    Study Notes

    Antihypertensive Therapy

    • For adults with stage 1 hypertension, first-line therapy with a blood pressure goal of less than 130/80 mm Hg involves the use of antihypertensive agents.

    Angiotensin-Converting Enzyme Inhibitors (ACEIs)

    • A common adverse drug reaction associated with ACEIs is angioedema.
    • Patients with a history of angioedema are more prone to experiencing angioedema as a side effect of ACEIs.
    • The main contraindication for using ACEIs is bilateral renal artery stenosis.
    • Patients on ACEIs require close potassium monitoring, especially those with kidney disease or heart failure.
    • Food intake can reduce the bioavailability of ACEIs, making dosing adjustments necessary.
    • A precaution associated with ACEIs is hyperkalemia.
    • ACEIs can cause fetal toxicity, making them contraindicated in pregnancy.

    Angiotensin Receptor Blockers (ARBs)

    • ARBs have a similar mechanism of action to ACEIs but do not inhibit the breakdown of bradykinin, which reduces the incidence of angioedema.
    • ARBs are considered a suitable alternative for patients who develop issues with ACEIs, such as angioedema or cough.
    • The mechanism of action of ARBs involves blocking the activation of angiotensin II receptors.

    Calcium Channel Blockers (CCBs)

    • The mechanism of action of CCBs like amlodipine and nifedipine involves relaxation of vascular smooth muscle, reducing peripheral resistance and blood pressure.

    Diuretics

    • The 2017 ACC/AHA guideline recommends chlorthalidone over HCTZ due to its longer duration of action.
    • A common adverse effect associated with thiazide and thiazide-like diuretics is hypokalemia.
    • Loop diuretics are indicated for hypertension management in patients with heart failure and chronic kidney disease.
    • Loop diuretics are commonly associated with hypokalemia.
    • Ethacrynic acid is a diuretic that can be safely used in patients allergic to sulfa moieties.
    • Thiazides should be used with caution in patients with impaired renal function due to the risk of acute kidney injury.
