Etoposide, a widely used anticancer drug, exhibits low and variable oral bioavailability mainly because of being substrate for the efflux transporter, P-glycoprotein (P-gp). Therefore, the present study was aimed to investigate the effect of D-α-tocopherol polyethylene glycol 1000 succinate (TPGS) and PEG 400 as P-gp inhibitors on the intestinal absorption of etoposide. Everted sacs of rat smal...

background: the activity and toxicity of etoposide in women with recurrent ovarian cancer was evaluated in a case series of women with recurrent ovarian cancer who had measurable disease, methods: all patients had plior platinum-based chemotherapy and developed progressive disease, etoposide was given as 50mg/day for 21 days every 4 weeks until progression of disease or prohibitive toxicity, be...

there is a continuing need to identify new agents that are active in ovarian cancer. etoposide is a derivative of the plant alkaloid epipodophyllotoxin. the availability of etoposide in oral preparation allows prolonged administration by the oral route. in this study, activity and toxicity of etoposide in women with recurrent ovarian cancer are described from a case series of women with recurre...

High-grade gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs, G3) are aggressive cancers of the digestive system with poor prognosis and survival. Platinum-based chemotherapy (cisplatin/carboplatin + etoposide) is considered the first-line palliative treatment. Etoposide is frequently administered intravenously; however, oral etoposide may be used as an alternative. Concerns for oral et...

BACKGROUND Etoposide is a chemotherapeutic agent, widely used for the treatment of various malignancies, including small cell lung cancer (SCLC), an aggressive disease with poor prognosis. Oral etoposide administration exhibits advantages for the quality of life of the patient as well as economic benefits. However, widespread use of oral etoposide is limited by incomplete and variable bioavaila...

Objective: To evaluate the efficacy and toxicity of the association of mitoxantrone and oral etoposide. Methods: Twelve consecutive patients with metastatic hormone-refractory prostate cancer were treated with mitoxantrone and oral etoposide. Toxicity, response rate and response duration were assessed. results: Partial response was observed in two patients (response duration of seven and four m...

There is no information on the effect of food or concurrent drug administration on the bioavailability of oral etoposide, despite the fact that treatment is frequently administered over several days and most often in combination with other cytotoxic agents. The influence of these factors has been studied in 11 patients, receiving combination cytotoxic therapy for extensive small cell lung carci...
