From the Guidelines
Pioglitazone is primarily indicated for the treatment of type 2 diabetes mellitus as an adjunct to diet and exercise to improve glycemic control, with potential off-label uses including treatment of non-alcoholic steatohepatitis (NASH) and polycystic ovary syndrome (PCOS). The typical dosage ranges from 15 to 45 mg once daily, with most patients starting at 15 or 30 mg and titrating based on response 1. For approved indications, pioglitazone can be used as monotherapy or in combination with metformin, sulfonylureas, insulin, or DPP-4 inhibitors. Some key points to consider when prescribing pioglitazone include:
- Monitoring for potential side effects including fluid retention, weight gain, bone fractures (particularly in women), and heart failure exacerbation 1
- Contraindication in patients with established New York Heart Association Class III or IV heart failure 1
- Use with caution in patients with edema, heart failure risk factors, or bladder cancer risk 1
- Potential benefits in reducing liver inflammation and fibrosis in patients with NASH, particularly in non-diabetic patients with biopsy-proven NASH 1
- Investigation for use in PCOS to improve insulin sensitivity and ovulation rates in affected women
- Off-label use for HIV-associated lipodystrophy to address metabolic abnormalities. It's essential to weigh the benefits and risks of pioglitazone therapy, considering the individual patient's profile and medical history, to ensure optimal treatment outcomes and minimize potential adverse effects 1.

From the Research
Indications for Pioglitazone
The indications for Pioglitazone, a thiazolidinedione, are as follows:
- Approved for use in the treatment of type 2 diabetes mellitus, both as monotherapy and in combination with other antidiabetic agents such as metformin, sulfonylurea, or insulin 2, 3, 4, 5
- Effective in reducing blood glucose levels, improving glycemic control, and serum lipid profiles in patients with type 2 diabetes 2, 3, 4, 5
- Also effective in reducing some measures of cardiovascular risk and arteriosclerosis 3, 4, 6
Off-Label Uses
There is no evidence to suggest off-label uses for Pioglitazone beyond its approved indications for type 2 diabetes mellitus. However, its effects on cardiovascular risk factors may be beneficial in certain patient populations 6
Dosage and Administration
Pioglitazone can be administered once daily, with or without food, at doses of 15-30 mg/day 5
- Monotherapy or in combination with other antidiabetic agents, such as metformin, sulfonylurea, or insulin 2, 3, 4
- Dose titration may be necessary to achieve optimal glycemic control while minimizing adverse effects 2, 5
Safety and Efficacy
Pioglitazone is generally well-tolerated, with common adverse events including weight gain, edema, and mild decreases in hemoglobin concentrations 2, 3, 4, 5
