应用 使用吡那地尔： 通过注入左前降支用于复极化研究 在心室肌细胞中诱导ATP敏感性K+ (KATP)电流，用于电生理检查 作为KATP开启剂来治疗心肌细胞 Pinacidil is a K+ channel opener. Pinacidil is demonstrated to induce relaxation of serotonin-produced contractions in porcine and human arterial rings. This action is suppressed by the ATP-dependent K+ (KATP) channel blockers Glibenclamide and Tetrapentylammonium salts, suggesting that relaxations induced by Pinacidil are mediated by opening of KATP channels. A K+ channel activator; antihypertensive Application Use pinacidil: Repolarization study by injection of left anterior descending branch Induction of ATP sensitive K + (KATP) currents in ventricular myocytes for electrophysiological examination As a KATP opener to treat cardiomyocytes
