CYCLOPHOSPHAMIDE Coated Tablet Ref.[6752] Active ingredients: Cyclophosphamide

Cyclophosphamide Tablets are for oral use.

Cyclophosphamide should only be used by clinicians experienced in the use of cancer chemotherapy. Cyclophosphamide should only be administered where there are facilities for regular monitoring of clinical, biochemical and haematological parameters before, during, and after administration and under the direction of a specialist oncology service.

Posology

Dosage must be individualized. Doses and duration of treatment and/or treatment intervals depend on the therapeutic indication, the scheme of a combination therapy, the patient’s general state of health and organ function, and the results of laboratory monitoring (in particular, blood cell monitoring).

The dosage regimen used for most indications is 100–300 mg daily as a single or divided dose.

This treatment should be continued until a clear remission or improvement is seen or be interrupted when the extent of leucopenia becomes unacceptable.

In combination with other cytostatics of similar toxicity, a dose reduction or extension of the therapy-free intervals may be necessary.

Activation of cyclophosphamide requires hepatic metabolism; therefore, oral and intravenous administrations are preferred.

Use of hematopoiesis stimulating agents (colony-stimulating factors and erythropoiesis stimulating agents) may be considered to reduce the risk of myelosuppressive complications and/or help facilitate the delivery of the intended dosing.

During or immediately after the administration, adequate amounts of fluid should be ingested or infused to force diuresis in order to reduce the risk of urinary tract toxicity. Therefore, cyclophosphamide should be administered in the morning. See Section 4.4.

Patients with Hepatic Impairment

Severe hepatic impairment may be associated with decreased activation of cyclophosphamide. This may alter the effectiveness of cyclophosphamide treatment and should be considered when selecting the dose and interpreting response to the dose selected.

Patients with Renal Impairment

In patients with renal impairment, particularly in patients with severe renal impairment, decreased renal excretion may result in increased plasma levels of cyclophosphamide and its metabolites. This may result in increased toxicity and should be considered when determining the dosage in such patients.

Cyclophosphamide and its metabolites are dialyzable, although there may be differences in clearance depending upon the dialysis system being used. In patients requiring dialysis, use of a consistent interval between cyclophosphamide administration and dialysis should be considered. See Section 4.4.

Elderly

In elderly patients, monitoring for toxicities and the need for dose adjustment should reflect the higher frequency of decreased hepatic, renal, cardiac, or other organ function, and concomitant diseases or other drug therapy in this population.

Children

No specific information. Children have received Cyclophosphamide. No adverse reactions specific to this group have been reported.

Method of Administration

Cyclophosphamide Tablets should be swallowed with sufficient fluid without chewing. The tablets are coated and should not be divided before use.

Serious consequences of overdosage include manifestations of dose dependent toxicities such as myelosuppression, urotoxicity, cardiotoxicity (including cardiac failure), veno-occlusive hepatic disease, and stomatitis. See Section 4.4.

Patients who received an overdose should be closely monitored for the development of toxicities, and haematotoxicity in particular.

No specific antidote for cyclophosphamide is known.

Cyclophophamide and its metabolites are dialysable. Consider haemodialysis in cases of severe overdose presenting early, particularly in patients with renal impairment

Overdosage should be managed with supportive measures, including appropriate, state-of-the-art treatment for any concurrent infection, myelosuppression, or other toxicity, should it occur.

Cystitis prophylaxis with mesna may be helpful in preventing or limiting urotoxic effects with cyclophosphamide overdose.

36 months.

Do not store above 25°C.

Store in original container.

10 tablets in a PVC/aluminium blister strip and 10 blister strips in a box.

Cyclophosphamide is a cytotoxic agent. The handling of cyclophosphamide should always be in accordance with current guidelines on safe handling of cytotoxic agents.

The coating of the tablets prevents direct contact of persons handling the tablets with the active substance. To prevent inadvertent exposure of third persons to the active substance, the tablets should not be divided or crushed.

The tablets should not be handled by women who are pregnant or who are breast feeding.
