💊 Profile

Fumaric acid and some of its derivatives have been used in the treatment of psoriasis and other skin disorders. Fumaric acid is also used as an acidifier and flavouring agent in foods.

Skin disorders.

Fumaric acid, its sodium salts, and derivatives such as dimethyl fumarate, monoethyl fumarate (ethyl hydrogen fumarate), and octil hydrogen fumarate have been used, both topically and systemically, in the treatment of psoriasis and other skin disorders. Dimethyl fumarate appears to be the most active compound given orally but combination with various salts of monoethyl fumarate has been claimed to improve efficacy.1-6 However, there have been reports of acute renal failure associated with treatment and the German Federal Office of Health has expressed the opinion that the available evidence did not establish the value of fumaric acid derivatives in psoriasis or other skin disorders.7 A subsequent retrospective analysis of 41 patients who received fumaric acid esters orally, for between 1 and 14 years, suggested that these drugs might be effective,8 and a later review suggested that they may be of value in refractory psoriasis.9 Reported adverse effects in the earlier analysis8 were generally mild, with only 1 case of elevated serum creatinine; however, lymphocytopenia was noted in 76% of patients and treatment consequently stopped in 4 patients. Other adverse effects with oral therapy have included disturbances of liver func tion,3,10 gastrointestinal effects,2-4,10,11 and flushing.2-4,10,11 There has been a report of exanthema in a patient receiving dimethyl fumarate for lichen planus.12
