title: Trends in on and off-label calcipotriene use.
abstract: Following its introduction in 1994, calcipotriene quickly became the single most prescribed medication for psoriasis according to National Ambulatory Medical Care Survey (NAMCS) data. Primarily through regulation of cellular differentiation, calcipotriene may be effective in dermatoses other than psoriasis. We characterize the clinical trends in the utilization of calcipotriene by analyzing a representative sample of visits to US physicians. Demographic characteristics, specialty of the provider, and off-label uses are reported. Calcipotriene was mentioned at 5.8 million of all NAMCS visits during the study period. Nearly 57% of mentions of calcipotriene were not linked to a diagnosis of psoriasis. Adjusted use for gender and race were relatively stable; there was a rise in non-psoriasis uses and use among non-dermatologists in 1997. Our findings support previous reports of the utility of calcipotriene in treating other dermatoses as witnessed by the numerous conditions for which its use was observed. Physicians and policy-makers should be aware of the role that this medication plays in the delivery of dermatologic care.
