Fluconazole Mucoadhesive Buccal Films: In Vitro/In Vivo Performance
Fluconazole mucoadhesive buccal films were prepared using film forming polymers namely; hydroxypropyl methyl cellulose (HPMC), hydroxyethyl cellulose (HEC), chitosan, Eudragit and sodium alginate (SALG) either alone or in combination with bioadhesive polymers. The bioadhesive polymers studied were sodium carboxymethyl cellulose (SCMC), Carbopol 974P, and polycarbophil (AA-A). The prepared films were characterized by means of film thickness, surface pH, swelling capacity, in vitro adhesion, in vivo residence time, in vitro drug release and in vivo drug release to determine the amount of drug release from selected film formulae using microbiological assay and HPLC. Optimum release behavior, convenient bioadhesion, acceptable elasticity were exhibited by film containing 2% HPMC and 1% SCMC (fresh or stored for 6 months). Determination of the amount of drug released in saliva after application of the selected fluconazole films confirmed the ability of the film to deliver the drug over a period of approximately 300 minutes and to reduce side effects and possibility of drug interaction encountered during systemic therapy of fluconazole, which would be beneficial in the case of oral candidiasis.

- The aim of Current Drug Delivery is to publish peer-reviewed articles, short communications, short and in-depth reviews in the rapidly developing field of drug delivery. Modern drug research aims to build in delivery properties of a drug at the design phase, however in many cases this ideal cannot be met and the development of delivery systems becomes as important as the development as the drugs themselves.
The journal aims to cover the latest outstanding developments in drug and vaccine delivery employing physical, physico-chemical and chemical methods. The drugs include a wide range of bioactive compounds from simple pharmaceuticals to peptides, proteins, nucleotides, nucleosides and sugars. The journal will also report progress in the fields of transport routes and mechanisms including efflux proteins and multi-drug resistance.
The journal is essential for all pharmaceutical scientists involved in drug design, development and delivery.
