Betamethasone valerate in foam vehicle is effective with both daily and twice a day dosing: a single-blind, open-label study in the treatment of scalp psoriasis.

Abstract

BACKGROUND:

Psoriasis is a chronic relapsing skin disorder that affects about 2% of the U.S. population and involves the scalp approximately 50% of the time. Topical corticosteroids, including betamethasone valerate, have been used effectively in the treatment of corticosteroid-responsive dermatoses of the skin and scalp. Betamethasone valerate (BMV) in foam vehicle (Luxiq) is designed to improve patient compliance with topical therapy. Superior efficacy over a BMV lotion preparation has been demonstrated with twice-daily use. Even greater compliance would be expected if the drug is effective with once-daily application.

PURPOSE:

To compare the efficacy of the betamethasone valerate foam (Luxiq) in the treatment of scalp psoriasis following once-daily versus twice-daily dosing.

METHODS:

Seventy-nine patients with moderate to severe scalp psoriasis from seven centers were enrolled and treated with BMV foam either once a day or twice a day for four weeks. The physician-grader was blinded to the treatment regimen, and the subjects were randomly assigned to either once-daily or twice-daily dosing in a 1:1 ratio.

RESULTS:

The signs of psoriasis (plaque thickness, scaling, and erythema) were assessed before and after treatment. The investigator's and the patients' global assessments were also evaluated. The composite score improved from 7.7 +/- 2.1 to 3.0 +/- 2.2 with twice-a-day use and from 8.1 +/- 2.2 to 3.9 +/- 2.8 with once-daily use (p > 0.05 for the difference between groups).

DISCUSSION:

BMV foam is effective for scalp psoriasis with both once-a-day and twice-a-day use. This feature of the BMV foam is encouraging for expected improvement in clinical use.
