Simultaneous analysis of anticancer agents bortezomib, imatinib, nilotinib, dasatinib, erlotinib, lapatinib, sorafenib, sunitinib and vandetanib in human plasma using LC/MS/MS.

A new liquid chromatography-tandem mass spectrometry (LC-MS/MS) method, performed by electrospray ionization in positive mode using a triple quadrupole mass spectrometry, has been developed and validated for the simultaneous determination of bortezomib (BORT), dasatinib (DASA), imatinib (IMAT), nilotinib (NILO), erlotinib (ERLO), lapatinib (LAPA), sorafenib (SORA), sunitinib (SUNI) and vandetanib (VAND) in human plasma. Separation is achieved on an Hypersil Gold(®) PFP column using a gradient elution of 10mM ammonium formate containing 0.1% formic acid (A) and acetonitrile containing 0.

[Iatrogenic angioedema: the role of angiotensin converting enzyme inhibitor and angiotensin II receptor blockers].

Nephrologists should be aware the fact that the angioedema is a common side effect not only under angiotensin-converting enzyme (ACE) inhibitors treatment but also under sartans therapy. The frequency of angioedema under ACE inhibitors is estimated at 1 to 7 per thousand. The physiopathology of ACE angioedema implicates the lack of degradation of kinines due to the inhibition of multiple enzymes activity including ACE.
