<unk>  (trade name Nimelan), also known as N-allylnormorphine<unk> , dinicotinoylnalorphine, or niconalorphine, is a semisynthetic, mixed opioid agonist-antagonist which is described as a narcotic antagonist but may produce limited analgesia and sedation at higher doses in opioid naive patients (with limited euphoria and dependence liability). It is the 3,6-dinicotinate ester of<unk> , and is therefore the<unk>  analogue of nicomorphine (which is the 3,6-dinicotinate ester of morphine). As<unk>  is only regulated at the Rx (prescription required) drug, it would be legal to possess with a valid prescription should a patient manage to acquire it.
