Notes: Amlodipine-d4 is intended for use as an internal standard for the quantification of amlodipine (Item No. 14838) by GC- or LC-MS. Amlodipine is a dihydropyridine L-type calcium channel blocker that selectively inhibits calcium influx in cardiac and vascular smooth muscle.{23674} Acting as a vasodilator, amlodipine reduces blood pressure by relaxing the smooth muscle in the arterial wall, decreasing total peripheral resistance. It inhibits calcium-induced contractions in depolarized rat aorta with an IC50 value of 1.9 nM, displaying a slow rate of association and dissociation in isolated vascular and cardiac tissues.{23674} Amlodipine also demonstrates actions independent of L-type calcium channel blockade by regulating membrane fluidity and cholesterol deposition, stimulating nitric oxide production, acting as an antioxidant, and regulating matrix deposition in vitro and in vivo.{23673} Formulations containing amlodipine have been used in the treatment of hypertension.
