Drug Name: Pioglitazone
Synonyms: (±)-5-((4-(2-(5-ethyl-2-pyridinyl)ethoxy)phenyl)methyl)-2,4-thiazolidinedione; 5-{4-[2-(5-ethylpyridin-2-yl)ethoxy]benzyl}-1,3-thiazolidine-2,4-dione; Pioglitazone

DrugBank ID: DB01132
DrugBank Description: Pioglitazone is an antihyperglycemic used as an adjunct to diet, exercise, and other antidiabetic medications to manage type 2 diabetes mellitus. It is administered as a racemic mixture, though there is no pharmacologic difference between the enantiomers and they appear to interconvert _in vivo_ with little consequence. The thiazolidinedione class of medications, which also includes and , exerts its pharmacological effect primarily by promoting insulin sensitivity and the improved uptake of blood glucose via agonism at the peroxisome proliferator-activated receptor-gamma (PPARγ). PPARs are ligand-activated transcription factors that are involved in the expression of more than 100 genes and affect numerous metabolic processes, most notably lipid and glucose homeostasis. Thiazolidinediones, including pioglitazone, have fallen out of favor in recent years due to the presence of multiple adverse effects and warnings regarding their use (e.g. congestive heart failure, bladder cancer) and the availability of safer and more effective alternatives for patients with type 2 diabetes mellitus.

DrugBank MoA: Pioglitazone is a selective agonist at peroxisome proliferator-activated receptor-gamma (PPARγ) in target tissues for insulin action such as adipose tissue, skeletal muscle, and liver. Activation of PPARγ increases the transcription of insulin-responsive genes involved in the control of glucose and lipid production, transport, and utilization. Through this mechanism, pioglitazone both enhances tissue sensitivity to insulin and reduces the hepatic production of glucose (i.e. gluconeogenesis) - insulin resistance associated with type 2 diabetes mellitus is therefore improved without an increase in insulin secretion by pancreatic beta cells.
DrugBank Pharmacology: Pioglitazone enhances cellular responsiveness to insulin, increases insulin-dependent glucose disposal, and improves impaired glucose homeostasis. In patients with type 2 diabetes mellitus, these effects result in lower plasma glucose concentrations, lower plasma insulin concentrations, and lower HbA1c values. Significant fluid retention leading to the development/exacerbation of congestive heart failure has been reported with pioglitazone - avoid its use in patients in heart failure or at risk of developing heart failure. There is some evidence that pioglitazone may be associated with an increased risk of developing bladder cancer. Pioglitazone should not be used in patients with active bladder cancer and should be used with caution in patients with a history of bladder cancer.
DrugBank Indication: Pioglitazone is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. It is also available in combination with , , or for the same indication.
