What is dihydropyridine vs Nondihydropyridine?
Dihydropyridine CCBs have predominantly peripheral vasodilatory actions, whereas nondihydropyridine CCBs have significant sinoatrial (SA) and AV node depressant effects and possible myocardial depressant effects with lesser amounts of peripheral vasodilation.
What is the difference in dihydropyridine and non dihydropyridine calcium channel blockers what conditions are they used to treat?
The dihydropyridines are more vascular selective and the non-dihydropyridines are more myocardial selective and tend to reduce the heart rate. Further important differences are between short- and long-acting forms of the calcium channel antagonists.
What does non-dihydropyridine mean?
Nondihydropyridines are one of the different types of calcium channel blockers; they act mainly on the heart with less effect on blood vessels. They have a greater depressive effect on cardiac conduction and contractility but are less potent vasodilators than other types of calcium channel blockers (dihydropyridines).
When do you use dihydropyridine and Nondihydropyridine?
Dihydropyridine CCBs (nifedipine and amlodipine) primarily act on vascular smooth muscles. Nondihydropyridine CCBs (verapamil > diltiazem) primarily act on the heart.
What are the two types of calcium channel blockers?
What are the different types? There are two distinct chemical classes of CCBs: the dihydropyridines (such as nifedipine and amlodipine) and the nondihydropyridines (diltiazem and verapamil).
Is amlodipine a DHP?
Amlodipine and barnidipine in the third generation of DHP L-type Ca2+ channel blockers are clinical examples for this scenario. Dihydropyridine CCB amlodipine is the most frequently prescribed and efficacious in the monotherapy for hypertension compared with other classes of CCBs.
What can replace 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)
Is lacidipine a dihydropyridine?
Lacidipine (Caldine, Lacimen, Lacipil, Midotens, Motens) is a once-daily, orally-administered, lipophilic dihydropyridine calcium antagonist with an intrinsically slow onset of activity, resulting in a lack of reflex tachycardia.
What are the different types of dihydropyridines?
They often classify into two major categories, either non-dihydropyridines or dihydropyridines. The non-dihydropyridines include verapamil, a phenylalkylamine, and diltiazem, a benzothiazepine. The dihydropyridines include many other drugs, most of which end in “pine” (i.e., amlodipine and nicardipine).
What is dihydropyridine used to treat?
Dihydropyridine: Think Amlodipine and Nifedipine (-dipine) They act through systemic vascular vasodilation of arteries. Can be used to treat angina. NOTE: can cause hypotension and cause reflex tachycardia (this is bad for patients with ischemic symptoms)
What is the difference between calcium channel blockers and dihydropyridines?
Dihydropyridines are a type of calcium channel blocker (CCB), which refer to a group of medications that block calcium channels located in the muscle cells of the heart and arterial blood vessels, thereby reducing the entry of calcium ions into the cell.
What are the side effects of non-dihydropyridines?
Adverse Effects Non-dihydropyridines may cause constipation, worsening cardiac output, and bradycardia. Dihydropyridines may lead to lightheadedness, flushing, headaches, and peripheral edema. The peripheral edema is likely related to the redistribution of fluid from the intravascular space to the interstitium.
