ABSTRACT
Background: Acne vulgaris is a dermatological disorder characterised by formation of comedones and inflammatory lesions. Acne is one of the most common reason for visiting a dermatologist in early adulthood. The current line of management for mild to moderate acne is topical medications with antimicrobials and retinoids. The present study assessed the effectiveness and safety of topical combination therapy for mild to moderate acne vulgaris.Methods: An observational, prospective and comparative study conducted on newly diagnosed acne vulgaris patients who were treated with topical combination therapy. Changes in the total, inflammatory and non-inflammatory lesion counts, investigator global assessment (IGA) and dermatology life quality index (DLQI) scales were recorded to check effectiveness. Treatment emergent adverse events were recorded in suspected ADR reporting form for safety assessment.Results: Participants (n=97) were treated with three topical combination treatments either clindamycin-benzoyl peroxide (group-A), clindamycin-adapalene (group-B) or benzoyl peroxide-adapalene (group C). Majority of participants (42.3%) were treated with clindamycin-benzoyl peroxide group. Reduction from baseline of total, inflammatory and non-inflammatory lesion counts were highly significant within group comparison (p<0.001), but between group differences were not significant. Significant improvement in DLQI and IGA scores were noted in all three groups, but between group comparison showed no significant differences. All three groups were safe and well tolerated and equally improve participant’s quality of life.Conclusions: all three topical combination drugs for mild acne vulgaris had similar effectiveness in terms of reduction in acne lesions with similar safety profile.
