Widiastuti M, Bisri DY, Rachman IA. The safety and efficacy of clevidipine for blood pressure management in neurocritical patients: a systematic review and meta-analysis. Sci Rep 2024; 14:6355. [PMID: 38491009 PMCID: PMC10942977 DOI: 10.1038/s41598-024-54667-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 02/15/2024] [Indexed: 03/18/2024] Open
Abstract
We aim to determine the safety and efficacy of clevidipine for neurocritical patients. To comprehensively identify relevant studies, a systematic search strategy was employed using the following keywords: "clevidipine", "high blood pressure", "hypertension", "Neuroscience Intensive Care", "neuro critical", and "neurosurgical patients". Searches were conducted in the Clinicaltrials.gov, PubMed, and EuroPMC databases, with the search extending until September 1, 2023. The primary outcomes of interest were the time needed to achieve the target systolic blood pressure (SBP) and the percentage of time a patient remained within the targeted SBP range. Secondary outcomes included SBP values, duration of intensive care unit (ICU) stay in days, rates of hypotension, and rates of tachycardia. We included five retrospective cohort studies (n = 443), utilizing nicardipine as the primary comparator. Comparison of the time to reach target systolic blood pressure (SBP) revealed no significant difference between medications (SMD = - 1.09, p = 0.33). Likewise, the achieved SBP target showed no notable distinction (RR = 1.15, p = 0.81). However, clevidipine exhibited a slightly higher percentage of time within the target SBP range (SMD = 0.33, p = 0.04), albeit with moderate heterogeneity. Importantly, all included studies were retrospective cohort studies, underscoring the methodological context of the investigation. Clevidipine and the control group were found to be comparable in terms of achieving target SBP. Clevidipine may have a slight advantage in maintaining blood pressure within the desired range, but further research is needed to confirm this finding.

Abstract
Acute hypertension, which may damage blood vessels, causes irreversible organ damage to the vasculature, central nervous system, kidney, and heart. Clevidipine, the first third-generation calcium channel antagonist approved by the Food and Drug Administration (FDA) in the past 20 years, is an ultra-short-acting calcium channel blocker that inhibits L-type calcium channels with high clearance and low distribution, can be rapidly metabolized into the corresponding inactive acid, and is rapidly hydrolyzed into inactive metabolites by esterase in arterial blood. Clevidipine is the same as nicardipine in that the main physiological effect is vasodilation and the main target is the arterial system, which has a limited effect on capacitor vessels. Unlike nitroglycerin, clevidipine has a limited effect on preload. In contrast to other direct-acting vasodilators, clevidipine has an ultra-short half-life due to metabolism by nonspecific blood and tissue esterases. Clevidipine trials conducted in adult populations have proven that it can rapidly control blood pressure in cardiac surgery situations and that adverse reactions to clevidipine are similar to those with other antihypertensive agents. In recent years, clinical trials have shown that clevidipine has excellent blood pressure-lowering capability in patients with acute neurological injury (hemorrhage, stroke, and subarachnoid and acute intracerebral hemorrhage), those undergoing coronary artery bypass graft or spinal surgery, and in those with cerebral aneurysm/pheochromocytoma, acute heart failure, acute aortic syndromes, or renal insufficiency with severe hypertension, and it is equivalent to commonly used blood pressure-lowering medicines such as nicardipine or nitroglycerin. However, there is a lack of large-scale clinical trial data on the efficacy and safety of clevidipine in children during the perioperative period.

Comparison of Intravenous Antihypertensives on Blood Pressure Control in Acute Neurovascular Emergencies: A Systematic Review. Neurocrit Care 2022; 37:435-446. [PMID: 34993849 DOI: 10.1007/s12028-021-01417-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Accepted: 11/30/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Acute blood pressure (BP) management in neurologic patients is paramount. Different neurologic emergencies dictate various BP goals. There remains a lack of literature determining the optimal BP regimen regarding safety and efficacy. The objective of this study was to identify which intravenous antihypertensive is the most effective and safest for acute BP management in neurologic emergencies. METHODS Ovid EBM (Evidence Based Medicine) Reviews, Ovid Embase, Ovid Medline, Scopus, and Web of Science Core Collection were searched from inception to August 2020. Randomized controlled trials or comparative observational studies that evaluated clevidipine, nicardipine, labetalol, esmolol, or nitroprusside for acute neurologic emergencies were included. Outcomes of interest included mortality, functional outcome, BP variability, time to goal BP, time within goal BP, incidence of hypotension, and need for rescue antihypertensives. The Grading of Recommendations Assessment, Development, and Evaluation approach was used to evaluate the degree of certainty in the evidence available. RESULTS A total of 3878 titles and abstracts were screened, and 183 articles were selected for full-text review. Ten studies met the inclusion criteria; however, the significant heterogeneity and very low quality of studies precluded a meta-analysis. All studies included nicardipine. Five studies compared nicardipine with labetalol, three studies compared nicardipine with clevidipine, and two studies compared nicardipine with nitroprusside. Compared with labetalol, nicardipine appears to reach goal BP faster, have less BP variability, and need less rescue antihypertensives. Compared with clevidipine, nicardipine appears to reach goal BP goal slower. Lastly, nicardipine appears to be similar for BP-related outcomes when compared with nitroprusside; however, nitroprusside may be associated with increased mortality. The confidence in the evidence available for all the outcomes was deemed very low. CONCLUSIONS Because of the very low quality of evidence, an optimal BP agent for the treatment of patients with neurologic emergencies was unable to be determined. Future randomized controlled trials are needed to compare the most promising agents.

