Metformin (Glucophage) is an antidiabetic medicine that improves glycemic control by reducing hepatic glucose production and increasing insulin sensitivity.
It is used for the management of type 2 Diabetes Mellitus as an adjunct to diet and exercise. It is considered to be the preferred initial treatment if tolerated and no contraindications to treatment exist.
-
It is also used as an off-label treatment in adults in the following conditions:
-
Antipsychotic-induced weight gain
-
Prevention of Type 2 Diabetes Mellitus
-
Treatment of Gestational Diabetes Mellitus
-
Polycystic ovary syndrome (PCOS)
-
For the treatment of oligomenorrhea due to PCOS
-
For the prevention of ovarian hyperstimulation syndrome (OHSS) in females with PCOS.
-

- Patients with an existing impairment:
-
eGFR of less than 30 mL/minute/1.73 m² :
- Its use is contraindicated.
Metformin (Glucophage) Dose in Liver Disease:

Warnings & Precautions
Lactic acidosis: [US Boxed Warning]:
- Metformin-induced lactic acidosis can be life-threatening. It can cause death, hypothermia, hypotension, as well as cardiac bradyarrhythmias.
- Non-specific symptoms of lactic acidosis include malaise, myalgias, and somnolence.
- It is characterized by high blood lactate levels (more than 5 mmol/L), anion gaps metabolic acidosis, and increased lactate: pyruvate ratio. Plasma metformin levels are more than 5 mg/ml.
- These patients are at high risk for developing lactic acidosis:
- Patients with severe renal impairment
- Use of other drugs, such as topiramate or Acetazolamide, in conjunction with certain drugs
- Over 65
- Radiocontrast study of patients
- Major surgeries and diagnostic procedures are performed on patients undergoing major surgery.
- Hypoxic states, such as heart failure, can be hypoxic.
- Hepatic impairment
- Alcohol intake that is excessive
- Patients with lactic acidosis must stop treatment immediately. They may need hemodialysis.
Vitamin B - 12 concentrations:
- Metformin's long-term use is linked to vitamin B-12 deficiency.
- Patients with anemia or peripheral neuropathy should have their serum levels of vitamin A 12 levels monitored regularly.
Heart failure:
- Patients suffering from unstable heart failure may be at high risk for lactic acidosis secondary hypoperfusion.
- It can be used for patients with stable heart disease and is associated with reduced hospital admissions and mortality.
Hepatic impairment:
- Metformin may be recommended for patients with mild to moderate liver dysfunction. However, individuals with advanced liver disease or unstable liver function may need to be careful.
- Patients with advanced liver disease should avoid it.
Renal impairment:
- Metformin is excreted through the kidneys.
- Before initiating treatment, patients should have their renal function checked and again periodically thereafter.
- Patients with a lower eGFR than 30 ml/min/1.73m2 should not use it.
- Patients with an eGFR of 30 to 45 ml/min or less should have their dose reduced.
- Patients suffering from acute renal dysfunction or dehydration should not use it.
Stress-related states:
- Patients suffering from acute stress such as trauma, fever, infection, or surgery should not use insulin. Instead, they should be prescribed insulin.

How to administer Metformin?
To reduce gastrointestinal side effects, it is taken orally along with food. Extended-release tablets must be taken whole. You should not chew, crush, or chew the extended-release tablets.
Mechanism of action of Metformin:
Metformin improves the glycemic control of patients with type 2 Diabetes Mellitus through the following mechanisms:
- It reduces the production of hepatic glucose.
- It decreases glucose absorption from the intestines.
- Metformin increases insulin sensitivity by increasing glucose uptake in peripheral tissues.
The onset of action:
- Metformin can take up to two weeks. The maximum effect can last up to 2 weeks. The drug is bound to proteins in very small quantities.
Bioavailability of Metformin:
- It has a bioavailability of 50% to 60% when administered in the fasting state.
Metabolism:
- It is not metabolized by the liver.
- 90% of the drug is excreted in urine as unchanged in the urine.
The half-life of metformin:
- It has an eliminating half-life between 4 and 9 hours, and blood for 17.6 hours.
The time to reach peak serum concentration:
- The time to achieve peak serum concentration for the immediate-release tablet is 2 - 3 hours, while the extended-release tablet takes 7 hours. This ranges from 4 – 8 hours.
