Eurozina-RE

Induction and maintenance of remission of ulcerative colitis and treatment of active Crohn's disease.

The dose is adjusted according to the severity of the disease and the patient's tolerance of the drug, as detailed below.

A) Ulcerative Colitis

Adults and the Elderly

Severe attacks: 20 to 40 ml four times a day may be given in conjunction with steroids as part of an intensive management regime. Rapid passage of the suspension may reduce the effect of the drug.

The night time interval between doses should not exceed 8 hours.

Moderate attacks: 20 ml four times a day may be taken with or without steroids.

Maintenance therapy: With induction of remission, reduce the dose gradually to 40 ml per day. This dosage should be continued indefinitely, since discontinuance even several years after an acute attack is associated with a four-fold increase in relapse.

Children

The dose is reduced in proportion to body weight.

Acute attack or relapse: 0.8 - 1.2 ml/kg/day.

Maintenance dosage: 0.4 - 0.6 ml/kg/day.

B) Crohn's Disease

In active Crohn's Disease, Eurozina-REe should be administered as in attacks of ulcerative colitis (see above).

Eurozina-REe is contraindicated in:

- Infants under the age of two years.

- Patients with a known hypersensitivity to Eurozina-REe, its metabolites or any of the excipients as well as sulfonamides, salicylates or the sodium benzoate preservative.

- Patients with porphyria.

Complete blood counts, including differential white cell count and liver function tests, should be performed before starting Eurozina-REe, and every second week during the first three months of therapy. During the second three months, the same tests should be done once monthly and thereafter once every three months, and as clinically indicated. Assessment of renal function (including urinalysis) should be performed in all patients initially and at least monthly for the first three months of treatment. Thereafter, monitoring should be performed as clinically indicated.

The patient should also be counselled to report immediately with any sore throat, fever, malaise, pallor, purpura, jaundice or unexpected non-specific illness during Eurozina-REe treatment, this may indicate myelosuppression, haemolysis or hepatoxicity. Treatment should be stopped immediately while awaiting the results of blood tests.

Eurozina-REe should not be given to patients with impaired hepatic or renal function or with blood dyscrasias, unless the potential benefit outweighs the risk.

Eurozina-REe should be given with caution to patients with severe allergy or bronchial asthma.

Use in children with the concomitant condition systemic onset juvenile rheumatoid arthritis may result in a serum sickness like reaction; therefore Eurozina-REe is not recommended in these patients.

Since Eurozina-REe may cause haemolytic anaemia, it should be used with caution in patients with glucose-6-phosphate dehydrogenase deficiency.

Oral Eurozina-REe inhibits the absorption and metabolism of folic acid and may cause folic acid deficiency potentially resulting in serious blood disorders (e.g. macrocytosis and pancytopenia), this can be normalised by administration of folic acid or folinic acid (leucovorin).

Because Eurozina-REe causes crystalluria and kidney stone formation, adequate fluid intake should be ensured during treatment.

Oligospermia and infertility may occur in men treated with Eurozina-REe. Discontinuation of the drug appears to reverse these effects within 2 to 3 months.

Life-threatening cutaneous reactions Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported with the use of Eurozina-REe. Patients should be advised of the signs and symptoms and monitored closely for skin reactions. The highest risk for occurrence of SJS or TEN is within the first weeks of treatment. If symptoms or signs of SJS or TEN (e.g. progressive skin rash often with blisters or mucosal lesions) are present, Eurozina-REe treatment should be discontinued. The best results in managing SJS and TEN come from early diagnosis and immediate discontinuation of any suspect drug. Early withdrawal is associated with a better prognosis. If the patient has developed SJS or TEN with the use of Eurozina-REe, Eurozina-REe must not be re-started in this patient at any time.

Eurozina-REe may colour the urine orange-yellow.

Excipient warnings

This product contains small amounts of ethanol (alcohol), less than 100mg per 5ml.

No specific effects.

Overall, about 75% of ADRs occur within three months of treatment and over 90% by six months. Some unwanted effects are dose-dependent and symptoms can often be alleviated by reduction of the dose.

General

Eurozina-REe is split by intestinal bacteria to sulfapyridine and 5-amino salicylate so ADRs to either sulfonamide or salicylate are possible. Patients with slow acetylator status are more likely to experience ADRs related to sulfapyridine. The most commonly encountered ADRs are nausea, headache, rash, loss of appetite and raised temperature.

