How it works
From the US prescribing label for the same active substance (Lamivudine). It describes the substance, not this exact product.
Lamivudine is an antiviral agent with activity against HBV [see Microbiology ( 12.4 )].
Lamivudine is not significantly metabolized by cytochrome P450 enzymes.
The majority of lamivudine is eliminated unchanged in urine by active organic cationic secretion.
Effects of Food on Oral Absorption: Lamivudine tablets (HBV) may be administered with or without food.
