Development of Mucoadhesive Film-Forming Systems Containing Black Ginger Extract for Aphthous Ulcers
Film-forming systems (FFSs) were developed by using Eudragit® E100 as a film former. Kaempferia parviflora (black ginger) extract was used as an anti-inflammatory agent for aphthous ulcers. The FFS could rapidly form a thin film in only 5 s when it was applied to a wet surface e.g. an aphthous…

Big family of nano- and microscale drug delivery systems ranging from inorganic materials to…
Traditional drug administration routs suffer from low selective distribution, poor solubility, fast elimination and damaging adjacent healthy tissues (especially in cancer therapy). Thus, drug delivery systems (DDSs) which could deliver drug to target site have broadly been investigated to upsurge…

Improved anticancer activity of betulinic acid on breast cancer through a grafted copolymer-based…
Betulinic acid (3β-Hydroxy-20(29)-lupaene-28-oic acid, BA) has excellent anti-cancer activity but poor solubility and low bioavailability. To improve the antitumor activity of BA, a polyvinyl caprolactam–polyvinyl acetate–polyethylene glycol (PVCL–PVA–PEG) graft copolymer (Soluplus) encapsulated BA…
