Oro dispersible Films (ODFs): A patient-centric approach in drug delivery

Oro dispersible films (ODFs) are a novel oral drug delivery system designed to dissolve quickly in the oral cavity, typically within 30 seconds, without the need for water or swallowing. These ultra-thin strips, ranging from 10 to 100 microns in thickness, are particularly suitable for populations with special needs, such as pediatric and geriatric patients, and individuals suffering from conditions like dysphagia, Parkinson's disease, or oral cancer. ODFs offer several advantages, including improved patient convenience and compliance, rapid onset of therapeutic effect, and the ability to bypass first-pass metabolism. The formulation components of ODFs include film-forming polymers, plasticizers, active pharmaceutical ingredients, sweeteners, flavors, and surfactants. Various manufacturing techniques, such as solvent casting, hot-melt extrusion, and electrospinning, can be used to prepare ODFs, each with its own advantages and limitations. Despite the benefits, ODFs also have some challenges, including moisture sensitivity, limited drug-loading capacity, and potential issues with content uniformity and manufacturing. Nevertheless, ODFs have shown promise in various therapeutic applications, including the delivery of antiasthma tics, antiemetics, antipsychotics, and antihistamines. With ongoing advancements in polymer combinations and manufacturing technologies, ODFs are expected to play an increasingly important role in the development of personalized and effective drug delivery systems.
