Domperidone is rapidly absorbed after oral intake, with a peak plasma concentration between 30 and 60 minutes. However, the oral bioavailability is low (15%) due to hepatic first pass metabolism. Food intake delays the peak plasma concentration but increases the bioavailability. Domperidone binds strongly to plasma protein (91%-93%) and is widely distributed in tissues, with the exception of the central nervous system. After oral administration, domperidone is rapidly and intensively metabolized by hydroxylation and N-dealkylation by CYP3A enzymes in the gut wall and the liver.9 Two-thirds of the administrated dose are eliminated in feces and the remaining third in urine, mainly as metabolites (90%). Plasma half-life after oral intake is about 7 to 9 hours and increases in cases of renal failure.
