PURPOSE
To examine the impact of adding droperidol to fentanyl-based intravenous patient- controlled analgesia (IVPCA) on the discontinuation of IVPCA use due to postoperative nausea and vomiting (PONV).
METHODS
Patients who underwent surgeries other than abdominal surgeries and used IVPCA between April 2014 and March 2018 were selected. Patients using IVPCA with fentanyl alone were compared to patients using droperidol added to IVPCA. Patients were allocated to one of two groups depending on the drug used for IVPCA: 1) control group, fentanyl alone; 2) droperidol group, droperidol with fentanyl. The primary endpoint was the discontinuation of IVPCA due to PONV. Secondary endpoints included PONV within 48 hours after surgery, the number of antiemetics used, pain score, and adverse effects. Propensity score matching was used to control the differences in clinical features among patients.
RESULTS
Among the 793 patients initially enrolled in this study, 145 were excluded via propensity score matching; 364 of the remaining patients received IVPCA supplemented with droperidol. Propensity score matching showed that discontinuation of IVPCA due to PONV was significantly decreased in the droperidol group compared to the control group (P = 0.01). Further, compared with the control group, the droperidol group had reduced nausea up to 24 hours after surgery (P < 0.01), and the number of vomiting episodes and use of antiemetics decreased within 12 hours after surgery (P < 0.01).
CONCLUSIONS
The addition of droperidol to IVPCA is associated with a decrease in PONV, as well as the improved continuation of pain treatment with fentanyl-based IVPCA, similar to IVPCA with morphine. However, it is necessary to monitor the side effects of this treatment.

OBJECTIVE
Duloxetine is a commonly used antidepressant that is a serotonin and norepinephrine reuptake inhibitor. We aimed to investigate the frequency and severity of clinical effects following duloxetine overdose.
METHODS
We undertook a retrospective review of duloxetine overdoses (>120 mg) admitted to two tertiary toxicology units between March 2007 and May 2021. Demographic information, details of ingestion (dose, co-ingestants), clinical effects, investigations (ECG parameters including QT interval), complications (coma [GCS < 9], serotonin toxicity, seizures and cardiovascular effects), length of stay [LOS] and intensive care unit [ICU] admission were extracted from a clinical database.
RESULTS
There were 241 duloxetine overdoses (>120 mg), median age 37 years (interquartile range [IQR]: 25-48 years) and there were 156 females (65%). The median dose was 735 mg (IQR: 405-1200 mg). In 177 patients, other medications were co-ingested, most commonly alcohol, paracetamol, quetiapine, diazepam, ibuprofen, pregabalin and oxycodone. These patients were more likely to be admitted to ICU (12 [7%] vs. none; = 0.040), develop coma (16 [9%] vs. none; = 0.008) and hypotension [systolic BP < 90 mmHg] (15 [8%] vs. one; = 0.076). Sixty four patients ingested duloxetine alone with a median dose of 840 mg (180-4200 mg). The median LOS, in the duloxetine only group, was 13 h (IQR:8.3-18 h), which was significantly shorter than those taking coingestants, 19 h (IQR:12-31 h; = 0.004). None of these patients were intubated. Six patients developed moderate serotonin toxicity, without complications and one had a single seizure. Tachycardia occurred in 31 patients (48%) and mild hypertension (systolic BP > 140 mmHg) in 29 (45%). One patient had persistent sympathomimetic toxicity, and one had hypotension after droperidol. Two patients of 63 with an ECG recorded had an abnormal QT: one QT 500 ms, HR 46 bpm, which resolved over 3.5 h and a second with tachycardia (QT 360 ms, HR 119 bpm). None of the 64 patients had an arrhythmia.
CONCLUSION
Duloxetine overdose most commonly caused sympathomimetic effects and serotonin toxicity, consistent with its pharmacology, and did not result in coma, arrhythmias or intensive care admission, when taken alone in overdose.

