Bioavailability and therapeutic outcome of treatment with HIV-protease inhibitors depends on intestinal and hepatic transporter-enzyme interplay. Liver transport of HIV protease inhibitors (saquinavir, darunavir) was assessed in the presence of aged garlic extract, because the HIV-infected often consume garlic supplements together with prescribed t...

HIV-1 protease (PR) is a 99 amino acid protein responsible for proteolytic processing of the viral polyprotein - an essential step in the HIV-1 life cycle. Drug resistance mutations in PR that are selected during antiretroviral therapy lead to reduced efficacy of protease inhibitors (PI) including darunavir (DRV). To identify the structural mechani...

Etravirine 400 mg and darunavir/ritonavir 800/100 mg as a two-drug once-daily regimen in treatment-experienced subjects or treatment-naïve subjects with transmitted resistance was virologically efficacious and well tolerated.

HIV-1 Protease (HIV-1 PR) enzymes are essential for accurate assembly and maturation of infectious HIV retroviruses. The significant role of HIV-1 protease in viral replication has made it a potential drug target. In the recent past, phytochemical Gallic Acid (GA) derivatives have been screened for protease inhibitor activity. The present work aims...

The SLC22A1 influx transporter is expressed on the basolateral membrane of hepatocytes and is involved in the excretion of numerous cations. Inhibition of SLC22A1 by several antiretrovirals, such as the protease inhibitor darunavir, has not previously been determined. In order to better understand and predict drug-SLC22A1 interactions, a range of a...

Combination antiretroviral therapy in pregnant women with human immunodeficiency virus has dramatically decreased maternal-to-child transmission. Highly treatment-experienced pregnant patients have limited effective treatment options due to past toxicities and viral resistance. We present 8 pregnancies in 7 perinatally infected women successfully t...

This study compared the bioavailability of two candidate fixed-dose combinations (FDCs: G003 and G004) of darunavir/cobicistat 800/150 mg with that of darunavir 800 mg and ritonavir 100 mg coadministered as single agents. Short-term safety and tolerability of the FDC formulations were also assessed. This open-label trial included 36 healthy volunte...

Atazanavir/ritonavir and darunavir/ritonavir plus tenofovir/emtricitabine did not show significant differences in total cholesterol change or overall tolerability at 24 weeks. However, there was a trend towards a lower total to HDL cholesterol ratio with atazanavir/ritonavir and this effect was unrelated to bilirubin.

We found that once daily TDF/FTC and twice daily DRV/r produced trough concentrations similar to historic data in a patient who previously underwent RYGB with virologic suppression and immunologic recovery.