Abstract
Perioperative hypertension is a common occurrence in the neurosurgical population, where 60% to 90% of the patients require treatment for blood pressure (BP) control. Nicardipine and clevidipine have been commonly used in neurocritical settings. This retrospective, observational study assessed the effectivity of the administration of clevidipine after nicardipine treatment failure in neurosurgical patients.We retrospectively reviewed the medical charts of adult patients who were admitted to our neurosurgical department and received clevidipine after nicardipine treatment failure for the control of BP. The primary effectivity outcome was the comparison of the percentage of time spent at targeted SBP goals during nicardipine and clevidipine administration, respectively.A total of 12 adult patients treated with clevidipine after nicardipine treatment failure and were included for data analysis. The median number of events that required dose-titration was 20.5 vs 17 during the administration of nicardipine and clevidipine, respectively (P = .534). The median percentage of time spent at targeted SBP goal was 76.2% during the administration of nicardipine and 93.4% during the administration of clevidipine (P = .123).Our study suggests that clevidipine could be an alternative effective drug with an acceptable benefit/risk ratio in the neurosurgical population that fails to achieve BP control with nicardipine treatment.

Abstract
Millions of patients worldwide are admitted for acute heart failure (AHF) each year and physicians caring for these patients are confronted with the short-term challenges of reducing symptoms while preventing end organ dysfunction without causing additional harm, and the intermediate-term challenges of improving clinical outcomes such as hospital readmission and survival. There are limited data demonstrating the efficacy of any currently available therapies for AHF to meet these goals. After diuretics, vasodilators are the most common intravenous therapy for AHF, but neither nitrates, nitroprusside, nor nesiritide have robust evidence supporting their ability to provide meaningful effects on clinical outcomes, except perhaps early symptom improvement. Recently, a number of novel agents with vasodilating properties have been developed for the treatment of AHF. These agents include serelaxin, natriuretic peptides (ularitide, cenderitide), β-arrestin-biased angiotensin II type 1 receptor ligands (TRV120027), nitroxyl donors (CXL-1020, CXL-1427), soluble guanylate cyclase modulators (cinaciguat, vericiguat), short-acting calcium channel blockers (clevidipine), and potassium channel activators (nicorandil). These development programmes range from the stage of early dose-finding studies (e.g. TRV120027, CXL-1427) to large, multicentre mortality trials (e.g. serelaxin, ularitide). There is an urgent need for agents with vasodilating properties that will improve both in-hospital and post-discharge clinical outcomes, and these novel approaches may provide opportunities to address this need.

Abstract
Management approaches for patients in the emergency department (ED) who present with acute heart failure (AHF) have largely focused on intravenous diuretics. Yet, the primary pathophysiologic derangement underlying AHF in many patients is not solely volume overload. Patients with hypertensive AHF (H-AHF) represent a clinical phenotype with distinct pathophysiologic mechanisms that result in elevated ventricular filling pressures. To optimize treatment response and minimize adverse events in this subgroup, we propose that clinical management be tailored to a conceptual model of disease that is based on these mechanisms. This consensus statement reviews the relevant pathophysiology, clinical characteristics, approach to therapy, and considerations for clinical trials in ED patients with H-AHF.

Perioperative Use of Clevidipine: A Systematic Review and Meta-Analysis. PLoS One 2016; 11:e0150625.