Expert Opinion on Drug Metabolism &... Jun 2024Dopamine (D)-receptor antagonists (RAs) were the first antiemetics used in the prophylaxis of chemotherapy-induced nausea and vomiting (CINV). (Review)
Review
INTRODUCTION
Dopamine (D)-receptor antagonists (RAs) were the first antiemetics used in the prophylaxis of chemotherapy-induced nausea and vomiting (CINV).
AREAS COVERED
Eight D-RAs, amisulpride, domperidone, droperidol, haloperidol, metoclopramide, metopimazine, olanzapine and prochlorperazine are reviewed focusing on pharmacokinetics, pharmacodynamics, antiemetic effect and side effects.
EXPERT OPINION
Since the introduction of D-RAs, antiemetics such as corticosteroids, 5-hydroxytryptamine (5-HT)-RAs and neurokinin (NK)-RAs have been developed. The classical D-RAs are recommended in the prophylaxis of CINV from low emetic risk chemotherapy, but not as a fixed component of an antiemetic regimen for moderately or highly (HEC) emetic risk chemotherapy. D-RAs are also used in patients with breakthrough nausea and vomiting. It should be emphasized, that most of these drugs are not selective for dopamine receptors.The multi-receptor targeting agent, olanzapine, is recommended in the prophylaxis of HEC-induced CINV as part of a four-drug antiemetic regimen, including a 5-HT-RA, dexamethasone and a NK-RA. Olanzapine is the most effective agent to prevent chemotherapy-induced nausea.Side effects differ among various D-RAs. Metopimazine and domperidone possess a low risk of extrapyramidal side effects. Domperidone and metoclopramide are prokinetics, whereas metopimazine delays gastric emptying and haloperidol does not influence gastric motility. Many D-RAs increase the risk of prolonged QTc interval; other side effects include sedation and orthostatic hypotension.

Comparative Study Observational Study
STUDY OBJECTIVE
Intramuscular medications are commonly used to treat agitation in the emergency department (ED). The purpose of this study is to compare intramuscular droperidol and olanzapine for treating agitation.
METHODS
This was a prospective observational study of ED patients receiving intramuscular droperidol or olanzapine for acute agitation. The treating physician determined the medication and dose; however, over time drug shortages made either olanzapine (July to September 2019) or droperidol (November 2019 to March 2020) unavailable, creating a natural experiment. The primary outcome was time to adequate sedation, assessed by the Altered Mental Status Scale (AMSS), defined as time to AMSS score less than or equal to 0.
RESULTS
We analyzed 1,257 patients (median age 42 years; 73% men); 538 received droperidol (median dose 5 mg) and 719 received olanzapine (median dose 10 mg). The majority of patients (1,086; 86%) had agitation owing to alcohol intoxication. Time to adequate sedation was 16 minutes (interquartile range 10 to 30 minutes) for droperidol and 17.5 minutes (interquartile range 10 to 30 minutes) for olanzapine (absolute difference -0.7 minutes; 95% confidence interval -2.1 to 0.5 minutes). Adjusted Cox proportional hazard model analysis revealed no difference between groups in time to sedation (hazard ratio for adequate sedation for droperidol compared with olanzapine 1.12; 95% confidence interval 1.00 to 1.25). Patients receiving olanzapine were more likely to receive additional medications for sedation (droperidol 17%; olanzapine 24%; absolute difference -8% [95% confidence interval -12% to -3%]). We observed no difference between drugs regarding adverse effects except for extrapyramidal adverse effects, which were more common with droperidol (n=6; 1%) than olanzapine (n=1; 0.1%).
CONCLUSION
We found no difference in time to adequate sedation between intramuscular droperidol and olanzapine.

Effectiveness and Safety of Intravenous Medications for the Management of Acute Disturbance (Agitation and Other Escalating Behaviors): A Systematic Review of Prospective Interventional Studies.
Acute disturbance is a broad term referring to escalating behaviors secondary to a change in mental state, such as agitation, aggression, and violence. Available management options include de-escalation techniques and rapid tranquilization, mostly via parenteral formulations of medication. While the intramuscular route has been extensively studied in a range of clinical settings, the same cannot be said for intravenous (IV); this is despite potential benefits, including rapid absorption and complete bioavailability. This systematic review analyzed existing evidence for effectiveness and safety of IV medication for management of acute disturbances. It followed a preregistered protocol (PROSPERO identification CRD42020216456) and is reported following the guidelines set by Preferred Reporting Items for Systematic Review and Meta-Analysis. APA PsycINFO, MEDLINE, and EMBASE databases were searched for eligible interventional studies up until May 30th, 2023. Data analysis was limited to narrative synthesis since primary outcome measures varied significantly. Results showed mixed but positive results for the effectiveness of IV dexmedetomidine, lorazepam, droperidol, and olanzapine. Evidence was more limited for IV haloperidol, ketamine, midazolam, chlorpromazine, and valproate. There was no eligible data on the use of IV clonazepam, clonidine, diazepam, diphenhydramine, propranolol, ziprasidone, fluphenazine, carbamazepine, or promethazine. Most studies reported favorable adverse event profiles, though they are unlikely to have been sufficiently powered to pick up rare serious events. In most cases, evidence was of low or mixed quality, accentuating the need for further standardized, large-scale, multi-arm randomized controlled trials with homogeneous outcome measures. Overall, this review suggests that IV medications may offer an effective alternative parenteral route of administration in acute disturbance, particularly in general hospital settings.

