Unit 1: Medications Flashcards

1
Q

Amiodarone MOA

A

Class III Antidysrhythmic
- Blocks K+-channels (prolongs diastole)
- Decreases HR, contractility, + conductivity
(negative inotrope, chronotrope, dromotrope)

Antiadrenergic
Blocks beta-1 receptors (vasodilation)

Q

Diltiazem MOA

A

CCB (effect on heart same as BBs)
- blocks Ca2+ influx in sm. muscle, preventing contraction
- Decreases HR, contractility, + conductivity
- Vasodilation → Increases cardiac perfusion
