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 Company and AstraZeneca today announced results up to 76-weeks from a Phase 3 study of ONGLYZA(TM) (saxagliptin) as initial combination therapy with metformin, which produced long-term glycemic improvement (as measured by glycosylated hemoglobin level (HbA1c)) in treatment-naive adults with type 2 diabetes mellitus inadequately controlled on diet and exercise compared to treatment with an investigational 10 mg dose of saxagliptin or metformin alone.
Merck today announced plans to initiate a Phase II investigational proof-of-concept clinical study to evaluate its oral antifungal agent posaconazole for the treatment of chronic Chagas disease. Chagas disease results from infection with the parasite Trypanosoma cruzi that is spread by biting insects. The disease is estimated to affect approximately eight million people in Latin America, of whom approximately 30-40 percent will develop serious cardiac disease, digestive disease, or both as a result of this infection.
Merck today announced that the U.S. Food and Drug Administration (FDA) has approved DULERA® (mometasone furoate and formoterol fumarate dihydrate) Inhalation Aerosol, a new fixed-dose combination asthma treatment for patients 12 years of age and older. DULERA is not indicated for the relief of acute bronchospasm. DULERA combines an inhaled corticosteroid (mometasone furoate) with a long-acting beta2-agonist (formoterol fumarate).
Bristol-Myers Squibb Company and Otsuka Pharmaceutical Co., Ltd. today announced four-year follow-up results from a Phase 3 randomized, open-label, dose-optimization study of SPRYCEL® (dasatinib) in chronic-phase chronic myeloid leukemia (CML-CP) patients resistant or intolerant to Gleevec®* (imatinib mesylate). At four years, for all patients administered SPRYCEL 100 mg once daily, overall survival was 82% (95% CI: 76%-88%) and progression-free survival was 66% (95% CI: 57%-74%).
Preliminary findings from a unique study with sunitinib suggest that it might be possible to tweak the dosage of chemotherapy drugs used to treat HIV-positive cancer patients to achieve therapeutic benefit. Given the type of drug cocktail patients use to treat their HIV, much more or considerably less chemotherapy may be warranted, say the researchers, part of the NCI-supported AIDS Malignancy Consortium (AMC). The trial design is being presented at the 2010 annual meeting of the American Society of Clinical Oncology (ASCO).
Merck announced today results from a new non-inferiority trial of an antiemetic regimen containing fosaprepitant dimeglumine administered as a single intravenous (IV) 150-mg dose in combination with a 5-HT3 antagonist and dexamethasone compared with a three-day regimen of aprepitant with a 5-HT3 antagonist and dexamethasone for the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients receiving a first cycle of cisplatin-based chemotherapy.
Sanofi-aventis announced today the initiation of a multinational, randomized double-blind Phase IIIb trial, PALLAS, to assess the potential clinical benefit of Multaq(R) (dronedarone) in over 10, 000 patients with permanent atrial fibrillation (AF) to reduce major adverse cardiovascular events. The announcement was made during Heart Rhythm 2010, the Heart Rhythm Society's 31st Annual Scientific Sessions.
