OPIOIDS are Powerful Analgesics for Treating Many Types of Pain…BUT

• They can result in addiction

• Tolerance can develop, necessitating increasing dose to achieve desired effect

• Recent data indicate that the prescribing of opioids by clinicians has increased threefold in the last 20 years, contributing to the problem of prescription opioid abuse

• They can produce significant (and sometimes lethal) side effects (including constipation, nausea and respiratory depression)

And women’s reports of pain were more likely to be dismissed

Women appeared to suffer more pain in many categories

Source: CDC Vital Signs July 2013.

• Women are more likely to have chronic pain, be prescribed prescription painkillers, be given higher doses, and use them for longer time periods than men

• Women may become dependent on prescription painkillers more quickly than men

The Prescription Painkiller Problem Affects Women In Different Ways Than Men

• Women may be more likely than men to engage in “doctor shopping”

What Should We Be Working On to Achieve Safer and More Effective Treatment?

• Learning more about the neural mechanisms underlying chronic pain

• Exploring genomic underpinningsof chronic pain and its treatment

• Developing less abusable analgesics

• Identifying effective non-pharmacologicalinterventions for chronic pain

•Affects prenatal andpostnatal growth

• Increases the risk ofdevelopmental and behavioral deficits

Increasing Costs for Neonatal Exposure

NIH Helping to End Addiction Long-term (HEAL) Initiative

• $500M/year funding provides opportunity to:– Improve prevention and treatment strategies,

both in clinic and real world settings, for opioid misuse and addiction

– Enhance pain management by furthering understanding of neurobiology of pain, developing non-addictive treatments, and building a Clinical Trial Network for pain

– Develop shared platforms through public and private partners

• Coordinating with Surgeon General, other HHS agencies, local government officials

All Hands on Deck!

HEAL Research Projects on Opioid Use Disorder (OUD)• Develop new treatments for opioid addiction, including more flexible

medications options and novel immunotherapies to opioids

• Advance clinical trials for Neonatal Opioid Withdrawal syndrome to improve short- and long-term outcomes for infants and children

• Enhance the NIDA Clinical Trials Network to build linkages with primary care, emergency departments, and the justice system

• Establish a Justice Community Opioid Innovation Network

• Optimize effective treatments for OUD in the field through the HEALingCommunities Study

HEAL Research Projects on Pain Management

• Pinpoint acute to chronic pain signatures to identify those at risk for transition to chronic pain

• Discover and validate novel treatments for pain

– Work across entire NIH to include all therapeutic development programs

– Identify potential small molecules, biologics, devices, and natural products

– Develop preclinical screening platforms for testing

– Move successful compounds/devices to clinical trials
