Scientists from the University of Nottingham have high confidence that a new, as yet unnamed drug may be as big and efficacious as ibuprofen. In 2002, the research team found 2 forms of a vascular endothelial growth factor (VEGF) protein—one that assists the growth of blood vessels and one that blocks it.
Continued research lead to the uncovery that one form of VEGF causes pain and the other prevents pain. The new drug will focus on the VEGF that controls blood vessel regrowth in injury-damaged tissues. Although still in its early stages, the drug may have a huge implication in the treatment of pain.
