What is the main action of metformin?
Metformin acts as a metabolic inhibitor and alters both whole-body and cellular energy metabolism. It is primarily used in patients with type 2 diabetes mellitus, and its main mechanism of action in this disease setting is inhibition of hepatic gluconeogenesis.
What are the most common side effects of metformin?
Nausea, vomiting, and diarrhea are some of the most common side effects people have when they first start taking metformin. These problems usually go away over time….The more common side effects of metformin include:
- heartburn.
- stomach pain.
- nausea or vomiting.
- bloating.
- gas.
- diarrhea.
- constipation.

What are effects of metformin?
Side Effects Nausea, vomiting, stomach upset, diarrhea, weakness, or a metallic taste in the mouth may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. If stomach symptoms return later (after taking the same dose for several days or weeks), tell your doctor right away.
What is the mechanism of metformin in the treatment of diabetes?
At the molecular level, metformin inhibits the mitochondrial respiratory chain in the liver, leading to activation of AMPK, enhancing insulin sensitivity (via effects on fat metabolism) and lowering cAMP, thus reducing the expression of gluconeogenic enzymes.
What body system is affected by metformin?
Metformin helps to control the amount of glucose (sugar) in your blood. It decreases the amount of glucose you absorb from your food and the amount of glucose made by your liver. Metformin also increases your body’s response to insulin, a natural substance that controls the amount of glucose in the blood.
What are the mechanisms of action of metformin?
Metformin has been shown to act via both AMP-activated protein kinase (AMPK)-dependent and AMPK-independent mechanisms; by inhibition of mitochondrial respiration but also perhaps by inhibition of mitochondrial glycerophosphate dehydrogenase, and a mechanism involving the lysosome.
What are the major clinical advantages of metformin?
Major clinical advantages of metformin include specific reduction of hepatic glucose output, with subsequent improvement of peripheral insulin sensitivity, and remarkable cardiovascular safety, but without increasing islet insulin secretion, inducing weight gain, or posing a risk of hypoglycemia.
How does metformin work in the liver and kidneys?
Metformin and the liver Metformin is traditionally thought to act on the liver to improve blood glucose levels and several lines of evidence support this.
What are the side effects of metformin associated lactic acidosis?
The onset of Metformin-associated lactic acidosis is often subtle, accompanied only by nonspecific symptoms such as malaise, myalgias, respiratory distress, somnolence, and abdominal pain.
