Abbott Receives U.S. FDA Approval for Heat-Stable Norvir(R) (ritonavir) TabletsABBOTT PARK, Ill., Feb. 11 (Healthcare Sales & Marketing Network) -- Abbott (NYSE: ABT) announced today that the U.S. Food and Drug Administration (FDA) has granted approval of a new tablet formulation of the company's antiretroviral medication Norvir ® (ritonavir). The new Norvir tablets can be stored at room temperature and do not require refrigeration, making it more convenient for patients. The Norvir tablets and the Norvir soft-gelatin capsules both contain 100 mg of ritonavir. While the rate of drug absorbed is different, there is no requirement for dosage change. Norvir is used in combination with other antiretroviral medications to treat HIV. All forms of Norvir, including the soft-gel capsule and liquid form, remain available in the United States.
"Norvir has been a critical component of HIV treatment for many patients. The innovation behind the development of the Norvir tablet is the direct result of years of effort by Abbott scientists to address the needs of people living with HIV," said Scott Brun, M.D., divisional vice president, infectious disease development, Global Pharmaceutical Research and Development, Abbott. "Abbott has been dedicated to finding new and more convenient ways for patients to manage their HIV through the development of novel diagnostics testing methods and medications for more than 20 years."
Abbott scientists evaluated several candidate formulations before developing the final Norvir tablet formulation. The Norvir tablet was developed using Abbott's Meltrex® technology, a proprietary melt-extrusion process, making it more heat-stable. This is the same technology used to develop Abbott's Kaletra® (lopinavir/ritonavir) tablet, which combines lopinavir and ritonavir.
"Approximately one-third of all HIV-positive patients in treatment use Norvir in combination with other antiretroviral medicines. The heat-stable tablet formulation may allow these patients greater flexibility to store and carry their medication with them," said Renslow Sherer, M.D., professor of medicine, section of infectious diseases and global health and director, International HIV Training Center, University of Chicago Hospitals. "For patients who may not have access to refrigeration, this new formulation is also important."
Important Information About Norvir
Do not take Norvir with certain medicines, as these can cause serious or life-threatening problems such as irregular heartbeat, breathing difficulties, or excessive sleepiness. Do not take Norvir if you have had a serious allergic reaction to any of its ingredients. Some patients taking Norvir may develop liver and pancreas problems, which can cause death. Patients may develop large increases in triglycerides and cholesterol, diabetes, high blood sugar, changes in body fat, increased bleeding in people with hemophilia, allergic reactions, and/or changes in heart rhythm. You may develop signs and symptoms of infections that you already have after starting anti-HIV medicines. Please see the Important Safety Information for more details.
Important Information About Kaletra
Do not take Kaletra if you are allergic to any of its ingredients, including lopinavir or ritonavir. Do not take Kaletra with certain medicines, as they can cause serious problems, death, or make Kaletra less effective against HIV. Some patients taking Kaletra can develop inflammation of the pancreas and liver problems, which can cause death. Patients may develop changes in heart rhythm, large increases in triglycerides and cholesterol, diabetes, high blood sugar, changes in body fat, and/or increased bleeding in people with hemophilia. Some patients may develop signs and symptoms of serious infections they already have after starting anti-HIV medicines. Please see the Important Safety Information for more details.
The European Commission granted approval of the Norvir tablet in January. Abbott intends to register the new Norvir tablet as broadly worldwide as the Kaletra/Aluvia® (lopinavir/ritonavir) tablet. The Kaletra/Aluvia tablet is approved for sale, available (in countries where no regulatory approval is needed) or has been submitted for registration in 170 countries around the world, making it the most widely registered antiretroviral medicine available for patients across the globe.
HIV Access Programs in the United States
To help patients access this important new formulation of Norvir, Abbott is launching a Norvir co-pay support program which will be available in 2010 for all formulations of Norvir. Once a patient has paid $25 in co-pays, this program will cover up to $75 each month in patient co-pays within the first 12 months. Certain restrictions may apply.
Abbott also offers several patient assistance programs to help patients on Kaletra and Norvir access their medications. More information about other access programs can be found online by visiting Abbott's Patient Assistance Programs overview or by calling Abbott's patient access toll-free number at 1-800-222-6885.

- In 2010, the FDA approved the new Norvir tablet
Norvir® (ritonavir) is in a class of medicines called the HIV protease (PRO-tee-ase) inhibitors. Norvir is used in combination with other anti-HIV medicines to treat people with human immunodeficiency virus (HIV) infection. Norvir is for adults and for children age greater than one month and older.
Norvir does not cure HIV infection or AIDS and does not reduce the risk of passing HIV to others. People taking Norvir may still get opportunistic infections or other conditions that happen with HIV infection. Some of these conditions are pneumonia, herpes virus infections, and Mycobacterium avium complex (MAC) infections.
Important Safety Information
People who have had a serious allergic reaction to Norvir or any of its ingredients should not take Norvir. Allergic reactions ranging from hives, asthma, severe breathing issues and mild to severe skin reactions have occurred.
