What should I check before giving calcium channel blockers?
Check the BP and HR Two of the most important things that nurses have to consider before giving calcium channel blockers are the client’s blood pressure and heart rate. It is advisable to check these two factors at least 30 minutes before the drug is given.
What class of drugs are calcium channel blockers?
Calcium channel blocking agents are generally classified into three groups according to their chemical structure: benzothiazepines (diltiazem); phenylalkylamines (verapamil); and the dihydropyridines (amlodipine, bepridil, felodipine, isradipine, nicardipine, nifedipine, and nisoldipine).
What is the mechanism of calcium channel blockers?
Calcium channel blockers are medications used to lower blood pressure. They work by preventing calcium from entering the cells of the heart and arteries. Calcium causes the heart and arteries to squeeze (contract) more strongly. By blocking calcium, calcium channel blockers allow blood vessels to relax and open.
What is the most commonly prescribed calcium channel blocker?
The dihydropyridine calcium channel blockers, a group that includes amlodipine, felodipine and lacidipine, are a common choice for treatment of hypertension. Amlodipine, which is both low cost and taken once daily, is the one of the most commonly prescribed agents.
When should calcium channel blockers be avoided?
In general, patients who have certain types of heart problems or low blood pressure may not be able to take calcium channel blockers. Other reasons why you may not be able to take some of these medications include pregnancy, heart problems, liver problems, or certain types of irregular heart rhythms.
What should you assess before giving beta blockers?
Because beta blockers lower the heart rate and blood pressure, you will need to monitor your patient for bradycardia and hypotension, including orthostatic hypotension. With that said, always get a blood pressure and heart rate prior to giving the dose.
Which calcium channel blocker slows heart rate?
Calcium channel blockers relax and widen blood vessels. This makes it easier for blood to flow through the vessels and lowers blood pressure. Diltiazem and verapamil also slow the heart rate and affect the pumping action of the heart.
What is the best alternative to amlodipine?
Top 5 amlodipine alternatives
- Other calcium channel blockers (such as nifedipine, diltiazem, or verapamil)
- ACE Inhibitors (such as lisinopril, ramipril, or benazepril)
- ARBs (such as losartan, telmisartan, or candesartan)
- Beta-blockers (such as carvedilol, metoprolol, or bisoprolol)
Which CCB is best for hypertension?
Dihydropyridine CCB amlodipine is the most frequently prescribed and efficacious in the monotherapy for hypertension compared with other classes of CCBs.
Who should not use calcium channel blockers?
You have kidney or liver disease. You have low blood sugar. This medicine can lower your blood sugar if your daily dose is more than 60 mg. You have Parkinson’s disease.
Why do you avoid CCB in heart failure?
Calcium channel blockers should generally be avoided in patients with heart failure with reduced ejection fraction (HFrEF) since they provide no functional or mortality benefit and some first generation agents may worsen outcomes [1].
What should be checked before giving propranolol?
Assess heart rate, ECG, and heart sounds, especially during exercise (See Appendices G, H). Report immediately an unusually slow heart rate (bradycardia) or signs of other arrhythmias, including palpitations, chest discomfort, shortness of breath, fainting, and fatigue/weakness.

Which calcium channel blocker has the least side effects?

- amlodipine (Norvasc)
- felodipine (Plendil)
- isradipine (DynaCirc)
- nicardipine (Cardene)
- nifedipine (Adalat, Procardia)

Why amLODIPine is taken at night?
Overnight blood pressure control is important in order to lower your risk. If your medication wears off before your next dose is due, your blood pressure may be elevated for several hours while you sleep. You may also wake with high blood pressure. Taking your medication at bedtime may help prevent this issue.
Do calcium channel blockers lower BP?
Calcium channel blockers are a group of medications that limit how your body uses calcium. By slowing down how your cells use calcium, these medications can lower your blood pressure, prevent heart rhythm problems and more.
