Mucoadhesive Drug Delivery Systems for Oral Chronic Inflammatory Mucosal Diseases. The Future is Already Present. A Systematic Review.

Background: Oral lichen planus (OLP) and recurrent aphthous stomatitis (RAS) are considered the most painful oral inflammatory diseases, with high global prevalence and significant impacts on patients' quality of life. In the last decades, researchers have been exploring mucoadhesive drug delivery systems (MDDS) to improve drugs safety and efficacy through optimized formulations for enhancing patients compliance while addressing the limitations of semisolid products.

Objective: To assess the clinical efficacy of different MDDS (e.

Efficacy and limitations of SARS-CoV-2 vaccines - A systematic review.

The emergence of the SARS-CoV-2 virus worldwide led to the call for the development of effective and safe vaccines to contain the spread and effects of COVID-19. Using information from 40 publications, including clinical trials and observational studies from 2019 to 2024, this review assesses the effectiveness, safety, and limitations of four major vaccines: Sinopharm (BBIBP-CorV), Moderna (mRNA-1273), Pfizer-BioNTech (BNT162b2), and CoronaVac. Pfizer-BioNTech and Moderna's mRNA vaccines proved to be more effective than others; Moderna's vaccines showed an efficacy of 94.

Characterization and Safety Assessment of a Novel Antioxidant Excipient from Sustainable Recovery of Grape Processing Waste Bentonite Designed to Develop a Thermosensitive Buccal Spray for Oral Cavity Wellness.

Background/objectives: Nowadays, sustainability efforts focus on extracting natural cosmeceutical ingredients, such as polyphenols, from agri-food waste, for example, black bentonite (BB). The aims of this work were to validate an antioxidant cosmetic ingredient obtained from the waste BB and embed it into an ad hoc designed oromucosal spray intended for oral cavity wellness.

Methods: Focusing on sustainability, the study tested PEG200, propylene glycol, and their mixtures as unconventional and green extraction solvents, aligned with a waste-to-market approach.

Plant-Derived Polyphenols to Prevent and Treat Oral Mucositis Induced by Chemo- and Radiotherapy in Head and Neck Cancers Management.

Oral Mucositis (OM) is the most common side effect due to chemotherapy and radiotherapy, which are the conventional treatment options for head and neck cancers. OM is a severe inflammatory condition characterized by multifactorial etiopathogenesis. It further negatively affects patients' quality of life by severe impairment of normal oral functions.
