Clinical Indications for Thalidomide

Use :

Erythema nodosum leprosum: Acute treatment of cutaneous manifestations of moderate to severe erythema nodosum leprosum; maintenance treatment for prevention and suppression of cutaneous manifestations of erythema nodosum leprosum recurrence

Limitation of use: Thalidomide is not indicated as monotherapy for erythema nodosum leprosum treatment in the presence of moderate to severe neuritis.

Multiple myeloma: Treatment of newly diagnosed multiple myeloma (in combination with dexamethasone)

Mechanism of Action :

Thalidomide exhibits immunomodulatory and antiangiogenic characteristics; immunologic effects may vary based on conditions. Thalidomide may suppress excessive tumor necrosis factor-alpha production in patients with erythema nodosum leprosum, yet may increase plasma tumor necrosis factor-alpha levels in HIV-positive patients. In multiple myeloma, thalidomide is associated with an increase in natural killer cells and increased levels of interleukin-2 and interferon gamma. Other proposed mechanisms of action include suppression of angiogenesis, prevention of free-radical-mediated DNA damage, increased cell mediated cytotoxic effects, and altered expression of cellular adhesion molecules.

Fun fact : Thalidomide causes congenital defects called phocomelia.
