Hyperkalaemia Drugs Flashcards
What are the first line drugs for hyperkalaemia?
Calcium gluconate
Insulin/dextrose
Calcium resonium
What are the second line drugs for hyperkalaemia?
Sodium bicarbonate
Salbutamol
What is the action of calcium gluconate
Decreases excitability of cardiac myocytes
Protects the heart from hyperkalaemia
What is the action of insulin when treating hyperkalaemia?
Used with dextrose
Encourages glucose movement into cells
Promotes action of Na-K ATPase
Results in an intracellular potassium shift
What is the action of calcium resonium?
Removes potassium from body
Calcium ions swapped for potassium ions mainly in the large intestine
What is the action of sodium bicarbonate when treating hyperkalaemia?
Decreases acidosis
Causes protons out and potassium into cells
Action of salbutamol in hyperkalaemia?
Enhances insulin and dextrose action
Intracellular potassium shift
