Insulin

Insulin treatment is required for all patients with Type 1 diabetes. Patients with Type 2 diabetes usually begin therapy with metformin and other combination meds, however insulin therapy is usually required as disease progresses.

Insulin products are categorized as rapid-acting, short-acting, intermediate-acting, and long-acting, based on their time course of absorption, elimination, metabolism and excretion. The followup post will give some examples of each class.
