RESUMO
Topical antiscabietics have poor compliance. This study aimed at comparing the efficacy and safety of oral ivermectin with topical lindane in treating scabies. In this clinical trial, 248 patients from 2 to 86 years of age were divided into two groups. Oral ivermectin was given to group A in a single dose of 200 µg/kg body weight. Group B received application of lindane lotion 1% twice at one-week interval. When there was no cure in two weeks, 2nd treatment was given with either drug in the respective group. A single dose of ivermectin provided a cure rate of 58.6% at two-week follow up, which increased to 92.7% with 2 doses at the end of 4-week interval. The application of lindane lotion 1% twice at one-week interval was effective in 44.3% of patients at two-week follow up, which increased to 71.7% after repeating the treatment for another two weeks. Single dose application of oral ivermectin was as effective as twice application of lindane lotion 1% at one-week interval. Two doses of ivermectin proved superior to lindane lotion 1% after repeating the treatment at 4-week follow up.
