Short-contact anthralin therapy for psoriasis using an aqueous cream formulation

Area of Science:

• Dermatology
• Pharmacology

Background:

• Psoriasis is a chronic inflammatory skin condition.
• Anthralin is a topical treatment for psoriasis.
• Optimizing anthralin contact time is crucial for efficacy and tolerability.

Purpose of the Study:

• To evaluate the efficacy of short-contact anthralin cream therapy.
• To compare short-contact versus overnight anthralin application.
• To assess the impact of contact time on psoriasis plaque induration, staining, and irritation.

Main Methods:

• Pilot study with five patients using aqueous anthralin cream.
• Bilateral controlled study with twenty patients with chronic plaque psoriasis.
• Application of anthralin cream for 20-40 minutes, overnight, and morning short-contact (30 minutes).

Main Results:

• A 20-40 minute contact time improved psoriatic plaque induration.
• Both overnight and 30-minute short-contact anthralin treatments were equally effective.
• Short-contact anthralin application resulted in reduced staining and irritation compared to overnight.

Conclusions:

• Short-contact anthralin cream therapy is an effective treatment for psoriasis.
• Optimized contact times (20-40 minutes) can enhance treatment outcomes.
• Short-contact anthralin offers a favorable balance of efficacy and tolerability.
