| خلاصه مقاله | Metformin, an oral antihyperglycemic drug, is typically the first-line oral treatment for type II diabetes [1]. Conventional oral dose forms of metformin (regular and extended-release formulations) result in substantial changes in plasma drug concentration and offer no control over drug administration [2]. Metformin's key drawbacks are its relatively low bioavailability (about 50–60 percent) and short half-life [3]. This study aimed to develop a buccoadhesive film containing metformin nanoparticles (NPs) for increased medication bioavailability. Metformin nanoparticles were produced via nanoprecipitation and subsequently cast into an HPMC-Chi mix film. The essential formulation variables were evaluated using a three-factor Box–Behnken design with three stages. The penetration of the medication was also studied using buccal mucosa from sheep. The results confirmed the creation of spherical nanoparticles with an average size of 177.8 6.42 nm and entrapment effectiveness of 78.03 0.1%. The nanofilms possessed satisfactory physicochemical properties and drug concentration. Additionally, the ex vivo study revealed that the buccal mucosa has a high drug permeability. The optimal conditions for nanofilms were anticipated to be 700 mg of hydroxypropyl methylcellulose, 50 mg of glycerol, and 0.15 percent by weight of chitosan. The nanofilm demonstrated a high drug penetration within 6 hours and provided an exceptional opportunity for buccal medication administration. |
