Sympathomimetic Amine
Sympathomimetic amines (pronunciation: sim-puh-tho-mim-uh-tik uh-meen) are a class of pharmaceutical drugs that mimic the effects of the sympathetic nervous system. The term is derived from the Greek words "sympatheia" meaning "sympathy" and "mimesis" meaning "imitation".
Definition
Sympathomimetic amines are drugs that mimic the effects of neurotransmitters released by the sympathetic nervous system. These neurotransmitters include norepinephrine and epinephrine, also known as adrenaline.
Mechanism of Action
Sympathomimetic amines work by stimulating the adrenergic receptors, which are found on the cells of the heart, lungs, and other organs. This stimulation can increase heart rate, constrict blood vessels, and open up the airways, among other effects.
Uses
Sympathomimetic amines are used in the treatment of a variety of conditions, including asthma, hypotension, and certain types of shock. They can also be used to prolong the effects of local anesthesia.
Side Effects
Common side effects of sympathomimetic amines include increased heart rate, high blood pressure, and anxiety. In rare cases, they can cause severe side effects such as heart attack or stroke.
