[Treatment of nausea nad vomiting in palliative medicine].

Nausea and vomiting are the most distressing gastrointestinal symptoms in patients with far advanced malignant diseases. A complex pathophysiology exists between gastrointestinal tract and brainstem. Neurotransmitters play an important role. An exact history and physical examination are necessary for the choice of the antiemetic. Dependent on the cause the antiemetic, which blocks receptors peripherally or centrally, will be chosen. Main antiemetic groups are prokinetics, 5HT3-antagonists, dopaminantagonists, antihistaminics and phenothiazines. Symptom relief can be reached in 90% of the patients with a differentiated approach.
