Lexaria Granted Strategically Important New US Patent For DehydraTECH-Nicotine Including Oral Pouch Products

• More countries are banning e-cigarettes as novel oral products gain traction

KELOWNA, BC / ACCESSWIRE / July 19, 2023 / Lexaria Bioscience Corp. (NASDAQ:LEXX)(NASDAQ:LEXXW) (the "Company" or "Lexaria"), a global innovator in drug delivery platforms announces it has been granted a strategically important new patent in the oral nicotine sector by the United States Patent and Trademark Office ("USPTO").

US patent #11,700,875 Compositions and Methods For Sublingual Delivery of Nicotine includes claims for many types of nicotine, including nicotine benzoate, nicotine ditartrate, nicotine citrate, nicotine polacrilex, and many others, for use in sublingual delivery formats like oral pouches. Lexaria's superior DehydraTECH processing and sublingual compositions have now been recognized not only through exceptional scientific study results, but also by the USPTO.

DehydraTECH-nicotine has already shown in multiple sets of animal testing that it can be delivered to the bloodstream up to 10-times to 20-times faster at up to 10-fold higher levels of nicotine into blood plasma from oral absorption than concentration matched controls. Speed of onset is of vital importance to nicotine users.

This US-awarded patent is also progressing as a patent application through other jurisdictions internationally. This US patent award and the international patent applications are supported in part by the superior pharmacokinetic blood plasma data generated by Lexaria in its animal studies conducted from 2017 through 2021. Lexaria considers the work completed by competitors to be substantially inferior when it is limited to indirect theoretical extrapolations of nicotine absorption into the bloodstream and/or subjective commentary from small numbers of people, as opposed to Lexaria's rigorous scientific examinations.

Lexaria's new patent builds nicely upon its growing patent portfolio in the oral nicotine delivery sector including the white pouch category for both sublingual and buccal tissue delivery, together with its previous patent filings specific to nicotine dating back to 2019, as well as its foundational DehydraTECH patent filings dating back to 2016.

The oral nicotine pouch category is of intense interest to Lexaria and the nicotine products industry, and its growth is due in part to its reduced risk health outcomes as noted by the Food and Drug Administration. This delivery method, in the white pouch format specifically, which avoids harmful lung outcomes experienced by smokers or vapers, involves absorption primarily through the buccal and sublingual tissues of the mouth, of purified nicotine that has been separated from most other harmful compounds in the tobacco leaf. The global market for the oral nicotine pouch category was US$4.69 billion in 2022 and is growing at a rapid CAGR of 13.4% and is expected to reach $11.91 billion in 2029.

Meanwhile, at least 37 countries have banned the selling of e-cigarettes, the devices used in vaping. This represents a cumulative population of over 2.3 billion people. Nicotine vaping was originally hoped to help wean people off cigarette use but has had mixed results in doing so, and vaping has also been associated with serious health risks. Nicotine vaping is becoming increasingly controversial and is severely limited in certain countries and was, for instance, recently banned in Australia and is either banned or restricted in many other countries.

Lexaria's DehydraTECH-nicotine is now patent granted for oral nicotine delivery in the U.S., Canada and Australia, and pending in numerous other countries. The white pouch category is one of the fastest growing, tobacco-free alternatives to smoking and vaping. White pouches emit no smoke, odors or vapor that can affect nearby persons and are therefore a superior personal nicotine delivery method.

The dangers of cigarette smoking are well known and result in the death of 7 million people per year. Lexaria's DehydraTECH-powered purified nicotine white pouch formulation contains no tobacco.
