Duobrii (halobetasol propionate and tazarotene) is a corticosteroid and retinoid combination indicated for the topical treatment of plaque psoriasis.
- Duobrii Lotion contains halobetasol propionate 0.01% and tazarotene 0.045%. It is the the first FDA approved combination of the two drugs - both widely used individually as topical treatments for psoriasis, with established safety profiles.
- Halobetasol propionate is available as a generic in a topical cream 0.05% formulation, and tazarotene is available as a generic in a topical cream 0.1% formulation.
- According to the results of a phase 2 study, the halobetasol propionate/tazarotene combination lotion was "consistently" more effective than its individual agents and vehicle in achieving treatment success.
- Duobrii Lotion is applied as a thin layer to the affected areas once daily.
- Tazarotene may cause birth defects if used during pregnancy. Females of reproductive potential should obtain a negative pregnancy test within two weeks prior to using Duobrii and must use an effective method of contraception during treatment to avoid pregnancy.
- Duobrii Lotion may cause photosensitivity reactions and increase the risk for sunburn. Patients should avoid natural and artificial sunlight, including sunlamps and tanning beds, and use sunscreen and wear a hat and protective clothing when outdoors to prevent sunburn during treatment with Duobrii.
- The most common adverse events reported in clinical trials include redness, itching, swelling, burning, stinging, application site pain, inflamed hair follicles (folliculitis), thinning of the skin (atrophy), peeling and rash.
