quick cardio drug spitfire

Question 1

digoxin

Answer 1

inhibits Na/K pump resulting in more calcium available which improves contractility, lots of adverse effects

Question 2

pimobendan

Answer 2

an ionodilator
sensitizes troponin C to calcium, imporving the strength of contraction, reduces preload and afterload

Question 3

dobutamine/dopamine

Answer 3

dobutamine: beta 1 agonist, short half life, given CRI, used in hospital

Question 4

epinephrine

Answer 4

non selective adrenergic agonist, increases HR and positive inotrope, is also a bronchodilator due to beta 2 effects, used for emergencies only

Question 5

propanolol

Answer 5

non selective beta blocker, neg chronotrope, and a vaso/bronchodilator

Question 6

atenolol

Answer 6

selective beta 1 blocker, use over proanolol is concern for lungs

Question 7

atropine

Answer 7

anticholinergic, increases cAMP, increases HR and cardiac output

Question 8

lidocaine

Answer 8

fast sodium channel blocker, decreasing conduction velocity, treat ventricular tachyarrhtymias

Question 9

quinidine

Answer 9

a fast sodium channel blocker, decreasing conduction velocity, treats atrial arrthymias and increases effective refractory period

Question 10

procainamide

Answer 10

fast sodium channel blocker, decreasing conduction velocity, for ventricular arrhytmias

Question 11

sotalol

Answer 11

potassium channel blocker, slows repolarization, also a beta blocker, for ventricular arrthymias

Question 12

Amlodipine

Answer 12

calciu,m channel blocker, mostly works on vasculature, causes vasodilation and decreases afterload, first choice for CKD in cats

Question 13

diltiazem

Answer 13

calcium channel blocker in nodal tissue, vasodilator, neg dromotrope/notrope/chronotrope

Question 14

enalapril

Answer 14

ACE inhibitor: vasodilation and decrease afterload, diuretic

Question 15

benazapril

Answer 15

ACE inhibitor: vasodilation and decrease afterload, diuretic
