Preparations of different chemical groups currently represent sleeping pills. Barbiturates, which used to be the main sleeping pills for a long time, began to lose their leading importance.
Barbiturates have some disadvantages. The sleep they cause is different from the natural one: they facilitate the onset of sleep (falling asleep), but its structure is the changed-the ratio of the fast (paradoxical, desynchronized) and slow (orthodox, synchronized) sleep phases. Often the dream becomes intermittent, with an abundance of dreams, nightmares.
The hypnotics of the benzodiazepine group have a certain degree of advantage over barbiturates – they are better tolerated. However, neither by the nature of the caused sleep nor by side effects, they also do not meet the “physiological” requirements. All tranquilizers of the benzodiazepine group have a sedative effect to a certain extent and contribute to the onset of sleep.
Soporifics in dosages exceeding therapeutic may become a threat to life. Therefore, if you decide to take this or that drug for insomnia, carefully read the instructions for use about the symptoms of its overdose.
