Bedside Snapshot
- Core Use: Rapid, titratable blood pressure control in hypertensive emergencies and perioperative/ICU settings
- Mechanism: Pure arterial vasodilator that decreases SVR and afterload with minimal effect on heart rate
- Onset/Duration: BP responds within 2–4 minutes; ultra-short context-insensitive half-life of ~1 minute; BP returns toward baseline within 5–15 minutes after stopping
- Typical Dose: 1–21 mg/hr IV infusion (0.5 mg/mL concentration); start at 1–2 mg/hr and titrate every 90 seconds to 5 minutes
- Key Danger: Hypotension, reflex tachycardia; contraindicated in soy/egg allergy and defective lipid metabolism
- Special Note: Lipid emulsion vehicle (like propofol) provides ~2 kcal/mL; consider combined lipid load with propofol or TPN
Brand & Generic Names
- Generic Name: Clevidipine butyrate
- Brand Names: Cleviprex
Medication Class
Ultra-short-acting dihydropyridine calcium channel blocker (CCB); IV arterial vasodilator
Pharmacology
Mechanism of Action:
- Dihydropyridine calcium channel blocker that selectively inhibits L-type calcium channels in arteriolar smooth muscle
- Reduces calcium influx → arterial vasodilation in systemic and coronary arteries → decreased SVR and afterload, reduced BP
- Minimal direct effect on venous capacitance vessels and cardiac conduction; does not significantly depress myocardial contractility at usual doses
- Ultra-short action is due to rapid ester hydrolysis by blood and tissue esterases, not organ-dependent clearance
Pharmacokinetics:
- Onset: BP reduction within 2–4 minutes of starting or adjusting infusion
- Peak Effect: Near steady state within ~10 minutes of a rate change
- Distribution: High protein binding; confined largely to intravascular/lipid phase during infusion
- Metabolism: Rapid ester hydrolysis by blood and tissue esterases to inactive metabolites; not dependent on liver or kidney function
- Elimination: Context-insensitive half-life ~1 minute; effect rapidly dissipates after stopping infusion (BP returns toward baseline within ~5–15 minutes)
Indications
- Short-term treatment of hypertension when oral therapy is not feasible and rapid, fine-tunable control is required
- Hypertensive emergencies, especially perioperative and neurocritical care (e.g., ICH, SAH, post-thrombectomy BP targets) where tight control is needed
- Alternative to nicardipine when very rapid titration is desired or when volume of infusion is a concern (clevidipine is more concentrated)
- Controlled hypotension during surgery in select cases per anesthesia protocols
Dosing & Administration
Available Forms:
- Ready-to-use lipid emulsion: 50 mL or 100 mL vials containing 0.5 mg/mL clevidipine (e.g., 25 mg/50 mL or 50 mg/100 mL)
- Administer undiluted using a dedicated line when possible; use a vented IV set and infusion pump
- Lipid emulsion provides ~2 kcal/mL and has the same contamination/infection precautions as propofol (tubing change intervals, etc.)
