Dosage

RESERVED FOR ADULTS AND CHILDREN WEIGHING MORE THAN 10KG.

PREDNISOLONE ZENTIVA 20 mg is suitable for initial treatments or short-term treatments requiring medium or high doses in adults and in children weighing more than 10 kg.

For maintenance treatment and for doses below 20 mg per day, more appropriate dosage strengths exist.

ADULT

The dosage varies depending on the diagnosis, the severity of the condition, the prognosis, the patient's response and tolerance to treatment.

Loading treatment : 0,35 to 1,2 mg/kg/day. For information only : 1 to 4 tablets per day in an adult weighing 60 kg.

During severe inflammatory diseases, the dose varies from 0,75 to 1,2 mg/kg/day. For reference: 2 to 4 tablets per day for an adult weighing 60 kg.

Some very exceptional situations may require higher doses.

Paediatric population

CHILDREN OVER 10 kg

The dosage must be adapted to the condition and to the child's weight.

Loading treatment : from 0,5 to 2 mg/kg/day. For information only : ½ to 2 tablets for a child of 20 kg.

Alternate-day corticosteroid therapy (one day without corticosteroid and the second day with a dose double the daily dose that would otherwise have been required) is used in children to try to limit growth retardation. This alternate-day regimen can only be considered after control of the inflammatory disease with high corticosteroid doses, and when no rebound is observed during tapering.

GENERAL

The "induction dose" treatment must be continued until the disease is durably controlled. In the case of long-term treatment, the dose reduction must be slow. Achieving withdrawal is the aim sought. Maintaining a maintenance dose (minimum effective dose) is a compromise that is sometimes necessary.

For prolonged treatment and high doses, the initial doses may be divided into two daily intakes. Subsequently, the daily dose may be administered as a single intake, preferably in the morning during a meal.

TREATMENT DISCONTINUATION

The pace of withdrawal depends mainly on the duration of treatment, the starting dose and the disease.

The treatment leads to suppression of ACTH and cortisol secretion, sometimes with lasting adrenal insufficiency. On withdrawal, discontinuation must be carried out gradually, in steps, because of the risk of relapse: reduction by 10% every 8 to 15 days on average.

For short courses of less than 10 days, stopping the treatment does not require tapering.

During dose tapering (prolonged course): at a dose of 5 to 7 mg prednisone equivalent, when the underlying disease no longer requires corticosteroid therapy, it is advisable to replace the synthetic corticosteroid with 20 mg/day of hydrocortisone until recovery of corticotropic function. If corticosteroid therapy must be maintained at a dose below 5 mg prednisone equivalent per day, a small dose of hydrocortisone may be added to reach a hydrocortisone equivalent of 20 to 30 mg per day. When the patient is only on hydrocortisone, the corticotropic axis can be tested by endocrine tests. These tests alone do not rule out the possibility of adrenal insufficiency occurring during stress.

Under hydrocortisone or even well after discontinuation, the patient must be told of the need to increase the usual dosage or resume replacement therapy (for example 100 mg of hydrocortisone intramuscularly every 6 to 8 hours) in case of stress: surgical intervention, trauma, infection.

Method of administration

Oral use.

Anti-inflammatory equivalence (equipotency) for 5 mg of prednisone: 5 mg of prednisolone.

The tablets are to be dissolved in a glass of water during the meal.

This medicine is generally contraindicated in the following situations (there is, however, no absolute contraindication to corticosteroid therapy for a vital indication):

• hypersensitivity to prednisolone or to any of the excipients listed in section Composition,

• any infectious state, with the exception of the specified indications (see section Indications),

• certain active viral infections (notably hepatitis, herpes, chickenpox, shingles),

• psychotic states not yet controlled by treatment,

• live vaccines.

Special warnings

In cases of gastroduodenal ulcer, corticosteroid therapy is not contraindicated if anti-ulcer treatment is given concurrently.

In case of a history of peptic ulcer, corticosteroid therapy may be prescribed, with clinical monitoring and, if necessary, after fibroscopy.

Corticosteroid therapy may promote the occurrence of various infectious complications, notably due to bacteria, yeasts and parasites. The occurrence of malignant strongyloidiasis is a significant risk. All subjects coming from an endemic area (tropical, subtropical regions, southern Europe) must have a stool parasitological examination and systematic eradication treatment before corticosteroid therapy.

Evolving signs of infection may be masked by corticosteroid therapy.

After prolonged use of prednisolone, a corticosteroid withdrawal syndrome may occur.

Discontinuation of corticosteroids after prolonged treatment must be done gradually. The risks associated with abrupt discontinuation of treatment are exacerbation or recurrence of the underlying disease, acute adrenal insufficiency (particularly in stressful situations, for example during infections, after an accident, during intense physical exertion) or corticosteroid withdrawal syndrome. Corticosteroid withdrawal syndrome may present with a set of symptoms, the most typical of which are fever, anorexia, nausea, lethargy, malaise, arthralgia, skin desquamation, asthenia, hypotension and weight loss.

Before starting treatment, it is important to rule out any possibility of a visceral focus, particularly tuberculosis, and to monitor during treatment for the onset of infectious pathologies.

