How to buy efavirenz/emtricitabine/tenofovir (EFV+FTC+TDF, Viraday)? What are the purchasing channels?

Efavirenz/Emtricitabine/Tenofovir (EFV+FTC+TDF), often With the trade name "Viraday", it is a compound antiretroviral drug used to treat human immunodeficiency virus (HIV) infection.

Efavirenz/Emtricitabine/Tenofovir (EFV+FTC+TDF, Viraday) is not currently on the market in China, so patients cannot purchase it domestically and need to purchase it through overseas purchasing channels. The cheaper ones abroad are mainly Indian generic drugs, which cost around 380 yuan.

The drug is a combination of three different ingredients, each with a specific mechanism of action that works synergistically to inhibit the replication and spread of the HIV virus. Efavirenz (Efavirenz, EFV) is a non-nucleoside reverse transcriptase inhibitor (NNRTI). It interferes with the replication of the viral genome by inhibiting the reverse transcriptase of HIV, thereby reducing the replication of the virus in host cells. Emtricitabine (Emtricitabine, FTC) is a nucleoside reverse transcriptase inhibitor (NRTI). It inhibits the replication process of the virus by interfering with the enzyme activity of HIV. Tenofovir (Tenofovir disoproxil fumarate, TDF) is also a nucleoside reverse transcriptase inhibitor (NRTI). It can inhibit the reverse transcriptase activity of HIV, thereby blocking the replication of the viral genome.

These three ingredients combined make up efavirenz/emtricitabine/Tenofovir has become a highly effective anti-HIV therapy. It inhibits virus replication through multiple pathways, reduces the amount of virus in the body, helps control the progression of the disease, improves the patient's immune function, and delays the progression of HIV infection to AIDS. However, it is worth noting that the use of efavirenz/emtricitabine/tenofovir treatmentHIV needs to be carried out under the guidance of a professional doctor, and regular monitoring and follow-up are required during the treatment process.
