FORMULATION AND EVALUATION OF ORAL DISINTEGRATING FILM OF ATENOLOL
Objective: The main objective of the study was to formulate the oral disintegrating films loaded with atenolol by solvent-casting method and to carry out its evaluation studies.
Methods: The films were prepared using the film-forming hydrophilic polymer like hydroxypropyl methylcellulose (E-5) and super disintegrant like pectin in various proportions.The formulated oral films were characterized for Fourier transform infrared (FTIR) and morphological evaluations. Various physicochemical parameters such as weight variation, folding endurance, surface pH, in vitro disintegration, and in vitro dissolution studies were carried out.
Results: FTIR studies revealed that there was no drug-polymer interaction. The morphological evaluation of films showed that all the films were homogenous and transparent. The folding endurance test ensured that the films had sufficient brittleness and by weight variation test, it was inferred that all the films were within the deviation. The surface pH study showed the pH of the films was around neutral pH. The drug was well distributed in all the films. The films disintegrated within 120 s and the fastest being disintegrated in 30 s. Based on all the evaluation parameters, F6 had shown optimal performance and remarkable increase in drug release of 94.38% in 2 min.
Conclusion: Thus, formulated oral disintegrating films can be termed as an alternative approach to deliver atenolol.
