octopamine has been researched along with Cirrhosis, Liver in 15 studies
Octopamine: 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.
octopamine : A member of the class of phenylethanolamines that is phenol which is substituted at the para- position by a 2-amino-1-hydroxyethyl group. A biogenic phenylethanolamine which has been found to act as a neurotransmitter, neurohormone or neuromodulator in invertebrates.
