Pioglitazone + Metformin Hydrochloride: Brands, Price & Uses in Bangladesh

Pioglitazone + Metformin Hydrochloride is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus, specifically in patients who are not adequately controlled on metformin or pioglitazone monotherapy alone, or in patients already being treated with a combination of pioglitazone and metformin as separate tablets.

• Established use: Type 2 diabetes mellitus, as an adjunct to diet and exercise, when monotherapy with either component fails to provide adequate glycemic control.
• Not indicated for: Type 1 diabetes mellitus or diabetic ketoacidosis.

Pioglitazone + Metformin Hydrochloride is not a first-line agent for treatment-naive patients and should be initiated only after an inadequate response to single-agent therapy, or as a continuation for patients already stable on both components individually.

Pioglitazone + Metformin Hydrochloride should be individualized based on the patient's current antidiabetic therapy, effectiveness, and tolerability, and should always be taken exactly as prescribed by a physician.

Adult Dosing

Doses are generally titrated gradually based on glycemic response and tolerability. Maximum recommended dose is typically 45 mg pioglitazone and 2550 mg metformin per day, given in divided doses. Pioglitazone + Metformin Hydrochloride should be taken with meals to reduce gastrointestinal side effects.
