The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 3.6 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.8 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00023 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.39 SJR: 0.42 SNIP: 0.89 CiteScore™:: 5.5 H-Index: 79

ABSTRAKT

There are about 20 publications about liposomal formulations of Cyclosporin A (CyA) in the pharmaceutical and preclinical literature. Liposomal formulations were developed in order to reduce the nephrotoxicity of CyA and to increase pharmacological effects. However, conflicting results have been published as to the therapeutic properties of these formulations. This is also true for the change in pharmacokinetics and organ distribution of the liposomally encapsulated CyA as compared to conventionally formulated CyA. Using biophysical methods, it could be shown that CyA is not tightly entrapped in liposomal membranes, despite its high lipophilicity. CyA shows retardation only at high lipid concentrations in blood, following a massive injection of liposomes.This effect may diminish nephrotoxicity, as could be demonstrated by in vitro studies using a model tubule system. The results of these studies can be used to predict the formulation behavior in vivo and to optimize liposomal formulations. When applied in an early phase of the drug formulation process, these types of biophysical experiments can also help minimize animal experiments. However, these basic interaction studies cannot cover all physiological, pharmacological, and toxic effects in animals and humans.
