AIDS: Physicians now have 14 different approved anti-HIV drugs to treat the disease, and the possible combinations can be overwhelming to both patients and doctors. In addition to these drugs, other agents, such as hydroxyurea and IL-2, may be added to the treatment regimen. Several tables group the approved drugs by drug class and include the generic name, brand name, common abbreviation, and standard dose for each drug. A table illustrates common drug interactions, and another specifies overlapping toxicities associated with HIV-related medications. The issues of drug metabolism, combination therapies, pill burden, and storage are also addressed.
