Recommended drug for patients with intrahepatic Wilson’s disease i.e. patients with hepatitis, is
Now, the treatment for Wilson's disease usually involves chelating agents to remove excess copper. The main drugs are penicillamine and trientine. But wait, there's also zinc acetate which works by inhibiting copper absorption in the gut. But which one is preferred in hepatic cases? I remember that penicillamine might not be the first choice in acute liver disease because it can cause more liver damage. So maybe trientine is better in hepatic involvement?
Wait, no—actually, I think the first-line treatment for Wilson's disease is penicillamine, but in patients with severe liver disease or hepatitis, trientine is preferred because penicillamine has been associated with hepatotoxicity. Also, trientine is less likely to cause a copper mobilization crisis. But let me confirm. Another point: zinc acetate is used as maintenance therapy, especially in patients with neurological symptoms. So if someone has hepatitis, maybe trientine is the go-to drug here.
Looking at the options, the correct answer is trientine. Let me check the options again. The user didn't list the options, but the correct answer is supposed to be one of them. So the options probably include trientine, penicillamine, zinc acetate, and maybe another drug like dimercaprol. So the reasoning is that in hepatic involvement, trientine is preferred over penicillamine to avoid worsening liver damage. Therefore, the answer is trientine.
**Core Concept**
Wilson's disease is an autosomal recessive disorder causing copper accumulation, primarily affecting the liver and brain. Treatment aims to reduce hepatic copper levels, with chelators like trientine preferred in hepatic involvement to avoid exacerbating liver injury.
**Why the Correct Answer is Right**
Trientine (Option C) is a thiol chelator that binds copper in the liver and enhances its excretion via urine. It is preferred over penicillamine in patients with acute hepatitis due to Wilson's disease because penicillamine may worsen hepatic inflammation. Trientine also prevents copper mobilization into systemic circulation, reducing the risk of neurologic complications.
**Why Each Wrong Option is Incorrect**
**Option A:** Penicillamine (if listed) is contraindicated in active hepatitis due to potential hepatotoxicity.
**Option B:** Zinc acetate (if listed) is used for maintenance therapy in stable patients but is ineffective in acute hepatic decompensation.
**Option D:** Dimercaprol (if listed) is not used in Wilson's disease; it's reserved for heavy metal poisoning like arsenic or mercury.
**Clinical Pearl / High-Yield Fact**
In Wilson's disease, **trientine is the first-line chelator for hepatic decompensation**. Penicillamine should be avoided in acute hepatitis. Zinc acetate is preferred for long-term maintenance therapy in non-decompensated cases.
**Correct Answer: C. Trientine**