Abstract
Background 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. An analysis of the perioperative management of blood pressure should be considered to compare with other intravenous antihypertensive agents. Methods Analyses of the available evidence in randomized clinical trials following the PRISMA methodology as well as clinical significance according to the GRADE system were conducted. Placebo versus other antihypertensive drugs studies were included. Statistical assessments were done using the X2 and I2 tests. Results Clevidipine was more effective in maintaining the blood pressure within pre-specified ranges compared with other antihypertensive drugs (MD, -17.87 CI 95%: -29.02 to -6.72; p = 0.02). The use of Clevidipine versus placebo and rescue antihypertensive intravenous drug showed a clear reduction in rates of treatment failure (RR 0.10; IC 95%; 0.05–0.18; p <0.0001). There was no difference in the incidence of adverse events compared with placebo (RR 1.47; 95% CI 0.89 to 2.43, p = 0.14) and with other antihypertensive drugs (RR 0.78, 95% CI 0.45 to 1.35; p = 0.37). In addition, there was no difference in the incidence of atrial fibrillation (AF) between clevidipine and control groups (RR 1.09, IC del 95%: 0.65 a 1.83; p = 0.73). Conclusions Clevidipine is an ultrafast-acting drug that is highly effective for management of perioperative arterial hypertension. It is devoid of adverse effects associated with the use of other IV antihypertensives. Its favorable pharmacodynamic and pharmacokinetic properties make clevidipine the drug of choice for the management of acute perioperative hypertension. It is important to emphasize the need for further studies with a larger number of patients to confirm these findings and increase the degree of evidence.

Abstract
The ultrashort-acting dihydropyridine calcium channel antagonist clevidipine (Cleviprex(®)) has a rapid onset and offset of effect and reduces blood pressure (BP) by decreasing arteriolar resistance without affecting venous capacitance vessels. This article reviews the clinical efficacy and tolerability of intravenous clevidipine when used to manage BP in perioperative and intensive care settings, as well as summarizing its pharmacological properties. Intravenous clevidipine effectively treated preoperative and postoperative hypertension in patients undergoing cardiac surgery, according to the results of the randomized, multicentre, double-blind, phase III ESCAPE-1 and ESCAPE-2 trials. The randomized, open-label, multicentre, phase III ECLIPSE trials indicated that in terms of keeping systolic BP within the target range, clevidipine was more effective than nitroglycerin or sodium nitroprusside perioperatively and had similar efficacy to nicardipine postoperatively in cardiac surgery patients. In small, double-blind trials in patients undergoing coronary artery bypass graft surgery, perioperative clevidipine was noninferior to nitroglycerin, and postoperative clevidipine had similar efficacy to sodium nitroprusside. Noncomparative studies demonstrated that 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. In conclusion, intravenous clevidipine is a valuable agent for the management of BP in perioperative and intensive care settings.

Abstract
INTRODUCTION Clevidipine butyrate is the first intravenous antihypertensive drug to be approved by the FDA over the last decade. This medication is approved for use in the USA, Australia and New Zealand, but is still pending for approval in Europe. It is a new agent that might change the current management for severe acute hypertension in the critical care, emergency and perioperative areas. AREAS COVERED This systematic review summarizes the pharmacological and clinical characteristics of this third-generation dihydropyridine intravenous calcium channel blocker, and was done using the literature available from the first publication in 1999 up until now, including the pivotal trials that led to its approval. EXPERT OPINION This agent is arterially selective, has an ultrashort half-life, with no CYP-mediated interactions with other medications and is easily titratable. These characteristics place it in a unique category compared with other commonly used antihypertensives. Clevidipine butyrate reaches target systolic blood pressure in more than 90% of patients, within 30 min. It has a low incidence of adverse reactions and is generally well tolerated. The main goal of this review is to provide healthcare providers with a comprehensive appraisal of this promising medication.

Abstract
Injectable lipid emulsions, for decades, have been clinically used as an energy source for hospitalized patients by providing essential fatty acids and vitamins. Recent interest in utilizing lipid emulsions for delivering lipid soluble therapeutic agents, intravenously, has been continuously growing due to the biocompatible nature of the lipid-based delivery systems. Advancements in the area of novel lipids (olive oil and fish oil) have opened a new area for future clinical application of lipid-based injectable delivery systems that may provide a better safety profile over traditionally used long- and medium-chain triglycerides to critically ill patients. Formulation components and process parameters play critical role in the success of lipid injectable emulsions as drug delivery vehicles and hence need to be well integrated in the formulation development strategies. Physico-chemical properties of active therapeutic agents significantly impact pharmacokinetics and tissue disposition following intravenous administration of drug-containing lipid emulsion and hence need special attention while selecting such delivery vehicles. In summary, this review provides a broad overview of recent advancements in the field of novel lipids, opportunities for intravenous drug delivery, and challenges associated with injectable lipid emulsions.
