Indication(s)

INDICATIONS CUPRIMINE is indicated in the treatment of Wilson 's disease, cystinuria, and in patients with severe, active rheumatoid arthritis who have failed to respond to an adequate trial of conventional therapy.

Available evidence suggests that CUPRIMINE is not of value in ankylosing spondylitis.

Wilson 's Disease Wilson 's disease (hepatolenticular degeneration) occurs in individuals who have inherited an autosomal recessive defect that leads to an accumulation of copper far in excess of metabolic requirements.

The excess copper is deposited in several organs and tissues, and eventually produces pathological effects primarily in the liver, where damage progresses to postnecrotic cirrhosis, and in the brain, where degeneration is widespread.

Copper is also deposited as characteristic, asymptomatic, golden-brown Kayser-Fleischer rings in the corneas of all patients with cerebral symptomatology and some patients who are either asymptomatic or manifest only hepatic symptomatology.

Two types of patients require treatment for Wilson 's disease: (1) the symptomatic, and (2) the asymptomatic in whom it can be assumed the disease will develop in the future if the patient is not treated.

The diagnosis, if suspected on the basis of family or individual history or physical examination, can be confirmed if the plasma copper-protein ceruloplasminFor quantitative test for serum ceruloplasmin see: Morell, A.G.; Windsor, J.; Sternlieb, I.; Scheinberg, I.H.: Measurement of the concentration of ceruloplasmin in serum by determination of its oxidase activity, in " Laboratory Diagnosis of Liver Disease ", F.W. Sunderman; F.W. Sunderman, Jr. (eds.), St. Louis, Warren H. Green, Inc., 1968, pp. 193-195.

is <20 mg/dL and either a quantitative determination in a liver biopsy specimen shows an abnormally high concentration of copper (>250 mcg/ g dry weight) or Kayser-Fleischer rings are present.

Treatment has two objectives: 1)to minimize dietary intake of copper; 2)to promote excretion and complex formation (i.e., detoxification) of excess tissue copper.

The first objective is attained by a daily diet that contains no more than one or two milligrams of copper.

Such a diet should exclude, most importantly, chocolate, nuts, shellfish, mushrooms, liver, molasses, broccoli, and cereals and dietary supplements enriched with copper, and be composed to as great an extent as possible of foods with a low copper content.

Distilled or demineralized water should be used if the patient 's drinking water contains more than 0.1 mg of copper per liter.

For the second objective, a copper chelating agent is used.

In symptomatic patients this treatment usually produces marked neurologic improvement, fading of Kayser-Fleischer rings, and gradual amelioration of hepatic dysfunction and psychic disturbances.

Clinical experience to date suggests that life is prolonged with the above regimen.

Noticeable improvement may not occur for one to three months.

Occasionally, neurologic symptoms become worse during initiation of therapy with CUPRIMINE. Despite this, the drug should not be withdrawn.

Temporary interruption carries an increased risk of developing a sensitivity reaction upon resumption of therapy, although it may result in clinical improvement of neurological symptoms (see WARNINGS).

If the neurological symptoms and signs continue to worsen for a month after the initiation of CUPRIMINE therapy, several short courses of treatment with 2, 3 - dimercaprol (BAL) while continuing CUPRIMINE may be considered.

Treatment of asymptomatic patients has been carried out for over thirty years.

Symptoms and signs of the disease appear to be prevented indefinitely if daily treatment with CUPRIMINE is continued.

Cystinuria Cystinuria is characterized by excessive urinary excretion of the dibasic amino acids, arginine, lysine, ornithine, and cystine, and the mixed disulfide of cysteine and homocysteine.

The metabolic defect that leads to cystinuria is inherited as an autosomal, recessive trait.

Metabolism of the affected amino acids is influenced by at least two abnormal factors: (1) defective gastrointestinal absorption and (2) renal tubular dysfunction.

Arginine, lysine, ornithine, and cysteine are soluble substances, readily excreted.

There is no apparent pathology connected with their excretion in excessive quantities.

Cystine, however, is so slightly soluble at the usual range of urinary pH that it is not excreted readily, and so crystallizes and forms stones in the urinary tract.

Stone formation is the only known pathology in cystinuria.

Normal daily output of cystine is 40 to 80 mg.

