Metfromin Accord (Metformin Hydrochloride)

Metformin Hydrochloride is an oral antidiabetic agent indicated for disorders of glucose metabolism.

• Type 2 diabetes mellitus: improves glycaemic control by lowering fasting and post‑prandial blood glucose levels.

• Metformin Hydrochloride primarily inhibits hepatic gluconeogenesis, reducing the liver's production of glucose. It also enhances peripheral insulin sensitivity by increasing glucose uptake in muscle and adipose tissue and modestly decreases intestinal glucose absorption, collectively contributing to lower plasma glucose concentrations without stimulating insulin secretion.

Metformin Hydrochloride may cause a range of adverse reactions, from mild to severe.

Common Side Effects

• Nausea: transient upset stomach often occurring at treatment initiation.
• Diarrhoea: loose stools that may improve with continued use.
• Abdominal discomfort: cramping or bloating.
• Metallic taste: transient alteration in taste perception.

Serious or Rare Side Effects

• Lactic acidosis: a rare but life‑threatening accumulation of lactate.
• Severe skin reactions: such as Stevens‑Johnson syndrome.
• Hepatic failure: rare liver dysfunction requiring immediate medical attention.

Metfromin Accord requires careful monitoring and patient education.

• Renal function assessment: evaluate creatinine clearance before initiation and periodically thereafter.
• Hepatic impairment: avoid use in patients with significant liver disease.
• Contraindication in severe renal dysfunction: do not use if eGFR is below 30 mL/min/1.73 m².
• Alcohol consumption: limit intake as it may increase risk of lactic acidosis.
• Vitamin B12 monitoring: long‑term therapy may reduce B12 levels; consider periodic testing.
• Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture.

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

Major Interactions (Avoid)

• Iodinated contrast agents: may precipitate acute renal failure and increase lactic acidosis risk.
• Cimetidine: can raise metformin plasma concentrations.
• Alcohol: potentiates risk of lactic acidosis.

Moderate Interactions (Monitor Closely)

• Diuretics: may impair renal function, necessitating dose adjustment.
• Beta‑blockers: can mask hypoglycaemic symptoms.
• Oral contraceptives: may modestly increase metformin levels.
