Ointments and lotions containing bufexamac are used for the treatment of subacute and chronic eczema of the skin, including atopic eczema, as well as sunburn and other minor burns,[citation needed] and itching. Suppositories containing bufexamac in combination with local anaesthetics are used against haemorrhoids.[2]
Bufexamac is thought to act by inhibiting the enzyme cyclooxygenase, which would make it a non-steroidal anti-inflammatory drug. Evidence on the mechanism of action is scarce.[3] Furthermore, bufexamac was identified as a specific inhibitor of class IIB histone deacetylases (HDAC6 and HDAC10).[4]
Bufexamac can cause severe contact dermatitis which is often hard to distinguish from the initial condition.[5] As a consequence, the European Medicines Agency recommended to withdraw the marketing approval in April 2010.[6]
