描述 | Clevidipine is a short-acting dihydropyridine calcium channel antagonist. Clevidipine is an ultrashort-acting drug for rapid reduction of blood pressure by selectively acting on the L-type Ca2+ channels on arteriolar smooth muscle. The drug's ultrashort action in reducing the blood pressure is due to its rapid hydrolysis by blood and extravascular tissue esterases, which does not depend on hepato-renal metabolism and excretion[3]. When myocytes were voltage-clamped with holding potential (VH) at -80 mV, 10 nM clevidipine decreased ICa at 0 mV by approximately 30%, but >50% when VH was -40 mV[4]. Clevidipine is an endothelium-independent arterial vasodilator that offers a potential therapeutic option in the treatment of perioperative arterial graft vasospasm and/or hypertension[2]. Clevidipine provided rapid BP control in patients with acute neurological injuries (including intracerebral haemorrhage, subarachnoid haemorrhage and acute ischaemic stroke), and was not associated with 'overshoot' in the vast majority of patients. Intravenous clevidipine was generally well tolerated and was usually associated with no reflex tachycardia or only very modest increases in heart rate[5]. Clevidipine administration during initial medical management of aortic dissection showed similar efficacy compared to SNP (sodium nitroprusside) when used as adjunct therapy to esmolol[6]. |
