Buccal drug delivery has become the most important route of administration of drug due to unwilling of oral administration of solid preparations by both pediatric and geriatric patients. This has led to development of alternate route of administration like film drug delivery system. Fast dissolving drug delivery systems were developed in 1970s as an alternative to syrups, capsules and tablets for pediatric and geriatric patients. They have been accepted easily as new drug delivery system because of easy administration, rapid drug absorption, better patient compliance and good bioavailability.
