Nanoemulgels: A new approach for the treatment of skin-related disorders

Skin-related disorders like psoriasis, dermatitis, acne, and wounds affect a major sector of the global population. Conventional treatment modalities exhibit limitations encompassing systemic adverse effects, suboptimal skin permeability, and variable drug release kinetics. Nanoemulsion-based hydrogels, also known as nanoemulgels, have emerged as a promising approach for topical and transdermal drug delivery, particularly in treating skin disorders. These have the advantages of nanoemulsions and hydrogels, offering enhanced therapeutic efficacy. Further, nanoemulgels can facilitate controlled and sustained drug delivery, reducing the frequency of application and improving patient compliance. These nanoemulgels hold significant prospects in topical and transdermal applications, particularly in delivering therapeutic cargo in diseases such as mycoses, atopic dermatitis, and psoriasis. This review will outline the functions of nanoemulgels, the building blocks of nanoemulgels, their formulation techniques, evaluation parameters, and their pharmacological applications. Further, an overview of the current state of research in the field of nanoemulgels, future directions, and challenges associated with nanoemulgels was also provided.
