Src, undtagen for PDGF -, Kit - and Ephrin- receptorkinaser, som det hæmmer ved koncentrationer inden for det interval, der opnås efter oral administration ved terapeutiske doser, der anbefales til behandling af CML (se tabel 4).
Tasigna has little or no effect against the majority of other protein kinases examined, including Src, except for the PDGF, Kit and Ephrin receptor kinases, which it inhibits at concentrations within the range achieved following oral administration at therapeutic doses recommended for the treatment of CML (see Table 4).
