"WebAug 10, 2024 · Dobutamine, a synthetic catecholamine, acts on β 1 receptors increasing cardiac contractility. It also has α 1 and β 1 effects on peripheral vasculature resulting in vasodilatation at lower doses, thus increasing cardiac output. At doses above 5mcg/kg/min it can result in vasoconstriction. It is usually used with an inopressor in cariogenic shock. " - Dobutamine and afterload
