Key Terms

sublingual film, anaphylaxis, epinephrine, diastolic blood pressure, +2 more

6 terms

sublingual film medical

"Anaphylm™ (dibutepinephrine) sublingual film achieved clinically relevant..."

A sublingual film is a thin, dissolvable strip placed under the tongue that releases medication so it can be absorbed directly into the bloodstream through the mouth’s tissue. For investors, the delivery method matters because it can speed onset, avoid swallowing or injections, simplify dosing and manufacturing, and affect patient preference and regulatory approval — all factors that influence a product’s market potential and cost structure.

anaphylaxis medical

"product candidate Anaphylm™ ... for the treatment of severe allergic reactions, including anaphylaxis"

Anaphylaxis is a sudden, severe allergic reaction in which the body's defense system overreacts to a trigger (like a drug, food, or insect sting), causing widespread symptoms such as difficulty breathing, low blood pressure, and shock; it can be life‑threatening without prompt treatment. Investors care because anaphylaxis risks can affect a drug or product's safety profile, regulatory approval, liability exposure and market acceptance—similar to a sprinkler system going off and damaging the whole house rather than just one room.

epinephrine medical

"alternative to injectable epinephrine. Designed to address the practical..."

Epinephrine, also known as adrenaline, is a fast-acting hormone and medication used to stimulate the heart, open airways and tighten blood vessels during life-threatening emergencies like severe allergic reactions, asthma attacks and cardiac arrest. Investors care because its clinical use and demand drive sales of drug products and delivery devices, influence regulatory approvals and supply chains, and can quickly affect revenue and stock value when shortages, new formulations or policy changes occur.

diastolic blood pressure medical

"no diastolic blood pressure dip following sublingual administration of Anaphylm"

Diastolic blood pressure is the lower number in a blood pressure reading, measuring the force of blood against artery walls while the heart is resting between beats — like the baseline pressure in a garden hose when the pump pauses. It matters to investors because persistent abnormalities signal health risks that can influence healthcare costs, insurance liabilities, workforce productivity, and the outcomes or market value implications of medical treatments and clinical trials.

hemodynamic response medical

"impact on hemodynamic response when treating anaphylaxis"

Hemodynamic response is the way blood flow, pressure, and heart activity change when the body reacts to a drug, procedure, or disease — imagine a plumbing system adjusting flow and pressure when a valve is opened or closed. Investors care because these changes reveal how a treatment affects the cardiovascular system, influencing safety, effectiveness, regulatory approval, trial outcomes, and the commercial prospects of drugs or medical devices.

plasma concentrations medical

"achieved clinically relevant epinephrine plasma concentrations without diastolic..."

Plasma concentrations measure how much of a drug or biological marker is present in the liquid part of blood at a given time, like how much sugar is dissolved in a glass of water. Investors care because these levels show whether a treatment reaches the body in the right amount to work safely and consistently; that information drives clinical success, regulatory approval, dosing decisions and commercial value.

WARREN, N.J., Feb. 20, 2026 (GLOBE NEWSWIRE) -- Aquestive Therapeutics, Inc. (NASDAQ: AQST) (“Aquestive” or the “Company”), a pharmaceutical company advancing medicines to bring meaningful improvement to patients' lives through innovative science and delivery technologies, today announced that multiple poster presentations highlighting results from the investigational use of its product candidate Anaphylm™ (dibutepinephrine) sublingual film for the treatment of severe allergic reactions, including anaphylaxis, will be featured at the 2026 American Academy of Allergy, Asthma and Immunology (AAAAI) Annual Meeting. The meeting will take place February 27-March 2, 2026, in Philadelphia, PA.

“We are pleased to present additional clinical data at AAAAI highlighting Anaphylm’s differentiated profile,” said Daniel Barber, President and Chief Executive Officer of Aquestive. “These results build on our work to date, which is substantial and underscores Anaphylm’s potential to deliver clinically meaningful outcomes while offering an easy-to-carry alternative to injectable epinephrine. Designed to address the practical and psychological barriers that have prevented consistent epinephrine carriage and use for decades, Anaphylm has the potential to transform anaphylaxis management. Allergy patients need continued innovation designed to overcome well-understood preparedness and treatment barriers.”

“A dip in diastolic blood pressure after treating anaphylaxis with epinephrine is a serious clinical concern,” said Matthew Greenhawt, MD, MBA, MSc, lead author of one of the poster presentations. “Our data show no diastolic blood pressure dip following sublingual administration of Anaphylm – a clinically notable finding that advances our understanding of sublingually delivered epinephrine’s impact on hemodynamic response when treating anaphylaxis.”

Poster presentation details are as follows:

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 Unites States Food and Drug Administration (FDA), Anaphylm would be the first and only oral medication for the rescue 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.
