Negative inotropic agents decrease myocardial contractility and are used to decrease cardiac workload in conditions such as angina. While negative inotropism may precipitate or exacerbate heart failure in the short term, certain beta blockers (e.g. carvedilol , bisoprolol and metoprolol ) have been believed to reduce long-term morbidity and ...

An antihypotensive, also known as vasopressor, is an agent that raises blood pressure by constricting blood vessels, thereby increasing systemic vascular resistance.This is different from inotropes which increase the force of cardiac contraction.
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
Although both vasopressors, vasopressin and epinephrine differ in that vasopressin does not have direct effects on cardiac contractility as epinephrine does. [18] Thus, vasopressin is theorized to be of increased benefit over epinephrine in cardiac arrest due to its properties of not increasing myocardial and cerebral oxygen demands. [18]
A cardiac stimulant is a drug which acts as a stimulant of the heart – e.g., via positive chronotropic action (increased heart rate) and/or inotropic action (increased myocardial contractility). They increase cardiac output (the amount of blood pumped by the heart over time).
V 2 receptor (V 2 R) differs from V 1 R primarily in the number of sites susceptible to N-linked glycosylation; the V 1 R has sites at both the amino-terminus and at the extracellular loop, whereas the V 2 R has a single site at the extracellular amino-terminus.
(vasoconstriction and mydriasis; used as vasopressors, nasal decongestants and during eye exams). Selected examples are: Adrenoswitch-1 (photoswitchable partial α 1 agonist and light-controlled mydriatic) [1] Methoxamine; Midodrine; Metaraminol; Phenylephrine [2] Amidephrine [3] Sdz-nvi-085 [104195-17-7].