Eurozina-REe has beneficial effects in the treatment of ulcerative colitis and maintenance of remission, and in the treatment of acute Crohn's disease. Around 90% of a dose reaches the colon where bacteria split the drug into sulpyapyridine and mesalazine. These are active, and the unsplit Eurozina-REe is also active on a variety of systems. Most sulfapyridine is absorbed, hydroxylated or glucuronidated and a mix of unchanged and metabolised sulfapyridine appears in the urine. Some mesalazine is taken up and acetylated in the colon wall, such that renal excretion is mainly acetyl-mesalazine. Eurozina-REe is excreted unchanged in the bile and urine. Overall the drug and its metabolites exert immunomodulatory effects, antibacterial effects, effects on the arachidonic acid cascade and alteration of activity of certain enzymes. The net result clinically is a reduction in activity of the inflammatory bowel disease. The enteric coated Eurozina-REe is registered for the treatment of rheumatoid arthritis, where the effect resembles penicillamine or gold. Pharmacokinetic properties The information provided in Pharmacokinetic properties of Eurozina-RE is based on data of another medicine with exactly the same composition as the Eurozina-RE. . Be careful and be sure to specify the information on the section Pharmacokinetic properties in the instructions to the drug Eurozina-RE directly from the package or from the pharmacist at the pharmacy. more... With regard to the use of Eurozina-REe in bowel disease there is no evidence that systemic levels are of any relevance other than with regard to ADR incidence. Here levels of sulfapyridine over about 50µg/ml are associated with a substantial risk of ADRs, especially in slow acetylators. For Eurozina-REe given as a single 3g oral dose, peak serum levels of Eurozina-REe occurred in 3-5 hours, elimination half life was 5.7 ±0.7 hours, lag time 1.5 hours. During maintenance therapy renal clearance of Eurozina-REe was 7.3 ±1.7ml/min, for sulfapyridine 9.9 ±1.9 and acetyl-mesalazine 100 ±20. Free Eurozina-REe first appears in plasma in 4.3 hours after a single dose with an absorption half life of 2.7 hours. The elimination half life was calculated as 18 hours. For mesalazine, only acetyl-mesalazine (not free mesalazine) was demonstrable, the acetylation probably largely achieved in the colon mucosa. After 3g Eurozina-REe dose lag time was 6.1 ±2.3 hours and plasma levels kept below 2µg/ml total mesalazine. Urinary excretion half life was 6.0 ±3.1 hours and absorption half life based on these figures 3.0 ±1.5 hours. Renal clearance constant was 125 ml/min corresponding to the GFR. Studies in volunteers suggest that Eurozina-REe is handled in a similar manner whether given as suspension or tablets. Preclinical safety data The information provided in Preclinical safety data of Eurozina-RE is based on data of another medicine with exactly the same composition as the Eurozina-RE. . Be careful and be sure to specify the information on the section Preclinical safety data in the instructions to the drug Eurozina-RE directly from the package or from the pharmacist at the pharmacy. more... In two-year carcinogenicity studies in rats and mice, Eurozina-REe showed some evidence of carcinogenicity. In rats, there was a small increase in the incidence of transitional cell papillomas in the urinary bladder and kidney. The tumours were judged to be induced mechanically by calculi formed in the urine rather than through a direct genotoxic mechanism. In the mouse study, there was a significant increase in the incidence of hepatocellular adenoma or carcinoma. The mechanism of induction of hepatocellular neoplasia has been investigated and attributed to species-specific effects of Eurozina-REe that are not relevant to humans. Eurozina-REe did not show mutagenicity in the bacterial reverse mutation assay (Ames test) or in the L51784 mouse lymphoma cell assay at the HGPRT gene. It did not induce sister chromatid exchanges or chromosomal aberrations in cultured Chinese hamster ovary cells, and in vivo mouse bone marrow chromosomal aberration tests were negative. However, Eurozina-REe showed positive or equivocal mutagenic responses in rat and mouse micronucleus assays, and in human lymphocyte sister chromatid exchange, chromosomal aberration and micronucleus assays. The ability of Eurozina-REe to induce chromosome damage has been attributed to perturbation of folic acid levels rather than to a direct genotoxic mechanism. Based on information from non-clinical studies, Eurozina-REe is judged to pose no carcinogenic risk to humans. Eurozina-REe use has not been associated with the development of neoplasia in human epidemiology studies.
