迄今,已上市的药物其剂型虽然种类繁多,但绝大多数药物在到达病灶之前都会遭到体内消化系统或其它系统的分解与破坏。为达到预期的治疗效要,药(?)学家不得不加大药物剂量。可是,加入用药剂量不仅增加厂药物对人体的副作用,而且还加重了病者的药费负担。那么,有无一种剂量小、药效高的给药新途径呢?美国科研人员经过多年的研究,终于找到解决这一难题的方法,这就是“分子伞”给药新技术。
So far, although a large variety of drugs are marketed, the vast majority of drugs are degraded and destroyed by the digestive system or other systems before they reach the lesion. In order to achieve the desired therapeutic effect, drug practitioners have to increase the dosage of drugs. However, adding the dosage not only increases the side effects of the factory drugs on the human body, but also aggravates the patient’s medical expenses. So, there is a small dose, high efficacy of drug delivery new ways? US researchers after years of research and finally find a solution to this problem, which is “molecular umbrella” drug delivery technology.
