Hydrocodone primarily binds to and activates the mu-opioid receptor in the central nervous system (CNS). This leads to analgesia, euphoria, respiratory depression, miosis, decreased gastrointestinal motility, cough suppression and physical dependence. Hydrocodone is converted to hydromorphone by the cytochrome P450 enzyme CYP2D6."}]
