Pharmacology
Indication Indicated in combination with other antiretroviral agents for the treatment of HIV-infection.
Pharmacodynamics Lopinavir is an antiretroviral of the protease inhibitor class. Inhibiting HIV-1 protease (responsible for protein cleavage), results in selectively inhibiting the cleavage of HIV gag and gag-pol polyproteins, thereby preventing viral maturation.
Mechanism of action Lopinavir inhibits the HIV viral protease enzyme. This prevents cleavage of the gag-pol polyprotein and, therefore, improper viral assembly results. This subsequently results in non-infectious, immature viral particles.
Absorption Administered alone, lopinavir has insufficient bioavailability; however, like several HIV protease inhibitors, its blood levels are greatly increased by low doses of ritonavir, a potent inhibitor of cytochrome P450 3A4.
Volume of distribution Not Available
Protein binding Lopinavir is highly bound to plasma proteins (98-99%).
Metabolism

Hepatic. Lopinavir is extensively metabolized by the hepatic cytochrome P450 system, almost exclusively by the CYP3A isozyme.
Route of elimination Not Available
Half life Not Available
Clearance Not Available
Toxicity Although human experience of acute overdosage with lopinavir is limited, accidental ingestion of the product by a young child could result in significant alcohol-related toxicity and could approach the potential lethal dose of alcohol.

Enzymes

1. Cytochrome P450 3A4

Actions: substrate, inhibitor

Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1'-hydroxylation and midazolam 4- hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. The enzyme also hydroxylates etoposide
