==Mechanism of Action==
==Mechanism of Action==
Pioglitazone is a thiazolidinedione that works by enhancing insulin sensitivity. It activates peroxisome proliferator-activated receptor-gamma (PPARγ) in fat, muscle, and liver tissues, which helps control the production of hormones and enzymes that improve insulin sensitivity, lower blood sugar, reduce glucose production in the liver, and maintain the function of pancreatic β-cells.
Activates peroxisome proliferator-activated receptor gamma (PPAR-γ), increasing insulin sensitivity in peripheral tissues (in fat, muscle and liver tissues).

**Initial dose is 15 mg or 30 mg once daily. The dose can be increased up to 45 mg once daily based on glycemic response.
*Heart failure (NYHA Class I-II): Start at 15 mg once daily
*Hypertension
*No dose adjustment is needed for hypertension or mild-moderate renal impairment
**No specific dosage adjustment for hypertension alone, but careful monitoring is required due to potential fluid retention.
*Severe renal impairment (eGFR <30 mL/min): Use with caution, start at a lower dose
*Heart Failure (NYHA Class I or II)
 
**Initial dose is 15 mg once daily. Dose adjustments should be made cautiously with careful monitoring for signs of heart failure.
*Diabetic Kidney Disease
**No specific dosage adjustment, but careful monitoring is required due to potential fluid retention and renal function.
