Abstract:
Background: Schizophrenia is a chronic disease with acute psychotic symptoms,
which is having frequent recurrence. Paliperidone palmitate (PP) is a second-generation antipsychotic
drug to treat schizophrenia.
Aims: The aim of the study was to prepare lyophilized nanoemulsifying drug delivery system
(NEDDS) of paliperidone (PD).
Objectives: The primary objective of the current research work was to develop a lyophilized
nanoemulsifying drug delivery system (NEDDS) of paliperidone (PD) to improve its oral bioavailability
and stability.
Methods: Optimization using D-Optimal Mixture Design DMD) was conducted, and optimized
NEDDS was further lyophilized to improve stability. The lyophilized optimized NEDDS was further
evaluated for biopharmaceutical evaluation.
Results: A saturation solubility study revealed Peceol, Tween 80, and Plurol Olique CC497 as
suitable candidates for oil, surfactant, and co-surfactant, respectively. Optimized NEDDS of PD
showed mean globule size (MGS) of 185 nm, PDI of 0.27 and cumulative % drug release within
15 min Q15 of 86.6%. Lyophilized optimized NEDDS was found to have no significant change in
quality attributes within the stability study period. A pharmacokinetic study revealed more than
two-fold increases in bioavailability for lyophilized optimized NEDDS.
Conclusion: Hence, lyophilized NEDDS of PD can be used as an effective approach for the improvement
of oral bioavailability and stability.
