Normethadone Action Pathway
smpdb.ca/view/SMP0126829Drug actionNormethadone is an opioid antitussive used to treat a cough associated with inflamed mucosa. Normethadone binds to mu opioid receptors, stimulating the exchange of GTP for GDP on the G-protein complex. As the effector system is adenylate...
