Aprotinin suppresses ACE-inhibitor cough triggered by TAME-esterase.

N-alpha-Tosyl l-arginine methyl ester [TAME]-esterase appears to be an important biochemical marker, which displays potent contractile properties on bronchial tissues and aorta in vitro. TAME-esterase induced contractions have been shown to be mediated via a nitric oxide-cyclic GMP pathway. TAME-esterase has also been described to be a possible new cardiovascular risk factor among smokers.
