Nutriband said in a March 30, 2026 press release that it has selected a commercial brand name for its lead product, an abuse deterrent fentanyl transdermal system, and will submit the name to the FDA for approval. The filing does not report revenue, earnings, or guidance, and the company's $80 million to $200 million peak annual US sales estimate is a potential figure, not a forecast, so the news is a development step toward regulatory review.

The proposed name and labeling will go to the FDA and other international regulators, and the name is being submitted to the USPTO for trademark registration.
