    Study Notes

    Hypertension and Its Risks

    • Hypertension raises the likelihood of myocardial infarction (MI), heart failure, cerebral infarction and hemorrhage, and renal disease.

    Angiotensin-Converting Enzyme Inhibitors (ACE-I)

    • Captopril (Capoten): Reduces proteinuria; may cause prolonged elevation of creatinine.
    • Lisinopril (Prinivil): Slows renal impairment progression; should be taken 1 hour before or 2 hours after meals.
    • Benazepril (Lotensin): Beneficial for diabetes patients; can cause proteinuria.
    • Enalapril (Vasotec): Effective but may induce proteinuria and acute hypotension.
    • Fosinopril (Monopril): Requires monitoring for renal function and potassium levels.
    • Overall action: Decreases vasoconstriction and aldosterone production, promoting vasodilation and reducing sodium and water retention.

    Angiotensin II Receptor Blockers (ARBs)

    • Losartan (Cozaar): Similar effects to ACE-I but lower risk of hyperkalemia and cough.
    • Candesartan (Atacand) and Irbesartan (Avapro): Monitor for blood pressure and renal function.
    • Action: Increases renal flow and enhances excretion of electrolytes.

    Calcium Channel Blockers (CCBs)

    • Amlodipine (Norvasc): Widely used, dilates peripheral arteries, first-line for African American patients.
    • Diltiazem (Cardizem): Controls both heart rate and pressure, useful for angina.
    • Nifedipine (Procardia) and Verapamil (Calan): Alternative options based on specific patient needs.
    • Action: Relax vascular smooth muscle, reducing peripheral vascular resistance.

    Beta Blockers

    • Propranolol (Inderal): Acts on beta adrenergic receptors; useful in managing hypertension associated with tachycardia.
    • Caution: Can mask hypoglycemia symptoms; caution in patients with asthma or bradycardia.

    Aspirin's Role

    • Suppresses platelet aggregation, mitigating thrombus formation without harming endothelial function.

    Dyslipidemia Drugs - HMG-CoA Reductase Inhibitors

    • Atorvastatin (Lipitor) and others: Decrease cholesterol production; significant for heart disease prevention.
    • Indicated for women with cardiovascular disease; caution against grapefruit juice interaction.
    • Monitor for myopathies and liver function; be wary of muscle pain as it may indicate rhabdomyolysis.

    Cardiac Glycosides

    • Digoxin (Lanoxin): Enhances cardiac contractility (positive inotropic effect), beneficial in heart failure management.
