Inotropes act on your cardiomyocytes, the cells in your heart muscle. Positive inotropic drugs help your heart beat with more force. Negative inotropic drugs tell your heart muscles to contract with less force.
WebVasoactive medications that have positive inotropic effects, which increase CO, are known as inotropes. Examples of inotropes include dobutamine, milrinone, and isoproterenol. Dobutamine is a beta-1 adrenergic agonist and causes increased cardiac contractility, heart rate, and oxygen delivery. Combined, these lead to an increase in CO. WebIonotropic receptors, also called ligand-gated channels, are ion channels that are opened by the binding of neurotransmitters. Voltage-gated channels are opened by the membrane potential of the cell reaching threshold. Both types of channels allow ions to diffuse down their electrochemical gradient.
