Volume of Distribution
After a single oral dose of 2 mg/kg to 4 subjects, average peak plasma concentrations of about 0.05 mg/L and 0.03 mg/L were attained in 5 h for unchanged drug and norchlorcyclizine, respectively. After oral administration of 50 mg 3 times a day for 6 days, plasma concentrations of norchlorcyclizine of 0.05 to 0.11 mg/L were reported on the first day after the cessation of treatment and plasma concentrations of 0.02 to 0.04 mg/L were found on the 10th day after cessation of treatment [Kuntzman et al. 1973].
Elimination Route
Readily absorbed after oral administration and widely distributed throughout the body. Metabolised by N-demethylation to form norchlorcyclizine and by N-oxidation.
Half Life
about 12 h.
Elimination Route
Slowly excreted in the urine; measurable amounts of norchlorcyclizine have been detected in the urine for up to 3 weeks after the cessation of chronic oral administration. About 0.5% of a single dose is excreted in the urine as the N-oxide.
