Nail Psoriasis Treatment: Insights into Current Progress and Future Trends.

Nail psoriasis is a chronic condition which causes pain and functional impairment; thus, it restricts the activities of daily living and worsens the quality of life. Different chemotherapeutic options are available for treating nail psoriasis such as systemic, intralesional, and topical therapies. However, current chemotherapy suffers from several limitations and to overcome them, new advancements are being made worldwide. Various reports have been published on current progress in the treatment of nail psoriasis such as clinical efficacy studies of novel antipsoriatic agents and novel formulation strategies for current chemotherapy. There are several novel nail formulations for the treatment of nail disorders, particularly onychomycosis, such as vesicular colloidal structure (liposomes, niosomes, transfersomes, ethosomes, etc.) and nonvesicular colloidal structures (nano-emulgel, nanocapsules, thermosensitive gel, etc.) These formulations can also prove beneficial for the treatment of nail psoriasis, and will be heavily explored in the near future. This review provides a brief introduction to the disease, its pathogenesis, and its treatment modalities. The review also throws light onto progress and future perspectives in nail psoriasis treatment.
