The choice of agent depends largely on specific pharmacological effects of individual agents with respect to the condition. One of the most important factors affecting inotropic state is the level of calcium in the cytoplasm of the muscle cell. Positive inotropes usually increase this level, while negative inotropes decrease it.
Negative inotropes improve left ventricular (LV) obstruction by decreasing LV ejection acceleration and hydrodynamic forces on the mitral valve. Disopyramide's particular efficacy is due to its potent negative inotropic effects; in head-to-head comparison, it is more effective for gradient reduction than either beta-blocker or verapamil.

It is advised that those using isradipine not take dolasetron (Anzemet), as both agents can cause a dose-dependent PR interval and QRS complex prolongation. [4]Itraconazole (Onmel/Sporanox) exhibits a negative inotropic effect on the heart and thus could spur an additive effect when used concomitantly with isradipine.
Cardiotonic agents, also known as cardiac inotropes or stimulants, have a positive impact on the myocardium (muscular layer of the heart) by enhancing its contractility. . Unlike general inotropes, these agents exhibit a higher level of specificity as they selectively target the myocar
Negative cardiac inotropes; Central agents; Mechanical device; Discontinuation of medications known to lower blood pressure may be helpful, but stopping antihypertensive drugs can also be dangerous in some people. Taking antihypertensive drugs may worsen the syncope, as the hypertension may have been the body's way to compensate for the low ...
(For example, if you’re experiencing anhedonia on a semaglutide, you can switch to a tirzepatide, which is thought to have less of an impact on people’s mood, says Dr. Russo.)
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.
