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]
The following are medications commonly prescribed cardiac pharmaceutical agents. The specificity of the following medications is highly variable, and often are not particularly specific to a given class. As such, they are listed as are commonly accepted.
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. Some substances do both (e.g. dopamine, dobutamine).
The "vaptan" drugs act by directly blocking the action of vasopressin at its receptors (V 1A, V 1B and V 2).These receptors have a variety of functions, with the V 1A and V 2 receptors are expressed peripherally and involved in the modulation of blood pressure and kidney function respectively, while the V 1A and V 1B receptors are expressed in the central nervous system.
The mechanisms of sympathomimetic drugs can be direct-acting (direct interaction between drug and receptor), such as α-adrenergic agonists, β-adrenergic agonists, and dopaminergic agonists; or indirect-acting (interaction not between drug and receptor), such as MAOIs, COMT inhibitors, release stimulants, and reuptake inhibitors that increase the levels of endogenous catecholamines.
Medications for Depression: An Overview. Antidepressants are a class of medications used very commonly to treat depression. In fact, nearly 13 percent of people 12 and over in the U.S. used ...
Refractive errors, some of the most common types of vision problems, cannot be treated with medication, for example. Instead, glasses, contact lenses, and surgery are used to correct them as ...
It is important to note that certain medications, such as Milrinone and Digoxin, possess overlapping classifications due to their ability to engage multiple mechanisms of action. Their inotropic properties make cardiactonic agents critical in addressing inadequate perfusion , and acute heart failure conditions including cardiogenic shock , as ...
