Dromotropic drugs list
WebVasoactive agents include the following: inotropes are agents that increase myocardial contractility (inotropy) — e.g. adrenaline, dobutamine, isoprenaline, ephedrine. … The term dromotropic derives from the Greek word δρόμος drómos, meaning "running", a course, a race. A dromotropic agent is one which affects the conduction speed (in fact the magnitude of delay ) in the AV node, and subsequently the rate of electrical impulses in the heart. Positive dromotropy increases conduction velocity (e.g. epinephrine stimulation), negative dromotropy decreases velocity (e.g. vagal stimulation).

Web7 nov 1989 · Abstract. Amlodipine is a potent calcium antagonist, inhibiting Ca2+-induced contractions of depolarized rat aorta with an IC50 of 1.9 nM. Unlike nifedipine, it displayed very slow association and dissociation with the calcium channel. The ability of amlodipine to inhibit Ca2+-induced contractions was strongly dependent on the K+ concentration ...
