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
- Short-Acting: Regular insulin
- Intermediate-Acting: NPH insulin
- Long-Acting: Detemir, Glargine
- Very Long Acting: Degludec
Metformin
- Mechanism:
- Inhibits gluconeogenesis and mitochondrial glycerol-3-phosphate dehydrogenase (mGPD), essential in glucose production.
- Inhibits glucagon’s blood sugar-raising effects.
- Enhances glycolysis and sensitivity of insulin receptors.
Clinical Uses for Metformin
- Utilized in diabetes management.
Side Effects of Metformin
- Notable side effects include gastrointestinal discomfort and lactic acidosis risk.
PPAR-y Activators (Thiazolidinediones)
- Mechanism:
- Activate PPAR-y, increasing insulin receptor sensitivity and enhancing glucose uptake.

Clinical Uses for PPAR-y Activators
- Also used in diabetes management.
Side Effects of PPAR-y Activators
- Associated side effects include:
- Weight gain
- Edema
- Heart failure risk
