Abstract
The primary objective of the present research work was to develop nanoparticles incorporating (nanoparticulate) fast dissolving (orodispersible) film evincing enhanced solubility and bioavailability of nitrendipine (NIT). An antisolvent sonoprecipitation method was employed to produce the NIT nanosuspension (NS), which was optimized using the 32 optimal response surface design and then the optimized one was evaluated for various parameters (Gandhi et al., AAPS PharmSciTech 22 (1):1–15, 2021). The NIT nanoparticulate orodispersible film (N-ODF) was prepared utilizing the nanosuspension by the solvent casting method using the Vijay film-forming instrument. The N-ODF was optimized by the 23 full factorial design and was evaluated for several parameters. The optimized NS depicted a particle size of 505.74 ± 15.48 nm with a polydispersity index (PDI) of 0.083 ± 0.006 (Fig. 1b). The NIT nanoparticles showed a striking increment in saturation solubility (26.14 times), when compared with plain NIT (2). The developed NIT N-ODF exhibited thickness (0.148 ± 0.008 mm), folding endurance (280.33 ± 5.51 times), surface pH (6.86 ± 0.05), tensile strength (8.25 ± 0.13 kg/cm2), % elongation (63.5 ± 1.97%), and disintegration time (24.60 ± 1.31 s) to be within the standard intended limit. The in vitro dissolution study unveiled 100.28 ± 2.64% and 100.68 ± 2.50% of NIT release from lyophilized nanocrystals (in 8 min) and N-ODF (in 3.5 min), respectively, whereas the conventional NIT tablet took 30 min to release 99.94 ± 1.57% of NIT (Gandhi et al., AAPS PharmSciTech 22 (1):1–15, 2021). The in vivo pharmacokinetic study in rabbits inferred the achievement of significantly (p < 0.05) higher bioavailability of NIT on release from N-ODF in comparison to the conventional NIT tablet. Thus, the generation of N-ODF can be considered as a propitious move toward improving the efficacy of NIT to treat hypertension and angina pectoris.Keywords
