It is considered a second generation version of aripiprazole (Abilify), but has slightly different activity at the serotonin and dopamine receptors which may reduce certain side effects such as restlessness. It might help improve mood symptoms in people with schizophrenia, bipolar disorder, and depression by balancing serotonin and dopamine levels in the brain. [9] It is mainly thought that dopamine agonists help with treating depressive symptoms and disorders by alleviating motor complications, which is one of the main symptoms of Parkinson's disease. MDD is especially burdensome as approved monoamine antidepressant treatments have weeks-long delays before clinical benefit and low remission rates. Unlike clozapine (3) and risperidone (4), which are pure antagonists of dopaminergic and serotonergic receptors, aripiprazole acts as a partial agonist at the serotonin 5-HT 1A receptors and the pre- and postsynaptic dopamine D 2 receptors, and as an antagonist at the serotonin 5-HT 2A receptors [107-109]. 5-HT1A receptors are located pre-synaptically on 5-HT neurons and postsynaptically within the forebrain . This specificity allows it to be effective in treating Parkinson’s disease and restless leg syndrome while potentially reducing the risk of certain side effects associated with broader Quinagolide has actions and uses similar to those of ergot-derived dopamine agonists, but its side-effects differ slightly. Today, we use dopamine agonists as monotherapy or in combination with Sinemet (carbidopa/levodopa). neuint. Animal model studies and clinical case reports also suggested Dec 26, 2014 · Depression: Although most cases of depression are treated with serotonergic drugs, some cases benefit from medications that influence dopamine. Nov 5, 2013 · A number of experimental drugs in pre-clinical or clinical development, including aripiprazole and cariprazine, may act as antidepressants because of their partial agonist activity at dopamine D3 receptors. One of the novel hypotheses of interest to the field was that drugs with dopamine agonist properties might decrease dopamine neurotransmission and have dopamine antagonist-like effects (Tamminga and Carlsson, 2002). Anhedonia has been linked to imbalances in neurotransmitters, which are chemical messengers secreted by nerves. Dopamine agonists are used to treat Parkinson’s disease, depression, restless legs syndrome, attention deficit hyperactivity disorder, low sex drive and hyperprolactinemia. To our knowledge, six studies have investigated the possible effect of adjunctive dopamine agonists in the treatment of refractory depression [8 – 13].

In the 1990s, several studies, mostly from Japan (particularly from a research group at Hokkaido University in Sapporo), reported the efficacy of the ergot alkaloids bromocriptine and pergolide in the treatment of (treatment-resistant) depression. Dopamine is an important neurotransmitter regulating voluntary movement, reward and addictive behavior, moods such as mania and depression, cognition, memory, learning, sleep, and food intake.

Since then, there have been important developments in the study of anhedonia, mainly using the new techniques that neuroimaging made available, which provide very interesting new insights. In cloned human receptors, all three have high affinities for D 2-like dopamine receptors and for 5-HT 1A serotonin receptors (being partial agonists at both), low affinities as full antagonists for histamine H 1 and muscarinic acetylcholine M 1 receptors, and intermediate affinities as full antagonists for many other receptors, including 5-HT 2A and 5-HT 7 (Tables 1 and 2). [67,68] The gold standard for evaluating the efficacy of dopamine agonists in the treatment of depression in PD should therefore be to demonstrate superior efficacy . It can also cause severe anxiety, depression Combining a dopamine agonist and selective serotonin reuptake inhibitor for the treatment of depression: a double-blind, randomized pilot study J Affect Disord . That is, if dopamine’s affinity for a receptor is greater than that of the drug, dopamine would successfully compete with the drug for the receptor if dopamine mine agonists judiciously, warn patients about the risks of DAWS prior to the initiation of dopamine agonist therapy, and follow patients closely for withdrawal symptoms dur-ing dopamine agonist taper. On the other hand, evidence for efficacy of dopamine agonists in the treatment of refractory unipolar major depressive disorder (MDD) is scarce.
