Information on Tablets A-Z
Generic ingredients: Lopinavir, Ritonavir
Why is this drug prescribed: Kaletra combats the human immunodeficiency virus (HIV). HIV is the deadly virus that undermines the infection-fighting capacity of the body's immune system, eventually leading to AIDS. Kaletra is a combination of two drugs, lopinavir and ritonavir (Norvir), both of which fall into the drug category known as protease inhibitors. When taken along with other HIV drugs, Kaletra lowers the amount of the virus circulating in the bloodstream. However, it does not completely eradicate the virus, and you may continue to develop the rare infections that attack when the immune system weakens. It's also important to remember that Kaletra does not eliminate the danger of transmitting the virus to others.