In cystinuria, output is greatly increased and may exceed 1 g/day.

At 500 to 600 mg/day, stone formation is almost certain.

When it is more than 300 mg/day, treatment is indicated.

Conventional treatment is directed at keeping urinary cystine diluted enough to prevent stone formation, keeping the urine alkaline enough to dissolve as much cystine as possible, and minimizing cystine production by a diet low in methionine (the major dietary precursor of cystine).

Patients must drink enough fluid to keep urine specific gravity below 1.010, take enough alkali to keep urinary pH at 7.5 to 8, and maintain a diet low in methionine.

This diet is not recommended in growing children and probably is contraindicated in pregnancy because of its low protein content (see PRECAUTIONS).

When these measures are inadequate to control recurrent stone formation, CUPRIMINE may be used as additional therapy, and when patients refuse to adhere to conventional treatment, CUPRIMINE may be a useful substitute.

It is capable of keeping cystine excretion to near normal values, thereby hindering stone formation and the serious consequences of pyelonephritis and impaired renal function that develop in some patients.

Bartter and colleagues depict the process by which penicillamine interacts with cystine to form penicillamine-cysteine mixed disulfide as: CSSC + PS ' CS ' + CSSP PSSP + CS '

PS ' + CSSP CSSC + PSSP' 2CSSP CSSC = cystine CS ' = deprotonated cysteine PSSP = penicillamine disulfide PS ' = deprotonated penicillamine sulfhydryl CSSP = penicillamine-cysteine mixed disulfide In this process, it is assumed that the deprotonated form of penicillamine, PS ', is the active factor in bringing about the disulfide interchange.

Figure Figure Figure Rheumatoid Arthritis Because CUPRIMINE can cause severe adverse reactions, its use in rheumatoid arthritis should be restricted to patients who have severe, active disease and who have failed to respond to an adequate trial of conventional therapy.

Even then, benefit-to-risk ratio should be carefully considered.

Other measures, such as rest, physiotherapy, salicylates, and corticosteroids should be used, when indicated, in conjunction with CUPRIMINE (see PRECAUTIONS).

Advisory information

contraindications

CONTRAINDICATIONS Except for the treatment of Wilson 's disease or certain patients with cystinuria, use of penicillamine during pregnancy is contraindicated (see WARNINGS).

Although breast milk studies have not been reported in animals or humans, mothers on therapy with penicillamine should not nurse their infants.

Patients with a history of penicillamine-related aplastic anemia or agranulocytosis should not be restarted on penicillamine (see WARNINGS and ADVERSE REACTIONS).

Because of its potential for causing renal damage, penicillamine should not be administered to rheumatoid arthritis patients with a history or other evidence of renal insufficiency.

Special warnings and precautions

PRECAUTIONS Some patients may experience drug fever, a marked febrile response to penicillamine, usually in the second to third week following initiation of therapy.

Drug fever may sometimes be accompanied by a macular cutaneous eruption.

In the case of drug fever in patients with Wilson 's disease or cystinuria, penicillamine should be temporarily discontinued until the reaction subsides.

Then penicillamine should be reinstituted with a small dose that is gradually increased until the desired dosage is attained.

Systemic steroid therapy may be necessary, and is usually helpful, in such patients in whom drug fever and rash develop several times.

In the case of drug fever in rheumatoid arthritis patients, because other treatments are available, penicillamine should be discontinued and another therapeutic alternative tried since experience indicates that the febrile reaction will recur in a very high percentage of patients upon readministration of penicillamine.

The skin and mucous membranes should be observed for allergic reactions.

Early and late rashes have occurred.

Early rash occurs during the first few months of treatment and is more common.

It is usually a generalized pruritic, erythematous, maculopapular or morbilliform rash and resembles the allergic rash seen with other drugs.

Early rash usually disappears within days after stopping penicillamine and seldom recurs when the drug is restarted at a lower dosage.

Pruritus and early rash may often be controlled by the concomitant administration of antihistamines.

Less commonly, a late rash may be seen, usually after six months or more of treatment, and requires discontinuation of penicillamine.

It is usually on the trunk, is accompanied by intense pruritus, and is usually unresponsive to topical corticosteroid therapy.

Late rash may take weeks to disappear after penicillamine is stopped and usually recurs if the drug is restarted.

