  1. Nitrates
    Nitroglycerin (Nitro-Bid)
    • Decrease preload and causes venodilation. Higher doses can cause vasodilation.
    • Postural hypotension, tachycardia, contact dermatitis, can cause headaches.
    • Amyl nitrate is flammable. Dosages of nitrates are not interchangeable. Store in original container and keep closed tightly. For IV--must be in glass bottle and special tubing. ***Remove transdermal patches before cardioversion or defibrillation to prevent burns!!!! Wear gloves with ointment. Rotate sites. Remove old patch before applying new. Transdermal should be on for 12 hours during the day then off for 12 hours at night-decrease tolerence to med.**Do not trim patch** Risk with ergot derivitives and heparin. Not for use with ED meds.
    • Stable or unstable angina. Variant angina.
  2. BetaBlockers (olol)
    Metoprolol (Toprol)
    • Blocks Beta-adrenergic receptors to decrease pulse, BP and contractility.
    • Hypotension, heart block, bradycardia, CHF, Unusual dreams, impotence, altered glucose, wheezing, bronchospasm.
    • Monitor BP and P. Assess frequency of angina attacks. Use orally for angina. Can cause HTN if given with clonidine. Less effective if taken with NSAIDS. Can alter blood glucose.
    • Stable or unstable angina.
  3. Calcium Channel Blockers
    (CCB---CCC---Constipation)
    (CCB--Very Nice Drugs--verapamil, norvasc, diltiazem)
    Dilitiazem (Cardizem)
    • Decrease afterload and O2 demand by dilating arterioles and decreasing myocardial contractility. (some in this classification may decrease pulse).
    • HTN, Brady/Tachycardia, palpitations, peripheral edema, flush, constipation.
    • Monitor P and BP. Assess frequency of angina attacks. Use orally for angina. Extended release should not be chewed, opened, or broken. Encourage high fiber diet to prevent constipation. Risk of heart block and Dig toxicity with verapamil.
    • Stable or unstable angina.
    • Treatment of Prinzmetal's Angina.
    • Inhibits the movement of CA+ ions across the membranes of myocardial and arterial muscle cells altering the action potential and blocking muscle cell contraction.
