Purpose: Epicutaneous immunotherapy (EPIT) is being studied as a method for treating allergic rhinitis because of skin immunology, user convenience and enhanced patient compliance. However, the use of EPIT is limited because of the very low skin permeability of the allergen. In this study, the limitations of EPIT were overcome by using sophisticated delivery with microneedles.

However, for oral mucosal vaccines, delivery of the right dose of vaccine is not possible due to the water-rich environment. In this study, the buccal mucosa, which is easy to access using a microneedle array in the oral cavity, was selected as the administration site.

This paper reviews recent advancements in the development of MAPs, with a focus on their size, shapes, and materials in preclinical and clinical studies for pharmaceutics.
Area Covered: We classified MAPs for drug delivery into four types: coated, dissolving, separable, and swellable.