The appearance of a drug eruption accompanied by fever, arthralgia, lymphadenopathy or other allergic manifestations usually requires discontinuation of penicillamine.

Certain patients will develop a positive antinuclear antibody (ANA) test and some of these may show a lupus erythematosus-like syndrome similar to drug-induced lupus associated with other drugs.

The lupus erythematosus-like syndrome is not associated with hypocomplementemia and may be present without nephropathy.

The development of a positive ANA test does not mandate discontinuance of the drug; however, the physician should be alerted to the possibility that a lupus erythematosus-like syndrome may develop in the future.

Some patients may develop oral ulcerations which in some cases have the appearance of aphthous stomatitis.

The stomatitis usually recurs on rechallenge but often clears on a lower dosage.

Although rare, cheilosis, glossitis and gingivostomatitis have also been reported.

These oral lesions are frequently dose-related and may preclude further increase in penicillamine dosage or require discontinuation of the drug.

Hypogeusia (a blunting or diminution in taste perception) has occurred in some patients.

This may last two to three months or more and may develop into a total loss of taste; however, it is usually self-limited despite continued penicillamine treatment.

Such taste impairment is rare in patients with Wilson 's disease.

Penicillamine should not be used in patients who are receiving concurrently gold therapy, antimalarial or cytotoxic drugs, oxyphenbutazone or phenylbutazone because these drugs are also associated with similar serious hematologic and renal adverse reactions.

Patients who have had gold salt therapy discontinued due to a major toxic reaction may be at greater risk of serious adverse reactions with penicillamine but not necessarily of the same type.

Patients who are allergic to penicillin may theoretically have cross-sensitivity to penicillamine.

The possibility of reactions from contamination of penicillamine by trace amounts of penicillin has been eliminated now that penicillamine is being produced synthetically rather than as a degradation product of penicillin.

Patients with Wilson 's disease or cystinuria should be given 25 mg/day of pyridoxine during therapy, since penicillamine increases the requirement for this vitamin.

Patients also may receive benefit from a multivitamin preparation, although there is no evidence that deficiency of any vitamin other than pyridoxine is associated with penicillamine.

In Wilson 's disease, multivitamin preparations must be copper-free.

Rheumatoid arthritis patients whose nutrition is impaired should also be given a daily supplement of pyridoxine.

Mineral supplements should not be given, since they may block the response to penicillamine.

Iron deficiency may develop, especially in pediatric patients and in menstruating women.

In Wilson 's disease, this may be a result of adding the effects of the low copper diet, which is probably also low in iron, and the penicillamine to the effects of blood loss or growth.

In cystinuria, a low methionine diet may contribute to iron deficiency, since it is necessarily low in protein.

If necessary, iron may be given in short courses, but a period of two hours should elapse between administration of penicillamine and iron, since orally administered iron has been shown to reduce the effects of penicillamine.

Penicillamine causes an increase in the amount of soluble collagen.

In the rat this results in inhibition of normal healing and also a decrease in tensile strength of intact skin.

In man this may be the cause of increased skin friability at sites especially subject to pressure or trauma, such as shoulders, elbows, knees, toes, and buttocks.

Extravasations of blood may occur and may appear as purpuric areas, with external bleeding if the skin is broken, or as vesicles containing dark blood.

Neither type is progressive.

There is no apparent association with bleeding elsewhere in the body and no associated coagulation defect has been found.

Therapy with penicillamine may be continued in the presence of these lesions.

They may not recur if dosage is reduced.

Other reported effects probably due to the action of penicillamine on collagen are excessive wrinkling of the skin and development of small, white papules at venipuncture and surgical sites.

The effects of penicillamine on collagen and elastin make it advisable to consider a reduction in dosage to 250 mg/day, when surgery is contemplated.

Reinstitution of full therapy should be delayed until wound healing is complete.

Carcinogenesis, Mutagenesis, Impairment of Fertility Long-term animal carcinogenicity studies have not been done with penicillamine.

There is a report that five of ten autoimmune disease-prone NZB hybrid mice developed lymphocytic leukemia after 6 months ' intraperitoneal treatment with a dose of 400 mg/kg penicillamine 5 days per week.

