INDICATIONS AND USAGE:

Vero-Pyrazinamide is indicated for the initial treatment of active tuberculosis in adults and children when combined with other antituberculous agents. (The current recommendation of the CDC for drug-susceptible disease is to use a six-month regimen for initial treatment of active tuberculosis, consisting of isoniazid, rifampin and Vero-Pyrazinamide given for 2 months, followed by isoniazid and rifampin for 4 months.^*4)

(Patients with drug-resistant disease should be treated with regimens individualized to their situation. Vero-Pyrazinamide frequently will be an important component of such therapy.)

(In patients with concomitant HIV infection, the physician should be aware of current recommendation of CDC. It is possible these patients may require a longer course of treatment).

It is also indicated after treatment failure with other primary drugs in any form of active tuberculosis.

Vero-Pyrazinamide should only be used in conjunction with other effective antituberculous agents.

*See recommendations of Center for Disease Control (CDC) and American Thoracic Society for complete regimen and dosage recommendations.⁴

CONTRAINDICATIONS:

Vero-Pyrazinamide is contraindicated in persons:

with severe hepatic damage.
who have shown hypersensitivity to it.
with acute gout.

WARNINGS:

Patients started on Vero-Pyrazinamide should have baseline serum uric acid and liver function determinations. Those patients with preexisting liver disease or those at increased risk for drug related hepatitis (e.g., alcohol abusers) should be followed closely.

Vero-Pyrazinamide should be discontinued and not be resumed if signs of hepatocellular damage or hyperuricemia accompanied by an acute gouty arthritis appear.

PRECAUTIONS:

General:

Vero-Pyrazinamide inhibits renal excretion of urates, frequently resulting in hyperuricemia which is usually asymptomatic. If hyperuricemia is accompanied by acute gouty arthritis, Vero-Pyrazinamide should be discontinued.

Vero-Pyrazinamide should be used with caution in patients with a history of diabetes mellitus, as management may be more difficult.

Primary resistance of M. tuberculosis to Vero-Pyrazinamide is uncommon. In cases with known or suspected drug resistance, in vitro susceptibility tests with recent cultures of M. tuberculosis against Vero-Pyrazinamide and the usual primary drugs should be performed. There are few reliable in vitro tests for Vero-Pyrazinamide resistance. A reference laboratory capable of performing these studies must be employed.

Information for Patients:

Patients should be instructed to notify their physicians promptly if they experience any of the following: fever, loss of appetite, malaise, nausea and vomiting, darkened urine, yellowish discoloration of the skin and eyes, pain or swelling of the joints.

Compliance with the full course of therapy must be emphasized, and the importance of not missing any doses must be stressed.

Laboratory Tests:

Baseline liver function studies [especially ALT, AST (SGOT) determinations] and uric acid levels should be determined prior to therapy. Appropriate laboratory testing should be performed at periodic intervals and if any clinical signs of symptoms occur during therapy.

Drug/Laboratory Test Interactions:

Vero-Pyrazinamide has been reported to interfere with ACETEST^® and KETOSTIX^® urine tests to produce a pink-brown color.⁵

Carcinogenesis, Mutagenesis, Impairment of Fertility:^6,7,8

In lifetime bioassays in rats and mice, Vero-Pyrazinamide was administered in the diet at concentrations of up to 10,000 ppm. This resulted in estimated daily doses for the mouse of 2 g/kg, or 40 times the maximum human dose, and for the rat of 0.5 g/kg, or 10 times the maximum human dose. Vero-Pyrazinamide was not carcinogenic in rats or male mice and no conclusion was possible for female mice due to insufficient numbers of surviving control mice.

Vero-Pyrazinamide was not mutagenic in the Ames bacterial test, but induced chromosomal aberrations in human lymphocyte cell cultures.

Pregnancy:

Teratogenic Effects-Pregnancy Category C

Animal reproduction studies have not been conducted with Vero-Pyrazinamide. It is also not known whether Vero-Pyrazinamide can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Vero-Pyrazinamide should be given to a pregnant woman only if clearly needed.

Nursing Mothers:

Vero-Pyrazinamide has been found in small amounts in breast milk. Therefore, it is advised that Vero-Pyrazinamide be used with caution in nursing mothers taking into account the risk-benefit of this therapy.⁹

Pediatric Use:

Vero-Pyrazinamide regimens employed in adults are probably equally effective in pediatric patients.^4,10,11 Vero-Pyrazinamide appears to be well tolerated in pediatric patients.

Geriatric Use:¹²

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

It does not appear that patients with impaired renal function require a reduction in dose. It may be prudent to select doses at the low end of the dosing range, however.¹³

ADVERSE REACTIONS:

General:

Fever, porphyria and dysuria have rarely been reported. Gout.

Gastrointestinal:

The principal adverse effect is a hepatic reaction. Hepatotoxicity appears to be dose related, and may appear at any time during therapy. GI disturbances including nausea, vomiting and anorexia have also been reported.

Hematologic and Lymphatic:

Thrombocytopenia and sideroblastic anemia with erythroid hyperplasia, vacuolation of erythrocytes and increased serum iron concentration have occurred rarely with this drug. Adverse effects on blood clotting mechanisms have also been rarely reported.

Other:

Mild arthralgia and myalgia have been reported frequently. Hypersensitivity reactions including rashes, urticaria, and pruritis have been reported. Fever, acne, photosensitivity, porphyria, dysuria and interstitial nephritis have been reported rarely.

OVERDOSAGE:

Overdosage experience is limited. In one case report of overdose, abnormal liver function tests developed. These spontaneously reverted to normal when the drug was stopped. Clinical monitoring and supportive therapy should be employed. Vero-Pyrazinamide is dialyzable.¹³

DOSAGE AND ADMINISTRATION:

Vero-Pyrazinamide should always be administered with other effective antituberculous drugs. It is administered for the initial 2 months of a 6-month or longer treatment regimen for drug-susceptible patients. Patients who are known or suspected to have drug-resistant disease should be treated with regimens individualized to their situation.

Vero-Pyrazinamide frequently will be an important component of such therapy.

Patients with concomitant HIV infection may require longer courses of therapy. Physicians treating such patients should be alert to any revised recommendations from CDC for this group of patients.

Usual dose: Vero-Pyrazinamide is administered orally, 15 to 30 mg/kg once daily. Older regimens employed 3 or 4 divided doses daily, but most current recommendations are for once a day. Three grams per day should not be exceeded. The CDC recommendations do not exceed 2 g per day when given as a daily regimen.

Alternatively, a twice weekly dosing regimen (50 to 75 mg/kg twice weekly based on lean body weight) has been developed to promote patient compliance with a regimen on an outpatient basis. In studies evaluation the twice weekly regimen, doses of Vero-Pyrazinamide in excess of 3 g twice weekly have been administered. This exceeds the recommended maximum 3 g/daily dose. However, an increased incidence of adverse reactions has not been reported.

This table is taken from the CDC-American Thoracic Society joint recommendations.⁴
