Pharmacodynamics (Effect)This section has been translated automatically.
Sunitinib (like sorafenib) is a targeted tumor therapy and blocks the tyrosine kinase of the receptors PDGFR (platelet-derived-growth-fctor). Furthermore, sunitinib inhibits the tyrosine kinase of VEGFR (vascular endothelial growth factor - see below VEGF) and c-Kit. It also inhibits some serine threonine kinases (multi-kinase inhibitors). Sunitinib thus switches off the signalling effect of growth factors at the molecular level, which the tumour needs for its growth.

The major serious side effects of sunitinib are pulmonary embolism (1% of cases), thrombocytopenia (1%), neutropenia with fever (0.4%), and hypertension (0.4%). The most commonly reported adverse events were fatigue/exhaustion (the so-called fatigue syndrome), which affects about one-third of patients. Frequently (>20% of cases), diarrhoea, nausea, stomatitis continue to occur.
Typical side effects on the skin organ are observed from the 3rd-4th week of treatment:
- Hand-foot syndrome
- Xerosis of the skin
- diffuse effluvium with alopecia
- subungual haemorrhages (splinter hemorrhages)
- Depigmentation of skin and hair
- periocular edema.
