ritonavir-boosted atazanavir side effects

* Boceprevir reduced average trough concentrations of ritonavir-boosted atazanavir (Reyataz), lopinavir (Kaletra), and darunavir (Prezista) by 49%, 43% and 59%, respectively. * On average, reductions of 25% to 36% were seen in peak concentration of the three drugs, when given with boceprevir, along with declines of 34% to 44% in exposure (area under the curve).

A case series describes three patients who experienced excessive opiate effects of buprenorphine during concomitant antiretroviral therapy with atazanavir, ritonavir, and various nucleoside reverse transcriptase inhibitors. Two of the patients had been on their antiretroviral regimen for several months and reported doped-up feeling, dizziness, and feeling high following initiation of buprenorphine 8 mg/day. The dosage was reduced to 8 mg every other day.

1) 19 treatment-naive patients received 250 mg of ABT-450, an NS3 HCV PI, boosted with ritonavir 100 mg daily, 400 mg of ABT-333, a non-nucleoside HCV polymerase inhibitor, and RBV 1,000 to 1,200 mg; 2) 14 treatment-naive patients received the same drug regimen with a lower ritonavir-boosted ABT-450 dose of 150 mg daily; 3) 17 HCV patients who were prior non-responders received the same low ABT-450 dose regimen as the second group. Treatment duration in all arms was 12 weeks.

However, after 2013, three-drug regimen consisting of a nucleoside reverse-transcriptase inhibitor (NTRI), (tenofovir plus emtricitabine), along with a third drug, either an integrase strand transfer inhibitor, raltegravir or a boosted protease inhibitor, darunavir/ritonavir is recommended for PEP. Ideally, NTRI is an important component of the regimen because if HIV infects a cell, it first attaches to and fuses with the host cell.

AbbVie, which has four more Phase III trials underway, is also testing its drugs without ribavirin - a medicine that can cause anemia and other side effects. But other companies are shooting for combination regimens that involve just one or two pills a day. "Gilead will have a convenience advantage," Arfaei said. "However, we do not believe convenience is as important for an 8-12 week treatment regimen that produces a cure compared with for example chronic HIV treatment.

The regimen did not include interferon, a standard component of hepatitis C therapy that causes flu-like side effects that can last for months. The study included 77 patients who hadn’t been treated before and 41 patients who were not helped by other treatments. Sounds good for those of us that will start treatment soon. I want to reverse my liver damage while I still have the opportunity even though I'm 4-4 -- still compensated still have hope.

January 2013 Detailed Clinical Trial Description A study to evaluate the safety and effect of experimental drugs ABT-450, ABT-267, ABT-333, ritonavir, and Ribavirin in people with HCV. The study will test the safety and effects of combinations of these drugs in treatments up to 24 weeks.

EASL Brief Preview, liver conference next week in Barcelona: interferon-free therapies http://www.natap.org/2012/HCV/041112_01.htm (below is actual text, but I have broken it into segments for emphasis and easier understanding - Willy) from Jules: The annual European liver meeting EASL, European Association for the Study of the Liver, starts April 18 where there will be new data on numerous oral HCV drugs in various stages of development and on new interferon-free oral HCV drug therapies.

My father had severe acne until he took accutane for 3 months at a high dose without recieving any negative side effects, which cleared up 90 percent of the acne. My mother didnt have acne. I am ready to go on accutane, but the thing is that I do submission wrestling. If the accutane permanently damaged my joints or hindered my athletic performance I would be devastated. My question is, how long should I take accutane and at what dose?

For patients taking darunavir plus ritonavir, fosamprenavir, forsamprenavir plus ritonavir, or saquinavir plus ritonavir, the atorvastatin dose should be limited to 20 mg daily. In patients taking nelfinavir, daily atorvastatin should not exceed 40 mg. Rosuvastatin should be limited to 10 mg daily in patients taking altazanavir with or without ritonavir or lopinavir plus ritonavir.

The all-oral treatment regimen consisted of ABT-450 (a daily NS3/4A protease inhibitor) boosted with ritonavir (ABT-450/r), ABT-267 (a daily NS5A inhibitor), and ABT-333 (a twice-daily nonnucleoside polymerase inhibitor) with or without ribavirin.

A Study to Evaluate the Safety and Effect of ABT-450, Ritonavir and ABT-267 (ABT-450/r/ABT-267) and ABT-333 Coadministered With Ribavirin (RBV) in Hepatitis C Virus (HCV) Genotype 1-infected Adults With Compensated Cirrhosis. (TURQUOISE-II) The purpose of this study is to evaluate the safety and effect of ABT-450, ritonavir and ABT-267 (ABT-450/r/ABT-267) and ABT-333 coadministered with ribavirin (RBV) in HCV genotype 1-infected adults with compensated cirrhosis.

What are any steps I can take to reduce the side-effects of PEP and to ease my struggle with the side effects? I will be meeting a specialist in a week's time to discuss my concerns further but until then what can I do to make PEP easier on me? Thanks again.
