Four natural sweeteners (sucrose, xylitol, fructose, and isomalt) were selected to examine the influence of their qualities and amounts on the characteristics of orodispersible films. Sodium carboxymethylcellulose (2% w/w) was utilized as the film-forming polymer and 1% w/w glycerol as a plasticizer. Films were produced through the solvent casting method, rendering them suitable for convenient application in community or hospital pharmacy settings. The physicochemical and optical properties of the films were analyzed, and Fourier-transform infrared analysis was carried out. All films exhibited acceptable disintegration time, uniformity of mass, thickness, and optical characteristics, with significant dependence (p<0.05) on both sweetener type and quantity. Disintegration time varied based on the employed method, as well as the characteristics and amount of sweetener. Additionally, all films maintained pH values within the oral cavity range, suggesting no potential irritancy upon administration. Fourier-transform infrared analysis confirmed the formation of the film and demonstrated compatibility between its components.
