Final answer:
Metformin belongs to the drug class of biguanides and works to reduce glucose production in the liver, increase insulin sensitivity, and decrease glucose absorption from the intestines.
Step-by-step explanation:
The pharmacological action of metformin belongs to the drug class of biguanides. Biguanides are a type of antidiabetic medication that work by reducing glucose production in the liver, increasing the sensitivity of muscle and fat cells to insulin, and decreasing the absorption of glucose from the intestines.
Metformin is commonly prescribed to treat type 2 diabetes and it helps to control blood sugar levels. It does not stimulate the production of insulin by the pancreas, but rather helps to lower blood glucose levels by improving insulin sensitivity and reducing the amount of glucose produced by the liver.
This medication is typically taken orally and is one of the most commonly prescribed drugs for diabetes.
