Name the t Post by: magics on Oct 24, 2012 Dopamine dilates systemic arteries, elevates systolic blood pressure, increases cardiac output, and increases urinary output. It is used in the treatment of shock and is a neurotransmitter in the nervous system. Epinephrine acts as a vasoconstrictor, vasopressor, cardiac stimulant, antispasmodic, and sympathomimetic. Its main function is to assist in the regulation of the sympathetic branch of the autonomic nervous system. Norepinephrine acts as a vasoconstrictor, vasopressor, and a neurotransmitter. It elevates systolic and diastolic blood pressure, increases the heart rate and cardiac output, and increases glycogenolysis.
