Fludanox 50mg Injection

Fludarabine Injection is a nucleotide metabolic inhibitor indicated for: The treatment of adult patients with B-cell chronic lymphocytic leukemia (CLL) who have not responded to or whose disease has progressed during treatment with at least one standard alkylating-agent containing regimen. Benefit in treatment-naïve or non-refractory CLL patients is not established. Indication Fludarabine Injection is indicated for the treatment of adult patients with B-cell chronic lymphocytic leukemia (CLL) who have not responded to or whose disease has progressed during treatment with at least one standard alkylating-agent containing regimen. The safety and effectiveness of Fludarabine Injection in previously untreated or non-refractory patients with CLL have not been established.

Boxed warning. SEVERE BONE MARROW SUPPRESSION, CNS TOXICITY, HEMOLYTIC ANEMIA, AND PULMONARY TOXICITY Fludarabine Injection should be administered under the supervision of a qualified physician experienced in the use of antineoplastic therapy. Fludarabine injection can severely suppress bone marrow function. When used at high doses in dose-ranging studies in patients with acute leukemia, Fludarabine was associated with severe neurologic effects, including blindness, coma, and death. This severe central nervous system toxicity occurred in 36% of patients treated with doses approximately four times greater (96 mg/m 2 /day for 5 to 7 days) than the recommended dose. Similar severe central nervous system toxicity, including coma, seizures, agitation and confusion, has been reported in patients treated at doses in the range of the dose recommended for chronic lymphocytic leukemia. Instances of life-threatening and sometimes fatal autoimmune phenomena such as hemolytic anemia, autoimmune thrombocytopenia/thrombocytopenic purpura (ITP), Evans syndrome, and acquired hemophilia have been reported to occur after one or more cycles of treatment with Fludarabine Injection. Patients undergoing treatment with Fludarabine Injection should be evaluated and closely monitored for hemolysis. In a clinical investigation using Fludarabine in combination with pentostatin (deoxycoformycin) for the treatment of refractory chronic lymphocytic leukemia (CLL), there was an unacceptably high incidence of fatal pulmonary toxicity. Therefore, the use of Fludarabine Injection in combination with pentostatin is not recommended. WARNING: CNS TOXICITY, HEMOLYTIC ANEMIA, AND PULMONARY TOXICITY See full prescribing information for complete boxed warning. Severe central nervous system toxicity occurred in 36% of patients treated with doses approximately four times greater (96 mg/m 2 /day for 5 to 7 days) than the recommended dose. This toxicity was seen in ≤0.2% of patients treated at the recommended dose levels (25 mg/m 2 ). Instances of life-threatening and sometimes fatal autoimmune hemolytic anemia have been reported after one or more cycles of treatment. In a clinical investigation of the combination of Fludarabine with pentostatin (deoxycoformycin) for the treatment of refractory chronic lymphocytic leukemia (CLL), there was an unacceptably high incidence of fatal pulmonary toxicity. ( see BOXED WARNINGS ) Severe bone marrow suppression, notably anemia, thrombocytopenia and neutropenia. Monitor blood counts before and during treatment. Transfusion-associated graft-versus-host disease. Use only irradiated blood products for transfusions. Infections. Monitor for infection. Renal Insufficiency.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Very common adverse reactions include myelosuppression (neutropenia, thrombocytopenia and anemia), fever and chills, fatigue, weakness, infection, pneumonia, cough, nausea, vomiting and diarrhea. Other commonly reported events include malaise, mucositis, and anorexia. Serious opportunistic infections have occurred in CLL patients treated with Fludarabine. The most frequently reported adverse reactions and those reactions which are more clearly related to the drug are arranged below according to body system. Most common adverse reactions (incidence > 30%) include myelosuppression (neutropenia, thrombocytopenia and anemia), fever, infection, nausea and vomiting, fatigue, anorexia, cough and weakness. Hematopoietic Systems Hematologic events (neutropenia, thrombocytopenia, and/or anemia) were reported in the majority of CLL patients treated with Fludarabine. During Fludarabine treatment of 133 patients with CLL, the absolute neutrophil count decreased to less than 500/mm 3 in 59% of patients, hemoglobin decreased from pretreatment values by at least 2 grams percent in 60%, and platelet count decreased from pretreatment values by at least 50% in 55%. Myelosuppression may be severe, cumulative, and may affect multiple cell lines. Bone marrow fibrosis occurred in one CLL patient treated with Fludarabine. Several instances of trilineage bone marrow hypoplasia or aplasia resulting in pancytopenia, sometimes resulting in death, have been reported in post-marketing surveillance. The duration of clinically significant cytopenia in the reported cases has ranged from approximately 2 months to approximately 1 year. These episodes have occurred both in previously treated or untreated patients. Life-threatening and sometimes fatal autoimmune phenomena such as hemolytic anemias, autoimmune thrombocytopenia/thrombocytopenic purpura (ITP), Evans syndrome, and acquired hemophilia have been reported to occur in patients receiving Fludarabine. The majority of patients rechallenged with Fludarabine developed a recurrence in the hemolytic process. Abridged from the full prescribing information.
