Lipid core nanocapsules (LNC) have been extensively studied as a new treatment strategy to improve therapeutic effects of antipsychotic drugs. We investigated the efficacy of quetiapine LNCs (QLNCs) on the poly(i:c) model of schizophrenia in both male and female rats using the pre-pulse inhibition of startle response (PPI) test paradigm after evaluating the outcomes of three different poly(i:c) doses administered to pregnant damns at GD15 on neurodevelopmental outcomes of maternal immune activation (MIA) in adult offspring. QTP solution was not capable of producing a reversal in the sensorimotor gating-disruptive effect caused by the prenatal poly(i:c) exposure. The same dose of QTP given as QLNCs significantly improved PPI-impairment. This is the first study reporting the restoration of the PPI deficits in a neurodevelopmental model of SCZ using LNCs. This is a promising delivery system strategy to improve antipsychotic effects contributing to the development of better SCZ pharmacological treatments.
