<p>K<sup>+</sup> channels blocker; cholinoreceptors antagonist; ganglioblocker.</p><br /><!–C<SUB>8</SUB>H<SUB>20</SUB>ClN–>, synthetic.</br><p>The exposure of rat tracheal segments to threshold/subthreshold concentrations of TEA produces remarkable Airway Hyperresponsiveness (AH) to cooling provocation [Chand N.].<br /><br /> K<sup>+</sup> channel blockade is involved in the induction of non specific AH in this model [4]. At the concentration of 10 mM: EC<sub>50</sub> = 3.4 �M (1.8 – 6.4). <br /><br /> 1 mM blocks InsP3-induced Ca<sup>2+</sup> release in microsomal fractions isolated from rat brain incubated in media containing 100 mM KCl. Decreases the InsP<sub>3</sub>-induced Ca<sup>2+</sup> release by 80 � 5% [5].</p></br>
