Novel drug delivery systems have drawn more attention in recent years due to their potential to boost patient compliance, security, and safety and efficiency while also lengthening the life of a product patent life cycle. Several pharmaceutical companies have recently concentrated their research efforts on fast acting technologies. Most cutting edge oral solid dose form is quick dissolving oral thin films, which offers greater comfort and flexibility. It increases the effectiveness of active pharmaceutical ingredient by dissolving in the oral cavity in a matter of seconds after coming into contact utilizing fewer saliva than fast dispersing tablets, without chewing, and without the requirement for water for administration. For the formation of oral thin films, a variety of chemicals are used, such as polymers, active medicinal compounds, film stabilizing agents, plasticizers, surfactants, sweeteners, flavors, colors and salivary stimulate agents. Information in the current review relates to the formulation components, methods, and results of studies used to create fast dissolving oral thin films. Meanwhile, the market for fast dissolving oral thin films is well positioned for future expansion. The market for oral thin films appears to be poised for major growth.
