Novel Formulation Strategies for Enhancing Dissolution and/or Oral Bioavailability

Dear Colleagues,

Poor oral bioavailability has become a major challenge in drug development due to both poor water-solubility and poor permeability across intestinal biomembranes. Despite significant efforts to optimize drug leads, about 40% of currently marketed drugs and 70% of drug candidates are poorly water-soluble. It is worse that a fraction of poorly water-soluble entities is poorly permeable as well. To enhance oral bioavailability, it is a prerequisite to improve the dissolution rate in the gastrointestinal tract. For BCS II (poor solubility, high permeability) drugs, enhancement of dissolution is workable, whereas for BCS IV (poor solubility, poor permeability), enhancement of both dissolution and permeability is highly demanded. Various formulation strategies have been employed in the past to enhance the dissolution and subsequent oral absorption of poorly water-soluble drugs, such as solid dispersion, inclusion complexation, nanosizing, co-crystallization and lipid-based delivery systems. Enhancing dissolution and/or oral bioavailability is an enduring theme.

This Special Issue serves as a forum to bring together prominent scientists from all around the world and presents their work together to draw attention from a grand audience. We invite review or original articles on all aspects of “Novel Formulation Strategies for Enhancing Dissolution and/or Oral Bioavailability”.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pharmaceutics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
