Rescheduling hydrocodone combination products: Impact on patients receiving long-term HCP therapy in a large chain pharmacy-A statewide assessment.

This study aimed to evaluate the rescheduling of hydrocodone combination products (HCPs) from schedule III (CIII) to schedule II (CII) in patients receiving chronic HCP therapy. This study was a retrospective cohort analysis of administrative pharmacy data from 118 statewide pharmacies from a retail chain in Tennessee. HCP filling histories were analyzed on patients meeting enrollment criteria from July 1, 2014, to October 1, 2015. The average number of tablets dispensed, daily average of the number of tablets dispensed, and monthly average of morphine milligram equivalents (MME) dispensed were compared for the periods of July 1, 2014, to October 5, 2014 (enrollment period before schedule change) and October 6, 2014, to October 1, 2015 (period following schedule change) using a pooled t test. A total of 4536 patients met the inclusion criteria. Of these 4536 patients, 60.6% were female, and 40.4% were male, with an average age of 58 years (patients included in this study were between the ages of 18 and 99 years). The total number of hydrocodone tablets dispensed in the 12 periods after the schedule change dropped from 467,217 to 259,327, a 45.5% reduction (P < 0.001). Total MME decreased from 4.11 to 2.29 million, a 45.3% reduction (P < 0.001). The number of study participants still receiving an HCP at the end of the study decreased to an average of 2736 across the 12 periods following the schedule change, a 40% reduction. HCP dispensing and use decreased among patients receiving chronic opioid treatment from a large corporate statewide community pharmacy in Tennessee after a schedule change from CIII to CII. Monthly sums of total tablets dispensed, average daily tablets dispensed, MME, and average daily MME calculated from July 1, 2014, to October 1, 2015, all experienced statistically significant reductions.
