Special Issue Information

Dear Colleagues,

In the past several years, we have witnessed a remarkable interest in sublingual and buccal drug delivery systems. The sublingual route is very attractive for low-dose therapeutic agents and drugs for emergency use such as pain reduction, acute angina pectoris, opioid addiction, and anaphylactic shock. The route has also been favorable for pediatric formulations since young children are unable to swallow tablets or capsules. The physiology of sublingual absorption provides an alternative to oral absorption for low-dose small molecules, peptides, or even proteins that are prone to degradation in the gastric intestinal tract. Potentially, this route can also be feasible for vaccines and other peptides and proteins delivered at very low doses with the help of solid lipid nano particles or other penetration enhancers. 

The purpose of this Special Issue of Pharmaceutics is to draw attention to the importance of sublingual and buccal delivery systems and to provide scientists with a platform to publish their novel research work in this area. 

This Special Issue seeks novel topics pertaining to “Advanced Strategies for Sublingual and Buccal Drug Delivery”. Original research as well as reviews will be considered for publication.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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 100 words) can be sent to the Editorial Office for announcement on this website.

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.

The permeability of the oral or nasal mucosa is higher than that of the skin. Mucosa permeability depends mainly on the thickness and keratinization degree of the tissues. Their permeability barrier is conditioned by the presence of certain lipids. This work has the main aim of reinforcing the barrier effect of oral mucosa with a series of formulations to reduce permeation. Transmembrane water loss of different formulations was evaluated, and three of them were selected to be tested on the sublingual mucosa permeation of drugs. Caffeine, ibuprofen, dexamethasone, and ivermectin were applied on porcine skin, mucosa, and modified mucosa in order to compare the effectiveness of the formulations. A similar permeation profile was obtained in the different membranes: caffeine > ibuprofen~dexamethasone > ivermectin. The most efficient formulation was a liposomal formulation composed of lipids that are present in the skin stratum corneum. Impermeability provided by this formulation was notable mainly for the low-molecular-weight compounds, decreasing their permeability coefficient by between 40 and 80%. The reinforcement of the barrier function of mucosa provides a reduction or prevention of the permeation of different actives, which could be extrapolated to toxic compounds such as viruses, contaminants, toxins, etc. Full article
