The maximum infusion rate for Cleviprex is 32 mg/hour. Most patients in clinical trials were treated with doses of 16 mg/hour or less. Because of lipid load restrictions, no more than 1000 mL (or an average of 21 mg/hour) of Cleviprex infusion is recommended per 24 hours. In clinical studies, no significant changes occurred in serum triglyceride levels in the Cleviprex treated patients. There is little experience with infusion durations beyond 72 hours at any dose. The infusion can be reduced or discontinued to achieve desired blood pressure while appropriate oral therapy is established. Safety information
Cleviprex is intended for intravenous use. Titrate drug depending on the response of the individual patient to achieve the desired blood pressure reduction. Monitor blood pressure and heart rate continually during infusion, and then until vital signs are stable. Patients who receive prolonged Cleviprex infusions and are not transitioned to other antihypertensive therapies should be monitored for the possibility of rebound hypertension for at least 8 hours after the infusion is stopped. In clinical trials, the safety profile of clevidipine was generally similar to sodium nitroprusside, nitroglycerin, or nicardipine in patients undergoing cardiac surgery.Cleviprex is contraindicated in patients with allergies to soybeans, soy products, eggs, or egg products; defective lipid metabolism such as pathologic hyperlipemia (rare genetic disorders characterized by abnormal triglyceride metabolism), lipoid nephrosis, or acute pancreatitis if it is accompanied by hyperlipidemia; and in patients with severe aortic stenosis. Hypotension and reflex tachycardia are potential consequences of rapid upward titration of Cleviprex.
Clevidipine (INN, trade name Cleviprex) is a dihydropyridine calcium channel blocker indicated for the reduction of  blood pressure when oral therapy is not feasible or not desirable. Clevidipine is used IV only and practitioners titrate this drug to lower blood pressure. It has a half-life of approximately one minute. It is rapidly inactivated by esterases. It was approved by the United States Food and Drug Administration on August 1, 2008. Basic chemical and pharmacological properties
Clevidipine is a dihydropyridine L-type calcium channel blocker, highly selective for vascular, as opposed to myocardial, smooth muscle and, therefore, has little or no effect on myocardial contractility or cardiac conduction. It 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. No increase in myocardial lactate production in coronary sinus blood has been seen, confirming the absence of myocardial ischemia due to coronary steal. Clevidipine is rapidly metabolized by esterases in the blood and extravascular tissues. Therefore, its elimination is unlikely to be affected by hepatic (liver) or renal (kidney) dysfunction. Clevidipine does not accumulate in the body, and its clearance is independent of body weight. The initial phase half-life is approximately 1 minute and the terminal half-life is approximately 15 minutes. Clevidipine will still be rapidly metabolized in pseudocholinesterase-deficient patients. Clevidipine is formulated as a lipid emulsion in 20% soybean oil (Intralipid) and contains approximately 0.2 g of fat per mL (2.0 kcal/ml).
