Actos (generic name pioglitazone) is a prescription drug used to treat Type 2 diabetes. It was originally approved by the FDA in July, 1999. Actos is part of a group of drugs called thiazolidinediones, which act primarily by decreasing insulin resistance and helping insulin work better in muscle and fat. This drug is used alone or in combination with insulin or another antidiabetic medication.
