Researchers in Denmark report that the protease inhibitor amprenavir (Agenerase) lowers the levels of delavirdine
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.

The citric juice appears to enhance the effects of the new drug, known as delavirdine
, reported researchers at the University of Buffalo School of Pharmacy in Buffalo, N.
In two trials of delavirdine
taken with other inhibitors of reverse transcriptase, investigators have found that they can accurately figure the odds that a patient will maintain good health.

The FDA approves the NNRTI delavirdine
mesylate inhibits cytochrome P-450, leading to a significant increase in methadone concentrations--the half-life is extended by almost 50%.
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.
(Rescriptor), indinavir (Crixivan), nelfinavir (Viracept), saquinavir (Fortovase), and efavirenz (Sustiva) may increase ergot levels resulting in ergotism (nausea, vomiting, and vasospastic ischemia).
NNRTIs include delavirdine
(Rescriptor), nevirapine (Viramune), and efavirenz (Sustiva).
Antiretroviral (ARV) drugs include protease inhibitors (PIs) such as ritonavir, indinavir, saquinavir, and nelfinavir; non-nucleoside reverse transcriptase inhibitors (NNRTIs) such as nevirapine, delavirdine
, and lovirdine; and nucleoside reverse transcriptor inhibitors (NRTIs) such as zidovudine (AZT), ddI, ddC, D4T, 3TC, and adefovir.
Serum samples for delavirdine
