Factors Associated With Manufacturer Drug Coupon Use at US Pharmacies

This is the authors' abstract. We don't add key points for this paper.

In this cohort study of transactional pharmacy claims, higher mean per-patient total cost within a class was significantly associated with the likelihood of coupon use, but not patient out-of-pocket cost. Manufacturers' coupons were more likely to be used for expensive later-in-class-entrant products facing within-class competition where coupon use was prevalent.
