Results presented at the annual meeting of the American Academy of Pain Management showed that a lidocaine/tetracaine patch relieved pain associated with shoulder impingement syndrome, according to a Medscape report.
The patch is already approved to provide analgesia for venous access and dermatologic procedures and includes an iron oxide that generates heat when exposed to oxygen. This drives the anesthetics deeper into the tissue, said Richard Radnovich, DO, lead author from the Injury Care Medical Center in Boise, Idaho.
In the two-week study of 20 adults, more than half of patients showed at least a three-point reduction on the Numeric Pain Rating Scale.
