Campral

Overview

What is Campral?

Campral (acamprosate calcium) is supplied in an enteric-coated tablet for oral administration. Acamprosate calcium is a synthetic compound with a chemical structure similar to that of the endogenous amino acid homotaurine, which is a structural analogue of the amino acid neurotransmitter γ-aminobutyric acid and the amino acid neuromodulator taurine. Its chemical name is calcium acetylaminopropane sulfonate. Its chemical formula is C H N O S Ca and molecular weight is 400.48. Its structural formula is:

Acamprosate calcium is a white, odorless or nearly odorless powder. It is freely soluble in water, and practically insoluble in absolute ethanol and dichloromethane.

Each Campral tablet contains acamprosate calcium 333 mg, equivalent to 300 mg of acamprosate. Inactive ingredients in Campral tablets include: crospovidone, microcrystalline cellulose, magnesium silicate, sodium starch glycolate, colloidal anhydrous silica, magnesium stearate, talc, propylene glycol and Eudragit L 30 D or equivalent. Sulfites were used in the synthesis of the drug substance and traces of residual sulfites may be present in the drug product.

What should I talk to my health care provider before I take Campral?

How should I use Campral?

Campral® is indicated for the maintenance of abstinence from alcohol in patients with alcohol dependence who are abstinent at treatment initiation. Treatment with Campral should be part of a comprehensive management program that includes psychosocial support.

The efficacy of Campral in promoting abstinence has not been demonstrated in subjects who have not undergone detoxification and not achieved alcohol abstinence prior to beginning Campral treatment. The efficacy of Campral in promoting abstinence from alcohol in polysubstance abusers has not been adequately assessed.

The recommended dose of Campral is two 333 mg tablets (each dose should total 666 mg) taken three times daily. A lower dose may be effective in some patients.

Although dosing may be done without regard to meals, dosing with meals was employed during clinical trials and is suggested in those patients who regularly eat three meals daily.

Treatment with Campral should be initiated as soon as possible after the period of alcohol withdrawal, when the patient has achieved abstinence, and should be maintained if the patient relapses. Campral should be used as part of a comprehensive psychosocial treatment program.

What should I look out for while using Campral?

Campral is contraindicated in patients who previously have exhibited hypersensitivity to acamprosate calcium or any of its components ( ).

Campral is contraindicated in patients with severe renal impairment ( ).


What might happen if I take too much Campral?

In all reported cases of acute overdosage with Campral (total reported doses of up to 56 grams of acamprosate calcium), the only symptom that could be reasonably associated with Campral was diarrhea. Hypercalcemia has not been reported in cases of acute overdose. A risk of hypercalcemia should be considered in chronic overdosage only. Treatment of overdose should be symptomatic and supportive.


How should I store and handle Campral?

Store at 20° to 25°C (68° to 77°F) [see USP Controlled Room Temperature]. Protect from light. NDC:68151-4760-0 in a PACKAGE of 1 TABLET, DELAYED RELEASES

Clinical Information

Chemical Structure

Clinical Pharmacology

The mechanism of action of acamprosate in maintenance of alcohol abstinence is not completely understood. Chronic alcohol exposure is hypothesized to alter the normal balance between neuronal excitation and inhibition. and studies in animals have provided evidence to suggest acamprosate may interact with glutamate and GABA neurotransmitter systems centrally, and has led to the hypothesis that acamprosate restores this balance.

Non-Clinical Toxicology
Campral is contraindicated in patients who previously have exhibited hypersensitivity to acamprosate calcium or any of its components ( ).

Campral is contraindicated in patients with severe renal impairment ( ).

If phenytoin or other hepatic enzyme inducers are taken concurrently with Disopyramide Phosphate, lower plasma levels of disopyramide may occur. Monitoring of disopyramide plasma levels is recommended in such concurrent use to avoid ineffective therapy. Other antiarrhythmic drugs (e.g., quinidine, procainamide, lidocaine, propranolol) have occasionally been used concurrently with Disopyramide Phosphate. Excessive widening of the QRS complex and/or prolongation of the Q-T interval may occur in these situations (see ). In healthy subjects, no significant drug-drug interaction was observed when Disopyramide Phosphate was coadministered with either propranolol or diazepam. Concomitant administration of Disopyramide Phosphate and quinidine resulted in slight increases in plasma disopyramide levels and slight decreases in plasma quinidine levels. Disopyramide Phosphate does not increase serum digoxin levels.

Until data on possible interactions between verapamil and disopyramide phosphate are obtained, disopyramide should not be administered within 48 hours before or 24 hours after verapamil administration.

Although potent inhibitors of cytochrome P450 3A4 (e.g., ketoconazole) have not been studied clinically, studies have shown that erythromycin and oleandomycin inhibit the metabolism of disopyramide. Cases of life-threatening interactions have been reported for disopyramide when given with clarithromycin and erythromycin indicating that coadministration of disopyramide with inhibitors of cytochrome P450 3A4 could result in potentially fatal interaction.

Treatment with Campral in patients with moderate renal impairment (creatinine clearance of 30-50 mL/min) requires a dose reduction [ ]. Campral is contraindicated in patients with severe renal impairment (creatinine clearance of ≤30 mL/min) [ and ].
