Acutely elevated blood pressure in the critical care setting is associated with a higher risk of acute end-organ damage (eg, myocardial ischemia, stroke, and renal failure) and perioperative bleeding. Urgent treatment and careful blood pressure control are crucial to prevent significant morbidity. Clevidipine butyrate (Cleviprex) is an ultrashort-acting, third-generation intravenous calcium channel blocker. It is an arterial-selective vasodilator with no venodilatory or myocardial depressive effects. Clevidipine has an extremely short half-life of approximately 1 minute as it is rapidly metabolized by blood and tissue esterases. These metabolites are then primarily eliminated through urine and fecal pathways. The rapid onset and the short duration of action permit tighter and closer adjustment of the blood pressure than is possible with other intravenous agents.
在重症监护环境中,急性血压升高与急性终末器官损伤(如心肌缺血、中风和肾衰竭)及围手术期出血的风险较高相关。紧急治疗和谨慎控制血压对于预防严重发病至关重要。丁酸氯维地平(Cleviprex)是一种超短效的第三代静脉用钙通道阻滞剂。它是一种动脉选择性血管扩张剂,无静脉扩张或心肌抑制作用。由于丁酸氯维地平可被血液和组织酯酶快速代谢,其半衰期极短,约为1分钟。这些代谢产物随后主要通过尿液和粪便途径排出。与其他静脉用药相比,其起效迅速且作用持续时间短,使得血压能够更严格、更紧密地得到调整。
