Hi, Mahesh, I can understand your concern with treatment of psoriasis. But, you should know few things for psoriasis. Psoriasis is a chronic relapsing and autoimmune disease. There may be genetic tendency. It may be precipitated or exacerbated by few factors like dry wheather, stress,anxiety,alcohol,injury..etc. You want to know about local applications. You are trying to find out combined ointment of steroid and salicylic acid. Both the drugs might improve after applying on the lesions regularly. Steroid is anti inflammatory and salicylic acid is keratolytic. So, synergistic action is better than only applying steroid cream. In market,available ointments are clop-s,dipsalic, clopad-s, betasalic and so on..But, you must consult dermatologist for perfect and better treatment. I usually recommend cap acitretin 10 mg twice a day along with methotraxate 15 mg weekly in three devided doses 12 hourly. This may be taken for long time till good response. Blood tests may be done to monitor the treatment. Apply mild steroid cream, combined oint of steroid and salicylic acid or calcipotriol oint on the lesions. Avoid stress and worries as that might worsen psoriasis. Do not take alcohol and avoid tobacco and smoking. You may get good result after few months treatment.I hope you got my answer. Thanks.
