개요
트리엔틴은 주로 개의 구리 관련 간병증 치료에 사용되는 경구용 구리 킬레이트제입니다. 페니실라민의 위장관 부작용(예: 심한 구토)을 견디지 못하는 환자에게 중요한 대안 치료제 역할을 합니다.
작용 기전
Trientine acts as a polyamine chelating agent. It binds to systemic copper to form a stable, water-soluble complex (a chelate) that is subsequently eliminated from the body via urinary excretion.
- Affinity Profile: Trientine has a greater affinity for plasma copper compared to penicillamine.
- Conversely, penicillamine has a higher affinity for tissue copper.
- By binding circulating copper, trientine creates a concentration gradient that gradually pulls stored copper out of hepatic tissues for elimination.
안전성·주의사항
금기사항
- Hypersensitivity to trientine
- Cystinuria
- Rheumatoid arthritis
- Biliary cirrhosis
- No specific contraindications available in the monograph, but should be used with caution in patients without confirmed copper storage disease.
부작용
- Acute renal failure (rare but reported in dogs)
- Iron deficiency anemia (with long-term use)
- Topical contact dermatitis (if powder contacts skin)
- Nausea
- Vomiting
- Abdominal pain
- Melaena (dark, tarry stools)
- Weakness
- Copper deficiency (with chronic therapy)
주의
Teratogenicity: Trientine is a potential teratogen (FDA Category C). It should only be used in pregnant animals when the benefits to the mother clearly outweigh the risks to the offspring. Exercise caution in nursing patients.
Handling Warning: The drug can cause topical dermatitis. It must be given in an intact capsule and should never be opened or sprinkled on food. If the powder accidentally contacts human or animal skin, wash the area immediately with water.
약물 상호작용
Iron and trientine mutually inhibit the absorption of one another. Separate doses by at least 2 hours.
Trientine may chelate zinc and other essential minerals, reducing their absorption. Separate doses by at least 2 hours.
Inhibits absorption of iron; separate doses by a minimum of 2 hours
Inhibits absorption of zinc; separate doses by a minimum of 2 hours
Inhibits absorption of minerals; separate doses by a minimum of 2 hours
모니터링
- Periodic quantitative hepatic copper levels (via liver biopsy)
- Renal function parameters (BUN, Creatinine, SDMA, Urinalysis) due to the risk of acute renal failure
- Complete Blood Count (CBC) to monitor for iron deficiency anemia
- Hepatic copper concentrations (via biopsy)
- Liver enzymes (ALT, AST, ALP)
- Clinical signs of copper deficiency (e.g., anemia, weakness)
- Gastrointestinal tolerance
약동학
흡수
Poorly absorbed from the gastrointestinal tract.
분포
Widely distributed, but has greater affinity for plasma copper than tissue copper.
대사
Metabolized via acetylation.
배설
Excreted primarily in the urine as a copper-trientine complex.
과다투여
Little information is available regarding acute toxicity in veterinary species. In human medicine, a case of a patient ingesting 30 grams of trientine without significant morbidity has been reported. If a massive overdose occurs in a pet, standard gastrointestinal decontamination and supportive care are recommended.

보관·안정성
Store trientine capsules in the refrigerator (2-8°C) in tightly closed containers. The powder is highly hygroscopic (absorbs moisture from the air).
보호자 정보
효과를 극대화하기 위해 가능한 공복(식사 1~2시간 전)에 투여하십시오. 공복 투여로 인해 구토나 식욕 부진이 발생하면 아주 적은 양의 음식과 함께 투여할 수 있습니다. 캡슐을 열어 음식에 가루를 뿌리지 마십시오. 가루가 피부 자극을 유발할 수 있습니다. 피부에 닿은 경우 즉시 물로 씻어내십시오. 약은 냉장고에 밀폐 용기에 보관하십시오.
