Adrenergic receptors dopamine interaction

Dopamine is a unique adrenomimetic drug in that it exerts its cardiovascular actions by (1) releasing norepinephrine from adrenergic neurons, (2) interacting with a-and (3i-adrenoceptors, and (3) interacting with spe-cihc dopamine receptors. [Pg.103]

Does Dopamine Interact with Beta- or AlPha-adrenergic receptors ... [Pg.11]

The bovine parathyroid gland also possesses an alpha-adrenergic receptor (16). However, it seems improbable that an interaction between dopamine and the alpha-adrenergic receptor accounts for the physiological and biochemical effects of dopamine upon this tissue. Phentolamine, an alpha-adrenergic antagonist, has no effect on... [Pg.11]

Figure 8. Representation of the interaction between CRF, -adrenergic, and dopaminergic (DA.) receptors in the control of pars intermedia cell activity. The CRF and / -adrenergic receptors stimulate adenylate cyclase activity through interaction with the Ns-GTP-binding component. Dopamine, on the other hand, interacts with the Ni-GTP-binding component, causing inhibition of basal as well as CRF- and f3-adrenergic-induced adenylate cyclase activity. Figure 8.

In SKF 38393 and related compounds may prevent interaction with adrenergic receptors and lead to the observed dopamine receptor selectivity (35). [Pg.213]

Catecholamines exert their effects through specific receptors on the target cell surface. However, the effects elicited depend on the type or subtype of receptor with which they interact. There are three types of catecholamine receptor dopamine, a-adrenergic, and )S-adrenergic. Each of these consists of at least two or more subtypes, which differ with respect to ligand affinity, tissue distribution, postreceptor events, and drug antagonists (Table 32-3). [Pg.763]

Ergonovine (Ergotrate Maleate) Induce uterine smooth muscle contraction. Blocks adrenergic receptors, causes vasoconstriction, interacts with other receptors (dopamine and tryptamine).
