Are dolutegravir/lamivudine/tenofovir (Viropil, DTG/3TC/TDF) HIV blocking drugs?

Dolutegravir (Dolutegravir), lamivudine (Lamivudine) and tenofovir (Tenofovir) (trade names Viropil, DTG/3TC/TDF) is a drug used to treat human immunodeficiency virus (HIV) infection. This drug combination belongs to the class of antiretroviral drugs that are used to inhibit the replication of HIV in the body, thereby reducing the amount of virus, maintaining immune system function, and slowing the progression of the disease.

Dolutegravir is an integrase inhibitor that can interfere with the HIV replication process in host cells. Lamivudine and tenofovir are nucleoside analogs (nucleoside reverse transcriptase inhibitors and nucleotide reverse transcriptase inhibitors), which can prevent HIV's reverse transcriptase from transcribing virusRNA toDNA, thus inhibiting viral replication.

This drug combination is often used as part of antiretroviral therapy (ART) to control HIV infection, reduce viral load, improve a patient's immune function, and slow disease progression. However, please note that information about the drug may have changed at different points in time, and it is recommended that you consult a medical professional or review the latest drug information before actual use.

Dolutegravir/Lamivudine/Tenofovir (Velop, V iropil, DTG/3TC/TDF) are not currently available in the country, so they cannot be purchased domestically and need to be purchased through foreign channels. The cheaper ones abroad are Indian generic drugs, which cost about 450 yuan.
