EDTA-free heparins, heparin fractions and fragments, processes for their preparation and pharmaceutical compositions containing them.

摘要

Heparins, heparin fractions or fragments, optionally salified with pharmaceutically acceptable cations, having molecular weight ranging from 1.000 to 30.000 D, characterized by an EDTA content lower than 0.1%, by the absence, in the <1>H-NMR spectra, of the signals due to EDTA between 2.50 and 4.00 p.p.m. and substantially free from bleeding effect and optionally free from signals, in the <1><3>C-NMR spectrum, from 80 to 86 p.p.m.