Penicillamine is directly mutagenic to S. typhimurium strain TA92 in the Ames test; mutagenicity is enhanced by kidney postmitochondrial subcellular fraction 9.

Penicillamine does not induce gene mutations in Chinese hamster V79 cells.

Penicillamine induces sister-chromatid exchanges and chromosome aberrations in cultivated mammalian cells.

No studies on the effect of penicillamine on fertility are available.

Pregnancy Pregnancy Category D (see WARNINGS, Pregnancy) Nursing Mothers See CONTRAINDICATIONS. Pediatric Use The efficacy of CUPRIMINE in juvenile rheumatoid arthritis has not been established.

Geriatric Use Clinical studies of CUPRIMINE are limited in subjects aged 65 and over; they did not include sufficient numbers of elderly subjects aged 65 and over to adequately determine whether they respond differently from younger subjects.

Review of reported clinical trials with penicillamine in the elderly suggest greater risk than in younger patients for overall skin rash and abnormality of taste.

In general, dose selection for an elderly patient should be cautious, 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 drugs.

This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function.

Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and careful monitoring of renal function is recommended.

Adverse reactions

ADVERSE REACTIONS Penicillamine is a drug with a high incidence of untoward reactions, some of which are potentially fatal.

Therefore, it is mandatory that patients receiving penicillamine therapy remain under close medical supervision throughout the period of drug administration (see WARNINGS and PRECAUTIONS).

Reported incidences (%) for the most commonly occurring adverse reactions in rheumatoid arthritis patients are noted, based on 17 representative clinical trials reported in the literature (1270 patients).

Allergic Generalized pruritus, early and late rashes (5 %), pemphigus (see WARNINGS), and drug eruptions which may be accompanied by fever, arthralgia, or lymphadenopathy have occurred (see WARNINGS and PRECAUTIONS).

Some patients may show a lupus erythematosus-like syndrome similar to drug-induced lupus produced by other pharmacological agents (see PRECAUTIONS).

Urticaria and exfoliative dermatitis have occurred.

Thyroiditis has been reported; hypoglycemia in association with anti-insulin antibodies has been reported.

These reactions are extremely rare.

Some patients may develop a migratory polyarthralgia, often with objective synovitis (see DOSAGE AND ADMINISTRATION).

Gastrointestinal Anorexia, epigastric pain, nausea, vomiting, or occasional diarrhea may occur (17 %).

Isolated cases of reactivated peptic ulcer have occurred, as have hepatic dysfunction including hepatic failure, and pancreatitis.

Intrahepatic cholestasis and toxic hepatitis have been reported rarely.

There have been a few reports of increased serum alkaline phosphatase, lactic dehydrogenase, and positive cephalin flocculation and thymol turbidity tests.

Some patients may report a blunting, diminution, or total loss of taste perception (12 %); or may develop oral ulcerations.

Although rare, cheilosis, glossitis, and gingivostomatitis have been reported (see PRECAUTIONS).

Gastrointestinal side effects are usually reversible following cessation of therapy.

Hematological Penicillamine can cause bone marrow depression (see WARNINGS).

Leukopenia (2 %) and thrombocytopenia (4 %) have occurred.

Fatalities have been reported as a result of thrombocytopenia, agranulocytosis, aplastic anemia, and sideroblastic anemia.

Thrombotic thrombocytopenic purpura, hemolytic anemia, red cell aplasia, monocytosis, leukocytosis, eosinophilia, and thrombocytosis have also been reported.

Renal Patients on penicillamine therapy may develop proteinuria (6 %) and/or hematuria which, in some, may progress to the development of the nephrotic syndrome as a result of an immune complex membranous glomerulopathy (see WARNINGS).

Renal failure has been reported.

Central Nervous System Tinnitus, optic neuritis and peripheral sensory and motor neuropathies (including polyradiculoneuropathy, i.e., Guillain-Barr?

syndrome) have been reported.

Muscular weakness may or may not occur with the peripheral neuropathies.

Visual and psychic disturbances; mental disorders; and agitation and anxiety have been reported.

Neuromuscular Myasthenia gravis (see WARNINGS); dystonia.

