Uses

  • Dopamine Hydrochloride is an essential biochemical reagent and a vasopressor medication.

  • Clinically, it is primarily used to treat various types of shock, especially those accompanied by decreased myocardial contractility and renal insufficiency.

  • Dopamine Hydrochloride stimulates cardiac β-receptors, increasing myocardial contractility and cardiac output. Simultaneously, it stimulates dopamine receptors and α-receptors, causing vasodilation in the kidney, mesenteric, coronary, and cerebral vessels, leading to increased blood flow and renal blood flow, which enhances glomerular filtration rate and promotes increased urine output and urinary sodium excretion.

Safety

  • Dopamine Hydrochloride is classified as an irritant and requires proper precautions during handling.

  • Its acute toxicity data indicates an LD50 of 2859 mg/kg in rats and 4361 mg/kg in mice.

Storage and Transportation

  • Dopamine Hydrochloride should be stored in a low-temperature, ventilated, and dry environment, away from direct sunlight and high temperatures.

  • During transportation, ensure that the packaging is intact to prevent leakage and moisture.
