Among the topical plaster patches products, natural rubber substrates are mainly used in China. As a new material, hydrogel substrates become popular in Japan, China, South Korea and other countries from the past one to two years.
|Product Name||traditional plaster patches||hydrogel plaster patches|
|Advantage||Strong cohesion, good elasticity, strong initial and lasting viscosity||Very hypoallergenic, non-irritating to the skin, stable drug release, can be uniformly coordinated with various drugs, no contraindications for compounding, and low cytotoxicity.|
|Disadvantage||Easily allergic, expensive, non-hydrophilic, poor water resistance, poor air permeability, high cytotoxicity, poor drug release ability, unstable release, easy to burst release||The initial adhesion, holding adhesion and material strength are not as good as traditional plasters|
In summary, as a new type of polymer material, hydrogel is increasingly used in the fields of medicine and bioengineering materials due to its unique characteristics.
