KELOWNA, BC / ACCESSWIRE / December 29, 2022 / Lexaria Bioscience Corp. (Nasdaq:LEXX)(Nasdaq:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms is pleased to announce its continued accumulation of international patent recognition with the receipt of its first granted patent in Canada, which is its 28^th granted patent worldwide.

Canadian Patent #3,093,414 is the first granted patent from Lexaria's sixth patent family and is entitled "Transdermal And/Or Dermal Delivery Of Lipophilic Active Agents". The patent is for improved compositions and methods for transdermal and dermal delivery of cannabinoids, including cannabidiol ("CBD") and tetrahydrocannabinol ("THC"). Similar patent applications for skin-based delivery of DehydraTECH formulations remain pending in many other countries.

Effective skin-based administration opens up new possibilities for pharmaceutical and medical applications of CBD and other cannabinoids for peripherally focused disease conditions in the body, or for those people who have difficulty with oral dosage forms. In countries where CBD is legal for non-pharmaceutical use, superior skin-penetrating advantages could prove to be commercially valuable.

In a 2018 study, Lexaria's DehydraTECH-CBD demonstrated almost a 1,900% increase in CBD permeability through human skin compared to a control formulation that was devoid of any commercial penetration enhancers. When compared to the highest performing commercial penetration enhancer that was evaluated in that study, DehydraTECH-CBD still offered a 225% increase in CBD permeability through the skin. Lexaria's DehydraTECH-CBD was also the fastest acting for absorption into the epidermis, dermis and through the skin into the representative systemic circulation.

Since 2018 Lexaria has developed significantly more powerful versions of DehydraTECH-CBD tested orally that have not yet been tested in skin penetration studies, but that may offer even further enhanced CBD delivery topically compared to its compositions tested to-date. Lexaria's DehydraTECH-CBD formulated topically also exhibits nearly zero unwanted odor often associated with cannabinoid extracts, without using any masking perfumes or other artificial agents to mask odor.

Delivery of drugs through the skin has been both an attractive and challenging area for research, as one of the principle functions of skin is to provide a barrier to the transportation of water and substances potentially harmful to normal homeostasis. The skin helps to prevent the entry of harmful substances into the body but can also be used to administer beneficial substances. The global skin-care market is estimated to be over $121 billion in annual sales, not including pharmaceutical applications.
