There are several topical treatment for Pityriasis Versicolor including ketoconazole and selenium sulfide. Ketoconazole is a broad spectrum anti-fungal drug from imidazole group that has been reported to be effective in PV. The study aimed to reveal the mycological efficacy, safety, recurrence and cost-effectiveness of selenium sulfide 1.8% shampoo (SeS2) and ketoconazole 2% shampoo in the treatment of pityriasis versicolor. A double blind randomized controlled trial was performed in patients with PV during September-December 2018. Patients who involved in this study were allocated to SeS2 or ketoconazole 2% based on block randomization. Physical examinations, scale provocation test, Wood lamp and potassium hydroxide (KOH) examination were conducted to evaluate the treatment response and side effects on 7th - 14th day. Intention to treat analysis was performed in this study. cost-effectiveness was analyzed by Incremental Cost-Effectiveness Ratio (ICER).

cost-effectiveness
Cost calculations include administrative fees (registration and consultation of doctors), laboratory examinations, medical expenses and compensation for side effects adjusted for the duration of therapy. The results of the calculation of costs obtained are then linked to the negative outcome difference (KOH is still positive) or the value of absolute risk reduction (ARR) on day 14. So that cost efficacy is seen from Incremental Cost-Effectiveness Ratio
Time frame: two weeks
recurrence
if the KOH test 20% give a positive result again
Time frame: 1 month
