Disturbed sleep can cause to m health problems such as cognitive impairment, depressed mood, and negative effects on cardiovascular, endocrine, and immune function. This study formulates and optimizes Eszopiclone trilaminate fast dissolving film. Prepared Eszopiclone trilaminate fast dissolving film (Eszopiclone TFDF) was characterized by disintegration time, drug release, tensile strength (TS), percentage elongation (EB%), folding endurance, taste masking test, and in vitro dissolution test. The selected formulas were F2 (0.5% xanthan gum, 10% propylene glycol), F4 (3% sodium alginate, 10% propylene glycol) and F6 (1.5% pullulan, 10% propylene glycol) were subjected to in vivo study compared to conventional Lunesta® tablet. The results indicated that disintegration time was in the range of 940 m. Drug release was found to be in the field of 78.51%-99.99%, while TS values and EB% differed from 11.12 to 25.74 (MPa) and 25.38%-36.43%, respectively. The folding endurance went between 200 and 300 times. All formulas exhibited acceptable uniformity content, surface pH, film thickness, and a good taste feeling. F4 had the highest Cmax (39.741 ± 6.785-μg/l) and lower Tmax (1.063 hr) among other formulas and conventional tablets. Therefore, FDFs' technology could increase the therapeutic effect of Eszopiclone.
