*5.1.3 Oral strip*

The oral strip, a thin film made of hydrophilic polymers that liquefy quickly on the tongue or in the buccal cavity, is one such relatively recent dosage form [49]. Oral medication delivery has progressed from basic conventional tablets/capsules to

modified-release tablets/capsules to oral disintegrating tablets to wafer to the newest creation of oral strips due to research and development. Essentially, an oral strip is a postage-stamp-sized ultra-thin strip containing an active agent or active medicinal component as well as additional excipients. The simplicity of administration and portability of oral strips have led to a greater acceptance of this dose form among both paediatric and geriatric patients [50].

However, because the oral strip technology's derived devices were easily available in the marketplace in the type of breath-freshening strips, no additional determinations were required to re-instruct the general public on how to administer this dosage form. With the release and well-known usage of Listerine pocket strips, a novel unveiling in the mouthwash line, oral strip tools was already popular among the public in the early 2000s. This delivery mechanism can accommodate a wide range of compounds. Cough/cold cures (antitussives, expectorants), sore throat, erectile dysfunction medications, antihistaminics, antiasthmatics, gastrointestinal issues, nausea, pain, and CNS stimulants are just a few examples (e.g. antiparkinson disease). Caffeine strips, snoring aids, multivitamins, and sleeping aids are some of the other applications [51].
