Clevidipine
Indications
Hypertension
Adult Dose
Hypertension
Infusion solution
1-2 mg/hr (2-4 mL/hr), double dose q90sec initially; as blood pressure approaches goal, increase dose by less than doubling, and increase time between adjustments to q5-10min
Maintenance: 4-6 mg/hr; not to exceed 21 mg/hr (1000 mL within 24 hour period)
Renal Dose
Renal Impairment
Dose adjustment not necessary
Elderly Dose
Hypertension
1-2 mg/hr (2-4 mL/hr), double dose q90sec initially; as blood pressure approaches goal, increase dose by less than doubling, and increase time between adjustments to q5-10min
Maintenance: 4-6 mg/hr; not to exceed 21 mg/hr (1000 mL within 24 hour period)
Hepatic Dose
Hepatic Impairment
Dose adjustment not necessary
Administration
IV Administration
Milky white emulsion
No preservatives-use within 4 hr of puncturing stopper
Doesn't need dilution
Contra Indications
Hypersensitivity to drug, soy or egg products
Defective lipid metabolism
Acte pancreatitis if accompanied by hyperlipidemia
Severe aortic stenosis
Precautions
Maintain aseptic technique. Discard the unused portion 12 hours after stopper puncture.
Hypotension and reflex tachycardia are potential consequences of rapid upward titration of Cleviprex.
Dihydropyridine calcium channel blockers can produce negative inotropic effects and exacerbate heart failure.
Cleviprex gives no protection against the effects of abrupt beta-blocker withdrawal.
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.
Monitoring Parameters:
Monitor blood pressure and heart rate during infusion and until vital signs stabilize.
Monitor heart failure patients carefully.
Pregnancy-Lactation
Not Classi
Pregnancy
Available data based on post-marketing reports with use in pregnant women are not sufficient to inform a drug-associated risk for major birth defects, miscarriage, or adverse maternal or fetal outcomes; there are risks to mother and fetus associated with poorly controlled hypertension in pregnancy
Hypertension in pregnancy increases maternal risk for pre-eclampsia, gestational diabetes, premature delivery, and delivery complications (eg, need for cesarean section and postpartum hemorrhage); hypertension increases fetal risk for intrauterine growth restriction and intrauterine death; pregnant women with hypertension should be carefully monitored and managed accordingly
Animal data
In animal studies, drug was associated with increased incidences of intrauterine deaths, slightly reduced fetal weight, retarded skeletal development, abortion, and embryo lethality at doses higher than the expected human dose
No evidence of embryo-fetal malformation was found with continuous IV infusion of clevidipine administered to pregnant rats and rabbits during the period of organogenesis at multiples of 2.8 and 7.6 times the expected human dose of 16 mg/hr respectively
Lactation
There are no data on presence of drug in human milk, effects on breastfed infant, or on milk production

Mechanism of Action
Calcium channel blocker (dihydropyridine): inhibits transmembrane influx of extracellular Ca ions across membranes of myocardial cells and vascular smooth muscle cells, without changing serum calcium concentrations, resulting in inhibition of cardiac and vascular smooth muscle contraction, thereby dilating main coronary and systemic arteries
