Conclusion
The combination of liponiosomes and niosomes in the form of LNHs has the potential to be an effective nano-drug delivery vehicle for RPG.
Methods
The development of RPG-loaded LNHs was performed using the reverse ethanol injection method based on the 23 factorial design to explore the potential of various variables on the encapsulation efficiency (EE%) and % RPG released after 12 h (Q12h). Further in vitro characterization tests and in vivo study were also performed on the optimal RPG-loaded LNHs.
Purpose
The current study sought to create novel deformable liponiosomal hybrids (LNHs) as a viable RPG delivery system. Repaglinide (RPG) is an effective anti-hyperglycemic drug. However, its limited solubility may limit its therapeutic applicability. LNHs are a potential liposome-niosome combination. Using phospholipids and non-ionic surfactants together improves their functionality in regulating drug release and increasing their permeability and stability. Materials and
Results
After investigating how the examined independent factors could affect significantly both the EE % and Q12h, F7 was selected as the optimal liponiosomal formulation. F7 showed 87.07 ± 2.27 EE% and 94.32 ± 1.25 Q12h. F7 demonstrated higher permeability and stability than the corresponding liposomes and niosomes. Furthermore, F7 demonstrated greater hypoglycemic efficacy and bioavailability than pure RPG.
