The receptors most relevant to the pharmacology of vasopressors are adrenoceptors. Adrenoceptors, sometimes referred to as adrenergic receptors, interact with norepinephrine, epinephrine, and chemically similar drugs (called adrenomimetic, adrenergic, or sympathomimetic agents).
Included in the list of sympathomimetic drugs are beta-adrenoceptor agonists and alpha-adrenoceptor agonists. Some sympathomimetics stimulate the release of norepinephrine from sympathetic nerves in addition to their receptor agonist activities.ncluded in the list of sympathomimetic drugs are beta-adrenoceptor agonists and alpha-adrenoceptor agonists.
