Then, IBU was incorporated into B-BMSF@PEI at the drug:carrier weight ratio of 1:1. The structural features of IBU before and after drug loading were systemically characterized. IBU and B-BMSF@PEI were then subject to in vitro drug release study and wettability analysis. Finally, in vivo pharmacokinetics and anti-inflammatory pharmacodynamics studies were carried out to evaluate the efficacy of B-BMSF@PEI on improving the oral adsorption of IBU.Results: The results demonstrated that B-BMSF@PEI was a meso–meso porous silica material with foam appearance. It consisted of uniform spherical cells (40 nm) with interconnected pore networks. IBU can be successfully loaded into B-BMSF@PEI with high efficiency (as high as 39.53%), and crystal IBU was effectively converted to an amorphous state during this process. Benefiting from the great architectures of B-BMSF@PEI, IBU/B-BMSF@PEI performed good wetting property and significantly improved the dissolution rate in both simulated gastric fluid (SGF) and simulated intestinal fluid (SIF). Notably, IBU exhibited very satisfactory relative bioavailability (681.4%) and anti-inflammatory effects (the inhibition rates were between the ranges of 113.5% to 1504.3%).Conclusion: B-BMSF@PEI with bimodal mesoporous system and interconnected nanopores was obtained owing to the dynamic self-assembly functions of PEIs. It had superiority in drug loading and could improve the oral adsorption of ibuprofen to a satisfactory level.Keywords: biomimetic synthesis, MSF, bimodal mesostructured, bioavailability, ibuprofenXin WWang YGuo XGou KLi JLi SZhao LLi HDove Medical Pressarticlebiomimetic synthesismsfbimodal mesostructuredbioavailabilityibuprofenMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 15, Pp 7451-7468 (2020) |
