The following dosing information is available for TRIENTINE HCL (trientine hcl):
Recommended dosage regimens of trientine hydrochloride are based on limited clinical experience; studies have not been conducted evaluating specific doses and/or dosing intervals.
Trientine tetrahydrochloride is not substitutable on a mg-per-mg basis with other trientine products.
If switching from a trientine hydrochloride formulation to trientine tetrahydrochloride, note that the content of the active moiety (trientine base) is not the same as trientine tetrahydrochloride. A 250 mg capsuleof trientine hydrochloride contains 167 mg of trientine base; in contrast, each 300 mg tablet of trientine tetrahydrochloride contains 150 mg of trientine base.

A 250 mg capsuleof trientine hydrochloride contains 167 mg of trientine base; in contrast, each 300 mg tablet of trientine tetrahydrochloride contains 150 mg of trientine base.
Trientine hydrochloride capsules are administered orally on an empty stomach, at least 1 hour before or 2 hours after meals, and at least 1 hour apart from any other oraldrug, food, or milk. The total daily dosage should be administered in divided doses 2-4 times daily. The capsules should be swallowed whole with water and should not be opened or chewed.
Because of the potential for contact dermatitis, any site of exposure to the capsule contents should be washed immediately with water. Store trientine hydrochloride capsulesin a tightly closed container in the refrigerator at 2-8oC. Trientine tetrahydrochloride tablets are administered on an empty stomach, at least 1 hour before or 2 hours after meals, and at least 1 hour apart from any other oral drug, food, or milk.
The total daily dosage should be administered in divided doses 2 times daily. The tablets should be swallowed whole without crushing, chewing, or dissolving. If a patient has difficulty swallowing a tablet whole, the scored tablet can be divided into 2 equal halves.
Do not remove trientine tetrahydrochloride tablets from blister packs until just before dosing and do not store tablets for future use after the blister has been opened. Store trientine tetrahydrochloride tablets at 20-25degreesC; excursions permitted between 15-30degreesC.

The following drug interaction information is available for TRIENTINE HCL (trientine hcl):
There are 0 contraindications.
There are 0 severe interactions.
There are 2 moderate interactions.
The clinician should assess the patient’s characteristics and take action as needed. Actions required for moderate interactions include, but are not limited to, discontinuing one or both agents, adjusting dosage, altering administration.
| Drug Interaction | Drug Names |
|---|---|
| Trientine/Iron Salts, Oral SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Trientine is a chelating agent. Concurrent administration with iron may reduce the absorption of both trientine and iron. CLINICAL EFFECTS: Iron may decrease the levels and clinical effects of trientine, and trientine may reduce serum iron levels. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Avoid use of iron salts within 2 hours of trientine dose. Monitor clinical status for decreased effectiveness and adjust the trientine dose if necessary. DISCUSSION: Multivitamins with low doses of iron may decrease trientine absorption so ensure patient is aware of the risks. Also, as patients may be unaware which foods contain iron, instruct patients to take trientine on an empty stomach, at least one hour before meals or two hours after food or milk. |

| Trientine/Selected Minerals, Oral SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed. MECHANISM OF ACTION: Mineral supplements may bind to trientine and block its absorption. CLINICAL EFFECTS: The levels and clinical effects of trientine may be decreased. PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: The US manufacturer of trientine states that mineral supplements should not be given with trientine. If concomitant therapy is necessary, take trientine on an empty stomach and separate administration at least one hour apart from any other drug. Monitor clinical status for decreased effectiveness and adjust the trientine dose if necessary. DISCUSSION: Multivitamins with minerals may decrease trientine absorption so ensure patient is aware of the risks. |

Because interruption of therapy for Wilson disease during pregnancy has resulted in acute liver failure, the American Association for the Study of Liver Diseases (AASLD) states that treatment should be continued during pregnancy. Although clinical experience is limited, use of trientine during pregnancy has been associated with successful outcomes for both mother and fetus. TheAASLD recommends that thedosage of trientine hydrochloride be reduced to the minimum necessary dosage during pregnancy, particularly during the third trimester, to promote better wound healing if cesarean section is performed. A dosage reduction of 25-50% of the pre-pregnancy dosage has been recommended with frequent monitoring of the patient.
The AASLD suggests that all medications used to treat Wilson disease are excreted into breast milk and generallyrecommends against use of these agents in nursing women due to the risk of causing copper deficiency in the infant.
The manufacturer makes no specific dosage recommendations for geriatric patients. Use caution and initiate treatmentat the lower end of the dosing range in geriatric patients. Clinical studies of trientine did not include sufficient numbers of patients 65 years of age and older to determine whether geriatric patients respond differently than younger patients. Use trientine withcaution and initiate treatment at the lower end of the dosing range in geriatric patients.
