A drug with psychotomimetic (also known as psychotogenic) actions mimics the symptoms of psychosis, including delusions and/or delirium, as opposed to only hallucinations. Psychotomimesis is the onset of psychotic symptoms following the administration of such a drug. Some rarely used drugs of the opioid class have
The treatment of psychosis depends on the specific diagnosis (such as schizophrenia, bipolar disorder or substance intoxication). The first-line treatment for many psychotic disorders is antipsychotic medication, [134] which can reduce the positive symptoms of psychosis in about 7 to 14 days. For youth or adolescents, treatment options include ...
Mephentermine appears to act by indirect stimulation of β-adrenergic receptors through causing the release of norepinephrine from its storage sites. It has a positive inotropic effect on the myocardium. AV conduction and refractory period of AV node is shortened with an increase in ventricular conduction velocity. It dilates arteries and ...
Antipsychotics are drugs used to treat various symptoms of psychosis, such as those caused by psychotic disorders or schizophrenia. Atypical antipsychotics are also used as mood stabilizers in the treatment of bipolar disorder, and they can augment the action of antidepressants in major depressive disorder. [22]
The choice of agent depends largely on specific pharmacological effects of individual agents with respect to the condition. One of the most important factors affecting inotropic state is the level of calcium in the cytoplasm of the muscle cell. Positive inotropes usually increase this level, while negative inotropes decrease it.
Taking a high dose of ADHD drugs is linked to more than five times greater risk of developing psychosis or mania, according to a new study published Thursday in the American Journal of Psychiatry.
In giving glycine to people with PCP-induced psychosis a recovery rate was noted. From there, it was hypothesized that people with psychosis from schizophrenia would benefit from increased glutamate transmission and glycine was added with strong recovery rates noted especially in the area of negative and cognitive symptoms.
The dopamine hypothesis of schizophrenia or the dopamine hypothesis of psychosis is a model that attributes the positive symptoms of schizophrenia to a disturbed and hyperactive dopaminergic signal transduction. The model draws evidence from the observation that a large number of antipsychotics have dopamine-receptor antagonistic effects. The ...
