Memantine was shown in a study to act as an agonist at the dopamine D 2 high receptor with equal or slightly higher affinity than to the NMDA receptors. [41] However, the relevance of this action may be negligible, as studies have shown very low affinity for binding to D 2 receptors in general. [42]
Drug titration is the process of adjusting the dose of a medication for the maximum benefit without adverse effects. [ 1 ] When a drug has a narrow therapeutic index , titration is especially important, because the range between the dose at which a drug is effective and the dose at which side effects occur is small.

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.
Dopamine, sold under the brand name Intropin among others, is a medication most commonly used in the treatment of very low blood pressure, a slow heart rate that is causing symptoms, and, if epinephrine is not available, cardiac arrest. [4] In newborn babies it continues to be the preferred treatment for very low blood pressure. [5]
Dopamine therapy is the regulation of levels of the neurotransmitter dopamine through the use of either agonists, or antagonists; and has been used in the treatment of disorders characterized by a dopamine imbalance. Dopamine replacement therapy (DRT) is an effective treatment for patients with decreased levels of dopamine.
Solriamfetol is a norepinephrine–dopamine reuptake inhibitor (NDRI). [1] It binds to the dopamine transporter (DAT) and the norepinephrine transporter (NET) with affinities (K i) of 14.2 μM and 3.7 μM, respectively. [1] It inhibits the reuptake of dopamine and norepinephrine with IC 50 values of 2.9 μM and 4.4 μM, respectively. [1]
Dopamine is used as a neurotransmitter in most multicellular animals. [135] In sponges there is only a single report of the presence of dopamine, with no indication of its function; [136] however, dopamine has been reported in the nervous systems of many other radially symmetric species, including the cnidarian jellyfish, hydra and some corals ...
ALTO-100 is orally active and is administered orally in the form of tablets. [1] Peak levels of ALTO-100 are reached 1 to 2 hours after administration. [1] Area-under-the-curve levels of ALTO-100 increase linearly across a dosing range of 40 mg one to three times per day (i.e., 40–120 mg/day). [1]
