Use of Isoquercetin in the Treatment of Prurigo Nodularis
Abstract
Atopic dermatitis and prurigo nodularis result from complex interactions between the skin, the immune system, and the external environment. The pruritus associated with these conditions greatly impacts patients' quality of life and lacks uniformly effective treatment. A 57-year-old patient presented with severe atopic dermatitis and subsequent prurigo nodularis refractory to numerous standard therapies. The supplement isoquercetin was initiated and he noted significant, sustained reduction in his pruritus after only four weeks. Isoquercetin is a glycoside derivative with antihistamine properties of quercetin, a natural polyphenol flavonoid found in many plants. It may offer itch relief in patients who have failed more conventional therapies. J Drugs Dermatol. 2017;16(11):1156-1158..
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
