Abstract:
Objective: To prepare piroxicam nanostructured lipid carrier and investigate its transdermal absorption behavior in vitro. Methods:Piroxicam nanostructured lipid carrier was prepared by a melt-emulsion ultrasonication and low temperature-solidifica-tion method. The physicochemical properties such as appearance, morphology, particle size distribution, PdI and zeta potential of pi-roxicam nanostructured lipid carrier were evaluated. The transdermal absorption in vitro was investigated using Franz diffusion cells. Results:Piroxicam nanostructured lipid carrier was clear and transparent with small spherical shape as seen under a transmission elec-tron microscope. The particle size distribution, PdI and zeta potential was (106. 4 ± 31. 6) nm, (0. 217 ± 0. 07) and ( -31. 6 ± 2. 5) mV, respectively. Piroxicam nanostructured lipid carrier had higher cumulative transdermal amount in 12 h than piroxicam solution. Conclusion:The nanostructured lipid carrier can remarkably improve piroxicam permeation into skin, which provides reference for the new dosage form for the topical use of piroxicam.