Other Adverse reactions that have been reported rarely include thrombophlebitis; hyperpyrexia (see PRECAUTIONS); falling hair or alopecia; lichen planus; polymyositis; dermatomyositis; mammary hyperplasia; elastosis perforans serpiginosa; toxic epidermal necrolysis; anetoderma (cutaneous macular atrophy); and Goodpasture 's syndrome, a severe and ultimately fatal glomerulonephritis associated with intra-alveolar hemorrhage (see WARNINGS).

Vasculitis, including fatal renal vasculitis, has also been reported.

Allergic alveolitis, obliterative bronchiolitis, interstitial pneumonitis and pulmonary fibrosis have been reported in patients with severe rheumatoid arthritis, some of whom were receiving penicillamine.

Bronchial asthma also has been reported.

Increased skin friability, excessive wrinkling of skin, and development of small white papules at venipuncture and surgical sites have been reported (see PRECAUTIONS); yellow nail syndrome.

The chelating action of the drug may cause increased excretion of other heavy metals such as zinc, mercury and lead.

There have been reports associating penicillamine with leukemia.

However, circumstances involved in these reports are such that a cause and effect relationship to the drug has not been established.

Usage information

Dosing and administration

DOSAGE AND ADMINISTRATION In all patients receiving penicillamine, it is important that CUPRIMINE 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.

Because penicillamine increases the requirement for pyridoxine, patients may require a daily supplement of pyridoxine (see PRECAUTIONS).

Wilson 's Disease Optimal dosage can be determined by measurement of urinary copper excretion and the determination of free copper in the serum.

The urine must be collected in copper-free glassware, and should be quantitatively analyzed for copper before and soon after initiation of therapy with CUPRIMINE. Determination of 24-hour urinary copper excretion is of greatest value in the first week of therapy with penicillamine.

In the absence of any drug reaction, a dose between 0.75 and 1.5 g that results in an initial 24-hour cupriuresis of over 2 mg should be continued for about three months, by which time the most reliable method of monitoring maintenance treatment is the determination of free copper in the serum.

This equals the difference between quantitatively determined total copper and ceruloplasmin-copper.

Adequately treated patients will usually have less than 10 mcg free copper/dL of serum.

It is seldom necessary to exceed a dosage of 2 g/day.

If the patient is intolerant to therapy with CUPRIMINE, alternative treatment is trientine hydrochloride.

In patients who can not tolerate as much as 1 g/day initially, initiating dosage with 250 mg/day, and increasing gradually to the requisite amount, gives closer control of the effects of the drug and may help to reduce the incidence of adverse reactions.

Cystinuria It is recommended that CUPRIMINE be used along with conventional therapy.

By reducing urinary cystine, it decreases crystalluria and stone formation.

In some instances, it has been reported to decrease the size of, and even to dissolve, stones already formed.

The usual dosage of CUPRIMINE in the treatment of cystinuria is 2 g/day for adults, with a range of 1 to 4 g/day.

For pediatric patients, dosage can be based on 30 mg/kg/day.

The total daily amount should be divided into four doses.

If four equal doses are not feasible, give the larger portion at bedtime.

If adverse reactions necessitate a reduction in dosage, it is important to retain the bedtime dose.

Initiating dosage with 250 mg/day, and increasing gradually to the requisite amount, gives closer control of the effects of the drug and may help to reduce the incidence of adverse reactions.

In addition to taking CUPRIMINE, patients should drink copiously.

It is especially important to drink about a pint of fluid at bedtime and another pint once during the night when urine is more concentrated and more acid than during the day.

The greater the fluid intake, the lower the required dosage of CUPRIMINE. Dosage must be individualized to an amount that limits cystine excretion to 100-200 mg/day in those with no history of stones, and below 100 mg/day in those who have had stone formation and/or pain.

Thus, in determining dosage, the inherent tubular defect, the patient 's size, age, and rate of growth, and his diet and water intake all must be taken into consideration.

The standard nitroprusside cyanide test has been reported useful as a qualitative measure of the effective dose:Lotz, M.; Potts, J.T. and Bartter, F.C.: Brit.

Med. J. 2: 521, Aug. 28, 1965 (in Medical Memoranda).

Add 2 mL of freshly prepared 5 percent sodium cyanide to 5 mL of a 24-hour aliquot of protein-free urine and let stand ten minutes.

Add 5 drops of freshly prepared 5 percent sodium nitroprusside and mix.

