Pramipexole is a highly active non-ergot D 2-like receptor agonist with a higher binding affinity to D 3 receptors rather than D 2 or D 4 receptors. The mechanism of action of pramipexole is mostly unknown, it is thought to be involved in the activation of dopamine receptors in the area of the brain where the striatum and the substantia nigra ...
Dopamine receptors are a class of G protein-coupled receptors that are prominent in the vertebrate central nervous system (CNS) and are implicated in many neurological processes, including motivational and incentive salience, cognition, memory, learning, and fine motor control, as well as modulation of neuroendocrine signaling.
Mephentermine is thought to act as a releasing agent of norepinephrine and dopamine. [4] It is described as an indirectly acting sympathomimetic, cardiac stimulant, adrenergic, vasoconstrictor, antihypotensive agent, and psychostimulant. [1] [2] [8] [4] Its sympathomimetic effects are mediated by indirect activation of α-and β-adrenergic ...
Serotonin–dopamine releasing agents (SDRAs), for instance 5-chloro-αMT, are less common and are not selective for dopamine release, but have also been developed. [9] [14] Tryptamines like 5-chloro-αMT are the only known releaser scaffold that consistently release dopamine more potently than norepinephrine. [15]
Examples of sympathomimetic effects include increases in heart rate, force of cardiac contraction, and blood pressure. [1] The primary endogenous agonists of the sympathetic nervous system are the catecholamines (i.e., epinephrine [adrenaline], norepinephrine [noradrenaline], and dopamine), which function as both neurotransmitters and hormones.
Rotigotine acts as a non-selective agonist of the dopamine D 1, D 2, D 3, and, to a lesser extent, D 4 and D 5 receptors, with highest affinity for the D 3 receptor. [15] In terms of affinity , rotigotine has 10-fold selectivity for the D 3 receptor over the D 2 , D 4 , and D 5 receptors and 100-fold selectivity for the D 3 receptor over the D ...

Amphetamine, the prototypical NDRA.. A norepinephrine–dopamine releasing agent (NDRA) is a type of drug which induces the release of norepinephrine (and epinephrine) and dopamine in the body and/or brain.
