Abstract

Beta-phenylethylamine (PEA) is an endogenous amine which is metabolised by MAO B. The function of this enzyme is known to be modified by ethanol so we have studied the interactions of PEA with ethanol. Rectal temperatures of rats were determined and animals pretreated with ethanol (2.5 g kg -1 IP) 90 min before PEA 20, 40, 100 mg kg -~ IP). Spontaneous locomotor activity (SLA) was then recorded, for 30 rain, temperatures redetermined and blood ethanol levels evaluated. PEA increased SLA but did not alter rectal temperatures, and at 40 mg kg- 1 it not only attenuated ethanol hypothermia and blood levels but also modified ethanol hypomotility. The highest dose of PEA (100 mg kg- 1) decreased blood ethanol concentration and sedation but did not counteract the hypothermia. Thus PEA increased ethanol clearance, though the underlying mechanism is not totally clear. This finding is discussed in relation to its catecholaminergic and enzyme inducing characteristics.
