Amisulpride is approved and used at low doses in the treatment of dysthymia and major depressive disorder. [10] [20] [11] [21] [22] [23] Whereas typical doses used in schizophrenia block postsynaptic dopamine D 2-like receptors and reduce dopaminergic neurotransmission, low doses of amisulpride preferentially block presynaptic dopamine D 2 and D 3 autoreceptors and thereby disinhibit dopamine ...
Lower doses, however, act upon dopamine autoreceptors, resulting in increased dopamine transmission, improving the negative symptoms of schizophrenia. Lower doses of amisulpride have also been shown to have antidepressant and anxiolytic effects in non-schizophrenic patients, leading to its use in dysthymia and social phobias.
The atypical antipsychotics (AAP), also known as second generation antipsychotics (SGAs) and serotonin–dopamine antagonists (SDAs), [1] [2] are a group of antipsychotic drugs (antipsychotic drugs in general are also known as tranquilizers and neuroleptics, although the latter is usually reserved for the typical antipsychotics) largely introduced after the 1970s and used to treat psychiatric ...
Dopamine receptor flow chart. Dopamine receptors are all G protein–coupled receptors, and are divided into two classes based on which G-protein they are coupled to. [1] The D 1-like class of dopamine receptors is coupled to Gα s/olf and stimulates adenylate cyclase production, whereas the D 2-like class is coupled to Gα i/o and thus inhibits adenylate cyclase production.
Moderate dose: headache, nausea, weakness, or anxiety Large dose: loss of consciousness Perfluoroisobutene Gas: colorless Odor: none 1-4 hours Flu-like, also eye, nose, and throat irritation, and chest discomfort, or no symptoms Phosgene Gas: colorless Odor: decaying fruit, fresh-cut grass, 1-4 hours; small doses, 24-48 hours
Neuroleptic-induced deficit syndrome is principally characterized by the same symptoms that constitute the negative symptoms of schizophrenia: emotional blunting, apathy, hypobulia, anhedonia, indifference, difficulty or total inability in thinking, difficulty or total inability in concentrating, lack of initiative, attention deficits, and desocialization.

Another method is "defined daily dose" (DDD), which is the assumed average dose of an antipsychotic that an adult would receive during long-term treatment. [15] DDD is primarily used for comparing the utilization of antipsychotics (e.g. in an insurance claim database), rather than comparing therapeutic effects between antipsychotics. [ 15 ]
Visceral fat is the type of fat that surrounds your internal organs in your abdomen. It can be particularly worrisome because it's housed in places where fat shouldn't be stored in excess. While ...
