WebEpinephrine does not have its own receptors. Instead, since its chemical composition resembles norepinephrine very closely, epinephrine stimulates norepinephrine receptors both in the brain as well as peripherally. In fact, while norepinephrine is primarily a neurotransmitter, epinephrine is primarily a hormone. WebThese include the endogenous ligands for these receptors, norepinephrine, and epinephrine, which also bind to beta adrenoceptors. Some agents, such as the classical adrenoceptor antagonists phentolamine and phenoxybenzamine, are considered to be non-selective in that the binding with somewhat similar affinities to both alpha-1 and alpha-2 … flying with someone else\u0027s medication
