Study Notes
Antihypertensives
- Antihypertensives primarily target the renin-angiotensin system, a potent vasoconstrictor, to lower blood pressure.
- This system's vasoconstriction action elevates blood pressure.
- Calcium channel blockers, beta blockers, and peripheral vasodilators diminish heart rate and/or blood pressure.
- Antihypertensives are used for hypertension, hypertensive emergencies, and to diagnose pheochromocytoma (a tumor of the adrenal glands that causes high blood pressure).
Adverse Effects
- Peripheral Vasodilators: Hypotension, dizziness, angina, headache, hirsutism, nasal congestion, fatigue, sodium and water retention.
- Beta Blockers: Bradycardia, hypotension, heart failure, dizziness, arrhythmias, decreased libido, impotence, constipation, diarrhea.
- Central Acting Anti-Adrenergics: Drowsiness, sedation, headache, dry mouth, hypotension, syncope, fluid retention, constipation.
- Peripheral Acting Anti-Adrenergics: Headache, fatigue, hypotension, lethargy, dyspepsia (heartburn), headache.
- Alpha Adrenergics: Headache, fatigue, hypotension, sexual dysfunction, lack of energy.
- ACE Inhibitors: Cough, nausea, hypotension, headache, fatigue.
- Angiotensin II Receptor Antagonists: Diarrhea, abdominal pain, hypotension, fatigue, headache, lightheadedness, upper respiratory symptoms, cough.
- Hypertensive Emergency Drugs: Dizziness, weakness, nausea, vomiting, sodium and water retention, apprehensive feeling, headaches.
Drug Classes and Examples
- Beta Blockers: End in "olol" (e.g., Metoprolol, Atenolol, Propranolol)
- Calcium Channel Blockers: Examples include Diltiazem, Verapamil, Amlodipine
- Central Acting Anti-Adrenergics: Examples include Clonidine, Methyldopa
- Peripheral Acting Anti-Adrenergics: Examples include Guanabenz, Guanfacine
- Alpha Adrenergics: Examples include Prazosin, Terazosin, Doxazosin
- ACE Inhibitors: End in "pril" (e.g., Captopril, Enalapril, Lisinopril)
- Angiotensin II Receptor Antagonists: End in "sartan" (e.g., Losartan, Valsartan, Candesartan)
- Hypertensive Emergency Drugs: IV only, used in emergency rooms and CCUs (e.g., Nitroprusside, Nicardipine, Fenoldopam)
Administration and Monitoring
- Always check blood pressure before administering antihypertensives.
- Monitor for adverse effects and notify the doctor if necessary.
- Be aware of orthostatic hypotension and have the patient dangle their feet before getting out of bed.
- Do not stop taking antihypertensives abruptly.
- Teach patients to recognize the signs of heart failure (sudden weight gain, fluid retention, edema, shortness of breath).
- Encourage patients to follow up with a physician for regular blood pressure checks.
Important Considerations
- Aldomet (methyldopa) can turn urine brown.
- Regitine (phentolamine) is an alpha adrenergic blocker.
- Coreg (carvedilol) is a popular alpha-beta blocker.
- Many antihypertensives can cause sexual dysfunction and lack of energy.
- Over-the-counter preparations can interact with antihypertensives and increase blood pressure; check with a healthcare provider.
Antihypertensives
- Most antihypertensives target the renin-angiotensin system, which is a potent vasoconstrictor
- Vasoconstriction increases blood pressure
- Calcium channel blockers, beta blockers, and peripheral vasodilators decrease heart rate and/or blood pressure
- Check pulse and blood pressure before and during administration of beta blockers and calcium channel blockers
- All antihypertensives can lead to hypotension
- Antihypertensives are used to treat hypertension and hypertensive emergencies and to diagnose pheochromocytoma
Adverse Effects
- Peripheral Vasodilators: Hypotension, dizziness, angina, headache, hirsutism, nasal congestion, fatigue, sodium and water retention
- Beta Blockers: Bradycardia, hypotension, heart failure, dizziness, arrhythmias, decreased libido, impotence, constipation, diarrhea
