Hello and welcome to healthcaremagic Plaque Psoriasis is characterized by the presence of well defined, thick scaly plaques mainly involving the scalp, and extensor surfaces like elbow, knee, lower back etc Unlike extensive psoriatic disease for which both oral and topical treatment is required, for limited disease topical treatment alone is effective. Specific treatment options for psoriatic plaques are topical steroid with or without salicylic acid, topical Vitamin D analogues like calcipotriol, calcipotriene etc. These are available in ointment form for plaques involving the body and in lotion form for scalp psoriasis. Besides specific remedies for psoriasis, moisturizers form an important part in the management of psoriasis because of the thick scaly nature of the plaques. Moisturizers enhance the penetration of topical active ingredients as well as prevents or delays side effects like skin atrophy etc. You have been on emoderm(a moisturizer), salytar solution(coal tar+salicylic acid shampoo) and propysalic nf 6ointment (steroid+salicylic acid ointment). I find it absolutely right and therefore, I would suggest that you continue with this prescription as advised by your doctor and follow up with your doctor every 2-4 weeks. Hope this helps Regards
