The parent compound is uncommon, [2] but derivatives of 1,4-dihydropyridine are important commercially and biologically. The pervasive cofactors NADH and NADPH are derivatives of 1,4-dihydropyridine. 1,4-Dihydropyridine-based drugs are L-type calcium channel blockers, used in the treatment of hypertension. 1,2-Dihydropyridines are also known ...
Dihydropyridine (DHP) calcium channel blockers are derived from the molecule dihydropyridine and often used to reduce systemic vascular resistance and arterial pressure. Sometimes when they are used to treat angina , the vasodilation and hypotension can lead to reflex tachycardia , which can be detrimental for patients with ischemic symptoms ...
Compared with certain other L-type calcium channel blockers (for example those of the phenylalkylamine class such as verapamil) that have significant action at the heart, the dihydropyridine calcium channel blockers lower blood pressure mainly by relaxing the smooth muscle of the blood vessel walls.

The ratio of CCBs' anti-proteinuria effect, non-dihydropyridine to dihydropyridine was 30 to −2. [13] The anti-proteinuria effect of non-dihydropyridine is due to better selectivity during glomerular filtration and/or a lower perfusion rate through the renal system.
For example, reduction with lithium aluminium hydride yields a mixture of 1,4-dihydropyridine, 1,2-dihydropyridine, and 2,5-dihydropyridine. [102] Selective synthesis of 1,4-dihydropyridine is achieved in the presence of organometallic complexes of magnesium and zinc , [ 103 ] and (Δ3,4)-tetrahydropyridine is obtained by electrochemical ...

Clevidipine is a dihydropyridine L-type calcium channel blocker, highly selective for vascular, as opposed to myocardial, smooth muscle and, therefore, has little or no effect on myocardial contractility or cardiac conduction. It reduces mean arterial blood pressure by decreasing systemic vascular resistance.
