Structure:
DrugBank Description: Efonidipine is a calcium channel blocker of the _dihydropyridine class_, commercialized by Shionogi & Co. (Japan). Initially, it was marketed in 1995 under the trade name, _Landel_. The drug has been shown to block T-type in addition to L-type calcium channels . It has also been studied in atherosclerosis and acute renal failure . This drug is also known as NZ-105, and several studies have been done on its pharmacokinetics in animals .
CAS Number: 111011-63-3
Molecular Weight: 631.666
DrugBank Indication: For the treatment of hypertension.
DrugBank Pharmacology: Dihydropyridines (DHPs), act mainly on L-type calcium channels, essentially causing reflex tachycardia, which negatively affects cardiac function. This leads to a decrease in blood pressure and an increase in heart rate. Efonidipine acts on both L-type and T-type calcium channels. Because inhibition of T-type calcium channels in the sinoatrial (SA node) node attenuate reflex tachycardia, this drug favorably affects cardiac pacing. The effect of efonidipine on heart rate deserves special recognition with regard to reflex tachycardia, due to its unique effects in relation to other drugs in its class .
DrugBank MoA: This drug inhibits the L-type and T-type calcium channels, thereby leading to vasodilation and decreased automaticity of the heart. Efonidipine exerts negative chronotropic effects, decreasing heart rate. Acting on SA node cells by inhibiting T-type calcium channel activity, Efonidipine prolongs the late phase-4 depolarization of the sinoatrial node action potential, decreasing heart rate. This is associated with decreased myocardial oxygen demand and increases of blood flow to the coronary arteries and thereby attenuates myocardial ischemia. Efonidipine increases glomerular filtration rate (GFR) without increasing intra-glomerular pressure and filtration fraction . This increase leads to the prevention of renal damage that is normally associated with hypertension. Efonidipine increases the rate of renal sodium excretion via the suppression of aldosterone synthesis and aldosterone secretion from the adrenal glands. Aldosterone-induced renal parenchymal fibrosis is said to be suppressed by efonidipine . L-type calcium channel blockers, such as efonidipine, preferentially dilate afferent arterioles in the kidney, whereas both L-/T-type and L-/N-type calcium channel blockers potently dilate both afferent and efferent arterioles. The distinct actions of calcium channel blockers on the renal microcirculation are demonstrated by changes in glomerular capillary pressure and subsequent renal injury: L-type calcium channel blockers favor an increase in glomerular capillary pressure, whereas L-/T-type and L-/N-type CCBs alleviate glomerular hypertension. This supports the theory that L-Type/T-type calcium channel blockers may be of benefit in renal hypertension . Efonidipine is a long-acting medication due to a low dissociation constant . Recent studies suggest that efonidipine reduces plasma aldosterone levels in patients on regular hemodialysis, which is of additional benefit to the cardiovascular protection by antihypertensive therapy with efonidipine in patients with end-stage renal disease .
