Second generation long acting injectable antipsychotics supply gradually the portfolio of the agents available for the treatment of schizophrenia. The first preparation (risperidon microspheres) has been approved by FDA already in 2003, the last one (aripiprazol monohydrate once in two months) even in the last year. Compared to the first generation their great advantage is in better tolerability and the potential to improve affective symptoms among others. Recently new preparations with longer interval (2 or 3 months) have been introduced. Second generation LAI antipsychotics are characterized with more precisely defined pharmacokinetic profiles and mostly they don´t require p. o. supplementation. These properties shift the potential use towards earlier phases of treatment of psychotic episodes. Currently 6 types of atypical LAI antipsychotics are available which differ in technology of manufacturing. The presented article summarizes the characteristics of individual preparations.

Keywords: atypical antipsychotics, long acting injections, pharmacokinetics, schizophrenia, plasma levels.
