OBJECTIVE To prepare Xiongzhi shigao decoction soluble microneedles， characterize it and investigate its transdermal properties in vitro. METHODS Two-step centrifugal method was used to prepare Xiongzhi shigao decoction soluble microneedles. The formability and mechanical property of the microneedles were evaluated from aspects of stroma fluidity， microneedle formability， needle hardness， etc. The appearance， mechanical strength， dissolution performance， skin barrier recovery performance and drug loading of the prepared microneedles were characterized by using active components of the soluble microneedle （chlorogenic acid， ferulic acid， notopterol， imperatorin， ligustilide， isoimperatorin） as indicators. The in vitro transdermal performance was investigated by Franz diffusion cell. RESULTS The soluble microneedle tips of Xiongzhi shigao decoction prepared in this study were conical， evenly distributed and of the same thickness， with good mechanical properties； the tip of the needle could be almost completely dissolved after being penetrated into the skin of rats for 2 hours， and the skin barrier recovery performance was good； the drug loading of chlorogenic acid， ferulic acid， notopterol， imperatorin， ligustilide and isoimperatorin were （87.04±1.12）， （67.69±1.23）， （20.65±0.17）， （35.00±0.11）， （153.83±0.21） and （23.52±0.50） μg per patch respectively. The results of in vitro transdermal study showed that cumulative release rates of 6 active components in this microneedle after 72 hours were 36.94%， 56.72%， 19.36%， 57.98%， 11.06% and 35.19%， respectively. CONCLUSIONS Xiongzhi shigao decoction soluble microneedles are prepared successfully in this study and have good formability， mechanical properties and pliable backing， which can significantly promote the transdermal drug delivery.
