RecruitingPhase 2Drug trialThe Efficacy of Tranexamic Acid in the Treatment of Lichen Planus Pigmentosus and Erythema Dyschromicum PerstansThere are currently no effective treatments for lichen planus pigmentosus (LPP) and erythema dyschromicum perstans (EDP). Tranexamic acid, which may downregulate pigmentation through a reduction in plasmin, has been shown to decrease pigmentation in patients with melasma, another pigmentary disorder. Given that LPP, EDP, and melasma are all disorders of pigmentation with dermal involvement, it is possible that tranexamic acid can also reduce pigmentation in LPP and EDP as well.
