Charlotte, N.C.-based Balanced Pharma, received a second patent for its dental cartridge technology from the U.S. Patent and Trademark Office.
The cartridge allows dentists to administer local anesthesia that is faster-acting and less painful for patients, according to a May 25 news release.
The anesthesia comes in a standard dental cartridge, making it so there is no new training or equipment required.
The product is still in development and has not been approved by the FDA and is not available for sale in the U.S., the release said.
