Thiazolidinediones (Glitazones):Uses,Dosages,Side-effects & Brand
Thiazolidinediones, also distinguished as glitazones, are a group of oral anti-diabetic medications that may be practiced for the treatment of type 2 diabetes. They are classed as oral hypoglycemic drugs along with metformin, they are taken once or twice daily with or without food. Glitazones also further lower blood pressure and enhance lipid metabolism by increasing levels of HDL (or ‘good cholesterol) cholesterol.
A thiazolidinedione may be suggested as a treatment for people with type 2 diabetes if metformin and either sulphonylureas or prandial glucose regulators are not successful in lowering blood glucose levels adequately.
How Do Glitazones Work?
TZDs work by targeting the PPAR-gamma receptor, which produces new fat cells, and those cells are actually more sensitive to insulin, they allow insulin to do its job.
TZDs can, therefore, help boost insulin sensitivity and preserve the function of insulin-producing cells, but they do raise the risk of weight gain.
