Paliperidone palmitate in short- and long-term treatment of schizophrenia.

Abstract

Poor adherence to treatment remains a major problem in the management of patients with schizophrenia. In the 60s, first generation antipsychotics in depot formulation have been introduced on the market with the aim to improve adherence to therapy. However, the limited effectiveness on negative symptoms and the tendency to induce extrapyramidal side effects has limited their use. Currently there are five second-generation antipsychotic long-acting formulations and the use of these drugs has definitely changed perspective: they are no more restricted as compounds intended to improve compliance, but they can be considered first-line drugs with proven efficacy and good tolerability. In this narrative review the efficacy and tolerability of paliperidone palmitate, as well as the economic impact of the use of this particular molecule, have been evaluated in the short- and long-term treatment of schizophrenia. Taking into account the results of different studies, paliperidone, especially in his long-acting formulation, can be considered a viable and effective treatment for patients with schizophrenia, both in the short- and in the long term.
