Ritonavir, also known as Norvir, is a type of medicine called a protease inhibitor (PI). PIs act by blocking protease, a protein that HIV needs to make more copies of itself. Ritonavir was approved by the FDA on March 1, 1996, for use with other antiretroviral agents in the treatment of HIV infection in adults and children 2 years of age or older. Ritonavir is now approved with other anti-HIV drugs in the treatment of HIV-1 infection in children in individuals over 1 month in age. Studies have shown that ritonavir works as a booster for some other PIs. Taking ritonavir makes it possible to take a lower dose of the other PIs. This medicine does not cure or prevent HIV infection or AIDS and does not reduce the risk of passing the virus to other people.
Bristol-Myers Squibb on Friday announced that it has received FDA approval for a single 300 mg capsule formulation of its protease inhibitor Reyataz to be taken as part of combination therapy, Reuters reports.
Researchers have found, following a systematic review of all studies done on the 2003 SARS epidemic, that none of the treatments used to treat patients appear to have worked.
The SARS virus set alarm bells ringing across the world when it first appeared in 2002, but now a review of the effectiveness of the treatments used against it has found no evidence that any of them worked.
Physiologists may have found a way to decrease the risk of hardening of the arteries that accompanies the long-term use of protease inhibitors, a class of drugs that has emerged as the most effective treatment against HIV and AIDS.
There might be a simpler and less expensive method of controlling the progression of HIV, according to several preliminary studies presented last Thursday at the XVI International AIDS Conference in Toronto, the Los Angeles Times reports (Chong, Los Angeles Times, 8/18).
FDA approves Prezista (darunavir), a new drug for adults whose infection with the human immunodeficiency virus (HIV) has not responded to treatment with other antiretroviral drugs.
Tibotec Pharmaceuticals has announced that the New Drug Application (NDA) for TMC114, an investigational HIV protease inhibitor, has been accepted for priority review by the United States Food and Drug Administration (FDA).
Researchers at The Queensland Institute of Medical Research (QIMR) have found that drugs used to treat HIV Aids may also be effective against the biggest killer in the world - malaria.
Boehringer Ingelheim today announced that the U.S. Food and Drug Administration's (FDA) Antiviral Drugs Advisory Committee recommended the approval of the investigational anti-HIV drug tipranavir (11-3). Tipranavir is a non-peptidic protease inhibitor that requires boosting with low-dose ritonavir and must be used in combination with other antiretroviral agents.
Roche announced today that it has decided to discontinue the sale and distribution of Fortovase (saquinavir), as clinical demand for the drug has declined significantly due to the availability of a new formulation of Invirase (saquinavir mesylate), which increasingly has become the preferred formulation of saquinavir.
Scientists from Tibotec Pharmaceuticals Ltd. presented data on several new compounds for the treatment of HIV/AIDS at the 12th Conference on Retroviruses and Opportunistic Infections (CROI), held February 22-25 in Boston, MA, USA.
Scientists from The Queensland Institute of Medical Research (QIMR) have found that a group of HIV drugs known as protease inhibitors may also be effective for treating or preventing malaria.
The study found protease inhibitors inhibited the growth of P. falciparum, the malaria parasite that causes most disease. These findings may also expose a previously unexplored vulnerability in the parasite that could lead to a new class of anti-malarial drug.
The Company is seeking accelerated approval of tipranavir and has requested a priority, six-month review of the NDA. Priority review designation is based upon whether a drug provides a significant improvement in the treatment of a serious or life-threatening disease.
Virologists from the Katholieke Universiteit Leuven in Belgium report that chloroquine, a widely used antimalarial drug, exhibits antiviral activity against the SARS coronavirus. Chloroquine is an inexpensive and safe drug available worldwide.
Bristol-Myers Squibb has announced that Sustiva® (efavirenz) has received approval from the U.S. Food and Drug Administration to include new long-term virologic and clinical data from BMS Study 006 in its prescribing information.
The agreement resolves the two lawsuits brought by AHF against Abbott over the company's price increase for its HIV/AIDS drug, Norvir® (ritonavir).
HIV treatment regimens containing the protease inhibitor (PI) LEXIVA® (fosamprenavir calcium) dosed with ritonavir (LEXIVA/r) or lopinavir (LPV) and ritonavir (LPV/r) were effective in suppressing HIV in patients who had failed prior PI-containing regimens, according to information presented at the International AIDS Conference (IAC).
Health Canada, in association with Bristol-Myers Squibb Canada, is advising Canadians to consult with their health care professionals if they are currently being treated with the antidepressant trazodone in combination with any of the following medications: ketoconazole (an antifungal agent), ritonavir and indinavir (protease inhibitors used in the treatment of HIV), or carbamazepine (an anti-epileptic therapy).
An Italian study has provided evidence that HIV drugs called protease inhibitors may increase the risk of artery "plaques."
