Mercapton (Dimercaptosuccinic Acid)

Dimercaptosuccinic Acid, the active ingredient in Mercapton, is a chelating agent presented as an intravenous solution for the treatment of heavy metal poisoning, including lead and mercury toxicity, in patients requiring rapid detoxification. It works by binding divalent metal ions to form complexes that are eliminated in the urine.

GNH USA supplies Mercapton as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide. The company ensures quality compliance with EU standards and provides reliable global distribution.

Mercapton is a chelating agent used to treat heavy metal poisoning. - Lead poisoning: facilitates urinary excretion of lead, reducing blood lead levels. - Mercury poisoning: binds mercury ions, enhancing elimination and mitigating toxicity. - Other heavy metal toxicity: chelates various divalent metals such as arsenic and cadmium, supporting detoxification.

Adverse reactions to Mercapton may vary in frequency and severity.

Common Side Effects: - Nausea: mild gastrointestinal discomfort. - Headache: transient cranial pain. - Flushing: temporary skin redness. - Hypotension: mild drop in blood pressure.

Serious or Rare Side Effects: - Acute renal failure: sudden loss of kidney function. - Anaphylaxis: severe allergic reaction with respiratory distress. - Hepatotoxicity: liver enzyme elevation. - Hemolysis: destruction of red blood cells.

When using Mercapton, clinicians should observe several safety measures. - Renal function monitoring: assess creatinine and urine output before and during therapy. - Electrolyte balance: check serum electrolytes, especially potassium and calcium. - Concomitant nephrotoxic drugs: avoid or adjust dosing of other kidney‑affecting medications. - Pregnancy and lactation: use only if potential benefit justifies risk, as safety data are limited. - Pediatric use: dose adjustment required; monitor growth and development. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Mercapton may interact with other medicines, affecting efficacy or safety.

Major Interactions (Avoid): - Penicillamine: concurrent use can reduce chelation effectiveness and increase toxicity. - High-dose zinc supplements: may interfere with metal binding and diminish therapeutic effect.

Moderate Interactions (Monitor Closely): - Loop diuretics: may enhance renal excretion of electrolytes, requiring monitoring. - ACE inhibitors: potential additive effect on blood pressure, monitor for hypotension. - Anticoagulants (warfarin): chelation may alter plasma protein binding, affecting INR.
