Saxer, Till Zumbuehl, Andreas Mueller, Bert 2013-05-02 Stenosed segments of arteries significantly alter the blood flow known from healthy vessels. In particular, the wall shear stress at critically stenosed arteries is at least an order of magnitude higher than in healthy situations. This alteration represents a change in physical force and might be used as a trigger signal for drug delivery. Mechanosensitive drug delivery systems, that preferentially release their payload under increased shear stress, are discussed. Therefore, besides biological or chemical markers, physical triggers are a further principle approach for targeted drug delivery. We hypothesize that such physical trigger is much more powerful to release drugs for vasodilation, plaque stabilization or clot lysis at stenosed arteries than any known biological or chemical ones. application/pdf https://folia.unifr.ch/global/documents/303142 https://folia.unifr.ch/documents/303142/files/cvt102.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1093/cvr/cvt102 info:eu-repo/semantics/openAccess License undefined Cardiovascular Research. - 2013, vol. 99, no. 2, p. 328-333 info:eu-repo/classification/udc/61 The use of shear stress for targeted drug delivery http://purl.org/coar/resource_type/c_6501