In case of past tuberculosis, prophylactic anti-tuberculosis treatment is necessary if there are significant radiological sequelae and if one cannot ensure that a well-conducted treatment of 6 months with rifampicin has been given.

The use of corticosteroids requires particularly appropriate monitoring, notably in elderly subjects and in cases of ulcerative colitis (risk of perforation), recent intestinal anastomoses, renal insufficiency, hepatic insufficiency, osteoporosis, myasthenia gravis.

Due to the risk of growth retardation, prolonged use (and exposure to higher doses) of prednisolone should be avoided in children.

Oral or injectable corticosteroids may promote the occurrence of tendinopathy, or even tendon rupture (exceptional). This risk is increased when co-prescribed with fluoroquinolones and in dialysed patients with secondary hyperparathyroidism or who have undergone renal transplantation.

This medicinal product is not recommended in combination with anti-inflammatory doses of acetylsalicylic acid (see section Interactions).

Visual disorders : visual disturbances may occur during systemic or local corticotherapy. In case of blurred vision or onset of any other visual symptom during corticotherapy, an ophthalmological examination is required to look for, in particular, a cataract, glaucoma, or a rarer lesion such as central serous chorioretinopathy, described with the administration of systemic or local corticosteroids.

Crises related to the presence of a pheochromocytoma, which may be fatal, have been reported following administration of corticosteroids. Corticosteroids should only be administered to patients in whom a pheochromocytoma is suspected or identified after appropriate assessment of the benefit/risk ratio (see section Adverse effects).

Scleroderma renal crisis : precautions are required for patients suffering from systemic sclerosis, as an increased incidence of scleroderma renal crisis (which may be fatal) accompanied by hypertension and a decrease in urine output has been reported with the administration of a daily dose of 15 mg or more of prednisolone. Blood pressure and renal function (serum creatinine) should therefore be checked regularly. In case of suspected renal crisis, blood pressure must be carefully monitored.

Adrenal insufficiency

Secondary adrenocortical insufficiency may develop during treatment.

Glucocorticoid-induced suppression of the hypothalamic-pituitary-adrenal function depends on the dose and duration of treatment. Recovery occurs gradually as the steroid dose is reduced and discontinued. However, relative insufficiency may persist for months after treatment has been stopped; therefore, in any stress situation (for example during infections, after accidents, or in cases of increased physical exertion) treatment should be reinstated.

Since marketing, tumour lysis syndrome (TLS) has been reported in patients with malignant haemopathies following the use of PREDNISOLONE ZENTIVA 20 mg, scored effervescent tablet alone or in combination with other chemotherapy agents. Patients at high risk of TLS, such as patients with a high proliferation rate, high tumour burden and high sensitivity to cytotoxic agents, should be closely monitored and appropriate precautions should be taken (See section Adverse effects Adverse effects

Special precautions for use

This medicine must not be used in children weighing less than 10 kg and therefore in premature and full-term newborns (see section Dosage and administration.). However, hypertrophic cardiomyopathies have been reported after systemic administration of other glucocorticoids in premature infants. In infants treated with systemic glucocorticoids, cardiac ultrasounds must be performed to monitor myocardial structure and function.

In case of long-term treatment with corticosteroids

A diet low in rapidly absorbed sugars and high in protein should be combined, due to the hyperglycaemic effect and protein catabolism with negative nitrogen balance.

Fluid and sodium retention is common, partly responsible for a possible increase in blood pressure. This medicine contains sodium. This medicine contains 27 mg of sodium per tablet. To be taken into account in patients on a strict low-sodium diet. Sodium intake will be reduced for daily doses greater than 15 or 20 mg prednisone equivalent and moderated in long-term treatments at low doses.

Potassium supplementation is only justified for high-dose treatments, prescribed for a long duration, or in case of risk of rhythm disorders or association with a hypokalaemic treatment.

The patient must systematically have an intake of calcium and vitamin D.

When corticosteroid therapy is essential, diabetes and arterial hypertension are not contraindications, but the treatment may cause their imbalance. Their management should be reassessed.

Certain viral diseases (chickenpox, herpes zoster and measles) can be very severe in patients treated with glucocorticoids. Unless they have previously had these viral diseases, patients must avoid any contact with individuals with chickenpox, herpes zoster or measles. If they are exposed to such infections while receiving prednisolone, they must contact a doctor immediately even if they have no symptoms.

Attention is drawn to athletes, as this specialty contains an active ingredient that may induce a positive reaction in tests carried out during anti-doping controls.

Related to excipients

This medicinal product contains lactose. Its use is not recommended in patients with galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption syndrome (rare hereditary disorders).

This medicine contains sorbitol. Its use is not recommended in patients with fructose intolerance (a rare hereditary disease).

This medicine contains 27 mg of sodium per tablet, which is equivalent to 1,35 % of the maximum recommended daily dietary intake of 2 g of sodium per adult by the WHO.

