The antiretroviral potency of emtricitabine is approximately 3-fold higher compared to lamivudine in dual human immunodeficiency virus type 1 infection/competition experiments in vitro
چکیده انگلیسی

The increasing number of antiretroviral drugs leads to mounting possibilities of combinations for the antiretroviral therapy (ART) of HIV-1 infected patients. Thus, it is of interest to determine the most potent combination of antiretroviral drugs for the first ART to delay the development of drug resistance. We have investigated the differences in the inhibitory potencies of the nucleoside reverse transcriptase inhibitors (NRTI) lamivudine (3TC) and emtricitabine (FTC) using an in vitro model based on simultaneous infection of T cells with drug-sensitive and drug-resistant viruses. Changes of frequencies in these virus populations have been measured by allele-specific real-time PCR allowing simultaneous quantification of different HIV-1 variants in the same sample. We show that the suppression of drug-sensitive viruses is significantly enhanced by FTC compared to 3TC. Mathematical modeling of the distinct rates of suppression of drug-sensitive viruses revealed an approximately 3-fold higher antiretroviral potency for FTC compared to 3TC.
