How it works

This product’s leaflet is published as a scanned document. This section quotes the US prescribing label for the same active substance (dimethyl fumarate). It describes the substance, not this Bulgarian product — its uses and doses can differ.

The mechanism by which dimethyl fumarate (DMF) exerts its therapeutic effect in multiple sclerosis is unknown.

DMF and the metabolite, monomethyl fumarate (MMF), have been shown to activate the Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway in vitro and in vivo in animals and humans.

How the body breaks it down

In humans, dimethyl fumarate is extensively metabolized by esterases, which are ubiquitous in the gastrointestinal tract, blood, and tissues, before it reaches the systemic circulation.

With food

Following administration of dimethyl fumarate delayed-release capsules 240 mg twice a day with food, the mean C max of MMF was 1.87 mg/L and AUC was 8.21 mg.hr/L in MS patients.
