Pharmacology: |
Due to its oily nature, dimercaprol is not absorbed orally and its administration requires deep intra-muscular injection that is extremely painful and allergenic. It was found to mobilize and relocate lead to the brain, increasing its neurotoxic effects. Although treatment with dimercaprol increases the excretion of cadmium, there is a concomitant ...

Mechanism of Action: | The sulfhydryl groups of dimercaprol form complexes with certain heavy metals thus preventing or reversing the metallic binding of sulfhydryl-containing enzymes. The complex is excreted in the urine. |
Absorption: | After intra-muscular injection. |
Route of elimination: | Urine. |
Half Life: | The drug has a short half life. |
Toxicity: | The intramuscular LD50 in rats is approximately 105 mg/kg; intraperitoneally 140 mg/kg. The intraperitoneal LD80 in mice is approximately 125 mg/kg. Dimercaprol has been shown in animal experiments to increase brain deposition of arsenite, organic mercury compounds and increase the toxicity of cadmium and lead. Dimercaprol has been shown to induce seizure in animal studies and also is nephrotoxic. |
