Q

Wat is the mechanism of action of adenosine?

A

it interrupts AV node and resets it to sinus rhythm - causes brief asystole and bradycardia then returns to normal (as it is metabolised quickly)

Q

What is the mechanism of action for adrenaline in anaphylaxis?

A

It causes vasoconstriction by stimulating alpha-adrenergic receptors, counteracting the widespread vasodilation and vascular permeability seen in anaphylaxis. This reduces the loss of intravascular fluid and the subsequent hypotension.

Q

What is the mechanism of action of aldosterone antagonists?

A

They block the action of aldosterone, which increases sodium excretion and potassium retention by the principal cells of the kidney. Water follows sodium to be excreted, resulting in a diuretic effect.
