Dopamine hydrochloride, a pseudoepinephrine, stimulates the -receptor and dopamine receptor directly. It has the following
effects: first, by stimulating the dopamine receptors in the kidney and mesenteric vessels, it causes the blood vessels in this
area to dilate and increase the renal blood flow. 2. It can enhance the contractile force of myocardium, but not significantly
increase the heart rate, and can be used in anti-shock therapy. 3. In large doses, the peripheral blood vessels can be contracted
to increase the total peripheral resistance and blood pressure. It is used for toxic, hemorrhagic or cardiogenic shock, especially
for patients with weakened cardiac contractility and decreased urine output, but the blood volume has been made up. Combined with
diuretics, can be used in patients with acute renal failure.
Dopamine HCl is a catecholamine neurotransmitter present in a wide variety of animals,And a dopamine D1-5 receptors
agonist.Target: Dopamine ReceptorDopamine (or 3,4-dihydroxyphenethylamine) is a neuroendocrine transmitter in the
catecholamine and phenethylamine families that plays a number of important roles in the brain and bodies of humans.
Several important diseases of the nervous system are associated with dysfunctions of the dopamine system. Outside
the nervous system, dopamine functions in several parts of the body as a local chemical messenger. In the blood vessels,
it inhibits norepinephrine release and acts as a vasodilator; in the kidneys, it increases sodium excretion and urine output;
in the pancreas, it reduces insulin production; in the digestive system, it reduces gastrointestinal motility and protects
intestinal mucosa; and in the immune system, it reduces the activity of lymphocytes. A variety of important drugs work
by altering the way the body makes or uses dopamine. Dopamine itself is available for intravenous injection: although
it cannot reach the brain from the bloodstream, its peripheral effects make it useful in the treatment of heart failure
or shock, especially in newborn babies. L-DOPA, the metabolic precursor of dopamine, does reach the brain and is
the most widely used treatment for Parkinson's disease.
