Interventional
Description of intervention(s) / exposure
Patients will be divided into two groups. Group A will receive low dose isotretinoin 20 mg oral capsule daily and Group B will receive pulsed dose of 1 mg/kg/day oral capsule for 1 week in the whole month( 4 weeks). Patients assigned to either groups using the sequential method. Patients will receive treatment for 6 months. All the patients will be provided with the same brand of medicine to minimize brand bias. Primary endpoint will be photographic score at the end of 6 months from baseline. Standardized digital photographs of the acne affected area will be taken every month with the patient in a similar position to ensure consistency of photography. Treatment response will be evaluated on a standardized 4-point rating scale calculated at the end of 6 months following completion of treatment , as indicated with help of ( annexure C ) - Global Acne Grading System.
0 = completely cleared (100% improved from baseline Acne severity index),
1 = marked improvement ( > 75% improved from baseline Acne severity index),
2 = moderate improvement ( 50–75% improved from baseline Acne severity index),
3 = mild improvement ( 25-50% improved from baseline Acne severity index ),
4 = insignificant improvement ( <25% improved from baseline Acne severity index) .. Safety evaluations will be done on monthly visits by asking patients about any adverse effects related to medication. Baseline investigations using CBC, LFT, lipid profile and urine pregnancy test ( females of child bearing age ) will be done before starting treatment and follow up investigations at end of first, third and sixth month of treatment. Female participants will get treatment only after their next menstrual period to ensure that they are not pregnant at time of treatment initiation. The participants were also followed up for 8 months after completion of treatment to look for any relapse.

Statistical methods / analysis
A total of 90 patients will be divided into Group A and B by sequential method. The sample size has been calculated on WHO sample size calculator.
Data will be analyzed using SPSS version 26.0. Descriptive statistics will be calculated as mean ±1 standard deviation for age and duration of lesions. Frequency and percentages will be calculated for qualitative variables like side effects and patients’ satisfaction. Effect modifiers will be controlled through stratification and post-stratification Chi-square test and independent sample t-test will be applied for comparing age and duration of lesions taking p-value less than 0.05 as significant. Chi-square test will be applied to compare efficacy of both drugs.
