The electrospun nanofiber-based orally dissolving webs are promising candidates for rapid drug release, which is due to the high surface area to volume ratio of the fibers and the high amorphization efficacy of the fiber formation process. Although latter is responsible for the physical and/or chemical instability of these systems. The primary aim of the present study was to elucidate how the addition of polysorbate 80 (PS80) and hydroxypropyl-β-cyclodextrin (HP-β-CD) influenced the...

Fused deposition modeling 3D printing (3DP) has a potential to change how we envision manufacturing in the pharmaceutical industry. A more common utilization for FDM is to build upon existing hot melt extrusion technology where the drug is dispersed in the polymer matrix. However, reliable manufacturing of drug-containing FDM filaments remains a challenge along with the limitation of active ingredients which can sustain the processing risks involved in the HME process. To circumvent this...

Despite the enormous potential of nanomedicine, the search for materials from renewable resources that balance bio-medical requirements and engineering aspects is still challenging. This study proposes an easy method to make nanoparticles composed of oxidized starch and chitosan, both isolated from natural biopolymers. The careful adjustment of C/N ratio, polymer concentration and molecular weight allowed for tuning of particle characteristics.

Solid oral dosage forms (SODF) are drug vehicles commonly prescribed by physicists in primary and secondary cares, as they are the most convenient for the patient and facilitate therapy management. Concerns regarding unintended adhesion of SODF during oro-esophageal transit remain, especially in multimorbid patients, bedridden patients and patients suffering from dysphagia.

Mucus is a highly hydrated viscoelastic gel present on various moist surfaces in our body including the eyes, nasal cavity, mouth, gastrointestinal, respiratory and reproductive tracts. It serves as a very efficient barrier that prevents harmful particles, viruses and bacteria from entering the human body.

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.

Spray drying is a well-established scale-up technique for the production of cocrystals. However, to the best of our knowledge, the effect of introducing a third component into the feed solution during the spray drying process has never been investigated.

Fast dissolving oral films (FDFs) provide an alternative approach to increase consumer acceptance by advantage of rapid dissolution and administration without water. Usually FDFs require taste-masking agents. However, inclusion of these excipients could make developing the formulation a challenging task. Hence, this work employed fused-deposition modelling three-dimensional (FDM 3D) printing to produce single-layered (SLFDFs), or multilayered (MLFDFs) films, with taste-masking layers being...

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.
