[Therapy of insomnia]. / La terapia dell'insonnia.

The authors review the neurochemical and electrophysiological features of insomnia, together with the results obtained by various substances. The literature data show that the benzodiazepines (BZ) should be administered for short periods of time, in order to avoid addiction and withdrawal symptoms. For this reason, the authors suggest that, before starting a therapy with such substances, an accurate clinical evaluation should be made and a good knowledge of the pharmacokinetics of the various BZ is essential.
