The pharmaceutical sector is looking for new ways to deliver drugs, and one such way is through thin films. It has been said that thin films offer an alternative to traditional dosage forms. They offer rapid, local, or systemic effects and are a very flexible platform. Furthermore, patients with dysphagia, elderly, paediatrics, or bedridden patients, as well as those who have difficulty accessing water, can easily utilize these systems on their own. There are several ways to administer these drug delivery systems, including transdermally, ocularly, buccally, sublingually, and orally.

One of the most creative and patient-focused novel drug delivery systems is Orodispersible Thin Films (OTF). Numerous pharmaceutical companies and academic experts worldwide are currently investigating the potential of these films for delivering drugs derived from both synthetic and natural sources. The beauty of this special drug delivery method is that, as we can see from the subjects' consumption of conventional dosage forms (tablets, capsules), they don't require water to be consumed. Furthermore, these delivery methods do a great job of encouraging patient compliance in general, especially in the case of both older and pediatric patients.

This review shows a detailed review of oral thin film its applications and method of preparation; mainly focus of this research is thin film introduction to researchers and last 10 y of research on thin film with drugs and polymers used in research.
