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,...

The possibility to compress ordinary paper into tablets was systematically investigated in this study. Results proved that tablets can be made from paper, independent of the type of paper used. The tablets appear shiny and with a smooth surface. The pharmaceutical quality was acceptable, i.e. all tablets fulfilled the requirements for tablets according to the European Pharmacopeia. Drug-loaded tablets were produced by compression of drug-loaded paper. Drug loading did not alter the...

Cell-free permeation systems are gaining interest in drug discovery and development as tools to obtain a reliable prediction of passive intestinal absorption without the disadvantages associated with cell- or tissue-based permeability profiling. Depending on the composition of the barrier, cell-free permeation systems are classified into two classes including (i) biomimetic barriers which are constructed from (phospho)lipids and (ii) non-biomimetic barriers containing dialysis membranes. This...

Extended drug delivery offers numerous benefits compared to immediate release dosage form. Membrane coating of immediate release dosage form is an effective means of producing an extended drug delivery system. Polymers when coated alone, have limited ability to form the rate controlling membrane with good mechanical properties.

Selective laser sintering (SLS) 3-dimensional printing is currently used for industrial manufacturing of plastic, metallic and ceramic objects. To date there are no reports on the use of SLS to fabricate oral drug loaded products, hence, the aim of this work was to explore the suitability of SLS printing for manufacturing medicines.

A frovatriptan ODT formulation was successfully developed by Quality by Design. It represents an effective alternative to conventional tablets, allowing easier oral administration (also to paediatric and geriatric people) and very faster drug dissolution, enhancing patient compliance and facilitating an earlier treatment of migraine attacks.
