Drugs for Angina Pectoris 2 Flashcards
beta blocker drugs
Propranolol (Inderal), metoprolol (Lopressor), carvedilol (Coreg)
beta blockers decrease cardiac oxygen demand by
blocking Beta 1 receptors from norepinephrine and epinephrine
result of beta blockers**
decrease heart rate, decrease blood pressure, decrease oxygen demand and oxygen consumption
adverse effects of beta blockers
Bradycardia; Decreased AV conduction; Reduction of contractility; Asthmatic effects; Caution with diabetes; Insomnia; Depression; Bizarre dreams; Sexual dysfunction
bradycardia adverse effect
speed up the heart too much
reduction of contractility adverse effect**
not going to pump as hard (left ventricle); negate autotropic effect
asthmatic adverse effects if not
a selective beta blocker
caution of beta blockers with
diabetes - hides symptoms of hypoglycemia
calcium channel blocker drugs
verapamil (Isoptin, Calan) diltiazem (Cardizem)
which calcium channel blocker do you see most often
diltiazem (Cardizem)
diltiazem (Cardizem)
see to decrease HR **; decrease number of times muscle contracts and to relax vessels; so vasodilating effect
calcium channel blockers do what
• Block calcium channels in vascular smooth muscle (Vascular Smooth Muscle)-primarily on the coronary vessels and in the AV node
calcium channel blockers increase
blood flow to the heart
calcium channel blockers decrease
impulses through the AV node
calcium channel blockers used to decrease
decrease workload of heart and slow the heart rate
calcium channel blockers used to treat
HTN, atrial fibrilliation, stable and variant angina
CA blockers used for
hypotension; atrium fiber latrim (decrease impuluses through AV node); stable and varient angina (will open up vessels)
“dipines”
peripheral vessel CA channel blockers - block CA from vessels = expand/vasodilate; also treats high bp or treatment of afib
dipines examples
Amlodipine (Norvasc); Felodipine (Plendil)**; Nifedipine (Procardia XL, Adalat); Nicardipine (Cardene); Isradipine (Dynacirc); Nisoldipine (Sular); Clevidipine (Cleviprex) for IV use vs. esmolol or IV nicardipine)
