Naftidrofuryl (INN), also known as nafronyl or as the oxalate salt naftidrofuryl oxalate or nafronyl oxalate, is a vasodilator used in the management of peripheral and cerebral vascular disorders. It is also claimed to enhance cellular oxidative capacity. The drug act as a selective antagonist of 5-HT2 receptors (with action as an inverse agonist of the 5-HT2A receptor specifically characterized).[1][2][3] Naftidrofuryl is also licensed for the treatment of intermittent claudication due to peripheral arterial disease.

Naftidrofuryl is marketed under a variety of trade names, including Artocoron, Azunaftil, Di-Actane, Dusodril, Enelbin, Frilix, Gevatran, Iridus, Iridux, Luctor, Nafti, Naftilong, Naftodril, Nafoxal, Praxilene, Sodipryl retard, and Vascuprax.

Historically, it has been used to treat sudden idiopathic hearing loss and acute tinnitus.[4]

Naftidrofuryl may be effective for relieving the pain of muscle cramps.[5]
