Patent 11833157 was granted and assigned to Xeris Pharmaceuticals, Inc. on December, 2023 by the United States Patent and Trademark Office.
Embodiments of the invention are directed to formulations that provide a solution to the problem of small molecule (e.g., diazepam) precipitation at the injection site when administered as a highly-concentrated formulation. In certain aspects the formulations include at least one surfactant in a non-aqueous formulation, which prevents small molecule precipitation and improves the bioavailability of the drug by enhancing absorption into the systemic circulation.
