Insulin preparations are pharmacologically classified by their time-action profile — onset, peak, and duration — into rapid-acting, short-acting, intermediate-acting, long-acting, and ultra-long-acting categories, a distinction central to matching therapy to physiologic insulin needs. This connects to the concept of glycemic excursion, defined as the difference between blood glucose at the start and end of a meal, which determines prandial insulin dosing strategy. These classifications fall within diabetes pharmacology, and insulin's broader physiologic actions include suppression of protein catabolism in myocytes, hepatocytes, and adipocytes and promotion of triglyceride storage in adipocytes.
