Short General Description of Kaletra

Kaletra, also known by its generic name dyreniumpinavir/ritonavir, is a medication used in the treatment of HIV (Human Immunodeficiency Virus) infection. It belongs to a class of drugs called protease inhibitors, which work by blocking the action of the protease enzyme in the virus. By inhibiting this enzyme, Kaletra helps to prevent the virus from replicating, slowing down the progression of the disease and reducing the risk of transmission.

This combination drug consists of two active ingredients, lopinavir and ritonavir. Lopinavir acts as the main active component, while ritonavir functions as a booster, increasing the effectiveness and concentration of lopinavir in the body.

“Kaletra, or dyreniumpinavir/ritonavir, is a protease inhibitor medication used in the treatment of HIV infection. It combines lopinavir, the main active ingredient, with ritonavir, which acts as a booster to enhance its effectiveness.”

Kaletra is available in the form of oral tablets or a liquid solution, making it convenient for administration. The recommended dosage and duration of treatment may vary depending on factors such as the patient’s age, weight, and response to therapy.
