Compounds

slow reacting substance n. Physiology (now chiefly historical) any of a group of substances that cause slow contraction of smooth muscle; spec. (more fully slow-reacting substance of anaphylaxis) such a substance (now known to be a mixture of leukotrienes) released by mast cells as part of an allergic response.Abbreviated SRS.
