A recently filed patent (Publication Number: US20230293436A1) describes an inhalable dry powder pharmaceutical composition for the treatment of diseases or disorders. The composition includes a neuroactive agent and 3,6-di(N-fumaryl-4-aminobutyl)-2,5-diketopiperazine, or a pharmaceutically acceptable salt thereof.

The neuroactive agent in the composition can be an immunomodulating agent, an inflammatory mediator, or a synthetic organic compound. The composition also includes microparticles with a diameter of less than 10 µm, with a significant portion (about 35% to about 75%) having an aerodynamic diameter of less than 5.8 µm. These microparticles are characterized by assemblages of crystalline plates with irregular surfaces.

In addition to the active ingredients, the composition may contain one or more pharmaceutically acceptable carriers and/or excipients.

The patent also describes a method of treating a disease or disorder by administering the inhalable dry powder pharmaceutical composition to a subject. The method follows the same principles as the composition, including the use of a neuroactive agent, microparticles with specific size characteristics, and the inclusion of carriers and/or excipients.

Overall, this patent presents a novel inhalable dry powder pharmaceutical composition that combines a neuroactive agent with 3,6-di(N-fumaryl-4-aminobutyl)-2,5-diketopiperazine. The composition's unique characteristics, such as the size and shape of the microparticles, make it suitable for the treatment of various diseases and disorders. The method of administration described in the patent provides a potential therapeutic approach for delivering the composition to patients.
