  • What Is Lamivudine (Epivir)?

    Lamivudine (Epivir) is the reverse transcriptase inhibitor suitable for treating HIV and Hepatitis B Infections in the body.

    These are reverse transcriptase inhibitor, which has higher efficiency in treating HIV as well as hepatitis B.

    At Grant Pharmacy, we are proud to offer a beacon of hope in the form of Lamivudine, marketed under the brand name Epivir.

    Normally, the HIV causes the Acquired Immunodeficiency Syndrome (AIDS).

    Lamivudine is not the cure for AIDS or HIV. The epivir hbv 100 mg tablets are useful for treating the chronic hepatitis B and HIV.

    Normally, the Epivir is available in the generic form.

    Lamivudine (Epivir) is widely called as the 3TC and it is the Nucleoside Reverse Transcriptase Inhibitor (NRTI).

    The lamivudine needs to be taken only by the mouth once or twice daily. 

    How Does Lamivudine (Epivir) Work?

    Lamivudine (Epivir) is an NRTI or Nucleoside Reverse Transcriptase Inhibitor, which is a nucleoside analogue. These are also Phosphorylated intracellularly for the 5'-triphosphate metabolite and lamivudine triphosphate (L-TP).

    Normally, this nucleoside analogue is enabled with viral DNA by HIV reverse transcriptase as well as HBV polymerase. It will completely result in the termination of the DNA chain.

    Taking the epivir medication is efficient for blocking the enzyme or protein found in HIV and HBV. These involve reverse transcriptase, which helps the virus to make copies of itself.

    Lamivudine (Epivir) blocks reverse transcriptase, so it will automatically prevent HIV and HBV.

    These viruses could not be making copies of it before spreading.

    Lamivudine is helpful widely for easily treating HIV. These are used along with other HIV medications for helping to control HIV infections.

    These help to decrease the amount of HIV in the body, and the immune systems can extensively work better.

    It also lowers the chance of getting HIV complications like cancer, infections and many more.

    Lamivudine especially belongs to a Class of Drugs called nucleoside reverse transcriptase inhibitors. These decrease the risks involved in spreading the HIV disease.

    It will be a significant option to continue to take the medication to get the best results. Knowing the lamivudine uses lets to easily reduce the effect of the HIV in the body.

    The medication acts as the best barrier for the HIV and Hepatitis B Infections to spread across the body.

    Reverse transcriptase inhibitors, as well as zalcitabine analogues, involve the sulfur atom.

     These also replace 3' carbon of pentose ring so they are well efficient for treating the Human Immunodeficiency Virus Type 1 (HIV-1) as well as hepatitis B (HBV).

    Lamivudine is enabled with NRTI, which acts against the Human Immunodeficiency Virus Type 1 and HBV.

    Epivir works mainly by disrupting the DNA synthesis of the virus in the body and assures in lowering the effect of the virus. But it is not the cure for HIV or HBV.

    Lamivudine creates active metabolites when they are phosphorylated. These also compete with incorporating the viral DNA.

    Normally, the DNA incorporation is enabled with the lamivudine metabolites that would inhibit competitively HIV reverse transcriptase enzyme.

    It acts as the chain terminator in DNA synthesis assuring better stability.

    It also decreases the 3'-OH group that is incorporated with nucleoside analogues to prevent the development of the 5' to 3' Phosphodiester linkage. These are essential for DNA chain elongation and other synthesis in the body.
