Ondansetron-Loaded Orodispersible Films: A Fast-Dissolving Drug Delivery Strategy for Antiemetic Therapy
Abstract
Objective: The objective of the present study was to formulate and evaluate mouth dissolving films (MDFs) of Ondansetron Hydrochloride for the rapid management of nausea and vomiting, especially in pediatric and geriatric patients.Methods: MDFs were prepared by the solvent casting technique using Hydroxypropyl Methylcellulose (HPMC E15) as the film-forming polymer and Polyethylene Glycol 400 (PEG 400) as a plasticizer. Excipients like sucralose, citric acid, and peppermint flavor were incorporated for improved palatability and disintegration. Preformulation studies including UV spectroscopic identification, solubility analysis, melting point determination, and FTIR compatibility were carried out. The films were evaluated for various parameters such as thickness, folding endurance, weight variation, surface pH, disintegration time, drug content uniformity, and in vitro drug release. FTIR spectra were used to assess drug–excipient compatibility.
Results: The formulated films were transparent, smooth, and flexible with rapid disintegration time (20–22 seconds). Drug content was found to be uniform (~99%), and all physical parameters were within acceptable limits. In vitro dissolution studies revealed that over 85% of the drug was released within 5 minutes and ~97% within 10 minutes. FTIR studies confirmed no significant chemical interaction between drug and excipients.
Conclusion: The study demonstrated that mouth dissolving films of Ondansetron Hydrochloride can serve as a promising alternative to conventional oral dosage forms, offering rapid onset of action and ease of administration, particularly for patients with swallowing difficulties.
