Active Ingredient:: Metformin Hydrochloride
Origin:: EU

Metforal (Metformin Hydrochloride)

Q: What is Metforal used for?

Metforal contains metformin hydrochloride and is prescribed to improve blood glucose control in adults with type 2 diabetes mellitus. It works by decreasing hepatic glucose production and increasing insulin sensitivity, helping patients achieve target glycaemic levels as part of a comprehensive diabetes management plan.

Q: How does metformin work in the body?

Metformin activates the enzyme AMP‑activated protein kinase (AMPK) in liver and muscle cells. This activation suppresses gluconeogenesis in the liver, reduces intestinal glucose absorption, and enhances peripheral uptake of glucose, thereby lowering fasting and post‑prandial blood sugar concentrations without directly stimulating insulin secretion.

Q: What is the usual dose of Metforal?

The appropriate dose of Metforal is determined by the prescribing healthcare professional based on individual patient factors such as renal function, glycaemic targets, and tolerability. Dosage adjustments are made during treatment to achieve optimal blood glucose control while minimising adverse effects.

Q: Is Metforal safe during pregnancy or breastfeeding?

The safety of Metforal in pregnancy and lactation has not been definitively established. It is generally advised to avoid metformin during the first trimester unless the benefits outweigh potential risks, and to discuss continuation during breastfeeding with a qualified healthcare provider.

Q: How do I order Metforal from GNH India?

To place an order, submit an enquiry on the Metforal product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Q: How does Metforal compare with other antidiabetic drugs?

Metforal (metformin) is a first‑line therapy for type 2 diabetes due to its efficacy, low risk of hypoglycaemia and favourable impact on weight. Compared with sulfonylureas, it does not cause insulin release, and unlike insulin, it is administered orally and does not require injection.

Q: What are the recommended storage conditions for Metforal?

Metforal should be stored at room temperature, below 25 °C, in its original packaging to protect it from moisture and light. Keep the product out of reach of children and do not use it after the expiry date printed on the label.

Q: How is Metforal administered?

Metforal is taken orally, usually with meals to reduce gastrointestinal discomfort. Tablets should be swallowed whole with a glass of water and not crushed or chewed, unless the prescribing information specifies an alternative method.

Q: What are the most serious risks associated with Metforal?

The most serious risk is lactic acidosis, a rare but potentially fatal condition characterized by rapid breathing, muscle pain, and abdominal discomfort. Other serious concerns include severe skin reactions and hepatic dysfunction. Patients should seek immediate medical attention if they experience any of these symptoms.

Q: Who should not use Metforal?

Metforal is contraindicated in patients with severe renal impairment (eGFR <30 mL/min/1.73 m²), acute or chronic metabolic acidosis, known hypersensitivity to metformin, and those undergoing radiologic procedures with iodinated contrast unless the drug is discontinued beforehand.

Metformin, the active ingredient in Metforal, is a Biguanide presented as an oral tablet for oral use. It is used to improve glycaemic control in adults with type 2 diabetes mellitus.

GNH India supplies Metforal as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Indications & Clinical Uses

Metforal belongs to the biguanide class and is indicated for disorders of glucose metabolism.

Type 2 diabetes mellitus: improves blood glucose control by lowering hepatic glucose output and enhancing peripheral insulin sensitivity.

How It Works

Metformin reduces hepatic gluconeogenesis and increases peripheral glucose uptake by activating AMP‑activated protein kinase (AMPK). This leads to decreased liver glucose production, improved insulin sensitivity in muscle and adipose tissue, and modest weight loss, collectively contributing to lower plasma glucose levels.

Side Effects

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

Common Side Effects

Nausea: mild to moderate gastrointestinal upset.
Diarrhea: loose stools, often early in therapy.
Abdominal discomfort: cramping or pain.
Metallic taste: transient alteration of taste perception.
Loss of appetite: reduced desire to eat.
Weight loss: modest reduction in body weight.

Serious or Rare Side Effects

Lactic acidosis: rare but potentially fatal metabolic acidosis.
Severe skin reactions: such as Stevens‑Johnson syndrome.
Hepatic dysfunction: elevated liver enzymes.
Vitamin B12 deficiency: long‑term use may reduce absorption.
Pancreatitis: inflammation of the pancreas.
Hypoglycaemia: usually when combined with other antidiabetics.

Precautions & Warnings

Metforal requires careful monitoring and patient education to minimise risks.

Renal function assessment: avoid use in severe renal impairment (eGFR <30 mL/min/1.73 m²).
Hepatic function monitoring: contraindicated in acute liver disease.
Lactic acidosis risk: discontinue before radiologic contrast studies.
Alcohol consumption: limit intake to reduce acidosis risk.
Elderly patients: start at lower dose and monitor tolerance.
Store at room temperature: keep in original container, protect from moisture and heat.

Avoid Interactions

Metforal can interact with several medicines, altering its efficacy or safety.

Major Interactions (Avoid)

Iodinated contrast agents: increase risk of lactic acidosis; withhold metformin before and after the procedure.
Cimetidine: may raise metformin plasma concentrations.
Acute heart failure: can precipitate renal dysfunction and lactic acidosis.

Moderate Interactions (Monitor Closely)

Beta‑blockers: may mask hypoglycaemia symptoms.
Diuretics: can affect renal clearance of metformin.
ACE inhibitors/ARBs: monitor renal function and potassium.
Other antidiabetic agents: risk of additive hypoglycaemia.
Corticosteroids: may raise blood glucose, requiring dose adjustment.
