title: Topical rosacea therapy: the importance of vehicles for efficacy, tolerability and compliance.
abstract: Many topical medications are available for the treatment of papulopustular rosacea. While treatments contain metronidazole, azelaic acid, or sodium sulfacetamide-sulfur as the active ingredient, the composition of the vehicle formulations varies widely. These vehicles come in gels, creams, lotions and foams; some ingredients are common to many vehicles, while some vehicles contain unique ingredients designed to optimize skin penetration and delivery of the active drug to its target. Vehicles can also influence tolerability, which is always a concern in patients with heightened skin sensitivity, and compliance, which is typically lower for topical treatments than oral treatments. Ideally, the vehicle of any rosacea treatment should enhance drug delivery, be nonirritating and be easy to use. Ingredients that help repair barrier function are also desirable. This review will focus on the key components of the vehicles from the most commonly used topical therapies for papulopustular rosacea and how vehicle formulations influence the delivery of active ingredient, skin barrier repair, tolerability and compliance.
