ObjectiveTo quantify the potential impact of reductions in positive subjective measures from human abuse liability studies on real-world rates of nonmedical use of prescription drugs and associated healthcare resource utilization and costs.DesignPositive subjective endpoints "overall drug liking," in-the-moment "drug liking," and "drug high" Emaxs (peak effects) were recorded from published studies. Nonmedical use data were obtained from the 2010 National Survey on Drug Use and Health (NSDUH) and Drug Abuse Warning Network surveys. Multivariate regressions evaluated the association between the positive subjective endpoints and nonmedical use rates, controlling for prescription volume, whether the drug is an opioid, and controlled substance schedule. A published budget-impact model was used to assess healthcare resource utilization and cost impacts of abuse-deterrent opioid formulations.ResultsA five-point reduction in overall drug liking/drug liking/drug high Emax was associated with a 0.25/0.10/0.05 (standard errors: 0.11/0.12/0.07) percentage point decrease in the NSDUH lifetime nonmedical use rates. Those decreases yielded a 11.3/4.2/2.1 percent reduction compared to the samples' lifetime nonmedical use rates of 2.21/2.38/2.36 percent. On the basis of a number of assumptions, these reductions were associated with private payer cost reductions for a morphine and oxycodone abuse-deterrent formulation in the ranges of $147.9-324.1 million and $230.7-958.7 million, respectively.ConclusionsReductions in overall drug liking were significantly associated with reduced real-world nonmedical use, healthcare utilization, and costs. Associations using drug high and drug liking were directionally consistent with this finding though not statistically significant. A reduction in positive subjective measures associated with an abuse-deterrent formulation has potential to reduce abuse and associated healthcare utilization and costs.
