Description: Altretamine, a synthetic triazine derivative, is a cytotoxic antineoplastic agent structurally similar to triethylenemelamine, although its mode of action may be different. While its cytotoxic effect is not fully characterised, it is theorised that its activated oxidative N-demethylation metabolites bind to and damage DNA.
Absorption: Well absorbed from the GI tract. Time to peak plasma concentration: 0.5-3 hr.
Distribution: Distributed into tissues high in lipid content and tumour tissues.
Metabolism: Rapidly and extensively metabolised in the liver via oxidative N-demethylation into pentamethylmelamine and tetramethylmelamine.
Excretion: Via urine (90%, mainly as metabolites and <1% as unchanged drug). Elimination half-life: 4-10 hr.
