* Nevirapine is similar to delavirdine, causing a decrease of about 50% in methadone area-under-the-curve concentrations.
The relative retention factors (k' values) for several other drugs that are commonly used as either antiviral drugs (DMP 266, delavirdine, and nucleosides) or drugs that are used to prevent or treat opportunistic infections (azole antifungals, macrolides, atovaquone, rifabutin, rifampin, trimethoprim, and sulfamethoxazole) are listed in Table 5.

For example, a study of the drug delavirdine, in which 19 percent of the participants were women, showed a longer retention time in women s bodies than in men s (Women Alive, 1997).
Some of those ongoing trials test drugs, such as AZT (zidovudine), didanosine (ddI), and delavirdine, that target reverse transcriptase, the enzyme HIV uses to integrate its genetic material into host cells.

Some patients may be sensitive to non-nucleoside reverse transcriptase inhibitors such as nevirapine, delavirdine, and efavirenz.
This is a very active antiretroviral of the NNRTI class (non-nucleoside reverse transcriptase inhibitor -- the same class as efavirenz, nevirapine, and delavirdine, the three NNRTI drugs currently approved in the U.S.).
