3 types of drugs to treat angina
- organic nitrates
- beta blockers
- Ca++ channel blockers
drug types that decrease O2 demand
- organic nitrates
- beta blockers
drug type that increases O2 supply

Ca++ blocker
organic nitrates - basically, what do they do?

dilate vascular smooth muscle --> decreases the amount of work the heart must perform --> decreases myocardial O2 demand
2 organic nitrate drugs
- nitroglycerin
- isosorbide dinitrate
nitrates are drug precursors that become active when converted to __ within __
- nitrous oxide
- vascular smooth muscle
nitroglycerin
- a nitrate
- causes vasodilation
nitroglycerin - admin how? list in order from fastest to slowest impact

sublingual, buccal, oral, transdermal
isosorbide dinitrate
- a nitrate
- causes vasodilation
- lasts longer than nitroglycerin
to treat stable angina, use what types of drugs?
- beta blockers and organic nitrates
- Ca++ channel blockers too, but they only impact the myocardium and periph vasculature -- they don't dilate coronary arteries
what kinds of meds to use for variant angina?
- Ca++ channel blockers
- (nitrates can be used for severe forms)
unstable angina - use what drug types?

determined pt by pt
beta-adrenergic blockers - basically, do what?

decrease HR and force of contraction --> decreases the heart's workload --> decreases O2 demande
2 beta blockers
- atenolol
- netoprolol
calcium channel blockers - basically, do what?

relax and dilate the blood vessels
2 calcium channel blockers
- diltiazem
- nifedipine
atenolol and metoprolol are what type of drug?

beta-blockers (decrease O2 demand by decreasing heart workload)
diltiazem and nifedipine are what type of drug?

calcium channel blockers (relax/dilate blood vessels)
