Recent Advancement in Topical Nanocarriers for the Treatment of Psoriasis

Psoriasis is a life-threatening autoimmune inflammatory skin disease, triggered by T lymphocyte. Recently, the drugs most commonly used for the treatment of psoriasis include methotrexate (MTX), cyclosporine (CsA), acitretin, dexamethasone, and salicylic acid. However, conventional formulations due to poor absorptive capacity, inconsistent drug release characteristics, poor capability of selective targeting, poor retention of drug molecules in target tissue, and unintended skin reactions restrict the clinical efficacy of drugs. Advances in topical nanocarriers allow the development of prominent drug delivery platforms can be employed to address the critical issues associated with conventional formulations. Advances in nanocarriers design, nano-dimensional configuration, and surface functionalization allow formulation scientists to develop formulations for a more effective treatment of psoriasis. Moreover, interventions in the size distribution, shape, agglomeration/aggregation potential, and surface chemistry are the significant aspects need to be critically evaluated for better therapeutic results. This review attempted to explore the opportunities and challenges of current revelations in the nano carrier-based topical drug delivery approach used for the treatment of psoriasis.

Automated summary

Psoriasis, an autoimmune inflammatory skin disease, is treated with drugs like MTX, CsA, acitretin, dexamethasone, and salicylic acid. However, conventional formulations have limitations, prompting the development of advanced topical nanocarriers to enhance drug delivery efficacy and address critical issues. Nanocarriers design, nano-dimensional configuration, and surface functionalization play key roles in creating effective formulations for psoriasis treatment.
