title: Fast disintegrating films containing anastrozole as a dosage form for dysphagia patients.
abstract: The objective of the present research was to ensure safety during oral administration of medications to dysphagia patients, by preparing fast disintegrating films (FDF) containing anastrozole (ANS) which disintegrate rapidly when placed on the tongue. Films were prepared by solvent-casting method using various polymers such as hydroxyl propyl methyl cellulose (HPMC E5 LV), hydroxy propyl cellulose (HPC), poly vinyl alcohol (PVA) and sodium alginate (Na Alginate). Among the formulations examined, film prepared using HPMC E5 LV (F1) exhibited shorter disintegration time (15 sec) with satisfactory mechanical properties. Fourier transformer infrared (FTIR) & differential scanning calorimetry (DSC) analysis revealed no chemical incompatibility between drug and excipients used in the formulation. Surface morphology revealed even distribution of ANS in the film. Dissolution of drug from F1 formulation was rapid with more than 90% drug release in 240 sec. Pharmacokinetic parameters showed no statistical difference between F1 (test) and drug solution (control) indicating comparable plasma level-time profiles. The film showed an excellent stability for 24 weeks when stored at refrigerated temperature (2-8°C). These findings suggest that the fast disintegrating film as a promising candidate for delivery of ANS in dysphagic patients.
