Injectable medications are the cornerstone of therapy for Type 1 diabetes and a critical component of management for many patients with Type 2 diabetes. This therapeutic category has expanded beyond traditional insulins to include sophisticated agents like GLP-1 receptor agonists, a topic covered in detail in the “Pharmacology of Injectable Diabetes Medications” lecture within the Patient Care 5 curriculum.
