However, most antidepressant treatments do not directly enhance DA neurotransmission, which may contribute to residual symptoms, including impaired motivation, concentration, and pleasure. [ 21 ] Preclinical and clinical research indicates that drugs inhibiting the reuptake of all three of these neurotransmitters can produce a more rapid onset ...
At moderate doses (>150 mg/day), it acts on serotonergic and noradrenergic systems, whereas at high doses (>300 mg/day), it also affects dopaminergic neurotransmission. [22] At small doses, venlafaxine has also been shown to be effective in treating vasomotor symptoms (hot flashes and night sweats) of menopause.
Behavioral neuropharmacology focuses on the study of how drugs affect human behavior (neuropsychopharmacology), including the study of how drug dependence and addiction affect the human brain. [2] Molecular neuropharmacology involves the study of neurons and their neurochemical interactions, with the overall goal of developing drugs that have ...
There may also be imbalances in mood-regulating neurotransmitters (brain chemicals) like dopamine and serotonin. But this isn’t well understood, either. ... Illicit drug use and substance abuse ...

Medications are used to reverse the symptoms of extrapyramidal side effects caused by antipsychotics or other drugs, by either directly or indirectly increasing dopaminergic neurotransmission. The treatment varies by the type of the EPS, but may involve anticholinergic agents such as procyclidine, benztropine, diphenhydramine, and trihexyphenidyl.
An implicit premise in neuropsychopharmacology with regard to the psychological aspects is that all states of mind, including both normal and drug-induced altered states, and diseases involving mental or cognitive dysfunction, have a neurochemical basis at the fundamental level, and certain circuit pathways in the central nervous system at a higher level.
