Lack of relationship between plasma levels of escitalopram and QTc-interval length.

Despite safety concerns raised by the European Medicines Agency (EMA), evidence supporting QT-lengthening effects of escitalopram is far to be conclusive. We aimed to evaluate the relationship between escitalopram plasma levels (Escit-PL) and corrected QT-interval length (QTc-length) in 91 outpatients recruited from a hospital setting. Fifteen patients had an abnormally prolonged QTc-interval, and 3 had QTc-intervals ≥500 ms.

Neuropsychological effects of maintenance treatment with Clozapine in Treatment-Resistant Psychotic Disorder.

Introduction: Clozapine is a second-generation antipsychotic drug that is mainly prescribed for treatment-resistant psychotic disorder. It is known to have several undesirable side effects, including cognitive functional complaints, such as memory or attention. The aim of this work is to study if reduction of the dosage within the therapeutic margins could improve cognitive performance of Clozapine treated patients.