Meta-Analysis
BACKGROUND
Chemical restraint (CR) is emergency drug management for acute behavioural disturbances in people with mental illness, provided with the aim of rapid calming and de-escalating potentially dangerous situations.
AIMS
To describe a systematic review of Randomised Controlled Trials (RCTs) reporting on short-term safety and effectiveness of drugs used for CR, administered to non-consenting adults with mental health conditions, who require emergency management of acute behavioural disturbances. A meta-analysis was conducted of those RCTs with comparable interventions, outcome measures and measurement timeframes.
METHOD
Academic databases were searched for RCTs published between 1 January 1996 and 20th April 2020. Relevant RCTs were critically appraised using the 13-item JBI checklist. All RCTs were described, and step-wise filters were applied to identify studies suitable for meta-analysis. For these, forest and funnel plots were constructed, and Q and I statistics guided interpretation of pooled findings, tested using MedCalc Version 19.1.
RESULTS
Of 23 relevant RCTs, 18 (78.2% total) had excellent methodological quality scores (at least 90%). Eight RCTs were potentially relevant for meta-analysis (six of excellent quality), reporting 20 drug arms in total. Adverse events for 6-36% patients were reported in all 20 drug arms. Four drug arms from two homogenous studies of N = 697 people were meta-analysed. These RCTs tested two antipsychotic drugs (droperidol, olanzapine) delivered intravenously in either 5 mgs or 10 mg doses, with outcomes of time to calm, percentage calm within five or 10 min, and adverse events. There were no significant differences between drug arms for either measure of calm. However, 5 mg olanzapine incurred significantly lower risk of adverse events than 10 mg olanzapine (OR 0.4 (95%CI 0.2-0.8)), although no dose differences were found for droperidol.
CONCLUSION
5 mg intravenous olanzapine is recommended for quick, safe emergency management of people with acute behavioural disturbances associated with mental illness.

Randomized Controlled Trial
BACKGROUND
The optimal agent to treat acute agitation in the emergency department (ED) has not been determined. The objective of this study was to compare the effectiveness and safety of intramuscular droperidol, ziprasidone, and lorazepam for acute agitation in the ED.
METHODS
This was a randomized, double-blind trial of ED patients with acute agitation requiring parenteral sedation. The study was conducted under exception from informed consent (21 CFR 50.24) from July 2004 to March 2005. Patients were randomized to receive 5 mg of droperidol, 10 mg of ziprasidone, 20 mg of ziprasidone, or 2 mg of lorazepam intramuscularly. We recorded Altered Mental Status Scale (AMSS) scores, nasal end-tidal carbon dioxide (ETCO ), and pulse oximetry (SpO ) at 0, 15, 30, 45, 60, 90, and 120 minutes as well as QTc durations and dysrhythmias. Respiratory depression was defined as a change in ETCO consistent with respiratory depression or SpO < 90%. The primary outcome was the proportion of patients adequately sedated (AMSS ≤ 0) at 15 minutes.
RESULTS
We enrolled 115 patients. Baseline AMSS scores were similar between groups. For the primary outcome, adequate sedation at 15 minutes, droperidol administration was effective in 16 of 25 (64%) patients, compared to seven of 28 (25%) for 10 mg of ziprasidone, 11 of 31 (35%) for 20 mg of ziprasidone, and nine of 31 (29%) for lorazepam. Pairwise comparisons revealed that droperidol was more effective that the other medications, with 39% (95% confidence interval [CI] = 3% to 54%) more compared to 20 mg of ziprasidone and 33% (95% CI = 8% to 58%) more compared to lorazepam. There was no significant difference between groups in need of additional rescue sedation. Numerically, respiratory depression was lower with droperidol (3/25 [12%]) compared to 10 mg of ziprasidone (10/28 [36%]), 20 mg of ziprasidone (12/31 [39%]), or lorazepam (15/31 [48%]). One patient receiving 20 mg of ziprasidone required intubation to manage an acute subdural hematoma. No patients had ventricular dysrhythmias. QTc durations were similar in all groups.
CONCLUSIONS
Droperidol was more effective than lorazepam or either dose of ziprasidone for the treatment of acute agitation in the ED and caused fewer episodes of respiratory depression.

