Methods: This was a prospective, right-left side intra-individual parallel 8-week study using calcipotriol 0.005% ointment applied twice daily (right side) versus tazarotene (left side) randomized to either 0.05% (group I) or 0.1% gel (group II) once daily in two groups, each of 10 patients. Efficacy was determined by the assessment of target psoriatic lesions under evaluation by using the severity scale (0-3) of erythema, scaling, and infiltration (ESI score). Evaluation was done at baseline (0 week), 4 weeks, and 8 weeks of treatment. At the end of 8 weeks, patients with more than 75% reduction in ESI score were considered to have marked improvement; 51% to 75%, moderate improvement; 26% to 50%, minimal improvement; and less than 25%, non-responders.
Conclusion: Topical calcipotriol 0.005% ointment is more effective than tazarotene 0.05% gel; however, its efficacy is comparable to tazarotene 0.1% gel in the treatment of stable plaque psoriasis.
Anthralin (Anthra-Derm) derives its origin from the herbal remedy Goa powder, which was used for refractory skin diseases in India and Brazil.6 Anthralin is presently available in ointment, cream and paste forms. Although its mechanism of action is not well defined, anthralin has been demonstrated to inhibit cell growth and restore cell differentiation. It is traditionally applied once daily at night. The initial concentration of 0.05 percent or 0.1 percent is gradually increased to no more than 3 to 5 percent.
Clinical studies have demonstrated the efficacy of both 0.05 and 0.1 percent tazarotene gel.25,26 Study results suggest that tazarotene use may lead to an extended response, providing long-term improvement and maintenance therapy.26 The gel formulation is suitable for the treatment of scalp psoriasis. Unlike calcipotriene, tazarotene can be used to treat psoriasis of the face.

Background: Topical therapies are the first line of treatment forpatients with stable plaque psoriasis affecting a limited body surface area.Though in use for more than a decade, we could not find any reports ofstudies directly comparing calcipotriol and tazarotene. Aim: To evaluate thecomparative efficacy and tolerability of calcipotriol and tazarotene in thetreatment of stable plaque psoriasis. Methods: This was a prospective,right-left side intra-individual parallel 8-week study using calcipotriol0.005% ointment applied twice daily (right side) versus tazarotene (leftside) randomized to either 0.05% (group I) or 0.1% gel (group II) once dailyin two groups, each of 10 patients. Efficacy was determined by the assessmentof target psoriatic lesions under evaluation by using the severity scale(0-3) of erythema, scaling, and infiltration (ESI score). Evaluation was doneat baseline (0 week), 4 weeks, and 8 weeks of treatment. At the end of 8weeks, patients with more than 75% reduction in ESI score were considered tohave marked improvement; 51% to 75%, moderate improvement; 26% to 50%,minimal improvement; and less than 25%, non-responders. Results: Seventeenpatients (9 in group I, 8 in group II) completed the study. In group I,reduction in ESI score was significantly more at both 4 and 8 weeks on sidestreated with calcipotriol, producing moderate-to-marked improvement (P
Twenty adult patients (12 males, 8 females) of mean age 31.7 [+ or-] 3 years (range, 18-44 years) having nearly bilateral symmetrical lesionsof stable plaque psoriasis (SPP) on limbs involving a total surface area ofnot more than 100 cm[sup] 2 were recruited. This was a prospectiveintra-individual right-left comparative pilot study of 8 weeks' durationusing calcipotriol 0.005% ointment applied twice daily versus tazarotenerandomized to either 0.05% or 0.1% gel once daily in two groups, each of 10patients. In group I, calcipotriol 0.005% ointment was applied twice dailyover lesions on the right side and tazarotene 0.05% once daily over lesionson the left side. In group II, calcipotriol 0.005% applied over lesions onthe right side was compared with 0.1% tazarotene applied over lesions on theleft side, with frequency of application remaining the same. All priormedications except antihistamines were stopped 4 weeks before the start ofthe study, and only application of an emollient (coconut oil) was permittedon both the sides. Serum calcium and phosphate estimation was done before andafter therapy. The assessment of target psoriatic lesions under evaluationand progress during treatment were done using the erythema, scaling, andinduration (ESI) score. The lesions were assessed on a grade from 0 to 3,i.e., 0 (nil), 1+ (mild), 2+ (moderate), and 3+ (severe); and amultiplication factor of 4 was applied to each grade. Thus the score rangedfrom 0 to 36.[sup] , Evaluation was done at baseline (0 week) and at4 and 8 weeks of treatment. The scores obtained were statistically comparedusing Wilcoxon test, and paired t test was used for comparing quantitativevalues. At the end of 8 weeks, patients with more than 75% reduction in ESIscore were considered to have marked improvement; 51% to 75%, moderateimprovement; 26% to 50%, minimal improvement; and less than 25%, no response.
Seventeen patients (9 in group I, 8 in group II) completed thestudy. In group I, the reduction in ESI score was significantly more at both4 and 8 weeks in the lesions treated with calcipotriol, resulting inmoderate-to-marked improvement ( P
Calcipotriol (0.005%), a vitamin D3 analog, acts in psoriasis byinhibiting keratinocyte proliferation, inducing cellular differentiation andanti-inflammatory action. In various clinical trials, it was shown to becomparable to or slightly better than class II corticosteroid ointments suchas fluocinonide 0.05%.[sup]  Compared with anthralin, it fared better interms of clinical efficacy and was preferred by patients because it does notstain as much as anthralin and is less irritating.[sup]  Combinationregimens in which patients apply both calcipotriol and superpotentcorticosteroids (weekends-only) have demonstrated superiority over theregimen with either agent alone.[sup]  Side effects reported have beenlesional and perilesional irritation, occasional hyperpigmentation, andsometimes hypercalcemia.[sup]  Studies on numerous parameters of calciummetabolism have not revealed clinically significant changes in patients whoapply less than 100 g per week of calcipotriol ointment. Hence calcipotriolis well tolerated and continues to be clinically effective with minimumadverse effects.[sup] , It is currently used as monotherapy to treatmild disease; and in moderate-to-severe plaque psoriasis, in combination withother treatment modalities.
Tazarotene is the first of a new generation of acetylenicretinoids developed for the topical treatment of psoriasis. It specificallybinds to b and g subtypes of retinoic acid receptor (RAR). Tazarotene appearsto modulate three major pathogenic factors in psoriasis: keratinocytehyperproliferation, abnormal keratinocyte differentiation, and dermal andepidermal inflammatory infiltration.[sup]  Tazarotene is available in geland cream formulation at 0.05% and 0.1% concentrations.
Lebwohl et al,[sup]  compared once-daily 0.1% and 0.05% topicaltazarotene versus twice-daily 0.05% fluocinonide in stable plaque psoriasisin 348 patients and found that tazarotene had a therapeutic effect similar tothat of fluocinonide at 12 weeks of treatment; but tazarotene demonstratedsignificantly better maintenance of therapeutic effect after cessation oftherapy. Schiener et al,[sup]  comparing the effect of combiningnarrow-band ultraviolet B irradiation with either topical tazarotene ortopical calcipotriol in 10 patients each found significant improvement ofpsoriatic lesions after 4 weeks of therapy without any therapeutic differencebetween the two regimens. Like calcipotriol, side effects of corticosteroids,including atrophy, tachyphylaxis, and rebound are avoided with the use oftazarotene. Adverse effects reported with tazarotene are mild, includingpruritus, burning/stinging, erythema, worsening of psoriasis, and irritation.They are most common during the first 1 to 2 weeks of therapy. 041b061a72
