Background technique [0002] A patch is a sheet-like preparation applied to the human skin, in which the drug is transdermally absorbed into the local target tissue or systemic circulatory system, including patches for local skin delivery and transdermal delivery. The patch belongs to the transdermal delivery system, and it is a drug preparation with better performance, which can keep the blood drug concentration stable within the effective concentration range of the treatment; because it avoids the first-pass effect of the drug orally through the gastrointestinal tract and liver, it is more effective than oral administration. The more stable drug administration directly into the blood stream can improve the predictability of the drug in the body; i...
