Romero; Solaz, M. Ballester; Marí, A. Albert; Arenas, V. Abstract: Bioequivwlence studies on bioavailability are part of the clinical development of drugs for oral use in order to identify shy drug-food interactions. For oral anti-tumor drugs, their clinical importance is currently recognized although regrettably the information available presents variability concerning the scientific evidence. Objectives: To review the available scientific evidence about oral anti-tumor medications and establish the recommendations for their administration with why geometric mean is used in bioequivalence trials.

Methods: We carried out a bibliographic search in Medline and The Cochrane Library for the period January of to March offocused on identifying those publications about drug-food interactions with oral anti-tumor medications. The bibliographical analysis was made in two steps. During the first phase, we excluded those articles in which the title or their content did not correspond with the objective settled; during the second phase, we deleted all the references duplicated in both databases.

We excluded those publications that did not make reference to the bioequivalence dictamen established by the Food and Drugs Administration FDA in their outcomes measurement. A critical appraisal of the selected articles was done according to the recommendations that the FDA established to be met by these studies. Results: At the initial search we when someone says your name 3 times references During the first phase, we excluded During the second phase, 40 studies remained 5.

From the critical appraisal of the 44 final articles, bioeequivalence were excluded 20 original articles, 4 short communications, and 1 meta-analysis because they did not include as an outcome measure the bioequivalence dictamen. The 19 2. Discussion: Currently, the clinical importance of drug-food interactions with oral anti-tumor drugs is identified more directly with the patient's safety than with the bioequivvalence of the therapy.

Given the development of these oral agents, their incorporation into the oncologic strategy displacing parenteral therapy, with monthly costs of thousands of Euros, it is necessary to perform well-designed studies on pharmacokinetics and pharmacodynamics. Their goal has to be comparing their bioavailability in the presence or absence of foods with the clinical response. In the meanwhile, to establish recommendations for their administration in relation to foods is inconsistent for some of linear equations in one variable graph questions why geometric mean is used in bioequivalence trials and their results is uncertain given the lack of studies based on the FDA bioequivalence dictamen.
