    Study Notes

    Insulin Therapies

    • There are three types of insulin therapies: “split-mixed” insulin, basal-bolus regimens using multiple daily injections (MDI), and continuous subcutaneous insulin infusion (CSII) pump therapy.

    Amylinomimetics

    • Pramlintide is an analogue of amylin, a small peptide hormone released by the β cells of the pancreas along with insulin after a meal.
    • Amylin is completely absent in individuals with Type I diabetes.

    Pramlintide: Benefits and Risks

    • Benefits: moderate A1c reduction.
    • Risks/side effects: hypoglycemia, contraindications similar to GLP-1 agonists.
    • Concomitant use of diuretics may cause orthostatic hypotension and electrolyte abnormalities; loop diuretics may need to be discontinued.

    GLP-1 Agonists

    • Agents: lixisenatide, exenatide, liraglutide, albiglutide, and dulaglutide.
    • GLP-1 agonists are noninsulin injectable agents.
    • Tirzepatide is the only agent currently approved for treatment of T2D.

    Kidney Function and GFR

    • Patients with a GFR of 45-60 ml/min/1.73m2 may be less effective at responding to certain treatments.

    GLP-1 Agonists

    • GLP-1 (Glucagon-Like Peptide 1) Agonists are noninsulin injectable agents used to treat T2D.
    • Examples of GLP-1 Agonists include lixisenatide, Exenatide, Liraglutide, Albiglutide, and Dulaglutide.
    • Tirzepatide is the only agent currently approved for T2D treatment and is weight neutral.

    SGLT-2 Inhibitors

    • SGLT-2 (Sodium-Glucose Co-transporter 2) Inhibitors work by inhibiting SGLT2 in the proximal nephron, reducing glucose reabsorption and increasing urinary glucose excretion by up to 80 g/day.
    • Dextrose IV may be required for unconscious patients, and Glucagon, 1 g intramuscularly, is preferred in unconscious patients when IV access cannot be established.

    Insulin Sensitizers - DPP-4 Inhibitors

    • DPP-4 (Dipeptidyl Peptidase IV) Inhibitors work by inhibiting the breakdown of GLP-1 secreted during meals, which increases pancreatic insulin secretion.
    • Examples of DPP-4 Inhibitors include Sitagliptin (Januvia), Saxagliptin, Linagliptin, Alogliptin, and Vildagliptin.

    Kidney Function and GFR

    • Patients with a GFR of 45-60 ml/min/1.73m2 may be less effective at responding to certain treatments.

    GLP-1 Agonists

    • GLP-1 (Glucagon-Like Peptide 1) Agonists are noninsulin injectable agents used to treat T2D.
    • Examples of GLP-1 Agonists include lixisenatide, Exenatide, Liraglutide, Albiglutide, and Dulaglutide.
    • Tirzepatide is the only agent currently approved for T2D treatment and is weight neutral.
