A Phase 1 Assessment of the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of (2R,6R)-Hydroxynorketamine in Healthy Volunteers.

(R,S)-Ketamine (ketamine) is a dissociative anesthetic that also possesses analgesic and antidepressant activity. Undesirable dissociative side effects and misuse potential limit expanded use of ketamine in several mental health disorders despite promising clinical activity and intensifying medical need. (2R,6R)-Hydroxynorketamine (RR-HNK) is a metabolite of ketamine that lacks anesthetic and dissociative activity but maintains antidepressant and analgesic activity in multiple preclinical models.

Characteristics of older adults receiving opioids in primary care: treatment duration and outcomes.

Outcomes associated with opioid use in the treatment of chronic noncancer pain in older adults: a systematic review and meta-analysis.

This systematic review summarizes existing evidence regarding the efficacy, safety, and abuse and misuse potential of opioids as treatment for chronic noncancer pain in older adults. Multiple databases were searched to identify relevant studies published in English (1/1/80-7/1/09) with a mean study population age of 60 and older. Forty-three articles were identified and retained for review (40 reported safety and efficacy data, the remaining 3 reported misuse or abuse outcome data).
