Outline
Styrene-isoprene-styrene block copolymer pressure sensitive adhesive (SIS-PSA) is an ideal commercial adhesive with unique environmental attributes and high processability. As a key excipient for patches, SIS-PSA has a significant impact on the key properties such as drug release and adhesion. Since the performance of SIS-PSA is determined by a combination of different components, a thorough understanding of these components is essential for patch formulation design. This article discusses the impact of each component in SIS-PSA on the key performance of patches, summarizes the composition and application of marketed SIS-PSA patches, and focuses on patch formulation design oriented towards clinical needs, aiming to provide a reference for the research and development of SIS-PSA patches.
