AVTOZMA vs PROMETHAZINE DM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
AVTOZMA is a monoclonal antibody that binds to and inhibits the activity of interleukin-6 (IL-6), blocking its interaction with the IL-6 receptor and thereby reducing inflammation and immune response.
Promethazine is a phenothiazine derivative that acts as a histamine H1 receptor antagonist, antiemetic via blockade of dopamine D2 receptors in the chemoreceptor trigger zone, and sedative via central anticholinergic effects. Dextromethorphan is an NMDA receptor antagonist and sigma-1 receptor agonist, suppressing cough by central action on the cough center.
AVTOZMA is not a recognized drug; no standard dosing available.
2 teaspoonfuls (10 mL) orally every 4-6 hours, not to exceed 8 teaspoonfuls (40 mL) per 24 hours.

Terminal elimination half-life is 12 hours in healthy adults; clinically, this supports twice-daily dosing.
16-19 hours (terminal); note: effect may last longer due to active metabolites and tissue binding
Renal excretion of unchanged drug accounts for approximately 70% of elimination; biliary/fecal excretion accounts for 30%.
Renal (70-80% as metabolites, <1% unchanged); biliary/fecal (20-30%)
