Overview

Trientine is a Adrenergic receptor agonist that is FDA approved for the treatment of a list of indications, separated by commas.. Common adverse reactions include {{{adverseReactions}}}.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Indications

SYPRINE is indicated in the treatment of patients with Wilson's disease who are intolerant of penicillamine. Clinical experience with SYPRINE is limited and alternate dosing regimens have not been well-characterized; all endpoints in determining an individual patient's dose have not been well defined. SYPRINE and penicillamine cannot be considered interchangeable. SYPRINE should be used when continued treatment with penicillamine is no longer possible because of intolerable or life endangering side effects.

Unlike penicillamine, SYPRINE is not recommended in cystinuria or rheumatoid arthritis. The absence of a sulfhydryl moiety renders it incapable of binding cystine and, therefore, it is of no use in cystinuria. In 15 patients with rheumatoid arthritis, SYPRINE was reported not to be effective in improving any clinical or biochemical parameter after 12 weeks of treatment.

SYPRINE is not indicated for treatment of biliary cirrhosis.

Dosage

Systemic evaluation of dose and/or interval between dose has not been done. However, on limited clinical experience, the recommended initial dose of SYPRINE is 500-750 mg/day for pediatric patients and 750-1250 mg/day for adults given in divided doses two, three or four times daily. This may be increased to a maximum of 2000 mg/day for adults or 1500 mg/day for pediatric patients age 12 or under.

The daily dose of SYPRINE should be increased only when the clinical response is not adequate or the concentration of free serum copper is persistently above 20 mcg/dL. Optimal long-term maintenance dosage should be determined at 6-12 month intervals.

It is important that SYPRINE be given on an empty stomach, at least one hour before meals or two hours after meals and at least one hour apart from any other drug, food, or milk. The capsules should be swallowed whole with water and should not be opened or chewed.

Warnings

Patient experience with trientine hydrochloride is limited. Patients receiving SYPRINE should remain under regular medical supervision throughout the period of drug administration. Patients (especially women) should be closely monitored for evidence of iron deficiency anemia.

Adverse Reactions

Clinical Trials Experience

Clinical experience with SYPRINE has been limited. The following adverse reactions have been reported in a clinical study in patients with Wilson's disease who were on therapy with trientine hydrochloride: iron deficiency, systemic lupus erythematosus. In addition, the following adverse reactions have been reported in marketed use: dystonia, muscular spasm, myasthenia gravis.

SYPRINE is not indicated for treatment of biliary cirrhosis, but in one study of 4 patients treated with trientine hydrochloride for primary biliary cirrhosis, the following adverse reactions were reported: heartburn; epigastric pain and tenderness; thickening, fissuring and flaking of the skin; hypochromic microcytic anemia; acute gastritis; aphthoid ulcers; abdominal pain; melena; anorexia; malaise; cramps; muscle pain; weakness; rhabdomyolysis. A causal relationship of these reactions to drug therapy could not be rejected or established.

Postmarketing Experience

There is limited information regarding Trientine Postmarketing Experience in the drug label.

Drug Interactions

In general, mineral supplements should not be given since they may block the absorption of SYPRINE. However, iron deficiency may develop, especially in children and menstruating or pregnant women, or as a result of the low copper diet recommended for Wilson's disease. If necessary, iron may be given in short courses, but since iron and SYPRINE each inhibit absorption of the other, two hours should elapse between administration of SYPRINE and iron.

It is important that SYPRINE be taken on an empty stomach, at least one hour before meals or two hours after meals and at least one hour apart from any other drug, food, or milk. This permits maximum absorption and reduces the likelihood of inactivation of the drug by metal binding in the gastrointestinal tract.

Use in Specific Populations

Pregnancy

Pregnancy Category (FDA): Pregnancy Category C

Trientine hydrochloride was teratogenic in rats at doses similar to the human dose. The frequencies of both resorptions and fetal abnormalities, including hemorrhage and edema, increased while fetal copper levels decreased when trientine hydrochloride was given in the maternal diets of rats. There are no adequate and well-controlled studies in pregnant women. SYPRINE should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Pregnancy Category (AUS): There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Trientine in women who are pregnant.

Labor and Delivery

There is no FDA guidance on use of Trientine during labor and delivery.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when SYPRINE is administered to a nursing mother.

Pediatric Use

Controlled studies of the safety and effectiveness of SYPRINE in pediatric patients have not been conducted. It has been used clinically in pediatric patients as young as 6 years with no reported adverse experiences.

Geriatic Use

Clinical studies of SYPRINE did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience is insufficient to determine differences in responses between the elderly and younger patients. In general, dose selection should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.

Gender

There is no FDA guidance on the use of Trientine with respect to specific gender populations.

Race

There is no FDA guidance on the use of Trientine with respect to specific racial populations.

Renal Impairment

There is no FDA guidance on the use of Trientine in patients with renal impairment.

Hepatic Impairment

There is no FDA guidance on the use of Trientine in patients with hepatic impairment.

Females of Reproductive Potential and Males

There is no FDA guidance on the use of Trientine in women of reproductive potentials and males.

Immunocompromised Patients

There is no FDA guidance one the use of Trientine in patients who are immunocompromised.
