近年来,表面活性剂在制药学中获得了广泛的应用,利用它们可配制成稳定的药剂,象软膏、乳剂、混悬剂、洗剂、乳膏等等。表面活性剂能保证被应用的药物分布均匀。在许多场合它们具有润湿物质、降低皮肤或粘膜和药物剂型之间的表面张力的作用,这即使得药物易于通过组织进行扩散。 In recent years, surfactants have gained a wide range of applications in pharmaceutics and can be formulated into stable pharmaceuticals such as ointments, creams, suspensions, lotions, creams and the like. Surfactants ensure that the drug being applied is distributed evenly. In many cases they have a moisturizing substance which reduces the surface tension between the skin or the mucosa and the pharmaceutical dosage form which makes it easier for the drug to diffuse through the tissue.
