WEDNESDAY, Feb. 4, 2009 (HealthDay News) -- Galderma Laboratories' Vectical (calcitriol) ointment has been approved by the U.S. Food and Drug Administration to treat mild-to-moderate plaque psoriasis in adults, the company said.
Approval was based on two eight-week studies involving more than 800 people. Improvement was first observed at week two, Galderma said in a news release.
The most frequently reported side effects included skin discomfort and high amounts of calcium in the urine.
Psoriasis is a chronic skin disorder characterized by thick, dry scaly patches. Up to 3 percent of the U.S. population has the disorder, accounting for millions of hours of lost productivity each year, the company said.
