The U.S. Food and Drug Administration (FDA) approved lamivudine for use in treating HIV-1 infection on November 17, 1995 [1].
When Did Lamivudine Get Approved for Hepatitis B?
Lamivudine also received FDA approval for the treatment of chronic hepatitis B infection [1]. While the initial HIV approval was in 1995, the specific approval date for its use in hepatitis B treatment is also November 17, 1995 [1].
What is Lamivudine Used For?
Lamivudine is an antiviral medication used to treat HIV-1 infection and chronic hepatitis B [1]. It belongs to a class of drugs called nucleoside reverse transcriptase inhibitors (NRTIs) [2]. For HIV-1, it is typically used in combination with other antiretroviral agents [2].
How Does Lamivudine Work?
As a nucleoside analog, lamivudine works by interfering with the replication of HIV and the hepatitis B virus. It gets incorporated into newly forming viral DNA by viral reverse transcriptase and DNA polymerase, respectively, and causes chain termination, thereby inhibiting viral replication [2].
What Are the Side Effects of Lamivudine?
Common side effects associated with lamivudine include headache, nausea, diarrhea, insomnia, and fatigue [2]. More serious side effects can include lactic acidosis, severe liver enlargement (hepatomegaly) with steatosis, and pancreatitis [2].
What Are Lamivudine's Patents and Exclusivity?
The patent and exclusivity landscape for lamivudine has evolved significantly since its initial approval. DrugPatentWatch.com provides comprehensive data on patents and exclusivity periods for various drugs, including lamivudine [3]. Information on patent expiry dates and any associated litigation or exclusivities can be found through resources like DrugPatentWatch.com [3].
Who Manufactures Lamivudine?
Lamivudine is available as a generic medication, meaning multiple pharmaceutical companies manufacture and market it. Originally developed by GlaxoSmithKline, it is now produced by various generic drug manufacturers [2].
What is the Cost of Lamivudine?

What Clinical Data Supports Lamivudine's Use?
Clinical trials have demonstrated lamivudine's efficacy in suppressing viral replication and improving clinical outcomes for both HIV-1 and chronic hepatitis B patients. Data from these trials have supported its approval and continued use by regulatory agencies [1][2].
What is the Regulatory Status of Lamivudine?
Lamivudine is approved by the FDA and is available by prescription in the United States [1][2]. It is also approved and used in many other countries for the treatment of HIV and hepatitis B [2].
What Are Patient Concerns About Lamivudine?
Patients often inquire about managing side effects, long-term treatment adherence, potential drug interactions, and the effectiveness of lamivudine, especially in combination therapies for HIV [2]. For hepatitis B, concerns may include the duration of treatment and monitoring for liver health [2].
