Etoposide is used to treat small cell lung cancer. Randomized phase III trial comparing irinotecan/cisplatin with etoposide/cisplatin in patients with previously untreated extensive-stage disease small-cell lung cancer. Several studies confirmed comparable safety and efficacy of oral and intravenous etoposide. Several CYP3A4 and ABCB1 inhibitors were described to enhance etoposide bioavailability, such as platinum compounds, cyclosporine A, hydroxyzine, quinidine, 20(S)-ginsenoside Rh2, GF120918, kaempferol, morin, quercetin, verapamil, PSC833 (valspodar), ketoconazole, piperine analogue and curcumin. The increase in bioavailability is a consequence of inhibition of metabolic enzymes and/or efflux transporters. In some cases, drug therapy may be necessary to prevent or relieve nausea and vomiting. The .gov means its official. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, sweating, chest tightness, fast or irregular heartbeat, skin turning blue, cough, trouble breathing.This is not a complete list of possible side effects. Therefore, further studies are needed to show the accuracy and precision of Bayesian method and pharmacogenetic analysis in dosage adjustment of oral etoposide in SCLC patients. PrecautionsDrug InteractionsOverdoseNotes Self-evidently, the daily dose of intravenously administered etoposide was higher than the dose of orally administered one, while the cumulative dose of etoposide per cycle was higher for orally administered etoposide. Mucositis is a common side effect of chemotherapy treatment. Clinical pharmacological profile of etoposide in elderly patients with lung cancer.

The activity of etoposide is dose- and schedule-dependent, and etoposide efficacy might be improved markedly with repeated drug administration.1217 Etoposide directly interacts with the ATP-bound enzyme monomer in such a way that each molecule of etoposide stabilizes only a single-stranded break. Because of the potential risk to the infant, breast-feeding while using etoposide is not recommended. Cancer patients commonly receive multiple medications, including chemotherapy and supportive care drugs, the majority of them are elderly, and so require medications for co-morbid conditions, and have age-related decline in hepatic and renal function that reduce their ability to metabolize and eliminate drugs.69 The possibility of drug-drug and drug-food interactions is therefore high.

Zhuo X, Zheng N, Felix CA, Blair IA. Do not use a pill that has been accidentally broken. Studies suggest that radical species, in addition to the catehol and ortho-quinone, might also be involved in the cytotoxicity of etoposide.5052 Ortho-quinone is attenuated by glutathione conjugation.53 The second way of etoposide metabolism is glucuronidation, mainly catalyzed by UGT1A1. MDR1 = multi-drug resistance protein (ABCB1, P-glycoprotein); MRP1-3 = multidrug resistance-associated proteins (ABCC1-3); BCRP = breast-cancer resistance protein (ABCG2); CYPs = cytochrome P450, Drug metabolism principally occurs in the liver, but also other tissues, like intestinal mucosa, must be considered.12 Etoposide is O-demethylated primarily by cytochrome P450 (CYP) 3A4 and to a lesser extent by CYP3A5.47,48 Furthermore, CYP1A2 and 2E1 are involved as the minor enzymatic components in this metabolic pathway.49 O-demethylated metabolite of etoposide is catehol.47 Catehol can undergo oxidation to form an ortho-quinone (and vice versa) via formation of a semi-quinone free radical. The clinical pharmacology of etoposide. Common side effects may include: sores or white patches in or around your mouth, trouble swallowing or talking, dry mouth, bad breath, altered sense of taste; nausea, vomiting; or; temporary hair loss.

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. The results of this study have warranted a phase II trial to . Altered etoposide pharmacokinetics and time to engraftment in pediatric patients undergoing autologous bone marrow transplantation. Nakamura T, Sakaeda T, Horinouchi M, Tamura T, Aoyama N, Shirakawa T, et al. Results showed that drugs that influence the rate of gastric emptying (metoclopramide, propantheline), improve the stability of etoposide in artificial intestinal fluid (ethanol, bile salts), and that drugs that decrease stomach acidity (cimetidine) had no significant effect on improving the etoposide AUC.27, Currently, the dose of etoposide is adjusted according to the body-surface area of the individual patient, but this does not yield the desired minimization in individual variation in the pharmacokinetics in adults.103. This causes cell death for both healthy and cancerous cells, and then the regrowth of healthy cells can occur. HOW TO USE: Take this medication by mouth exactly as prescribed.

Schematic representation of the efflux transporters and metabolic enzymes (marked) possibly influencing etoposide bioavailability (modified by Ref. Avoid eating grapefruit or drinking grapefruit juice while using this medication unless your doctor or. It has significant therapeutic activity in childhood leukemia, testicular tumors, Hodgkins disease, large cell lymphomas and small cell lung cancer (SCLC).1 In combined therapy with platinum compound (cisplatin or carboplatin), etoposide is used as a first-line therapy for SCLC, an aggressive disease with poor prognosis, which represents roughly 20% (1525%) of all lung cancers.27 With etoposide and cisplatin or carboplatin combination an overall response rate of approximately 75% can be anticipated. Kuo YH, Lin ZZ, Yang YY, Shao YY, Shau WY, Kuo RN, et al. Joel et al.27 investigated the use of agents that may influence etoposide stability in gastrointestinal tract and, thereby, bioavailability. Chronic scheduling maximizes the likelihood of exposing malignant cells to etoposide during sensitive periods of the cell cycle.14 However, myelosupression as the dose-limiting toxicity should be taken into account when planning the chemotherapy regimen.14 The chemotherapy treatment is therefore given in cycles, attacking cancer cells at their most sensitive periods, and allowing normal body cells time to recover.
