Bottom Line: MDFs with PVP K30 and SLS gave superior dissolution properties when compared to MDFs without PVP K30 and SLS.The dissolution properties of MDFs with PVP K30 were superior when compared to MDFs with SLS.In the case of F3 containing 7.5% of HPMC E3 and 0.04% of PVP K30, complete and faster release was observed within 60 sec when compared to other formulations.

ABSTRACT
The present investigation was undertaken with an objective of formulating mouth dissolving films (MDFs) of Amlodipine Besylate (AMLO) to enhance convenience and compliance of the elderly and pediatric patients for better therapeutic efficacy. Film formers like hydroxy propyl methyl cellulose (HPMC) and methyl cellulose (MC) along with film modifiers like poly vinyl pyrrolidone K30 (PVP K30), and sodium lauryl sulphate (SLS) as solubilizing agents were evaluated. The prepared MDFs were evaluated for in vitro dissolution characteristics, in vitro disintegration time, and their physicomechanical properties. All the prepared MDFs showed good mechanical properties like tensile strength, folding endurance, and % elongation. MDFs were evaluated by means of FTIR, SEM, and X-RD studies. MDFs with 7.5% (w/w) of HPMC E3 gave better dissolution properties when compared to HPMC E5, HPMC E15, and MC. MDFs with PVP K30 and SLS gave superior dissolution properties when compared to MDFs without PVP K30 and SLS. The dissolution properties of MDFs with PVP K30 were superior when compared to MDFs with SLS. In the case of F3 containing 7.5% of HPMC E3 and 0.04% of PVP K30, complete and faster release was observed within 60 sec when compared to other formulations. Release kinetics data reveals diffusion is the release mechanism.

Mentions: Selected AMLO MDFs (F1, F2, and F3) were subjected to X-RD studies in order to investigate the crystallographic properties of AMLO in MDFs. AMLO showed characteristic peaks at 6.5°, 20.6°, 23.6°, and 24.93° 2θ. The X-ray diffractograms of the AMLO MDFs showed weak or no signals when compared to the characteristic peaks of pure AMLO. This may be due to molecular dispersion of AMLO within the MDFs. Overall, together with SEM data the X-RD results clearly indicate that the AMLO was not in crystalline state in MDFs. The X-ray diffractograms are shown in Figure 3.
