How CYCLOSET Works

Cycloset is a sympatholytic dopamine D2 receptor agonist. While the precise mechanism for glycemic control is not fully elucidated, timed morning administration is associated with increased insulin sensitivity and improved glucose disposal. This results in reduced fasting and postprandial hyperglycemia without stimulating additional insulin secretion.
