About Anaphylm™ (dibutepinephrine) Sublingual Film Anaphylm™ (dibutepinephrine) Sublingual Film is a polymer matrix-based epinephrine prodrug product candidate. Anaphylm is similar in size to a postage stamp, weighs less than an ounce, and begins to dissolve on contact. No water or swallowing is required for administration. The packaging for Anaphylm is thinner and smaller than an average credit card, can be carried in a phone or wallet, and is designed to withstand weather excursions such as exposure to rain and/or sunlight. If approved by the United States Food and Drug Administration (FDA), Anaphylm would be the first and only oral rescue medication for the treatment of severe allergic reactions, including anaphylaxis. The Anaphylm trade name for AQST-109 has been conditionally approved by the FDA. Final approval of the Anaphylm proprietary name is conditioned on FDA approval of the product candidate.
