Treating depression in non-cancer pain found to be more effective when opioid (a pain killer) use is stopped completely.

‘Non-cancer patients suffering from depression who take anti-depression medications rather than opioids found to be more effective.’

Exploratory analysis found that patients who adhered to anti-depression medications and stopped taking opioids experienced a rapid and greater decline in depression symptoms compared with patients who did not stop taking opioids. 




"We can't be sure that a decrease in depression led to patients' choosing to stop opioid use and we know prospective studies are needed," Scherrer said. "Depression can worsen pain and is common in patients who remain long-term prescription opioid users. Our study should encourage clinicians to determine if their non-cancer pain patients are suffering from depression and aggressively treat patients' depression to reduce opioid use."
Long-term prescription opioid analgesic use (OAU) for chronic non-cancer pain is defined as daily or near-daily use for 90 days. Between 1.4 and 10 percent of patients with a new opioid prescription develop chronic OAU and a majority (65-80 percent) of patients who have persistent opioid analgesic use for 90 days are still taking opioids three to five years later.
These long-term patients are more likely than those that use opioids for a short term to develop opioid disorder and overdose. Chronic analgesic use is also associated with new depressive episodes and treatment-resistant depression.
"Effective depression treatment may break the mutually reinforcing opioid-depression relationship and increase the likelihood of successful opioid cessation," Scherrer said.

Scherrer and his co-authors used medical record data from 2000-2012 from the Veterans Health Administration (VHA).

The odds of opioid cessation were compared between patients with anti-depressant adherence versus non-adherence.
The anti-depression medications included monoamine oxidase inhibitors (MAOIs), selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), tricyclics (TCAs) and non-classified ADMs.
The study calls for additional research and treatment trials.
