1. Local administration, precise actio

- Strong targeting: the plaster is mainly used on the skin surface, and the drug can directly act on the local area affected by the disease. For example, for joint pain, the analgesic plaster is applied to the painful joint, and the pharmaceutical ingredients can penetrate through the skin to the tissues around the joint, so as to exert the effect on the pain site accurately. Just like sending a special "treatment team" to the pain point, it can effectively relieve discomfort

- Avoid systemic reactions: Compared with oral drugs, the drugs in the patch are mostly localized, and will not be absorbed through the gastrointestinal tract and enter the systemic circulation like oral drugs. This means that the burden of drugs on organs such as the gastrointestinal tract and liver can be reduced, while also reducing the risk of side effects caused by systemic use of drugs. For example, some of the gastrointestinal irritation of drugs made into paste, will not cause gastrointestinal discomfort

II. Easy to use and carr

- Ready to Use: The use of the paste is simple and convenient. As long as it is attached to the required parts, it doesn't need to be strictly on time like taking medicine, which is more suitable for the busy rhythm of modern people's life. For example, when you feel neck pain at work, you can always take out a piece of neck and shoulder pain plaster and stick it on, which hardly affects the work at hand and can quickly relieve the pain

- Easy to carry: Stickers are usually small, lightweight and easy to carry in a purse, pocket or bag. Whether it's traveling, going to work or exercising, you can carry it with you. If you have a muscle strain, joint pain and other small conditions, you can use it immediately, just like carrying a "mobile medicine cabinet" with you

III. Sustained release, long-lasting effec

- Slow drug release: The drug in the patch is usually released slowly. The drug component continues to penetrate into the skin and tissues over a period of time, maintaining a stable drug concentration. Some patches for chronic pain, for example, can continue to work for 24 to 48 hours, just as a "long-term caregiver" is assigned to the affected area to relieve pain continuously

- Increased drug utilization: This slow-release mechanism increases drug utilization. Because the drug does not enter the body in large quantities at once, but is released gradually, the body has more time to absorb and use the drug, thereby enhancing the therapeutic effect.. t .. y .. n
