What are the indications of insulin?
DM

Hyperkalemia
What are the sites of degeneration of insulin?
Liver
Kidney
Muscle
How is insulin degraded in the liver?
50% is destroyed in a single passage before reaching the general circulation. In severe impairment, insulin metabolism decreases and thus there is longer half life
How is insulin degraded in the kidney?
Filtrated by glomeruli, reabsorption by tubules, degradation in tubule. In severe impairment, insulin metabolism decreases and thus there is longer half life
How is insulin degraded in the muscle?
Minor significance
What are the adverse effects of insulin?
Lipoatrphy or lipohypertrophy Edema Allergic skin reactions Anaphylaxis (rare) Hypokalemia Hypoglycemia Acute bronchospasm
Why does insulin cause hypokalaemia?
because insulin enhances K+ influx into cells.