Cystine will turn the mixture magenta.

If the result is negative, it can be assumed that cystine excretion is less than 100 mg/g creatinine.

Although penicillamine is rarely excreted unchanged, it also will turn the mixture magenta.

If there is any question as to which substance is causing the reaction, a ferric chloride test can be done to eliminate doubt: Add 3 percent ferric chloride dropwise to the urine.

Penicillamine will turn the urine an immediate and quickly fading blue.

Cystine will not produce any change in appearance.

Rheumatoid Arthritis The principal rule of treatment with CUPRIMINE in rheumatoid arthritis is patience.

The onset of therapeutic response is typically delayed.

Two or three months may be required before the first evidence of a clinical response is noted (see CLINICAL PHARMACOLOGY).

When treatment with CUPRIMINE has been interrupted because of adverse reactions or other reasons, the drug should be reintroduced cautiously by starting with a lower dosage and increasing slowly.

Initial Therapy The currently recommended dosage regimen in rheumatoid arthritis begins with a single daily dose of 125 mg or 250 mg, which is thereafter increased at one to three month intervals, by 125 mg or 250 mg/day, as patient response and tolerance indicate.

If a satisfactory remission of symptoms is achieved, the dose associated with the remission should be continued (see Maintenance Therapy).

If there is no improvement and there are no signs of potentially serious toxicity after two to three months of treatment with doses of 500-750 mg/day, increases of 250 mg/day at two to three month intervals may be continued until a satisfactory remission occurs (see Maintenance Therapy) or signs of toxicity develop (see WARNINGS and PRECAUTIONS).

If there is no discernible improvement after three to four months of treatment with 1000 to 1500 mg of penicillamine/day, it may be assumed the patient will not respond and CUPRIMINE should be discontinued.

Maintenance Therapy The maintenance dosage of CUPRIMINE must be individualized, and may require adjustment during the course of treatment.

Many patients respond satisfactorily to a dosage within the 500-750 mg/day range.

Some need less.

Changes in maintenance dosage levels may not be reflected clinically or in the erythrocyte sedimentation rate for two to three months after each dosage adjustment.

Some patients will subsequently require an increase in the maintenance dosage to achieve maximal disease suppression.

In those patients who do respond, but who evidence incomplete suppression of their disease after the first six to nine months of treatment, the daily dosage of CUPRIMINE may be increased by 125 mg or 250 mg/day at three-month intervals.

It is unusual in current practice to employ a dosage in excess of 1 g/day, but up to 1.5 g/day has sometimes been required.

Management of Exacerbations During the course of treatment some patients may experience an exacerbation of disease activity following an initial good response.

These may be self-limited and can subside within twelve weeks.

They are usually controlled by the addition of non-steroidal anti-inflammatory drugs, and only if the patient has demonstrated a true " escape " phenomenon (as evidenced by failure of the flare to subside within this time period) should an increase in the maintenance dose ordinarily be considered.

In the rheumatoid patient, migratory polyarthralgia due to penicillamine is extremely difficult to differentiate from an exacerbation of the rheumatoid arthritis.

Discontinuance or a substantial reduction in dosage of CUPRIMINE for up to several weeks will usually determine which of these processes is responsible for the arthralgia.

Duration of Therapy The optimum duration of therapy with CUPRIMINE in rheumatoid arthritis has not been determined.

If the patient has been in remission for six months or more, a gradual, stepwise dosage reduction in decrements of 125 mg or 250 mg/day at approximately three month intervals may be attempted.

Concomitant Drug Therapy CUPRIMINE should not be used in patients who are receiving gold therapy, antimalarial or cytotoxic drugs, oxyphenbutazone, or phenylbutazone (see PRECAUTIONS).

Other measures, such as salicylates, other non-steroidal anti-inflammatory drugs, or systemic corticosteroids, may be continued when penicillamine is initiated.

After improvement commences, analgesic and anti-inflammatory drugs may be slowly discontinued as symptoms permit.

Steroid withdrawal must be done gradually, and many months of treatment with CUPRIMINE may be required before steroids can be completely eliminated.

Dosage Frequency Based on clinical experience, dosages up to 500 mg/day can be given as a single daily dose.

Dosages in excess of 500 mg/day should be administered in divided doses.
