Ritonavir

Drug Details

Ritonavir, marketed under the brand name Norvir, is an oral medication used to treat human immunodeficiency virus (HIV) infections as part of an antiretroviral therapy regimen. It is available in tablet, powder, and solution forms. The medication works by inhibiting a protein called protease, which is essential for the virus to reproduce and spread. By blocking this protein, ritonavir helps prevent HIV from infecting healthy cells. Some common side effects include diarrhea, nausea, vomiting, and abdominal pain. It is important to inform your healthcare provider about all medications you are taking, as ritonavir can interact seriously with other drugs. Always consult your doctor, nurse, or pharmacist before starting new medications or treatments.
