WARNING: CONGESTIVE HEART FAILURE
Thiazolidinediones, including ACTOS, cause or exacerbate congestive heart failure in some patients [see Warnings and Precautions].
After initiation of ACTOS, and after dose increases, monitor patients carefully for signs and symptoms of heart failure (e.g., excessive, rapid weight gain, dyspnea, and/or edema). If heart failure develops, it should be managed according to current standards of care and discontinuation or dose reduction of ACTOS must be considered.
ACTOS is not recommended in patients with symptomatic heart failure.
Initiation of ACTOS in patients with established New York Heart Association (NYHA) Class III or IV heart failure is contraindicated [see Contraindications and Warnings and Precautions].
ACTOS tablets are a thiazolidinedione and an agonist for peroxisome proliferator-activated receptor (PPAR) gamma that contains an oral antidiabetic medication: pioglitazone.
Pioglitazone [(±)-5-[[4-[2-(5-ethyl-2-pyridinyl) ethoxy] phenyl] methyl]-2,4-] thiazolidinedione monohydrochloride contains one asymmetric carbon, and the compound is synthesized and used as the racemic mixture. The two enantiomers of pioglitazone interconvert in vivo. No differences were found in the pharmacologic activity between the two enantiomers.
Monotherapy and Combination Therapy
ACTOS is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus in multiple clinical settings [see Clinical Studies].
Important Limitations of Use
ACTOS exerts its antihyperglycemic effect only in the presence of endogenous insulin. ACTOS should not be used to treat type 1 diabetes or diabetic ketoacidosis, as it would not be effective in these settings.
Use caution in patients with liver disease [see Warnings and Precautions].

Pioglitazone for Hepatic Steatosis in HIV/HCV Co-infection. 
Background Chronic hepatitis C infection frequently coexists with human
immunodeficiency virus (HIV) and together are associated with increased hepatic
steatosis... This small study shows that pioglitazone
helps ameliorate steatosis in the context of HIV/HCV co-infection.

Rosiglitazone and pioglitazone for the treatment of Alzheimer's disease. [2011.11]
CONCLUSIONS: Results from clinical trials and current safety data suggest that rosiglitazone should not be used for the treatment of AD. Application of results from trials evaluating pioglitazone in the treatment of AD is limited because of major trial limitations; therefore, it should not be recommended at this time. Although these drugs are not commonly used in the treatment of AD, further pharmacoepidemiologic studies are warranted before their use can be recommended.
Clinical Trials Related to Actos (Pioglitazone)
Effects of Pioglitazone on Platelet Function [Active, not recruiting]
The purpose of this study is to determine how pioglitazone and aspirin affect platelets in
the blood of diabetic and non-diabetic subjects. Platelets are small cells in the blood
that help with blood clotting. Pioglitazone is a drug that is used to lower blood sugar and
fats by helping the body to use insulin correctly. Pioglitazone is presently used to treat
diabetes but has not been approved for non-diabetics. This study will determine whether
pioglitazone reduces the activity of platelets in people who are or are not also taking
Effect of Pioglitazone and Exenatide on Body Weight and Beta Cell Function [Completed]
Pioglitazone, a drug used in treatment of type 2 diabetes has been shown to improve insulin
sensitivity in skeletal muscle, liver, and fat cells. Despite the beneficial effects of
pioglitazone to improve insulin sensitivity and reduce cardiovascular disease in high risk
type 2 diabetic patients, weight gain has been a limiting factor. Exenatide, another
agent used for treatment of T2DM, improves glycemic control and promotes moderate weight
loss. In this proposal we will examine the effect of combination therapy with pioglitazone
plus exenatide on body weight, fat topography, beta cell function, glycemic control, and
plasma lipid levels in subjects with type 2 diabetes mellitus compared to treatment with
each drug separately. Assessment of beta cell function will be performed by measuring the
maximal insulin secretory capacity using a maximal hyperglycemic stimulus combined with an
intravenous arginine stimulus.
