There is a need for a more balanced assessment of the benefits and risks associated with benzodiazepine use, particularly considering pharmacokinetic profile of the drugs to ensure that patients, who would truly benefit from these agents, are not denied appropriate treatment. An optimal pharmacological approach involving an integrative pharmacokinetic and pharmacodynamic optimization strategy would ensure better treatment and personalization of anxiety disorders. So it would be desirable for the development of new anxiolytic drug(s) that are more selective, fast acting and free from the unwanted effects associated with the traditional benzodiazepines as tolerance or dependence.

The results of this study confirm the efficacy of quetiapine on both anxious and depressive symptoms. Norquetiapine has a specific effect on anxiety and depressive symptoms, showing a correlation between plasma concentrations and clinical efficacy only in patients with bipolar depression.

The diagnosis of psychotic disorder is a poor predictor of aggression in a sample of psychiatric patients. Other clinical and non-clinical variables are associated to aggression before hospitalisation: they include drug abuse, involuntary admission status, general severity of symptoms, and diagnosis of personality disorder.

In the present study we extract clusters of symptoms in acute hospitalized psychotic patients during a re-exacerbation phase, using factor analysis of BPRS-E. We aim to investigate the relative contribution of each symptom dimension in predicting the severity of symptoms at discharge, the length of acute hospitalization, and the occurrence of aggressive behaviours during acute hospitalization. The data are drawn from a prospective, naturalistic, observational study of 183 patients with Psychotic Disorders consecutively admitted to a psychiatric ward, during a re-exacerbation phase. General symptomatology has been measured through BPRS-E at admission and at discharge. Statistical analyses include principal component analysis and multiple linear regression.We found symptoms of acute psychosis disorder to cluster together in four distinct domains, labelled "Excitement/Activation", "Positive symptoms", and "Negative symptoms", and "Depression/Anxiety". Excitement/activation was the dimension most associated with occurrence of aggressive behaviours and severity of psychopathological symptoms at discharge. The negative symptoms dimension, also, predicted the severity of symptoms at discharge. Positive and negative symptoms dimensions were both predictors of duration of hospitalization. The depressive dimension was significantly associated only to self-aggression. These data indicate that during acute hospitalization due to re-exacerbation of psychosis each symptom dimension has a specific impact on distinct measures of outcome.

Our data reveal the efficacy of OLZ-LAI in maintenance treatment of schizophrenia at lower dosages also in comparison with that of oral therapy. OLZ-LAI seems to be useful for guaranteeing constant PL of the drug. A lesser variation of PL was the most predictable factor associated with maintenance of clinical benefit.
