Metabolite Identification
Common Name4-Hydroxyclonidine
Description4-Hydroxyclonidine is a metabolite of Clonidine. Clonidine (trade name Kapvay or Nexiclon) is a sympatholytic medication used to treat high blood pressure, ADHD, anxiety/panic disorder, and certain pain conditions. It is classified as a centrally acting α2 adrenergic agonist. An alternative hypothesis that has been proposed is that clonidine acts centrally as an imidazoline receptor agonist. (Wikipedia)
