Nitrol 20mg Injection

Mitoxantrone injection, USP (concentrate) is indicated for reducing neurologic disability and/or the frequency of clinical relapses in patients with secondary (chronic) progressive, progressive relapsing, or worsening relapsing-remitting multiple sclerosis (i.e., patients whose neurologic status is significantly abnormal between relapses). Mitoxantrone injection, USP (concentrate) is not indicated in the treatment of patients with primary progressive multiple sclerosis. The clinical patterns of multiple sclerosis in the studies were characterized as follows: secondary progressive and progressive relapsing disease were characterized by gradual increasing disability with or without superimposed clinical relapses, and worsening relapsing-remitting disease was characterized by clinical relapses resulting in a step-wise worsening of disability. Mitoxantrone injection, USP (concentrate) in combination with corticosteroids is indicated as initial chemotherapy for the treatment of patients with pain related to advanced hormone-refractory prostate cancer. Mitoxantrone injection, USP (concentrate) in combination with other approved drug(s) is indicated in the initial therapy of acute nonlymphocytic leukemia (ANLL) in adults. This category includes myelogenous, promyelocytic, monocytic, and erythroid acute leukemias.

Boxed warning. Mitoxantrone injection (concentrate) should be administered under the supervision of a physician experienced in the use of cytotoxic chemotherapy agents. Mitoxantrone injection (concentrate) should be given slowly into a freely flowing intravenous infusion. It must never be given subcutaneously, intramuscularly, or intra-arterially. Severe local tissue damage may occur if there is extravasation during administration (see ADVERSE REACTIONS, General, Cutaneous and DOSAGE AND ADMINISTRATION, Preparation and Administration Precautions ). NOT FOR INTRATHECAL USE. Severe injury with permanent sequelae can result from intrathecal administration (see WARNINGS, General ). Except for the treatment of acute nonlymphocytic leukemia, Mitoxantrone injection (concentrate) therapy generally should not be given to patients with baseline neutrophil counts of less than 1,500 cells/mm 3. In order to monitor the occurrence of bone marrow suppression, primarily neutropenia, which may be severe and result in infection, it is recommended that frequent peripheral blood cell counts be performed on all patients receiving Mitoxantrone injection (concentrate). Cardiotoxicity Congestive heart failure (CHF), potentially fatal, may occur either during therapy with Mitoxantrone injection (concentrate) or months to years after termination of therapy. Cardiotoxicity risk increases with cumulative Mitoxantrone injection (concentrate) dose and may occur whether or not cardiac risk factors are present. Presence or history of cardiovascular disease, radiotherapy to the mediastinal/pericardial area, previous therapy with other anthracyclines or anthracenediones, or use of other cardiotoxic drugs may increase this risk. In cancer patients, the risk of symptomatic CHF was estimated to be 2.6% for patients receiving up to a cumulative dose of 140 mg/m 2. To mitigate the cardiotoxicity risk with Mitoxantrone injection (concentrate), prescribers should consider the following: All Patients - All patients should be assessed for cardiac signs and symptoms by history, physical examination, and ECG prior to start of Mitoxantrone injection (concentrate) therapy. - All patients should have baseline quantitative evaluation of left ventricular ejection fraction (LVEF) using appropriate methodology (ex. Echocardiogram, multi-gated radionuclide angiography (MUGA), MRI, etc.). Multiple Sclerosis Patients - MS patients with a baseline LVEF below the lower limit of normal should not be treated with Mitoxantrone injection (concentrate). - MS patients should be assessed for cardiac signs and symptoms by history, physical examination and ECG prior to each dose.

Multiple Sclerosis Mitoxantrone injection has been administered to 149 patients with multiple sclerosis in two randomized clinical trials, including 21 patients who received Mitoxantrone injection in combination with corticosteroids. In Study 1, the proportion of patients who discontinued treatment due to an adverse event was 9.7% (n = 6) in the 12 mg/m 2 Mitoxantrone injection arm (leukopenia, depression, decreased LV function, bone pain and emesis, renal failure, and one discontinuation to prevent future complications from repeated urinary tract infections) compared to 3.1% (n = 2) in the placebo arm (hepatitis and myocardial infarction). The following clinical adverse experiences were significantly more frequent in the Mitoxantrone injection groups: nausea, alopecia, urinary tract infection, and menstrual disorders, including amenorrhea. Table 4a summarizes clinical adverse events of all intensities occurring in ≥ 5% of patients in either dose group of Mitoxantrone injection and that were numerically greater on drug than on placebo in Study 1. The majority of these events were of mild to moderate intensity, and nausea was the only adverse event that occurred with severe intensity in more than one patient (three patients [5%] in the 12 mg/m 2 group). Of note, alopecia consisted of mild hair thinning. Two of the 127 patients treated with Mitoxantrone injection in Study 1 had decreased LVEF to below 50% at some point during the 2 years of treatment. An additional patient receiving 12 mg/m 2 did not have LVEF measured, but had another echocardiographic measure of ventricular function (fractional shortening) that led to discontinuation from the study. Table 4a: Adverse Events of Any Intensity Occurring in ≥ 5% of Patients on Any Dose of Mitoxantrone Injection and That Were Numerically Greater Than in the Placebo Group Study 1 Percent of Patients Preferred Term Placebo (N = 64) 5 mg/m 2 Mitoxantrone Injection (N = 65) 12 mg/m 2 Mitoxantrone Injection (N = 62) Nausea 20 55 76 Alopecia 31 38 61 Menstrual disorder Percentage of female patients. 26 51 61 Amenorrhea 3 28 43 Upper respiratory tract infection 52 51 53 Urinary tract infection 13 29 32 Stomatitis 8 15 19 Arrhythmia 8 6 18 Diarrhea 11 25 16 Urine abnormal 6 5 11 ECG abnormal 3 5 11 Constipation 6 14 10 Back pain 5 6 8 Sinusitis 2 3 6 Headache 5 6 6 The proportion of patients experiencing any infection during Study 1 was 67% for the placebo group, 85% for the 5 mg/m 2 group, and 81% for the 12 mg/m 2 group.
