Dimercaprol

Introduction: What is Dimercaprol?

Dimercaprol, also known as British Anti-Lewisite (BAL), is a chelating agent primarily used in the treatment of heavy metal poisoning. It was originally developed during World War II as an antidote for chemical warfare agents, particularly Lewisite, a blistering agent. Dimercaprol works by binding to heavy metals in the body, facilitating their excretion and reducing toxicity.

Uses of Dimercaprol

Dimercaprol is approved for several medical uses, including:

• Heavy Metal Poisoning: It is primarily used to treat poisoning from metals such as arsenic, mercury, and lead.
• Acute Lead Poisoning: Dimercaprol is mainly used in severe or acute cases, often in combination with EDTA.
• Arsenic Poisoning: It is used in cases of arsenic exposure, helping to alleviate symptoms and reduce metal levels in the body.
• Mercury Poisoning: Dimercaprol can be used to treat mercury toxicity, particularly in cases of organic mercury exposure.

Kon sa unsang paagi kini buhat

Dimercaprol functions as a chelating agent, which means it binds to heavy metals in the bloodstream. When dimercaprol enters the body, it forms stable complexes with toxic metals, making them less harmful. These complexes are then excreted via urine or bile. By removing these metals, dimercaprol helps to alleviate the symptoms of poisoning and prevent further damage to organs.

Dosis ug Pagdumala

The dosage of dimercaprol varies based on the condition being treated and the patient's age.

• Mga hamtong: The typical dosage for adults is 35 mg/kg intramuscularly every 4 hours for 23 days, followed by a maintenance dose of 12 mg/kg every 6 hours for up to 10 days.
• Pediatrics: For children, the dosage is similar, but it is crucial to consult a pediatrician for the exact amount based on the child's weight and condition.

Dimercaprol is administered via injection, typically intramuscularly, and should be given in a clinical setting under medical supervision.
