ARx Buccal, Sublingual and Mucosal Thin Films

Buccal, sublingual and mucosal thin films from ARx, LLC provide added bioavailability benefits and fast API absorption compared to traditional dosage forms.

ARx custom formulates and manufactures drug-loaded mucosal film systems, designed to bond to challenging mucosal tissues for specified periods of time, while proving comfortable for the patient. The systems may be single or multi layer and formulated for removal upon treatment, or to completely erode at a pre-determined time. Multi-layer systems provide an added benefit in insuring API penetration through mucosal tissue before the entire system is dissolved.

Dissolvable films 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 are further processed into a dissolvable film. Active concentrations of larger particle sized compounds are possible up to 50% of the final unit mass; the intended dose is achieved by determining and precisely controlling the size and thickness of the final film.
