Dobutamine is a synthetic sympathomimetic drug used in the treatment of hypotension associated with congestive heart failure, sepsis associated with peritonitis and other life-threatening cases of cardiogenic or hemorrhagic shock[1].

Its primary mechanism is direct stimulation of β1-receptors of the sympathetic nervous system, resulting in increased heart rate and cardiac contractility[2].

This drug is also used as a diagnostic tool with dysautonomia[3].

Recommended dose rates in dogs is 2 - 20 µg/kg/min given as an intravenous constant rate infusion.
