AIMS: To evaluate and compare the differences in terms of efficacy, safety and relapse with Calcipotriol 0.005% (50 mcg/gm) and 6% coal tar and 3% salicylic ointment in patients with Plaque psoriasis.
SETTING and DESIGNS: Study conducted on 60 patients of plaque psoriasis, who attended the skin OPD in our hospital.
METHODS: The patients with mild to moderate plaque psoriasis were selected. 60 patients were enrolled for the study after obtaining informed consent. Subjects were asked to apply Calcipotriol 0.005% (50 mcg/gm) (Heximar Win care) twice a day on the right side plaques and on left side plaques, Petroleum jelly (Vaseline) in the morning and 6% coal tar and 3% salicylic ointment (ProtarÂ® Percos) at nighttime. PASI score was used to assess the reponse to therapy at 2nd, 4th, 6th and 8th week. After treatment subjects were observed for 6 weeks for any relapse.
STATISTICAL ANALYSIS: It was done by paired t-test and independent sample t-test.
CONCLUSIONS: The results showed that statistically significant difference was seen in the mean percentage reduction of PASI score between both the groups, at all the assessment visits, 2, 4, 6, and 8 weeks, the mean percentage reduction at 2 weeks for calcipotriol being 21Â±12.06 and for coal tar being 13.44Â±11.19 (P=0.000), at 4 weeks for calcipotriol was 40Â±16.71 and for coal tar 25Â±99 (P=0.000), at 6 weeks for calcipotriol was 53.99+-22.43 and for coal tar 41Â±21.23 (P=0.002), at 8 weeks for calcipotriol was 62.73Â±24.04 and for coal tar was 51.53Â±23.27 (P=0.11). Relapse was seen in 5/60 (8.3%) of patients on calcipotriol treated side and 9/60 (15%) of patients with coal tar treated side. Thus it can be concluded that calcipotriol cream is more efficacious when compared with coal tar and does have a quick response. It is well tolerated and acceptable cosmetically.
