Abstract
BACKGROUND: Rosuvastatin Calcium and Ezetimibe are used to control cholesterol level while Perindopril Erbumine is used to treat hypertension. Hepatic metabolism reduces the therapeutic effect of these drugs. OBJECTIVE: Instant release buccal films (IRBFs) could possibly be a solution to this issue. The objective of the study was to formulate IRBFs of Rosuvastatin Calcium, Perindopril Erbumine and Ezetimibe using solvent casting technique. METHODS: Polymers used to prepare IRBFs included hydroxypropyl methylcellulose (HPMC E5), PEG 400 (as plasticizer) and Tween 80 (as surfactant). Solvent casting technique was used to fabricate the films, followed by their in-vitro analysis including high performance liquid chromatography (HPLC), X-ray diffraction (XRD), fourier transform infrared evaluation (FTIR), In-vitro dissolution, In-vitro disintegration, stability tests, scanning electron microscopy (SEM), folding fortitude, thickness evaluation, surface pH, tensile strength, weight variation and percentage moisture content. RESULTS: Optical microscopy as well as SEM analysis displayed that the surfaces of IRBFs were smooth with uniform mixing of ingredients. IRBFs disintegrated within 15 seconds while on dissolution they exhibited instant drug release i.e. 100% release in 2 minutes. CONCLUSIONS: The results show promising potential of IRBFs in drug delivery.
