Oral Dispersible Films from Product Development to End-User Acceptability: A Review

Orodispersible films (ODFs) have served as an emerging platform for the delivery of drugs in a convenient way. They have numerous advantages, the significant one is simplicity of administration for special populations such as pediatric and geriatric as well as patients with swallowing difficulty. Besides, the advantages include accurate dosing and fast action. The ODFs are efficiently designed with detailed knowledge of drug and polymers as well as a suitable selection of method. Many conventional and advance formulation strategies have been used for the development of ODFs. The biopharmaceutical concerns of active pharmaceutical ingredients (APIs) are given in this review in light of the fact that ODFs can be utilized to increase the bioavailability of APIs. The basic critical issues such as good mechanical properties, water solubility of the API and taste masking are very important to be considered during the development of ODFs. The knowledge of critical quality concerns of ODFs will be helpful in the future development of ODF. As ODFs remain in the mouth until complete degradation, taste, texture and mouth-feel are the qualities that in all respects liable for acceptability of the patient. An assortment of packaging choices is also accessible for ODFs. This review focuses on the different critical concerns of ODF related to composition, bio-pharmaceutical, manufacturing, quality tests, packaging and acceptability. Additionally, potential barriers in the ODFs development are discussed in details. Therefore, this review is an informative bundle of ODFs concerns from the product development stage to the end-user acceptability.
