Description

Zidovudine a disease-resistant poison, used in patients with AIDS or HIV/AIDS related syndrome and the treatment of immunodeficiency virus (HIV) infection.

Lamivudine is a cytidine analog which acts as a potent reverse transcriptase inhibitor (nRTI). It is effective against both HIV reverse transcriptase 1 and 2, as well as hepatitis B reverse transcriptase. Lamivudine must be phosphorylated to its triphosphate form before it is active. 

Stavudine is a nucleoside analog of thymidine that inhibits reverse transcriptase and has an in vitro activity against human immunodeficiency virus (HIV). It is a white to off-white crystalline powder; melting point 161-166 ° C; soluble in water, slightly soluble in acetone, slightly soluble in lower alcohols (methanol, ethanol, isopropanol). The chemical name is (2'-3'-didehydro-2'-3'-dideoxythymidine (d4T). Reverse transcriptase is a method in which RNA can be transcribed into DNA to replicate genetic information from RNA to DNA. The enzyme, therefore also known as the RNA-reverse transcriptase inhibitor, is an antiretroviral drug that blocks the activity of retroviral reverse transcriptase. Each retrovirus has a reverse transcriptase that can be inherited. Information is transcribed from RNA into DNA. Protease inhibitors are the second class of antiretroviral drugs.


a.Used for treatment of HIV infection when CDC count is < 500/mm or

5.AIDS treatment


Function

Lamivudine is an antiretroviral agent, which belongs to a class of drugs called "nucleosides reverse transcripts inhibitors" or "NRTIs". Lamivudine mimics a nucleoside base, which blocks further construction of the virus. When combined with other antiretroviral drugs, Lamivudine can achieve a significant decrease in viral multiplication.

Stavudine is used in combination with other antiviral drugs for the treatment of type I HIV infection.
Clinical use: There are several clinical studies on the combination of this product and other antiviral drugs for HIV-infected patients
