasting plasma glucose. - Polycystic ovary syndrome: reduces insulin resistance, which can improve ovulatory function and hormonal balance.

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

Common Side Effects: - Gastrointestinal upset: nausea, abdominal discomfort, or loss of appetite. - Diarrhea: loose stools occurring especially after treatment initiation. - Metallic taste: transient alteration in taste perception.

Serious or Rare Side Effects: - Lactic acidosis: a rare but life‑threatening accumulation of lactate, particularly in patients with renal impairment. - Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Vitamin B12 deficiency: may develop with long‑term therapy, leading to neuropathy or anemia.

Metformin Hydrochloride requires careful monitoring and patient education to minimise risks. - Renal function assessment: avoid use in patients with severe renal impairment (eGFR <30 mL/min/1.73 m²). - Hepatic function evaluation: contraindicated in acute or chronic liver disease due to lactic acidosis risk. - Lactic acidosis risk: discontinue before any radiographic contrast studies that may affect kidney function. - Elderly dosing: consider lower starting dose and titrate slowly. - Drug‑induced vitamin B12 deficiency: monitor levels during prolonged therapy. - Store at room temperature: keep in the original container, protect from moisture and heat.

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

Major Interactions (Avoid): - Iodinated contrast agents: may precipitate acute renal failure and increase lactic acidosis risk. - Cimetidine: can raise metformin plasma concentrations, enhancing toxicity. - Alcohol excess: potentiates lactic acidosis, especially in patients with hepatic disease.

Moderate Interactions (Monitor Closely): - Diuretics: may affect renal clearance, requiring dose adjustment. - Beta‑blockers: can mask hypoglycaemic symptoms, though metformin rarely causes hypoglycaemia. - ACE inhibitors or ARBs: combined use may impact renal function, necessitating monitoring. - NSAIDs: may reduce renal perfusion, increasing metformin accumulation.
