    Study Notes

    Insulin Preparations Overview

    • Insulin binds to its receptor, activating tyrosine kinase, leading to:
      • Increased glucose storage as glycogen in the liver
      • Enhanced glycogen and protein synthesis in muscles
      • Increased triglyceride storage in fat tissues
      • Indirectly promotes potassium uptake alongside glucose

    Clinical Uses

    • Primarily used for managing diabetes.

    Side Effects

    • Common adverse effects include:
      • Hypoglycemia
      • Lipodystrophy (abnormal distribution of body fat)
      • Hypersensitivity reactions
      • Weight gain

    Contraindications

    • Specific contraindications are not listed; caution advised in patients with certain conditions.

    Examples of Insulin Preparations

    • Rapid-Acting: Lispro, Aspart, Glulisine

    • Long-Acting: Detemir, Glargine
    • Very Long Acting: Degludec

    Metformin

    • Mechanism:
      • Inhibits gluconeogenesis and mitochondrial glycerol-3-phosphate dehydrogenase (mGPD), essential in glucose production.
