Study Notes
Antihypertensives
- Antihypertensives are drugs used to lower blood pressure.
- Physiologic risk factors for hypertension include excessive fluid intake, vasoconstriction, excessive intake of saturated fat and simple carbohydrates, alcohol intake (increases renin secretions), and obesity.
- Cultural responses to antihypertensive agents differ between groups, including African Americans and Asian Americans.
Nonpharmacological Control of Hypertension
- Nonpharmacologic methods to control hypertension include stress-reduction techniques, exercise, salt restriction, decrease alcohol ingestion, and smoking cessation.
Antihypertensive Drugs
- Diuretics, beta-adrenergic blockers, alpha-adrenergic blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, and angiotensin II receptor blockers are types of antihypertensive drugs.
Beta-Adrenergic Blockers
- Beta-adrenergic blockers end in "-olol."
- Metoprolol is a more selective beta₁ blocker.
- Propranolol is a nonselective beta₁ and beta₂ blocker.
- Action: Blocks adrenergic affect, lowering blood pressure and heart rate.
- Uses include hypertension, anti-dysrhythmic, and anti-angina.
- It can be used as dual therapy with diuretics for African Americans.
- Side effects/adverse reactions are similar to those studied in unit 4.
- Contraindications are the same as those studied in unit 4. Propranolol is contraindicated in those with asthma or COPD.
- Interactions are the same as those in unit 4.
Alpha-Adrenergic Blockers
- Alpha-adrenergic blockers include prazosin.
- Action: Blocks alpha-adrenergic receptors, leading to vasodilation and decreased blood pressure.
- Uses include hypertension, heart failure, benign prostatic hypertrophy.
- It can be used as monotherapy for African Americans.
- Side effects/adverse reactions can include dizziness, drowsiness, headache, peripheral edema, weight gain, urinary incontinence, erectile dysfunction, orthostatic hypotension, palpitations, and elevated liver enzymes.
- Contraindications include caution and decreased blood pressure.
- Interactions include other drugs that lower blood pressure, high protein-binding drugs, alcohol, and over-the-counter (OTC) cold medications.
Calcium Channel Blockers
- Calcium channel blockers end in "-pine."
- Amlodipine, verapamil, and diltiazem are examples.
- Action: Blocks calcium movement in and out of cells, promoting vasodilation and decreasing heart rate.
- Uses include hypertension, anti-angina, anti-dysrhythmic, and peripheral vascular disease.
- It can be used as monotherapy for African Americans.
- Side effects/adverse reactions can include flushing, headache, dizziness, peripheral edema, erectile dysfunction, hypotension, and bradycardia.
- Contraindications include caution and hepatic impairment.
- Interactions include other drugs that lower blood pressure and cold medications.
Angiotensin-Converting Enzyme (ACE) Inhibitors
- ACE inhibitors end in "-pril."
- Lisinopril is an example.
- Action: Inhibits angiotensin II formation, blocking vasoconstriction and aldosterone release; increases water and sodium excretion, and potassium retention.
- Uses include hypertension and heart failure.
- It can be used as dual therapy along with diuretics for African Americans.
- Side effects/adverse reactions include a constant irritating cough, headache, GI upset, insomnia, erectile dysfunction, orthostatic hypotension, hyperkalemia, tachycardia, and angioedema.
- Contraindications include pregnancy and use with potassium-sparing diuretics or salt substitutes containing potassium.
- Interactions include potassium-containing medications, other antihypertensives, and OTC cold medications.
Angiotensin II Receptor Blockers (ARBs)
- ARBs end in "-sartan" or "-tan."
- Losartan is an example.
- Action: Blocks angiotensin II binding to receptors, inhibiting vasoconstriction and aldosterone release, thereby promoting sodium and water release and potassium retention.
- Uses include hypertension and heart failure.
- Side effects/adverse reactions include dizziness, drowsiness, fatigue, insomnia, headache, erectile dysfunction, orthostatic hypotension, hyperkalemia, hypotension, and renal dysfunction.
- Contraindications include pregnancy and lactation.
- Interactions include other antihypertensives, alcohol,NSAIDs, and OTC cold medications.
Nursing Process for Antihypertensives
- Assessment: Vital signs, knowledge of drugs that lower heart rate and electrolytes, medication and medical history, renal and liver function, weight, edema, and I&O are considerations.
- Teaching: Take blood pressure and pulse daily. Report changes. Weigh daily and report consistent gains. Get up slowly. Do not abruptly stop taking antihypertensives. Check with healthcare providers before taking OTC meds, especially cold medications. Teach diabetes patient interactions. ACE inhibitors and ARBs - teach no salt substitutes with K, low K diet, no potassium supplements
