  2. Stimulant - Wikipedia

    en.wikipedia.org/wiki/Stimulant

    The sympathetic nervous system is a part of the nervous system that prepares the body for action, such as increasing the heart rate, blood pressure, and breathing rate. Stimulants can activate the same receptors as the natural chemicals released by the sympathetic nervous system (namely epinephrine and norepinephrine) and cause similar effects. [7]

  3. Sympathomimetic drug - Wikipedia

    en.wikipedia.org/wiki/Sympathomimetic_drug

    Sympathomimetic drugs (also known as adrenergic drugs and adrenergic amines) are stimulant compounds which mimic the effects of endogenous agonists of the sympathetic nervous system. Examples of sympathomimetic effects include increases in heart rate, force of cardiac contraction, and blood pressure. [1]

  4. Cardiac stimulant - Wikipedia

    en.wikipedia.org/wiki/Cardiac_stimulant

    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).

    en.wikipedia.org/wiki/Cardiotonic_agent

    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

  9. Beta-adrenergic agonist - Wikipedia

    en.wikipedia.org/wiki/Beta-adrenergic_agonist

    Increased heart rate and heart muscle contraction are associated with the β1 receptors; however, β 2 cause vasodilation in the myocardium. [citation needed] β3 receptors are mainly located in adipose tissue. [5] Activation of the β 3 receptors induces the metabolism of lipids. [6]
