    Study Notes

    Calcium Channel Blockers (CCB)

    • Prevent calcium from entering cells, especially in the heart and blood vessels, decreasing heart rate and myocardial contraction.
    • Used for hypertension, angina pectoris, and dysrhythmias, maybe migraines.
    • Category C.

    Cardiac Glycosides

    • Inotropic, increasing force of contraction, slowing conduction, and increasing refractory period.
    • Used for hypertension, heart failure (HF), and dysrhythmias.
    • Reduces symptoms and increases exercise tolerance.
    • Adverse effects: headaches, drowsiness, flushing, fatigue, dizziness, and edema.

    Vasodilators

    • Hydralazine: used for high blood pressure, heart failure, and hypertensive emergency.
    • Minoxidil: used for severe hypertension, but with potential serious side effects.
    • Nitroprusside: used for hypertensive emergency, acts fast.

    Renin-Angiotensin-Aldosterone System (RAAS)

    • Angiotensin Converting Enzyme (ACE) Inhibitors
      • Mechanism: reduces levels of angiotensin II, dilates blood vessels, increases levels of bradykinins.
      • Uses: hypertension, heart failure, myocardial infarction (MI), and nephropathy.
      • Adverse effects: cough, angioedema, and hyperkalemia.
    • Angiotensin Receptor Blockers (ARBs)
      • Mechanism: blocks access to receptors in blood vessels, reducing levels of angiotensin II.
      • Uses: hypertension, heart failure, myocardial infarction (MI), and nephropathy.
      • Adverse effects: cough, angioedema, and hyperkalemia (less common).

    Direct Renin Inhibitors

    • Aliskiren: inhibits the conversion of angiotensinogen into angiotensin I, suppressing the entire RAAS.
    • Used for hypertension.

    Aldosterone Antagonists

    • Eplerenone: selective aldosterone receptor blocker, used for hypertension and heart failure.

    Anti-Dysrhythmics

    • Several categories: sodium channel blockers, beta blockers, potassium channel blockers, calcium channel blockers, and others.
    • Uses: dysrhythmias, changing EKG.
    • Adverse effects: anorexia, nausea, vomiting, diplopia, and dysrhythmias.

    Organic Nitrates

    • Used for angina pectoris, reducing oxygen demand by dilating veins.
    • Adverse effects: headache, orthostatic hypotension, and reflex tachycardia.
    • Nitroglycerin: used for angina pectoris, available in various routes and durations.
