BACKGROUND Cyclophosphamide is one of the most commonly used chemotherapy drugs worldwide. Data concerning environmental contamination and biological exposure of pharmacy personnel to this and other chemotherapy drugs are limited. OBJECTIVES To determine whether pharmacy personnel involved in preparing and checking cyclophosphamide doses were more likely to have detectable levels of this drug...

Cyclophosphamide was administered to adult male rats (130 mg/kg, single i.p. injection) and its effects on the P-450 enzymes that contribute to the activation of this drug in rat liver were then assessed. P-450-mediated cyclophosphamide 4-hydroxylase activity in isolated rat liver microsomes decreased by approximately 70% over a 9-day period following drug treatment. This decrease was due to th...

In a controlled trial, symptomatic treatment alone, or 12 weeks of cyclophosphamide or azathioprine were compared in Nigerian children with nephrotic syndrome (mainly quartan malarial nephropathy) and poorly selective proteinuria. Full remission in 2 patients in each of the two groups treated with drugs, and diminution of proteinuria in most patients in the cyclophosphamide group showed possibl...

Burkitt lymphoma was diagnosed in a patient during the third trimester of pregnancy. Treatment with a low-dose, seven-day course of intravenous cyclophosphamide gave a good response which permitted the pregnancy to be carried to term, with delivery of a normal infant. When the mother received cyclophosphamide during lactation while the baby was breast-fed, the infant's leukocyte and platelet co...

Clinical studies have demonstrated an altered pineal function in cancer patients. Owing to the documented antineoplastic activity of the pineal gland, these anomalies could have a prognostic significance. This study was carried out to monitor the effect of higher blood levels of melatonin, the most important pineal hormone, which could be applied in relation to the response to chemotherapy in h...

The immunosuppressive properties of cyclophosphamide prevent formation of anti-DNA antibodies and prolong lifespans in autoimmune NZB/NZW mice, an animal model of systemic lupus erythematosus. In the current study, NZB/NZW mice were treated with weekly doses of cyclophosphamide to determine if intermittent pulses of the drug were effective therapy. Life-long treatment with cyclophosphamide, 56 ...

AIM The purpose of this study was to perform a comparative cyclophosphamide contamination level test with Becton Dickinson® syringe plungers with Phaseal® Closed System Transfer Devices and Equashield® syringe plungers under routine oncological compounding conditions. METHOD The ChemoGlo™ sampling kit and analysis services were used to test for cyclophosphamide contamination levels on the syr...

Administration of cyclophosphamide at a dose which is lethal to 10% of control athymic nude mice resulted in sudden death within 3 h in all mice that had been pretreated with the glutathione synthesis inhibitor L-buthionine-SR-sulfoximine. In Fischer 344 rats pretreated with L-buthionine-SR-sulfoximine, the cyclophosphamide dose producing 100% acute toxicity was lowered from 500-150 mg/kg; card...

The present study deals with exploration of lipid peroxidation induction capacity of cyclophosphamide, an anticancer drug, and in vitro evaluation of ascorbic acid as a suppressor of cyclophosphamide induced lipid peroxidation. Goat liver homogenate has been used as the lipid source. This evaluation was done by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric o...
