ABSTRACT: Background
Chronic pain patients on long-term opioid therapy (LTOT) may be at elevated risk for developing conditioned opioid cue-reactivity as their prescribed dosing schedules simultaneously function as fixed reinforcement schedules. Since opioids are typically consumed orally during LTOT, it stands to reason that opioid cue exposure might elicit conditioned salivary responses. However, no study has examined salivary cue-reactivity among opioid users during in-vivo exposure to their own prescription opioid medication.Methods
Two samples (N = 68, N = 39) of chronic pain patients on LTOT were recruited from primary care and specialty care clinics. Study 1 aimed to determine whether chronic pain patients receiving LTOT exhibited salivary cue-reactivity to their prescribed opioid. Study 2 was a pilot study that aimed to assess the effects of behavioral treatment on chronic pain patients' salivary cue-reactivity.Results
In Study 1, exposure to the patient's own prescribed opioid resulted in significantly greater increases in salivation and cue-elicited craving than exposure to a neutral cue. In Study 2 participants who were randomized to an 8-week Mindfulness-Oriented Recovery Enhancement intervention evidenced significantly greater decreases in opioid cue-reactivity than participants in an active control condition as evidenced by both reduced salivation and craving ratings.Conclusions
Study findings demonstrate salivation may serve as a useful, objective index of opioid cue-reactivity. With further refinement of this task, conditioned salivary response could be used to identify especially vulnerable patients, who then could be targeted with a personalized medicine approach for selective and intensive prevention/treatment interventions to preempt escalation of opioid use to opioid misuse and OUD.
