Stearoylethanolamide (SEA) is an endocannabinoid neurotransmitter.
Stearoylethanolamide (C<sub>20</sub>H<sub>41</sub>NO<sub>2</sub>; 18:0), also called N-(octadecanoyl)ethanolamine, is an N-acylethanolamine and the ethanolamide of octadecanoic acid (C<sub>18</sub>H<sub>36</sub>O<sub>2</sub>; 18:0) and ethanolamine (MEA: C<sub>2</sub>H<sub>7</sub>NO), and functionally related to an octadecanoic acid.
Levels of SEA correlate with changes in pain intensity, indicating this SEA change, reflect the pain reduction effects of IPRP.
