Explain Lamivudine
It is probably the best tolerated of the NRTIs and can be taken once or twice daily. An increase in viral load during treatment with a lamivudine-containing regimen is often an indication of resistance to lamivudine. Lamivudine-resistant strains may be cross-resistant to zalcitabine and emtricitabine, and may have low-level resistance to abacavir, ddI and ddC.
