Introduction: We describe the different diseases in which conventional and second generation antipsychotic (APS) prescriptions are made.
Method: Observational, retrospective, multicenter study based on the review of 300 clinical records of public and private sites, hospital and out-patient clinics, located in Salamanca, Vigo, Bilbao, Barcelona, Valencia, Oviedo and Malaga.
Results: The mean age of the population studied was 42 +/- 17 years; 56.6 % were men. Atypical drugs (67 %) were used basically versus classical ones (33 %). Classical APS are basically prescribed in bipolar disorder with/without psychotic symptoms (20.6 %), schizophrenia (18.3%) and delusional disorder (11.5 %). Atypical APS are fundamentally prescribed in schizophrenia (31.5 %), bipolar disorders with/without psychotic symptoms (12.5 %) and other psychotic disorders (8.9 %). When the psychotic disorders are considered by groups (schizophrenia, bipolar disorder with psychotic symptoms, delusional disorder and other psychotic disorders), classical APS are used in 47.4 % and atypical APS in 62.5%. APS were used ((outside the indication)) (off-label) in 32.8%, including resistant depressions, serious obsessive-compulsive disorder and borderline personality disorder, with similar percentages for both conventional and atypical ones. In dementia, atypical APS were used in 5.1 % versus 1.5 % of the conventional ones. The most frequent reasons for prescription of classical APS were control of psychotic symptoms (33.6 %), aggressiveness-agitation (31.3 %), severe insomnia (16 %), impulsivity (6.9 %) and severe anxiety (6.1 %). Atypical APS were preferably used in the control of psychotic symptoms (58.8%) and aggressiveness-agitation (25.5%).
Conclusions: The use of APS basically occurs within their authorized indications (67.2 %). The off-label use (32.8 %) occurs both for the classical as well as atypical APS and occurs in serious diseases in which there are no alternative treatments.