Review
OBJECTIVE
Agitation in children in acute care settings poses significant patient and staff safety concerns. While behavioral approaches are central to reducing agitation and oral medications are preferred, parenteral medications are used when necessary to promote safety. The goal of this systematic review was to evaluate the effectiveness and safety of an ultra-short-acting parenteral medication, droperidol, for the management of acute, severe agitation in children in acute care settings.
METHODS
A systematic review of randomized controlled trials, observational studies, and case series/reports examined the effectiveness and safety of parenteral droperidol for management of acute agitation in patients ≤21 years old in acute care settings. Effectiveness outcomes included time to sedation and need for a subsequent dose of medication. Safety outcomes were adverse effects such as QTc prolongation, hypotension, respiratory depression, and dystonic reactions.
RESULTS
A total of 431 unique articles were identified. Six articles met inclusion criteria: two in the prehospital setting, one in the emergency department, and three in the inpatient hospital setting. The articles included a prospective observational study, three retrospective observational studies, and two case reports. The largest study reported a median time to sedation of 14 min (interquartile range 10-20 min); other studies reported a time to sedation of 15 min or less. Across studies, 8%-22% of patients required a second dose of medication for ongoing agitation. The most frequent adverse effects were dystonic reactions and transient hypotension. One patient had QTc prolongation and another developed respiratory depression, but both had significant comorbidities that may have contributed. The risk of bias in included studies ranged from moderate to critical.
CONCLUSIONS
Existing data on droperidol for management of acute agitation in children suggest that droperidol is both effective and safe for acute, severe agitation in children. Data are limited by study designs that may introduce bias.

Review
Drugs for preventing post-operative nausea and vomiting in patients undergoing laparoscopic cholecystectomy: Network meta-analysis of randomized clinical trials and trial sequential analysis.
BACKGROUND
Different categories of drugs are used to reduce the incidence of post-operative nausea and vomiting (PONV) following laparoscopic cholecystectomy (LC). This study is a network meta-analysis of randomized clinical trials with such drugs.
METHODS
Electronic databases were searched for appropriate randomized clinical trials evaluating drugs reducing PONV in LC. Number of patients without PONV at 24 h was the primary outcome; and incidence of nausea and/or vomiting at 6 h and 24 h, and adverse events were the secondary outcome measures. Risk of bias was evaluated for each study. Mixed treatment comparison estimates were derived by random-effects modelling. Trial sequential analysis was carried out to assess the adequacy of evidence; and surface area under cumulative ranking curve was generated to identify the best intervention in the pool. Grading of the evidence for key comparisons was done.
RESULTS
Ninety clinical trials were included. Metoclopramide, gabapentin, dixyrazine, ondansetron, granisetron, dexamethasone, tropisetron, droperidol, droperidol/dexamethasone, droperidol/metoclopramide, granisetron/droperidol and granisetron/dexamethasone, haloperidol, dexmedetomidine, palonosetron, droperidol/ondansetron, metoclopramide/dexamethasone, haloperidol/ondansetron, haloperidol/dexamethasone, palonosetron/dexamethasone and ramosetron/dexamethasone were observed with significant benefits compared to placebo. Corticosteroid/serotonin receptor antagonists was observed with the highest probability of being the 'best' in this pool. However, the moderate quality of evidence obtained was adequate to confirm the benefits of dexamethasone and ondansetron only.
CONCLUSION
The relative effect sizes for various prophylactic anti-emetics for LC was modelled using the principles of network meta-analysis. Dexamethasone and ondansetron have the best evidence as stand-alone options and the combination is preferred in high-risk category. Caution should be exercised while interpreting the evidence as the estimates might change with head-to-head clinical trial data.
