Introduction: Pharmacological treatment of insomnia in patients with addictions has been hardly investigated and there are few researches about it in an inpatient detoxification. The aim of this study was to describe the outcomes of the pharmacological treatment of insomnia in SUD patients admitted to a detoxification unit in Spain, with a focus on the primary substance of abuse and co-occurring mental disorders. Methods: A quasi-experimental study was conducted in 481 addicted in patients, who were admitted for substances detoxification in Vall d´Hebron University Hospital, Barcelona, Spain, from 2010 to 2015. The patients underwent systematic evaluation of axes I and II psychiatric disorders (SCID-I, SCID-II, and CAADID). Insomnia was evaluated using a night time sleep log. Substance-dependent patients, who had insomnia during hospital detoxification, received a psychotropic medication with hypnotic effect, keeping the regular clinical practice without randomization. Results: At discharge, insomnia was considered to have been alleviated in 63.8% (n = 204) of patients while 36.2% (n = 116) of patients remained with insomnia disturbances. Comparing hypnotic treatments it was observed that mirtazapine and clotiapine were the treatment that corrected the insomnia more frequently. Discussion: Since insomnia is not corrected in all patients, it should be further investigated in medications with hypnotic purpose. Based on the results of this work, randomized clinical trials might be proposed.
