Both abametapir and abametapir carboxyl are high protein-bound in plasma, although the specific proteins to which they bind are unclear. Following topical administration, abametapir is 91.3-92.3% protein-bound and abametapir carboxyl is 96.0-97.5% protein-bound.

Abametavir has been shown to inhibit all stages of embryo development in both head and body lice by interfering with enzymes critical to this process. It is relatively unique amongst lice treatments in that it requires only a single application, whereas many current therapies require two applications, due to its exceptional potency and unique mechanism. Its predominant metabolite, abametapir carboxyl, has a prolonged residence time in the body, with an estimated half-life of 71 ± 40 hours or longer in adults - as this metabolite has been shown to inhibit cytochrome P450 enzymes _in vitro_, the use of substrates of CYP3A4, CYP2B6, or CYP1A2 should be avoided for two weeks following the administration of abametapir. Abametapir lotion is formulated with [benzyl alcohol], which has been associated with significant toxicity following unintentional systemic exposure, particularly in neonates and low birth weight infants. Benzyl alcohol-containing formulations should not be administered to patients <6 months of age, and should be administered to pediatric patients cautiously and under direct supervision of an adult to mitigate the risk of unintentional oral ingestion.

There are several metalloproteinases (enzymes requiring metal co-factors to function) involved in the process of louse egg hatching and survival. _In vitro_ studies have demonstrated that metal-chelating agents can inhibit the activity of these proteins, and may therefore be valuable pediculicidal agents. Abametapir is a metalloproteinase inhibitor that targets louse metalloproteinases which are critical to their development and hatching.
