Oral formulation for kappa opioid receptor agonist
A recent patent application (Publication Number: US20230381265A1) discloses a novel formulation designed for the oral delivery of a kappa opioid receptor agonist. The formulation includes a particle containing the kappa opioid receptor agonist and an oligosaccharide, with the agonist embedded in the oligosaccharide. Specifically, the kappa opioid receptor agonist CR845 is mentioned, along with the oligosaccharide trehalose. Additionally, the formulation may include absorption enhancers such as sodium caprate, various excipients, and carriers to enhance efficacy and bioavailability.
Moreover, the patent application outlines a method for manufacturing the formulation, involving spray drying a mixture of the agonist and oligosaccharide to form particles or coating the mixture onto beads or microbeads. The method also includes encapsulating the coated beads or microbeads in a capsule, with the option of adding an enteric coating for specific delivery requirements. This innovative approach aims to improve the oral delivery of kappa opioid receptor agonists, potentially enhancing their therapeutic effects and patient compliance.
