Lopinavir/Ritonavir tablets (Lopinavir/Ritonavir) Chinese instructions

[drug name]:

Lopinavir and ritonavir tablets

[Indications]:

Lopinavir and ritonavir tablets are an antiretroviral drug used to treat human immunodeficiency virus (HIV) infection. It is often used as part of combination anti-HIV treatment (antiretroviral therapy, ART) to reduce viral load, maintain immune system function, and slow disease progression. This medicine is usually used to treat HIVinfected adults and children.

[Mechanism of action]:

Lopinavir and ritonavir tablets belong to the class of protease inhibitors (Protease Inhibitors, PIs). Its mechanism of action is to inhibit the protease activity of HIV, thereby preventing the replication and maturation of the virus in host cells. Specifically, lopinavir and ritonavir interfere with viral proteases and prevent the normal assembly and release of viral particles, thereby reducing HIV's ability to replicate and spread.

[Pharmacology]:

When used together, lopinavir and ritonavir can significantly reduce the viral load, maintain immune system function, and reduce virus damage to host cells. This helps control the progression ofHIVinfection and reduces the risk of complications. The combined use of lopinavir and ritonavir enhances their bioavailability, making the drugs more easily absorbed and maintained within the effective concentration range.
