People who don’t respond to levodopa often don’t respond to dopamine agonists. Nausea, vomiting, loss of appetite, malaise, low blood pressure, skin discoloration, visual hallucinations, confusion. May make levodopa-induced dyskinesias worse. Suddenly falling asleep — which may be a hazard.

Main affect is on systolic blood pressure. Dopamine. Low dose, will get vasodilation of the splenic and renal areas. Main use is to keep renal blood flow going. Increase dose, get (1 response, will get increase in systolic blood pressure, stimulate the heart to increase force and rate

Dopamine is the drug of choice for cardiogenic and septic shock and is given by continuous infusion. It raises blood pressure by stimulating the β 1 receptors on the heart to increase cardiac output and α 1 receptors on blood vessels to increase total peripheral resistance.

If the patent has a critically low blood pressure, a blood pressure elevating medication such as dopamine is given. For critically ill patients, thrombolytics are given to break up the clot and restore blood flow to the lung. However, there is a high risk of catastrophic bleeding with thrombolysis.

A. Atropine blocks the parasympathetic (Ach) receptors on the pacemaker cells of the heart. Why would atropine be helpful to someone whose blood pressure is low? [Hint: increasing heart rate will act to increase blood pressure] B. Cocaine is a dopamine agonist. Dopamine is also a precursor (chemically) to epinephrine and norepinephrine.
Dobutamine vs. Dopamine Prescription Treatment for Low Blood Pr…
At low doses, dopamine receptor stimulation predominates, causing renal, mesenteric and coronary blood vessel vasodilation without any significant effect on cardiac output or blood pressure. At infusion rates of 3 to 10 microg/kg/min, β 1 -receptor activation promotes positive inotropic and some chronotropic effects, increasing stroke volume ...

Blocks both dopamine and serotonin receptor sites. Similar side effects to typical anti-psychotics but tardive dyskinesia much reduced. Fewer side effects than typical or first generation anti-psychotics. Rare side effect: agranulocytosis, (dangerously low levels of white blood cells) can be fatal. Pickar et al (1992)
