Each ml. of Oxsoralen Lotion contains 10 mg. methoxsalen in an inert vehicle containing alcohol (71% v/v), propylene glycol, acetone, and purified water. Methoxsalen is a naturally occurring substance found in the seeds of the Ammi majus (Umbelliferae) plant and in the roots of Heracleum Candicans. It belongs to a group of compounds known as psoralens or furocou-marins.
OXSORALEN (Methoxsalen TOPICAL) is indicated for the following:
As a topical repigmenting agent in vitiligo in conjunction with controlled doses of ultraviolet A (320-400 nm) or sunlight.

Randomized, double-blind comparison of 1 mg/L versus 5 mg/L methoxsalen bath-PUVA therapy for chronic plaque-type psoriasis. [2006.10]
BACKGROUND: Bath-psoralen plus ultraviolet A (PUVA) radiation therapy is increasingly replacing oral PUVA because of its superior short- and long-term safety profile. Several investigations in recent years have led to a refinement of the bath-PUVA protocol; however, the optimal therapeutic concentration of methoxsalen in the bath water has as yet not been delineated. OBJECTIVES: The therapeutic efficacy and tolerability of bath-PUVA by using two different dilutions of methoxsalen (1 mg/L vs 5 mg/L or 0.0001% vs 0.0005%) were compared in 46 patients with chronic plaque-type psoriasis in a prospective, randomized, double-blind study... CONCLUSIONS: Our data indicate that in bath-PUVA treatment the use of a high (5 mg/L) methoxsalen concentration is substantially more effective in clearing chronic plaque-type psoriasis than a low (1 mg/L) concentration.
Drug-drug interaction after single oral doses of the furanocoumarin methoxsalen and cyclosporine. [2006.07]
Furanocoumarins increase the bioavailability of drugs that are CYP3A4 substrates. A possible interaction of methoxsalen with cyclosporine was evaluated in 12 healthy volunteers following oral administration of 40 mg methoxsalen, 200 mg cyclosporine, or a combination of both in a randomized crossover study...
Clinical Trials Related to Oxsoralen (Methoxsalen Topical)
Safety and Efficacy of Extracorporeal Photoimmune Therapy With UVADEX for the Treatment of Crohn's Disease [Completed]
his study will explore the safety and activity of ECP treatment with UVADEX in inducing a
clinical response (i. e., a CDAI decrease greater than or equal to 100 from baseline and/or a
CDAI < 150) over a 12-week period in moderately active Crohn's disease (CDAI greater than or
equal to 220 to < 450) patients who are refractory or intolerant to immunosuppressants
and/or anti-TNF agents. This study will also assess response to continued treatment during
a 12-week Extension Period in patients who have a clinical response at Week 12 of the
Treatment Period and elect to participate in the Extension Period.
