SEATTLE - Receptor Life Sciences ("RLS”), a leading biopharmaceutical company developing FDA regulated oral and inhaled cannabinoid medicines, today announced that the United States Patent and Trademark Office has issued the Company a Patent for compositions comprising cannabinoids and the company's oral absorption enhancing excipients: U.S. Patent No. 10,588,974.

Receptor's excipients increase oral cannabinoid bioavailability, reduce time to onset and can be formulated as either liquid or solid dosage forms. These products are specifically designed to overcome the challenges of poor, highly variable absorption and long time to onset characteristic of currently available oral cannabinoid medicines.

"This patent provides strong patent coverage for RLS' oral delivery technology platform,” said Greg Wesner, Founder, CEO, and General Counsel, Receptor Life Sciences. "The patent provides a broad and versatile foundation for the development of a disruptive product line in oral cannabinoid medicines.”

"The simplicity and versatility of RLS oral delivery system allows clear differentiation from the numerous traditional approaches prevalent in the industry; and is based on an excipient granted FDA-approval in other products,” added Andrea Leone-Bay Founder and Chief Scientific Officer, Receptor Life Sciences.

Dr. Leone-Bay is an internationally recognized authority on inhaled dry powder and oral drug delivery technologies. The new patent is her 111th.
