Patent No. EP3613421 (titled "Dry Powder Inhaler And Methods Of Use") was filed by Aspeya on Mar 15, 2013. The application was issued on May 3, 2023.
Reducing the risk of thromboembolic events like heart attack or stroke by inhaling very low doses of aspirin using a dry powder inhaler. The doses are much lower than traditional oral aspirin, ranging from 2 mg to 10 mg. This enables faster absorption and action compared to oral aspirin due to avoiding the first pass effect in the gut. The low doses by inhalation also mitigate bleeding risks associated with higher aspirin doses.
