MeSH definition : An alpha-adrenergic sympathomimetic amine, biosynthesized from tyramine in the CNS
and platelets and also in invertebrate nervous systems. It is used to treat hypotension
and as a cardiotonic. The natural D(-) form is more potent than the L( ) form in producing
cardiovascular adrenergic responses. It is also a neurotransmitter in some invertebrates.;
