Opmerking: 1. Zorg ervoor dat de vloeistof helder is voordat u het volgende oplosmiddel toevoegt.
2. Zorg ervoor dat u het/de oplosmiddel(en) in de juiste volgorde toevoegt. U moet ervoor zorgen dat de verkregen oplossing, bij de vorige toevoeging, een heldere oplossing is voordat u verdergaat met het toevoegen van het volgende oplosmiddel. Fysische methoden zoals vortexen, echografie of een warmwaterbad kunnen worden gebruikt om het oplossen te bevorderen.

Werkingsmechanisme (Mechanism of Action)

Targets/IC₅₀/Ki	G-CSF IL-6 IL-8 TNFα Neurokinin-1 receptor (Cell-free assay) 0.1 nM
In vitro	Aprepitant antagonizes the effects of substance P by binding to NK-1 receptors primarily in the CNS, but also in the periphery. This compound, at concentrations of 0.1 nM displaces 50% of substance P from hNK1 receptors transfected in CHO or COS cells. In radioligand binding assays, it is 3000-fold selective for the human cloned NK1 receptor versus the human cloned NK3 receptor and >50,000-fold selective over the human cloned NK2 receptor. In a range of assays at other human cloned G–protein coupled receptors, this chemical retains >50,000-fold selectivity for the human cloned NK1 receptor. It is inactive in human monoamine oxidase A and B assays and at human serotonin 5–HT1A, 5–HT2A, 5–HT2c, 5–HT3, 5–HT5, 5–HT6, and 5–HT7 receptors (IC50>3 μM). In the PANLABS panel of radioligand binding screens using native animal tissues, this compound inhibits [³H]substance P binding to native NK1 receptors in rat submaxillary gland; there are no signiﬁcant interactions of it with any other native animal G–protein coupled receptors or ion channels examined in the PANLABS screen. It is inactive in monoamine uptake site (NE, 5–HT, DA) counterscreens using human and animal tissues (IC50> 3 μM)
In vivo	Aprepitant crosses the blood–brain barrier and occupied NK-1 receptors in the brain. This compound has been shown to inhibit both acute and delayed emesis induced by cytotoxic chemotherapeutic such as cisplatin by blocking substance P. It (3 mg/kg i.v. or p.o.) inhibits the emetic response to cisplatin (10 mg/kg i.v.). The anti-emetic protection afforded by this chemical (0.1 mg/kg i.v.) is enhanced by combined treatment with either dexamethasone (20 mg/kg i.v.) or the 5–HT3 receptor antagonist ondansetron (0.1 mg/kg i.v.). In a model of acute and delayed emesis, ferrets are dosed with cisplatin (5 mg/kg i.p.) and the retching and vomiting response recorded for 72 h. Pretreatment with it (4–16 mg/kg p.o.) dose-dependently inhibits the emetic response to cisplatin. Once daily treatment with this compound (2 and 4 mg/kg p.o.) completely prevents retching and vomiting in all ferrets tested. Further when daily dosing began at 24 h after cisplatin injection, when the acute phase of emesis had already become established, it (4 mg/kg p.o. at 24 and 48 h after cisplatin) prevents retching and vomiting in three out of four ferrets. This chemical also plays a key part in transmission of pain impulses from the peripheral receptors to the CNS and is involved in various behavioural, neurochemical and cardiovascular responses to stress.
