Introduction to Epivir (Lamivudine) 100mg
Epivir (Lamivudine) 100mg is a prescription antiviral medicine used to treat chronic hepatitis B infection and as part of HIV therapy. It belongs to a class of nucleoside reverse transcriptase inhibitors (NRTIs) that prevent viral replication, helping to control infection and reduce liver damage.
Lamivir (Lamivudine) 100mg is classified under Prescription Medicines, Antiviral Medicines, Hepatitis Treatment Drugs, and Oral Antiretroviral Therapies. It contains Lamivudine, which works by inhibiting reverse transcriptase, an enzyme necessary for viral replication.
In some markets, Lamivir 100mg is available as a generic brand containing the same active ingredient Lamivudine, offering similar therapeutic benefits when prescribed by a qualified healthcare professional.
What Is Epivir (Lamivudine)?
Epivir is the original brand name for Lamivudine, widely used to manage hepatitis B and HIV infections.
Lamivudine belongs to a class of medicines known as Nucleoside Reverse Transcriptase Inhibitors (NRTIs). These medicines help block viral replication and reduce viral load in the body.
Generic versions such as Lamivir 100mg contain the same active compound and may be used depending on physician recommendation and availability.
Drug Class and Mechanism of Action
Lamivudine is classified as an antiretroviral and antiviral agent with nucleoside reverse transcriptase inhibitory properties.
How Lamivudine Works
It works through the following mechanisms:
- Inhibits reverse transcriptase enzyme in viruses
- Prevents viral DNA synthesis
- Reduces viral replication and viral load
Through these actions, Lamivudine helps control chronic hepatitis B infection and supports HIV therapy.
How Epivir Works in the Body
Viruses like hepatitis B and HIV replicate inside human cells using reverse transcriptase. Epivir blocks this enzyme, slowing or stopping viral replication.
Key Actions of Lamivudine
- Reduces hepatitis B viral load
- Prevents liver damage progression
- Supports combination therapy in HIV treatment
Generic versions such as Lamivir deliver the same active compound for effective antiviral therapy when prescribed appropriately.
