Development of Oral Fast-Disintegrating Levothyroxine Films for Management of Hypothyroidism in Pediatrics
Zhang, He; Han, Mei-Gui; Wang, Yun; Zhang, Jie; Han, Zi-Ming & Li, Shu-Jun
Abstract
Purpose: To develop fast disintegrating films of levothyroxine (LVX) using hydrophilic hydroxypropyl
methylcellulose (HPMC), croscarmellose sodium (CCS) as superdisintegrant, and propylene glycol (PG)
as a plasticizer.
Methods: Fast-disintegrating films were formulated by solvent casting evaporation method using 3-
factor, 2-level full factorial design. The films were evaluated for disintegration time, in vitro drug release,
physical appearance, thickness, weight variation, folding endurance, drug content uniformity, The effect
of concentration of dependent variables (HPMC, CCS and PG) on disintegration time and in vitro drug
release was studied.
Results: Suitable fast-disintegrating films were obtained using HPMC, CCS and PG. The minimum
disintegration time (DT) was 15 s and maximum drug release (DR) in 1 h was 97.56 %. All
independent variables selected for the study were statistically significant (p < 0.5). Increase in the
concentrations of independent variables increased DR and DT.
Conclusion: The findings of this study indicate that the developed fast-disintegrating film is suitable for
levothyroxine in the management of hypothyroidism in pediatrics.\
