Kaletra is used in treatment of HIV infections, which may result in AIDS (acquired immune deficiency syndrome).
General information
Kaletra is used in treatment of HIV infections, which may result in AIDS (acquired immune deficiency syndrome). The drug is not intended to cure HIV or AIDS, but to prevent HIV cells from multiplying in the body. It may be used alone or in conjunction with other HIV medications as part of HIV/AIDS treatment.

The drug is a combination of two medications, Lopinavir and low dose Ritonavir. Lopinavir belongs to a group of medicines known as protease inhibitors. It inhibits activity of HIV protease, a chemical essential for HIV cells to multiply. Ritonavir suppresses the metabolism of Lopinavir which helps in keeping increased levels of Lopinavir in the blood.

Kaletra is available in the form of a tablet and an oral solution. The tablets are available in two strengths which are color coded for easy identification. The yellow tablet contains 200mg of Lopinavir and 50mg of Ritonavir while the pale yellow colored tablet contains 100 mg of Lopinavir and 25 mg of Ritonavir. The oral solution contains 80 mg Lopinavir and 20 mg Ritonavir per milliliter.

Kaletra is a prescription medication and may cause side effects if used for unintended purposes. Therefore, you should buy Kaletra only on doctor’s recommendation.