Adult Dosing (IV Infusion):
| Step | Dose (mg/hr) | Approx mL/hr (0.5 mg/mL) | Notes |
|---|---|---|---|
| Starting dose | 1–2 mg/hr | 2–4 mL/hr | Start at low end in elderly or volume-depleted patients |
| Titration increments | Double q90 sec–5 min initially | E.g., 2 → 4 → 8 mg/hr | Frequent BP checks; slow down as you approach goal |
| Typical effective range | 4–12 mg/hr | 8–24 mL/hr | Most patients controlled in this range |
| Maximum recommended dose | 21 mg/hr | 42 mL/hr | Above this, additional benefit is unlikely and risk increases |
| Elderly, frail, or very labile BP | Start 0.5–1 mg/hr | 1–2 mL/hr | Use smaller, slower titrations |
| Maximum duration (per label) | Not well studied >72 hours; in practice, often used short term until PO agents established | ||
Contraindications
Absolute Contraindications:
- Allergy to soybeans, soy products, eggs, or egg products (due to lipid emulsion components)
- Defective lipid metabolism (e.g., pathologic hyperlipidemia, lipoid nephrosis, acute pancreatitis if associated with hyperlipidemia)
- Severe aortic stenosis: vasodilation can precipitate profound hypotension and ischemia by reducing coronary perfusion pressure
- Known hypersensitivity to clevidipine or any component of the formulation
Major Precautions:
- Use caution in patients with heart failure or impaired LV function—afterload reduction can help, but excessive vasodilation may drop BP too far
- Monitor serum triglycerides if prolonged use or concurrent propofol/other lipids (risk of hypertriglyceridemia, pancreatitis)
- Because of rapid onset/offset, avoid overshooting: make small dose adjustments as you approach target BP
- Avoid use in patients who cannot tolerate even brief episodes of hypotension (e.g., critical coronary stenosis, large-vessel occlusion pre-thrombectomy)
Lipid Emulsion Warning: Clevidipine contains egg and soy components. Screen for allergies before administration. Monitor combined lipid load when used with propofol or TPN.
Adverse Effects
Common:
- Hypotension
- Reflex tachycardia or palpitations
- Headache
- Nausea
Serious:
- Severe hypotension requiring vasopressors or fluid resuscitation
- Myocardial ischemia or infarction in patients with critical coronary disease due to drop in diastolic pressure
- Atrial fibrillation or other supraventricular arrhythmias (less common)
- Hypertriglyceridemia and pancreatitis with prolonged or high-dose use (theoretic/rare, but lipid load is cumulative)
- Allergic reactions to components of the lipid emulsion
Special Populations
Elderly Patients:
- Start at lower doses (0.5–1 mg/hr) and titrate more slowly due to increased sensitivity to vasodilation
- Higher risk of hypotension and falls
Renal Impairment:
- No dose adjustment required; clevidipine is not dependent on renal elimination
Hepatic Impairment:
- No dose adjustment required; metabolism occurs via blood and tissue esterases, not hepatic enzymes
Pregnancy:
- Category C: Use only if potential benefit justifies potential risk to fetus
- Limited human data; animal studies show adverse effects
Lactation:
- Unknown if excreted in breast milk; use caution
Monitoring
Clinical Monitoring:
- Continuous noninvasive or invasive arterial blood pressure monitoring, especially during titration
- Heart rate and rhythm for reflex tachycardia or arrhythmias
- Neurologic status in neuro patients where overcorrection of BP may risk ischemia
Laboratory Monitoring:
- Serum triglycerides and lipase if prolonged therapy or if also receiving propofol or TPN lipids
- Total daily lipid load when combined with propofol or parenteral nutrition
Clinical Pearls
Clevidipine vs. Nicardipine: Clevidipine and nicardipine fill a similar niche; clevidipine is faster on/faster off, while nicardipine may be more familiar and cheaper in some systems. Ideal for situations where BP targets change rapidly (e.g., pre- vs post-clot retrieval, dynamic neuro targets).
Lipid Load Consideration: Because of its lipid vehicle, think about combined lipid load if the patient is also on propofol or TPN—especially in pancreatitis or hypertriglyceridemia.
Aortic Stenosis Warning: In aortic stenosis or fixed obstruction, any potent vasodilator (including clevidipine) can be dangerous—opt for agents that reduce HR and BP more gently (e.g., esmolol in dissection with AS).
Titration Strategy: Start low and go slow in elderly or volume-depleted patients. Make frequent small adjustments rather than large jumps to avoid overshoot. The ultra-short half-life allows for rapid corrections if BP drops too low.
Infusion Pearls: Use a vented IV set and dedicated line when possible. Change tubing per institutional protocol (similar to propofol guidelines). The 0.5 mg/mL concentration makes dose calculations straightforward: mg/hr × 2 = mL/hr.
