The World Health Organization's ATC classification organizes medical drugs based on therapeutic properties, chemical composition, and anatomy. It helps make essential medicines readily available globally and is widely used in the pharmaceutical industry.

| 3 | J05A | Direct acting antivirals | |
| 4 | J05AR | Antivirals for treatment of HIV infections, combinations | |

| Active Ingredient | Description | |

| Zidovudine, Lamivudine and Abacavir |
Abacavir, lamivudine and zidovudine are all NRTIs, and are potent selective inhibitors of HIV-1 and HIV-2.All three medicinal products are metabolised sequentially by intracellular kinases to the respective 5′-triphosphate (TP). Lamivudine-TP, carbovir-TP (the active triphosphate form of abacavir) and zidovudine-TP are substrates for and competitive inhibitors of HIV reverse transcriptase (RT). However, their main antiviral activity is through incorporation of the monophosphate form into the viral DNA chain, resulting in chain termination. Abacavir, lamivudine and zidovudine triphosphates show significantly less affinity for host cell DNA polymerases. |
