agent that undergoes direct N-glucuronidation by
UDP-glucuronosyltransferase isoenzyme UGT2B10 in a human subject
comprising administering an effective amount of an UGT2B10 modulator to
said human subject. A method for identifying compounds which are directly
metabolized by UGT2B10 or which act as UGT2B10 modulators is also
disclosed.
