It also cross-links DNA strands leading to inhibition of DNA, RNA and protein synthesis. Absorption: Poorly absorbed from the GI tract (oral). Distribution: Crosses the blood-brain barrier; localised in the liver. Protein-binding: 5%. Metabolism: Extensively hepatic. Excretion: Urine (as unchanged drug).
