Abstract:
Objective: To prepare dexketoprofen trometamol hydrogel patches, optimize the formula and evaluate in vitro transdermal properties.Methods: Dexketoprofen trometamol hydrogel patches were prepared with NP-800 as the hydrogel patch carrier, aluminum hydrochloride as the crosslinking agent, EDTA as the crosslinking modifier and glycerol as the moisturizing agent.The formula was screened by orthogonal design with the initial viscosity, holding force, peel strength and 12 h cumulative transdermal quantity as the evaluation indices to screen out the best formula.The transdermal absorption test was carried out with an improved Franz diffusion cells to compare the enhancement of Aznoe, oleic acid and menthanol on dexketoprofen trometamol hydrogel patches.Results: The best formula was as follows: the mass percentage of NP-800, glycerol, glycerol and EDTA was 5%, 0.3% , 25% and 0.15% , respectively.The transdermal enhancers had transdermal enhancement on dexketoprofen trometamol, and among them, 3% Azone had the most significant enhancement with the enhancing rate of 3.26.Conclusion: The preparation and formula of dextroxyprofen trometamol hydrogel patches are stable, reasonable and feasible.
