Glipizide is an oral hypoglycemic agent that belongs to the second generation sulfonylurea drug class that is used for the control of blood sugar levels in patients with type 2 diabetes. First introduced in 1984, Glipizide is available in various countries including Canada and the US. Sulfonylurea drugs are considered second-line glucose-lowering therapy following metformin. Sulfonylureas require functional pancreatic beta cells for their therapeutic effectiveness, which makes them more commonly used for early-stage type 2 diabetes when there is no progressed pancreatic failure, which enhances their hypoglycemic potency.
Glipizide displays rapid absorption and onset of action with the shortest half-life and duration of action, reducing the risk from long-lasting hypoglycemia that is often noticed with blood glucose-lowering agents.
Together with proper diet and exercise, Glipizide is used to control high blood sugar in people with type 2 diabetes.
Glipizide must be taken by mouth 30 minutes before breakfast or the first meal of the day as directed by your doctor. Glipizide is usually taken once daily or twice daily. Patients taking high doses of Glipizide may be directed by their doctor to take it twice daily. The dosage of Glipizide is based on the medical conditions and your response to treatment.
Your doctor may choose to reduce your risk of side effects from Glipizide by directing you to start using this medication at the lowest dose then gradually increasing it. you should follow your doctor’s instructions carefully.
