Mucoadhesive nanoparticles-based oral drug delivery systems enhance ameliorative effects of low molecular weight heparin on experimental colitis

Low molecular weight heparin (LMWH) is reported to have therapeutic action on ulcerative colitis (UC). To facilitate its oral administration and improve the colon-targeting property, LMWH-loaded nanoparticles (TMC-NPs and SA-TMC-NPs) are prepared and evaluated by a series of studies, including their stabilities, drug release profiles, mucosal permeation, mucoadhesion, cytotoxicities, cellular uptake profiles, anticoagulant and anti-inflammatory...
