What diseases does trientine mainly treat?

Trientine(Trientine) is a metal chelating agent mainly used to treat Wilson's Disease, a rare but serious genetic metabolic disease. The disease is caused by copper metabolism disorders caused by mutations in the ATP7B gene. The patient's body cannot normally excrete excess copper ions, resulting in abnormal copper deposition in the liver, brain, eyes and other tissues, eventually causing a series of clinical symptoms, including progressive liver damage, neuropsychiatric disorders, and corneal K-F rings. If left untreated, Wilson's disease can cause irreversible organ damage and even be life-threatening.

The core of the therapeutic mechanism of trientine lies in its selective binding ability to copper. It can form a soluble complex with free copper in the body and be excreted through urine, thereby effectively removing excess copper from the body, reducing tissue burden and preventing further damage. Compared with the traditional copper chelator penicillamine (Penicillamine), trientine is better tolerated and is especially suitable for patients who are intolerant to penicillamine or experience adverse reactions. In recent years, more and more guidelines have recommended trientine as first-line treatment, especially in patients with impaired liver function.

In addition to Wilson's disease, some studies have also explored the potential of trientine in other copper-related diseases, including certain types of copper-accumulating liver disease or rare metabolic lesions, but it has not yet become a recognized indication. During treatment, doctors usually dynamically adjust the dose of trientine based on the patient's copper load, clinical symptoms, and biochemical indicators, supplemented by regular monitoring of copper and zinc levels to evaluate efficacy and avoid excessive decoppering. Additionally, because trientine does not contain sulfur groups, reducing certain allergic reactions or skin toxicity, it is considered one of the safer options in terms of tolerability.