Hypokalaemia-inducing medicines

Hypokalaemia is a factor favouring the occurrence of heart rhythm disorders (torsades de pointes, in particular) and increasing the toxicity of certain medicines, for example digoxin. Therefore, medicines that may cause hypokalaemia are involved in a large number of interactions. These include potassium-depleting diuretics, alone or combined, stimulant laxatives, glucocorticoids, tetracosactide and amphotericin B (IV route).

Contraindicated combinations

+ Live attenuated vaccines

Except for inhaled and topical routes, and for doses above 10 mg/day of prednisone equivalent (or > 2 mg/kg/day in children or > 20 mg/day in children over 10 kg) for more than two weeks, and for corticosteroid "pulses": risk of generalised vaccinia disease, possibly fatal.

Live attenuated vaccines are contraindicated even during the 3 months following discontinuation of corticosteroid therapy.

Combinations not recommended (see section Warnings and precautions)

+ Acetylsalicylic acid

Increased bleeding risk.

Combination not recommended with anti-inflammatory doses of acetylsalicylic acid (≥ 1 g per dose and/or ≥ 3 g per day).

Associations subject to Precautions for use

+ Oral anticoagulants

Possible impact of corticosteroid therapy on the metabolism of oral anticoagulants and on that of coagulation factors. Bleeding risk specific to corticosteroid therapy (digestive mucosa, vascular fragility) at high doses or during prolonged treatment exceeding 10 days. When the combination is justified, reinforce monitoring: where appropriate, biological monitoring at 8e day, then every 15 days during corticosteroid therapy and after its discontinuation.

+ Other potassium-lowering agents

Increased risk of hypokalaemia. Monitor serum potassium and, if necessary, correct.

+ Enzyme-inducing anticonvulsants:

Decrease in plasma concentrations and efficacy of corticosteroids due to increased hepatic metabolism by the inducer; the consequences are particularly significant in Addisonian patients treated with hydrocortisone and in cases of transplantation. Clinical and biological monitoring; adjustment of the corticosteroid dosage during treatment with the inducer and after its discontinuation.

+ Digoxin

Hypokalaemia favouring toxic effects of cardiac glycosides. Correct any hypokalaemia beforehand and carry out clinical, electrolyte and electrocardiographic monitoring.

+ Isoniazid

Described for prednisolone: decrease in plasma concentrations of isoniazid. Proposed mechanism: increased hepatic metabolism of isoniazid and decreased metabolism of glucocorticoids. Clinical and biological monitoring.

+ Medicinal products liable to induce torsades de pointes

Increased risk of ventricular arrhythmias, particularly torsades de pointes. Correct any hypokalaemia before administering the product and carry out clinical, electrolyte and electrocardiographic monitoring.

+ Rifampicin

Decrease in plasma concentrations and efficacy of corticosteroids due to increased hepatic metabolism by rifampicin; the consequences are particularly significant in Addisonian patients treated with hydrocortisone and in cases of transplantation. Clinical and biological monitoring; adjustment of the corticosteroid dosage during treatment with rifampicin and after its discontinuation.

+ CYP3A inhibitors

Concomitant administration of CYP3A inhibitors (for example itraconazole, clarithromycin, erythromycin) and products containing cobicistat or ritonavir could increase the risk of systemic side effects of corticosteroids. The combination should be avoided, unless the benefits outweigh the increased risk of systemic side effects of corticosteroids. Patients should be monitored for possible systemic side effects of corticosteroids, and a reduction in the corticosteroid dose may be considered.

Associations to be taken into account

+ Fluoroquinolones

Possible increased risk of tendinopathy, or even tendon rupture (exceptional), particularly in patients receiving prolonged corticosteroid therapy.

+ Acetylsalicylic acid

Increased bleeding risk.

To be taken into account with analgesic or antipyretic doses (≥ 500 mg per dose and/or < 3 g per day).

+ Non-steroidal anti-inflammatory drugs

Increased risk of gastrointestinal ulceration and haemorrhage.

+ Ciclosporin

Increased effects of prednisolone: cushingoid appearance, reduced carbohydrate tolerance (decreased clearance of prednisolone).

+ Oestrogens

Caution is advised when a patient receiving glucocorticoids is treated concurrently with oestrogens or oestrogen-containing preparations, and clinical monitoring is recommended. A reduction in the prednisolone dose may be considered, if necessary.

Pregnancy

In animals, experimentation shows a teratogenic effect that varies according to species.

In humans, there is transplacental passage.

An increased incidence of cleft palate was observed in animal studies (see section Preclinical safety). According to data from an epidemiological study, the use of glucocorticoids during the first trimester may increase the risk of cleft lip and/or cleft palate.

PREDNISOLONE ZENTIVA should be used during pregnancy only if the benefits for the mother outweigh the risks, including those for the fetus.

During chronic diseases requiring treatment throughout pregnancy, a slight intrauterine growth retardation is possible. Neonatal adrenal insufficiency has been exceptionally observed after high-dose corticosteroid therapy.

A period of clinical (weight, diuresis) and biological monitoring of the newborn is warranted.

Breast-feeding

Prednisolone is excreted in breast milk. In case of treatment at high doses and on a chronic basis, breastfeeding is not recommended.

Fertility
