Slow reacting substance of anaphylaxis
The Slow reacting substance of anaphylaxis or SRS-A is a mixture of the leukotrienes LTC4, LTD4 and LTE4. Mast cells secrete it during the anaphylactic reaction, inducing inflammation. [1]
It induced prolonged, slow contraction of smooth muscle and has a major bronchoconstrictor role in asthma.[2]
