Development of Fast Dissolving Oral Films Containing Vitamin B6 for Nausea and Vomiting of Pregnancy (NVP)
The aim of this study was to formulate and evaluate the oral fast-dissolving film of Vitamin B6 for the effective management of motion sickness and vomiting during pregnancy. Fast-dissolving films were prepared by the solvent-casting method using different polymers, HPMC-15 and Pullulan, along with Propylene glycol as a plasticizer. The Fourier-transform infrared study for the drug-polymer interaction was carried out. Evaluation of physical parameters such as physical appearance, surface texture, uniformity of weight, uniformity of strip thickness, surface pH, folding endurance, uniformity of drug content and percentage of moisture absorption were performed. Kinetic data analysis for the release study and the stability study were also performed. Results of uniformity of weight, thickness, folding endurance, surface pH, percentage drug content, tensile strength and percentage elongation of all the films were found to be satisfactory. The Fourier-transform infrared study indicated that there was no interaction between the drug and the polymers. The in-vitro drug release study showed that a better rate of drug release was achieved by formulations F4 and F8 compared with other formulations. The stability study did not show any significant difference in the external appearance, the drug content and the in-vitro drug release. In conclusion present study suggested that fast dissolving films has a better ability to cross the sublingual barrier at a faster rate, and hence the delivery system was found to be promising as it has the potential of overcoming the drawbacks associated with tablet formulations available in the market presently.
