Glipizide vs Metformin: Difference and Comparison

Type 2 diabetes is a chronic disease affecting the body’s blood sugar level working. It is a widespread disease with symptoms like frequent urination, fatigue, blurred vision, increased thirst and hunger, etc.

There are cases when the patient doesn’t feel the symptoms. Glipizide and Metformin are type-2 diabetes-treating drugs.

Key Takeaways

  1. Glipizide stimulates the pancreas to release more insulin, lowering blood sugar levels.
  2. Metformin reduces glucose production in the liver and improves insulin sensitivity.
  3. Both medications treat type 2 diabetes, but metformin is the first-line treatment.

Glipizide vs Metformin

Glipizide is a sulfonylurea medication that stimulates the pancreas to produce more insulin, which helps to lower blood sugar levels. It is taken once or twice a day with meals. Metformin is a biguanide medication that reduces glucose production in the liver and improves insulin sensitivity in the body.

Glipizide vs Metformin

Glipizide is a short-acting and rapid drug that is to be taken orally. It is used for the treatment of type-2 diabetes in adults and is a drug that belongs to the sulfonylureas group.

It helps in lowering the blood sugar level and increasing the efficiency of using insulin. It does not help treat type-1 diabetes.

Metformin belongs to the biguanides class of drugs.

It is proven to be effective in treating type-2 diabetes in adults and children older than 10 by decreasing the measure of glucose that a person absorbs from food and that made by the liver.
