- MetabollsmIt is extensively metabolised in the liver to produce two metabolites, the main circulating metabolite (85%) being the inactive carboxylic acid derivative. Clopidogrel is oxidised to 2-oxo-clopidogrel with further hydrolysis to produce the active thiol derivative, which has not yet been identified in plasma.
- Half lifeThe elimination half-life of the inactive metabolite is approx. 8 h.
- ExcretionClopidogrel and its metabolites are equally excreted in urine and faeces.
- Urinary ExcretionN/A
- Clerance10 mg/L/h
- ToxicityA single case of deliberate overdose, during clinical trials, has been reported. A 34-year-old woman swallowed a single dose of 1050 mg (equivalent to 14 standard 75 mg tablets) clopidogrel with no associated undesirable effects. No special therapy was needed.
