Kaletra (Generic Lopinavir and Ritonavir)
Actual product appearance may differ slightly.
Why is this medication prescribed?
Kaletra is a medication that contains a combination of two active ingredients, lopinavir and ritonavir. It is primarily prescribed for the treatment of HIV infection (human immunodeficiency virus).
HIV attacks the immune system, specifically targeting CD4 cells, which are crucial for the proper functioning of the immune system. Kaletra is classified as an antiretroviral medication and is used as part of highly active antiretroviral therapy (HAART) to control HIV infection and slow down the progression of the disease.
Lopinavir, one of the components of Kaletra, belongs to a class of drugs called protease inhibitors. It works by inhibiting the action of the HIV protease enzyme, which is necessary for the virus to replicate and produce new viral particles. By blocking this enzyme, Kaletra helps to reduce the viral load in the body and prevent further damage to the immune system.
Ritonavir, the other component of Kaletra, is a pharmacokinetic enhancer. It helps to increase the effectiveness and bioavailability of lopinavir by inhibiting certain enzymes in the liver that break down lopinavir. Ritonavir allows lopinavir to reach therapeutic levels in the body and stay active for a longer period of time.
How should this medicine be used?
Kaletra should be used exactly as prescribed by a healthcare professional. It is typically available in tablet form, and the dosage and treatment duration will be determined by your healthcare provider based on your specific condition.
Here are some general guidelines for using Kaletra:
- Follow the prescribed dosage: Take the medication exactly as instructed by your healthcare provider. Do not take more or less than the prescribed dose, and do not stop taking it without consulting your doctor.

- Stick to a schedule: Try to take Kaletra at the same time(s) every day to maintain a consistent level of the medication in your body. This will help maximize its effectiveness.

Other uses for this medicine
In addition to its primary use in the treatment of HIV infection, Kaletra may also be used for other purposes as determined by a healthcare professional. However, it’s important to note that the off-label uses of Kaletra are not as extensively studied or approved as its primary use for HIV treatment. Some off-label uses may include the treatment of certain viral infections or in certain situations where it may be deemed appropriate by a healthcare provider.
