The new drug for hepatitis B phase II in China is propofol tenofovir, which is the upgraded version of tenofovir disoproxil fumarate, but it has both advantages as well as shortcomings. 1. Advantages: antiviral effect is faster and better, and compared with other drugs, side effects are less, drug resistance so far is zero, and the incidence of liver cancer is low, is now the most competitive oral anti-hepatitis B virus. 2. Shortcomings: Like the popular anti-hepatitis B virus oral drugs, they are nucleoside analog anti-viral drugs, which need to be taken orally for a long period of time to control the development of hepatitis B virus, and cannot cure hepatitis B, and the price is also expensive. It is recommended that the specific use of the drug should be carried out under the guidance of a doctor, to avoid blind use of adverse effects.
