Empagliflozin containing chitosan-alginate nanoparticles in orodispersible film: preparation, characterization, pharmacokinetic evaluation and its anticancer activity.

Objective: The main objective of this study was to develop the orodispersity film containing chitosan-alginate nanoparticles to improve dissolution profile, therapeutic effect with improved bioavailability of empagliflozin through oral route noninvasively for further cytotoxicity study.

Methods: The nanoparticles were developed through two-step mechanisms ionotropic pre-gelation and polyelectrolyte complexation methods. The prepared nanoparticles were added to a polymer matrix containing hypromellose, polyvinyl alcohol, and maltodextrin and cast to rapidly dissolving thin film by solvent casting method.

Development of Biocompatible Nanoparticles of Tizanidine Hydrochloride in Orodispersible Films: Characterization, Permeation, and Cytotoxic Study on Carcinoma Cells.

Background: The main limitations of the therapeutic effectiveness of tizanidine hydrochloride (TNZ) are its low bioavailability due to its tendency to undergo first-pass metabolism and short biological half-life. These factors make it an ideal candidate for formulating orally disintegrating films.

Objective: The present study was aimed to prepare nanoparticles of tizanidine hydrochloride using biodegradable polymers and loading them on orodispersible films to obtain a sustained release dissolution profile with improved permeability and further study the cytotoxicity on A549 lung carcinoma cells, MCF7 breast cancer cells, and HOP 92 non-small lung adenocarcinoma cells.
