IMPEKLO vs LAMISIL AT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
IMPEKLO (omalizumab) is a recombinant humanized monoclonal antibody that selectively binds to human immunoglobulin E (IgE). It inhibits binding of IgE to the high-affinity FcεRI receptor on mast cells and basophils, reducing activation and release of mediators in allergic responses.
Terbinafine inhibits squalene epoxidase, an enzyme in the fungal ergosterol biosynthesis pathway. This leads to accumulation of squalene and depletion of ergosterol, disrupting fungal cell membrane integrity and causing cell death.
IMPEKLO is not a recognized pharmaceutical agent. No dosing information available.
Terbinafine 250 mg orally once daily for 6 weeks for fingernail onychomycosis or 12 weeks for toenail onychomycosis. Topical: 1% cream applied once daily for 1 week for tinea pedis; 1% solution applied once daily for 1 week for tinea corporis/cruris.

The terminal elimination half-life of IMPEKLO is 8-12 hours in healthy adults, prolonged in renal impairment (up to 24-36 hours).
The terminal elimination half-life is approximately 11-17 hours in healthy adults; however, it increases to about 200-400 hours in the distribution phase from tissues (e.g., skin, adipose). Steady-state is reached after 10-14 days of oral dosing.
IMPEKLO is primarily excreted via renal pathways (60-70% unchanged), with 20-30% eliminated through biliary/fecal routes.
Terbinafine is extensively metabolized in the liver; approximately 80% of a dose is excreted in urine as metabolites, and 20% in feces. Less than 1% is excreted unchanged in urine.
