Approved antiretroviral drugs
There are currently more than 20 approved antiretroviral drugs in the US and Europe (including combined formulations) and many more in the expanded access programmes and trials.
Most antiretroviral drugs have at least three names. Sometimes a drug is referred to by its research or chemical name, such as AZT. The second name is the generic name for all drugs with the same chemical structure; for example AZT is also known as zidovudine. The third name is the brand name given by the pharmaceutical company; one of the brand names for zidovudine is Retrovir. Lastly, an abbreviation of the common name might sometimes also be used, such as ZDV, which is the fourth name given to zidovudine.
The drugs listed here are those approved by the US Food and Drug Administration (FDA). This list does not contain new drugs that are currently under development and still in clinical trials, which are covered in our new AIDS drugs page. Further information should be available from your doctor.
