Even if Botox's mechanism isn't always well understood and some of its off-label uses are still unproven, interest in the drug isn't likely to wane. "Botox is a big cash cow for the physicians' practices," says Ronny Gal, an investment analyst at Sanford C. Bernstein who has watched the drug closely for more than a decade. "When I talk to physicians, they say, 'Botox is not a problem. It works and gives you the result you want.' If it works for depression and atrial fibrillation, it could be massive."
BTX-A has also been used in the treatment of gummy smiles, the material is injected into the hyperactive muscles of upper lip, which causes a reduction in the upward movement of lip thus resulting in a smile with a less exposure of gingiva. Botox is usually injected in the three lip elevator muscles that converge on the lateral side of the ala of the nose; the levator labii superioris (LLS), the levator labii superioris alaeque nasi muscle (LLSAN), and the zygomaticus minor (ZMi).
Scientists at the University of Granada have confirmed that injecting a local anesthetic or botulinum toxin (botox) into certain points named "trigger points" of the pericraneal and neck muscles reduce migraine frequency among migraine sufferers. University of Granada researchers have identified the location of these trigger points -which activation results in migraine- and their relationship with the duration and severity of this condition.
