Despite different clinical guidelines, AP is a common pharmacological strategy as it is shown in our study and in the reviewed literature. Data in our study indicate that the observed rates of AP cannot exclusively be attributed to the treatment of patients with clozapine-resistant schizophrenia.

The aim of the study was to describe the psychopharmacological treatments received by inpatients diagnosed with spectrum disorders schizophrenia and other psychotic disorders in Dr. Rodriguez Lafora Hospital. It is an observational, descriptive and retrospective study. We collected information about patients aged 18 to 64 who were hospitalized during the month of January of 2015 in the acute psychiatric hospitalization by Selene software. We reviewed treatments and number of psychiatric re-hospitalization six months later and we analyzed the results by SPSS software. From a sample of 51 inpatients, 15 of them were diagnosed with disorders of the spectrum of schizophrenia and other psychotic disorders. Of the patients, 13.3% was treated with haloperidol, 26.7% with olanzapine, 26.7% with risperidone although it was modified by paliperidone in mental health center, 6.7% with quetiapine, 6.7% with amisulpride, 13.3% with oral paliperidone and 13.3% patients with intramuscular paliperidone. Of these, 40% are readmitted to hospital. Patients were readmitted due to ineffectiveness and adverse effects of haloperidol, olanzapine, risperidone. 73.3% of inpatients were treated with monotherapy. Of the patients, 26.7% were treated with polytherapy, who received olanzapine, risperidone and amisulpride. It would be important to use psychoactive substances that allow monotherapy to reduce adverse effects and psychiatric re-hospitalization.Disclosure of interestThe authors have not supplied their declaration of competing interest.
