Overview
The mainstay of therapy for psoriasis is topical agents applied directly onto the lesions. Topical agents include corticosteroids, vitamin D analogues, tar, anthralin, tazarotene, calcineurin inhibitors and aloe vera extracts. Systemic therapy may also be used which includes immunosupressants to counter act the disease process.
Medical Therapy
Therapies are administered according to disease severity and assessed by the Psoriasis Area and Severity Index (PASI, ranging from 0 to 72), which takes into account appearance and extension of the lesions. Interventions in medical therapy for psoriasis comprise:
- Topical therapy
- Phototherapy
- Systemic therapy (immunosuppressive agents and biological therapy)
Topical therapy
- Medicated creams and ointments applied directly to psoriatic lesions can help decrease inflammation, remove built-up scale, reduce skin turn over, and clear affected skin of plaques.[1]
- Approved drugs that can be used as topical therapy for acute management of psoriasis include:[2][3][4][5][6]
- Corticosteroids
- Vitamin D analogues (calcipotriol)
- Tar
- Dithranol (anthralin)
- Tazarotene (a retinoid)
- Calcineurin inhibitors (Tacrolimus and primecrolimus- used specially for flexural or facial psoriasis)
- Aloe vera extract 0.5% hydrophilic cream
- Anti-IL-8 monoclonal antibody cream
- Betamethasone 17-valerate 21-acetate plus tretinoin plus salicylic acid
- Fish oil plus occlussion
- Combination of nicotinamide and calcipotriene
- Combined treatment with vitamin D/corticosteroid on either the body or the scalp has significantly better outcomes than vitamin D alone.[7]
- The disadvantages of topical agents are that they can often irritate normal skin, can be time consuming and awkward to apply, cannot be used for long periods, can stain clothing, or can have a strong odor. As a result, it is sometimes difficult for people to maintain the regular application of these medications.
- Abrupt withdrawal of some topical agents, particularly corticosteroids, can cause an aggressive recurrence of the condition.
- Some topical agents are used in conjunction with other therapies, especially phototherapy.
Phototherapy
- It has long been recognized that daily, short, non-burning exposure to sunlight helped to clear or improve psoriasis.[8]
- Niels Finsen was the first physician to investigate the therapeutic effects of sunlight scientifically and to use sunlight in clinical practice. This became known as phototherapy.
- The narrow band part of the UVB spectrum (311 to 312 nm) is most helpful for psoriasis. Exposure to UVB several times per week over several weeks can help people attain a remission from psoriasis.
- Ultraviolet light treatment is frequently combined with topical (coal tar, calcipotriol) or systemic treatment (retinoids) as there is a synergy in their combination.
- The Ingram regime involves UVB and the application of anthralin paste.
- The Goeckerman regime combines coal tar ointment with UVB.
