Abstract:
We report the case of a 56-year-old woman with a 7-year history of metastatic cancer who presented with severe copper deficiency following self-treatment with the copper-chelating agent tetrathiomolybdate. This compound was used with the aim of inhibiting tumour angiogenesis and was obtained from the USA by placing an order on the internet. The patient exhibited severe neutropenia as her serum copper concentration fell from 19.8 micromol/L to 3.3 micromol/L and her caeruloplasmin concentration from 35 mg/dL to 4 mg/dL.

Antidotes
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...
