ARx Oral Thin Films (OTFs)

ARx, LLC custom develops and formulates drug-loaded oral thin film (OTF) polymer coatings designed to erode/dissolve at pre-determined rates when introduced to saliva for absorption in the gastrointestinal (GI) tract. OTFs are a beneficial means for administering treatments and improving compliance in pediatric, geriatric, veterinary and compromised patient populations.

Oral thin films can integrate most available forms of active pharmaceutical ingredients (APIs), including micronized, granulated, salt and free-base forms. Both soluble and insoluble drugs have been successfully compounded into solutions and suspensions which can be further processed into a dissolvable film. The intended dose is achieved by determining and precisely controlling the size and thickness of the final film.
