Abstract
Silver Sulphadiazine (SSD) is an effective antibacterial agent considered as the gold standard for burn wound treatment. The present study aimed to investigate EO-based organogel (SSD-EOOG) as an effective carrier system for SSD delivery in burn wound management employing Quality by Design (QbD) paradigm. The organogel-based formulations were prepared employing QbD-oriented approach and further evaluated for in vivo efficacy and stability. The developed formulations were characterized for particle size, drug content, morphology, in vitro drug release, skin safety studies, ex vivo permeation, skin retention, textural analysis and pharmacodynamic studies in murine burn wound model. I-optimal mixture design was employed for optimization and evaluating different critical quality attributes (CQAs). The optimized formulation exhibited particle size of 256.5nm with enhanced permeation (72.33±1.73%) and retention (541.20±22.16µg/cm2) across skin barrier as compared to SSD-MKT. The pharmacodynamic results proved superior therapeutic efficacy of SSD-EOOG in topical burn wounds inflicted with MRSA bacterium. The results indicated wound contraction rate (78.23±5.65%) and faster re-epithelialization in SSD-EOOG treated group. The present study concluded that egg oil based organogel promoted therapeutic efficacy of SSD for burn wound treatment.
