The drugs used to treat AIDS and tuberculosis are different, not the same. First of all, for the treatment of AIDS, there are more than 30 commonly used anti-retroviral agents in six categories, which are categorized as nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors, protease inhibitors, fusion inhibitors, integrase inhibitors and CCR5 inhibitors. These drugs can maximize the inhibition of viral replication and rebuild or maintain immune function. In contrast, TB chemotherapeutic drugs mainly include first-line (class) antituberculosis drugs such as streptomycin, isoniazid, rifampicin, pyrazinamide, and ethambutol. Thus, the main mechanism of drugs for HIV is antiviral, while the main mechanism of drugs for TB is antimicrobial, and the difference between the two is relatively large.
