Objectives:
Psoriasis is a chronic inflammatory, T-lymphocyte immune-mediated skin disease. In this study, skin-permeating nanolipid carriers (NLCs) of Methotrexate (MTX) and Baicalin (BL) were formulated. This further gave formulation of nano-lipid encapsulated carriers for dual-drug delivery of the hydrophilic and hydrophobic drugs through the liposomal gel.
Materials And Methods:
Optimization of the formulation of NLCs was performed and characterized by determining their particle size, drug permeation, skin irritation, drug loading capacity, stability, in vitro drug release behavior, and in vitro cellular viability. Ex vivo skin permeation and in vivo psoriatic efficiency were also evaluated and compared.
Results:
Results revealed that the amount of MTX permeating the skin was 2.4 to 4.4 fold greater for dual-drug s than for single NLCs. The optimized dual-drug loaded NLCs had an average particle size (150.20 ± 3.57 nm) and polydispersity index (0.301 ± 0.01) and high entrapment (86.32 ± 2.78% w/w). The MTX nanoparticles exhibit a positive Zeta potential of 38.6 mV. The psoriasis area and severity index scoring showed the lowest skin erythema, skin thickness and scaling. MTX-BL NLCs were inhibited the expression of inflammatory cytokines (tumor necrosis factor-alpha, and interleukin-17) .
Conclusion:
It can be concluded that newer targeting strategies for NLCs for dual-drug delivery of nano-lipid carriers could be administered topically for the treatment of psoriasis.
