用途: Lidocaine, an amide local anesthetic, has anti-inflammatory properties in vitro and in vivo, possibly due to an attenuation of pro-inflammatory cytokines, intracellular adhesion molecule-1 (ICAM-1), and reduction of neutrophils influx.Target: Lidocaine is a common local anesthetic and antiarrhythmic drug. Lidocaine is used topically to relieve itching, burning and pain from skin inflammations, injected as a dental anesthetic or as a local anesthetic for minor surgery. Lidocaine, the first amino amide–type local anesthetic, was first synthesized under the name xylocaine by Swedish chemist Nils Lofgren in 1943. His colleague Bengt Lundqvist performed the first injection anesthesia experiments on himself.Lidocaine is approximately 95% metabolized (dealkylated) in the liver by CYP3A4 to the pharmacologically-active metabolites monoethylglycinexylidide (MEGX) and then subsequently to the inactive glycine xylidide. MEGX has a longer half life than lidocaine but also is a less potent sodium channel blocker. The elimination half-life of lidocaine is approximately 90–120 minutes in most patients. This may be prolonged in patients with hepatic impairment (average 343 minutes) or congestive heart failure (average 136 minutes). 作用: 利多卡因是一种局部麻醉药,又称赛罗卡因,近年来已经取代普鲁卡因,广泛应用于美容整形手术中进行局部浸润麻醉,它通过抑制神经细胞膜的钠离子通道起到阻断神经兴奋与传导作用。其脂溶性、蛋白结合率均高于普鲁卡因,穿透细胞能力强,起效快,作用时间长,作用强度是普鲁卡因的4倍。 临床应用于浸润麻醉、硬膜外麻醉、表面麻醉(包括在胸腔镜检查或腹腔手术时作黏膜麻醉用)及神经传导阻滞。为了延长麻醉的时间,减少利多卡因的中毒等副作用,可在麻醉药中加入肾上腺素。 利多卡因也可用于治疗急性心肌梗死后室性早搏、室性心动过速、于洋地黄类中毒、心脏外科手术及心导管引起的室性心律失常,包括室性早搏、室性心动过速及室颤。其次也用于癫痫持续状态用其他抗惊厥药无效者及局部或椎管内麻醉。但对室上性心律失常通常无效。 物理化学性质: CAS号:137-58-6 常用中文名:利多卡因 常用英文名:Lidocaine 分子式:C14H22N2O 分子量:234.337 密度:1.0±0.1 g/cm3 沸点:372.7±52.0 °C at 760 mmHg 熔点:66-69°C 闪点:179.2±30.7 °C
