Darunavir (CAS 206361-99-1) is a new kind of non peptide anti retroviral protease inhibitors in AIDS therapy. It is first developed by the Johnson pharmaceutical Iceland branch, Tibotec. It is of the highest bioavailability in the 6 protease inhibitors (saquinavir, ritonavirvir, indinavir, naphthalene nelfinavir, amprenavir and ABT378/r). It acts by blocking the formation of new and mature virus particles from the surface of the infected host cells and inhibiting the virus’s protease. When the product is used for a long time, it usually can reduce the HIV virus vector in blood, increase the count of CD4 cells, reduce the chance of HIV infection, improve the quality of life and prolong life. It is suitable for adults who are infected with the HIV virus but have no effect on the use of existing antiretroviral drugs. The drug must be combined with the use of low doses of ritonavir or other antiretroviral agents, in order to improve the efficacy.
