Psychotropic drugs are a group of medicinal substances that affect mental processes, acting primarily on higher nervous activity. Psychotropic drugs are classified according to their clinical impact and divided into three groups: neuroleptics, antidepressants, psychotomimetic drugs.
Mental disorders, accompanied by delirium, hallucinations, intense anxiety or fear, as well as states with a predominance of excitement – catatonic, manic, states of altered consciousness are treated primarily with neuroleptics. Mental disorders, manifested by inhibition, – primarily various depressive syndromes – are treated with antidepressants.
Since a significant number of mental disorders usually combine the phenomena of excitation and inhibition, in practice, combined treatment with neuroleptics and antidepressants is more often used. The ratio of doses varies depending on the change in the mental state of the patient.
Most psychotomimetic drugs cause short-term psychoses in a person, accompanied by bright visual and auditory hallucinations, euphoria, impaired perception of the surrounding, body scheme, as well as vegetative disorders (pupil dilating, drooling, sweating, tachycardia, fluctuations in blood pressure, dyspnea).
