Drugs of this type are divided into 2 groups major: minor tranquilizers and major tranquilizers.
Tranquil minors
These drugs are certainly less dangerous than the barbiturates, whose place they took. Of course, it is possible that taken together with other drugs there is a potentiating effect. Ataxia, the loss of consciousness and respiratory depression generally respond to a symptomatic treatment, whereas if the ingestion occurred a few hours earlier it may gastric emptying be helpful.
Tranquillant majors
They have greater effects than minor tranquilizers and are capable of causing various disturbances in the functions of the body. The presence of these drugs in the urine can be ascertained by colorimetric reaction. The diagnosis is deduced from the history, seen together with the symptom complex. In addition to usual treatment, it may be necessary to quell symptoms with benzotropin. forced diuresis, hemodialysis, and hemoperfusion are unable to promote the elimination of these drugs from the body.
