Summary of "Overview and Future Potential of Fast Dissolving Buccal Films as Drug Delivery System for Vaccines."

Vaccination is considered one of the most successful public health interventions of the modern era. Vaccines are categorized based on the antigen used, delivery system and the route of administration. Traditional vaccines are produced from the dead, attenuated or inactivated pathogens that cause disease. However, newly developed vaccines are DNA based, liposome based, and virus like particle (VLP) based which are more effective and specific to some malignant diseases. The delivery system of vaccines has been advanced along with time as well. New delivery systems such as nanoparticles, liposomes, or cells (for DNA) has been proven to develop a more efficient vaccine. Most vaccines are administered via intramuscular (IM), subcutaneous (SQ) or oral (PO) route. However, these routes of administration have limitations and side effects. An alternative route could be oral cavity administration such as buccal or sublingual administration using film dosage form as delivery vehicle. In this article, we thoroughly reviewed the possibility of developing a quickly soluble film-based delivery system for vaccine administration. We reviewed the different types of new vaccines and vaccine formulations such as VLP based, liposome, bilosome, particulate, and summarized their suitability for use in a film dosage form. Quickly soluble film dosage form is the most optimized form of buccal administration. A film dosage form applied in the buccal cavity has several advantages: they can avoid first pass effect, they are easy to administer and prepare, and they are more cost effective. Since there is no first pass effect, only a small quantity of the vaccine is needed. Vaccines in their original form or in a nano or microparticulate form can be used in a film. The film can also be developed in multilayers to protect the vaccine from degradation by saliva or swallowing. Films are easy to prepare, administer, and can be used for systemic and local action. In addition, most of the current vaccines use mostly the parenteral route of administration, which has some major drawbacks such as poor induction of mucosal immunity, less patient compliant, less potent, high cost and cumbersome production process. Sublingual and buccal vaccine delivery can be good alternatives as they are easier to prepare and safer than parenteral administration routes. The buccal and sublingual administration have the advantage to produce both systemic and mucosal immunity.
