However, the clinically used dosage has poor tissue permeability and injection safety. By contrast, lipid nanoparticles (LNPs) have the advantage of high affinity for the skin.Materials and methods: This article describes the preparation of TAA-LNPs using poly(lactic-co-glycolic acid) as a carrier material, which have good biocompatibility and biodegradability. Based on a systematic investigation of its physicochemical properties, a rabbit ear HSs model was established to evaluate the percutaneous permeability of TAA-LNPs in scar tissue in vitro as well as to assess its curative effect and skin irritation. Results: The results showed that the TAA-LNPs formed uniform and round particles under fluoroscopy and had a complex structure in which a nanoparticle core was surrounded by multiple vesicles. The particles were 232.2±8.2 nm in size, and the complimentary potential was -42.16 mV. The encapsulation efficiency was 85.24%, which is greater than that of other common liposomes and nanoparticles. A test of in vitro scar tissue permeability showed that penetration into scar tissue was twofold and 40-fold higher for TAA-LNPs than for common liposome and commercial suspensions, respectively. The concentration of the absorbed drug effectively inhibited fibroblast proliferation, achieved a therapeutic effect in HSs, and did not stimulate intact or damaged skin. Conclusion: The preparation of TAA into LNPs for transdermal administration can enhance transdermal permeation performance and the safety of this drug, which is beneficial for the treatment of HSs.
