Abametapir is a newly FDA-approved, single-application treatment for head lice in patients aged 6 months and older. Abametapir chelates heavy metal cations and inhibits metalloproteinases critical to louse ova development, hatching, and adult survival. Abametapir lotion, 0.74%, demonstrated significant ovicidal activity against head lice eggs with a single application.

Sample Use Guides

Apply XEGLYZE to dry hair in an amount sufficient (up to the full content of one bottle) to thoroughly coat the hair and scalp. Avoid contact with eyes. Massage XEGLYZE into the scalp and throughout the hair; leave on the hair and scalp for 10 minutes and then rinse off with warm water. Treatment with XEGLYZE involves a single application.
Route of Administration: Topical
In the in vitro pharmacology screen, 10 uM abametapir inhibited the activity of cyclooxygenase-1 by 52.3% and activity of MMP-9 by 24.4%.
