Description:
Background: The JAK-STAT pathway has been revealed to play a crucial role in the dysregulation
of immune responses in autoimmune skin disorders. Ruxolitinib, a selective inhibitor of JAK1
and JAK2, potently suppresses cytokine signaling.
Methods: A topical emulgel containing ruxolitinib nanoliposome (RuxoLip) was prepared by
the thin-film hydration method. Subsequently, its physicochemical characteristics were evaluated
at 25±2°
C/60±5% RH for 12 months. RuxoLip was assessed based on particle characteristics,
Scanning Electron Microscopy (SEM), entrapment efficiency (EE), drug loading (DL), and
Differential Scanning Calorimetry. The pH, density, viscosity, microbial assessment, in vitro drug
release, and in vivo tape stripping test were evaluated on the emulgel of RuxoLip. Validating the
analysis method was performed by UV spectroscopy.
Results: Nanoliposomal preparation was successfully formulated with a good particle size
(218±2 nm), an EE of 67%, and a DL of 8%. The formulation was stable in a long-term condition.
SEM showed that liposomes had a regular spherical surface. Moreover, in vitro drug release and
the in vivo tape stripping test revealed good absorption and permeation, respectively.
Conclusion: The liposome dosage form is anticipated to be a perfect carrier for the topical drug
delivery system of ruxolitinib in autoimmune skin disorders.
