Class of Drugs – Nucleoside Reverse Transcriptase Inhibitors

Molecular Formula – C8H11N3O3S

Molecular Weight – 229.26 g/mol

Working: This nucleoside reverse transcriptase inhibitor medicine Lamivudine does not cure infection with HIV or HBV. It helps slow the progression of these diseases by restricting the ability of the viruses to replicate. HIV and HBV need an enzyme called reverse transcriptase to replicate and spread in the body. This drug blocks this enzyme that prevents HIV and HBV from replicating as quickly, slowing down the spread of the viruses.

Uses: The medicine is used with other HIV drugs to control HIV infection. It decreases the amount of HIV in the body so the immune system can work better. This lowers a chance of getting HIV complications like new infections, cancer and improves the quality of life. Lamivudine belongs to a class of drugs called nucleoside reverse transcriptase inhibitors.
