IMPEKLO vs KETOZOLE
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.
Ketoconazole is an imidazole antifungal agent that inhibits fungal cytochrome P450 14α-demethylase, thereby blocking the conversion of lanosterol to ergosterol, a key component of the fungal cell membrane. This leads to increased membrane permeability and cell death.
IMPEKLO is not a recognized pharmaceutical agent. No dosing information available.
200 mg orally once daily with food.

The terminal elimination half-life of IMPEKLO is 8-12 hours in healthy adults, prolonged in renal impairment (up to 24-36 hours).
Terminal elimination half-life is approximately 2 hours (range 1.5–3.5 hours). Clinically, duration of antifungal effect extends beyond plasma half-life due to persistent tissue levels.
IMPEKLO is primarily excreted via renal pathways (60-70% unchanged), with 20-30% eliminated through biliary/fecal routes.
Primarily hepatic metabolism; renal excretion of unchanged drug <1%. Biliary/fecal excretion accounts for ~20-35% of metabolites.
