Examine Reveals Nasal Powder Epinephrine Supplies Superior Stability to EpiPens


Needle-free, nasal supply of epinephrine has been proven to be an efficient and secure remedy for anaphylaxis.

MILWAUKEE – Nasal powder formulations of epinephrine demonstrated superior stability and comparable plasma publicity to EpiPens based on new analysis being introduced on the 2024 American Academy of Allergy, Bronchial asthma & Immunology Annual Assembly.

“After greater than 100 years of medical use, a needle-free possibility for epinephrine lastly appears to be inside attain, because of new supply applied sciences mixed with efforts from regulatory companies to discover a scientifically sound growth path. The nasal amorphous powder expertise now we have developed gives each efficient absorption and glorious stability that will profit sufferers, making certain that the drug isn’t degraded when carried and continues to be efficient when wanted” says lead creator, Martin Jönsson, MSc Pharm.

In a 5-period, cross-over research with 40 wholesome volunteers, researchers evaluated the bioavailability and hemodynamic response of 4 1 mg powder formulations in comparison with a 0.3 mg EpiPen. Within the research, proprietary amorphous powder formulations had been developed utilizing spray-drying, and the steadiness of these formulations was evaluated underneath accelerated situations and in comparison with the EpiPen.

The preservative-free powder formulations had been secure underneath accelerated situations, with lower than 1% complete degradation over 12 months in comparison with 32% degradation for the EpiPen. Powder formulations of epinephrine had been quickly absorbed with comparable plasma ranges to EpiPens reached inside about 5-10 minutes. The research discovered that peak and early baseline adjusted publicity ranges had been additionally akin to the EpiPen, starting from an estimated 83% to 120% of EpiPen ranges relying on the system, and complete publicity was about 30% to 60% larger for the nasal powders. Onset of hemodynamic results, each blood stress and coronary heart fee, had been akin to these related to EpiPen utilization, with considerably larger improve in blood stress. The findings recommend nasal powder formulations of epinephrine demonstrated superior stability and comparable plasma publicity to EpiPens, making them an efficient remedy possibility for sufferers.

As remedy choices for anaphylaxis are at the moment restricted to parenteral autoinjectors, with needle-based administration that will deter well timed use, nasal epinephrine powders can tackle shortcomings of present autoinjectors, and make them a extra accessible possibility for sufferers sooner or later.
