How long does one box of Trientine last?

Trientine(Trientine) is a chelating agent used to treat hepatolenticular degeneration (Wilson's disease; rare disease). It is especially suitable for patients who are intolerant to penicillamine, including children ≥5 years old and adults. Wilson's disease is a disease of abnormal copper metabolism. Copper ions accumulate in the liver, brain and other tissues in the body, leading to liver dysfunction and nervous system damage. Trientine forms a soluble complex with excess copper ions in the body, promoting the excretion of copper through urine, thereby reducing the copper load in the body and improving clinical symptoms.

Regarding the medication cycle and dosage, in general, the oral dosage of trientine needs to be adjusted according to the patient's age, weight and disease severity. For adult patients, the conventional dose is 800-1600 mg per day, taken in divided doses, while for children, it is adjusted individually based on body weight. Trientine tablets are usually 200 mg/tablet, so a box of 100 tablets can theoretically maintain the standard therapeutic dose for about a month, but the specific medication time will vary depending on the individual patient's dose.

In clinical use, in order to ensure efficacy and safety, patients need to regularly monitor serum copper, serum ceruloplasmin levels and liver function indicators during medication in order to adjust the dose or extend the medication cycle. It is worth noting that patients with Wilson's disease usually need long-term or even lifelong use of chelators to maintain copper homeostasis. Therefore, the usage time of a box of medicines is only a short-term treatment reference, and the entire course of treatment should be continuously monitored and adjusted under the guidance of a professional doctor.

In addition, trientine is better absorbed orally, but it should be taken on an empty stomach to improve bioavailability and avoid simultaneous intake with copper or iron-containing foods that may affect the efficacy of the drug. Patients should strictly abide by the dosage and dosage intervals during medication, and do not increase or decrease the dosage at will to prevent serum copper from falling too quickly or insufficiently, which may lead to liver damage or worsening of neurological symptoms.
