Enteric polymers have been found with absorption promotion effect on nanoparticles. To study the role of enteric polymers played in the process of oral nanoparticle delivery, Eudragit L100-55 (EU) and sodium alginate (SA) were selected as model enteric polymers and larotaxel (LTX) as model drug. Suspensions composed of LTX-loaded nanoparticles, HPMC and different enteric polymers (EU and SA) were prepared (NP@EU, NP@SA). And aspects like precipitate morphology upon contact with acid,...

Numerous studies have been focused on hydrophobic compounds encapsulation as oils. In fact, oils can provide numerous health benefits as synergic ingredient combined with other hydrophobic active ingredients. However, stable microparticles for pharmaceutical purposes are difficult to achieve when commonly techniques are used. In this work, sunflower oil was encapsulated in calcium-alginate capsules by prilling technique in co-axial configuration.

The object of this study is to prepare and evaluate tablets with predesigned internal scaffold structure using 3D printing to achieve sustained drug release. Model drug (ibuprofen) and sustained release material (ethyl cellulose), together with other excipients, were firstly mixed and extruded into filaments by hot melt extrusion. Then these obtained filaments were printed into tablets by fused deposition modeling.

Mucoadhesive formulations are well known for the delivery of drugs via the mucosal membrane of oral (sub- lingual, buccal and gingival), rectum, nose, eyes, and vagi- na. Among the various drug delivery approaches, the buc- cal mucosa delivery system o ers several bene ts like easy accessibility, patient compliance, a relatively large surface area of absorption for drug molecules, reduced gastric ir- ritation and simple delivery devices.
