Cleviprex is a sterile, milky-white opaque emulsion containing 0.5 mg/mL of clevidipine, soya oil, glycerol, egg lecithin, oleic acid, disodium edetate, water for injection and sodium hydroxide to adjust pH. Cleviprex has a pH of 6.0 – 8.0 and is a ready-to-use emulsion. PHARMACOLOGY PHARMACODYNAMICS _ _ _MECHANISM OF ACTION _ Clevidipine is a dihydropyridine L-type calcium channel blocker. L-type calcium channels mediate the influx of calcium during depolarisation in arterial smooth muscle. Experiments in anaesthetised rats and dogs show that clevidipine reduces mean arterial blood pressure by decreasing systemic vascular resistance. Clevidipine does not reduce cardiac filling pressure (pre-load), confirming lack of effects on the venous capacitance vessels. _ _ _PHARMACODYNAMIC EFFECTS _ Cleviprex is titrated to achieve the desired reduction in blood pressure. In the perioperative patient population, Cleviprex produces a 4-5% reduction in systolic blood pressure (SBP) within 2-4 minutes after starting a 0.4 mcg/kg/min infusion (approximately 1-2 mg/h). In studies of up to 72 hours there was no evidence of tolerance. NH H H 3 C CH 3 O O O O O O Cl Cl CLEVIPREX 2 In most patients, full recovery of blood pressure is achieved in 5-15 minutes after the infusion is stopped. In studies of up to 72 hours there was no evidence of rebound hypertension. اقرأ الوثيقة كاملة
