Comparing the effect of intermittent diazepam and continuous phenobarbital in preventing recurrent febrile seizures among children under 6 years old: A systematic review and meta-analysis.
BACKGROUND
Febrile convulsion (FC) is the most common and preventable seizure in children. This study aimed to assess the effectiveness of the diazepam and phenobarbital for preventing recurrent FC.
MATERIALS AND METHODS
In this systematic review study, literature published in English language were carefully searched in biological databases (Cochrane Library, Medline, Scopus, CINHAL, Psycoinfo, and Proquest) by February 2020.Randomized clinical trials (RCTs) and Quasi randomized trial were included in the review. Two researchers checked the literature independently. The quality of studies was assessed using the JADAD score. The potential risk for publication bias was assessed by Funnel plot and Egger's test. Meta regression test and sensitivity analysis were used to identify the reasons for heterogeneity. Given the results of assessing heterogeneity, the random effect model in RevMan5.1 software was used for meta analysis.
RESULTS
Four out of 17 studies had compared the effect of diazepam and phenobarbital in preventing recurrent FC. The result of the meta analysis showed that the use of diazepam in comparison with phenobarbital reduces the risk of recurrence FC by 34% (risk ratio = 0.66, 95% confidence interval [CI] = [0.36-1.21]), but the relationship was not statistically significant. In assessing the effect of diazepam or phenobarbital versus placebo, the results showed that the use of diazepam and phenobarbital has reduced the risk of recurrent FC by 49% (risk ratio = 0.51, 95% CI = [0.32-0.79]) and 37% (risk ratio = 0.63, 95% CI = [0.42-0.96)]), respectively, and these relationships were statistically significant ( < 0.05). Results of the meta regression test showed that the follow up time can be a reason for the heterogeneity between trials with the comparison of diazepam versus phenobarbital ( = 0.047, = 0.049) and Phenobarbital versus placebo ( = 0.022, = 0.016). According to the results of Funnel plot and Egger's test, there was evidence of publication bias ( = 0.0584 for comparison of diazepam vs. phenobarbital; = 0.0421 for comparison of diazepam vs. placebo; = 0.0402 for comparison of phenobarbital vs. placebo).
CONCLUSION
The results of this meta analysis indicated that preventive anticonvulsants can be useful in preventing recurrent convulsions in cases of febrile seizures.

Review
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.

BACKGROUND
As a retained placenta is a potential life-threatening obstetrical complication, effective and timely management is important. The estimated mortality rates from a retained placenta in developing countries range from 3% to 9%. One possible factor contributing to the high mortality rates is a delay in initiating manual removal of the placenta. Effective anaesthesia or analgesia during this procedure will provide adequate uterine relaxation and pain control, enabling it to be carried out effectively.
OBJECTIVES
To assess the effectiveness and safety of general, regional, and local anaesthesia or analgesia during manual removal of a retained placenta.
SEARCH METHODS
We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov and the World Health Organization's International Clinical Trials Registry Platform to 30 September 2019, and reference lists of retrieved studies.
SELECTION CRITERIA
We sought randomised controlled trials (RCTs), quasi-randomised controlled trials, and cluster-randomised trials that compared different methods of preoperative or intraoperative anaesthetic or analgesic, administered during the manual removal of a retained placenta.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed the study reports for inclusion, and risk of bias, extracted data and checked them for accuracy. We followed standard Cochrane methodology.
MAIN RESULTS
We identified only one randomised controlled trial (N = 30 women) that evaluated the effect of paracervical block on women undergoing manual removal of a retained placenta compared with intravenous pethidine and diazepam. The study was conducted in a hospital in Papua New Guinea. The study was at high risk of bias of performance bias and detection bias, low risk of attrition bias, and an unclear risk of selection bias, reporting bias, and other bias. The included study did not measure this review's primary outcomes of pain intensity and adverse events. The study reported that there were no women, in either group, who experienced an estimated postpartum blood loss of more than 500 mL. We are uncertain about the providers' satisfaction with the procedure, defined as their perception of achieving good pain relief during the procedure (risk ratio (RR) 1.50, 95% confidence interval (CI) 0.71 to 3.16, one study, 30 women; very low quality evidence). We are also uncertain about the women's satisfaction with the procedure, defined as their perception of achieving good pain relief during the procedure (RR 0.82, 95% CI 0.49 to 1.37; one study, 30 women; very low quality evidence). The included study did not report on any of our other outcomes of interest.
AUTHORS' CONCLUSIONS
There is insufficient evidence from one small study to evaluate the effectiveness and safety of anaesthesia or analgesia during the manual removal of a retained placenta. The quality of the available evidence was very low. We downgraded based on issues of limitations in study design (risk of bias) and imprecision (single study with small sample size, few or no events, and wide confidence intervals). There is a need for well-designed, multi-centre, randomised, controlled trials to evaluate the effectiveness and safety of different types of anaesthesia and analgesia during manual removal of a retained placenta. These studies could report on the important outcomes outlined in this review.

BACKGROUND
Postoperative delirium (POD) is a condition of cerebral dysfunction and a common complication after surgery. This study aimed to compare and determine the relative efficacy of pharmacological interventions for preventing POD using a network meta-analysis.
METHODS
We performed a systematic and comprehensive search to identify and analyze all randomized controlled trials until June 29, 2020, comparing two or more pharmacological interventions, including placebo, to prevent or reduce POD. The primary outcome was the incidence of POD. We performed a network meta-analysis and used the surface under the cumulative ranking curve (SUCRA) values and rankograms to present the hierarchy of the pharmacological interventions evaluated.
RESULTS
According to the SUCRA value, the incidence of POD decreased in the following order: the combination of propofol and acetaminophen (86.1%), combination of ketamine and dexmedetomidine (86.0%), combination of diazepam, flunitrazepam, and pethidine (84.8%), and olanzapine (75.6%) after all types of anesthesia; combination of propofol and acetaminophen (85.9%), combination of ketamine and dexmedetomidine (83.2%), gabapentin (82.2%), and combination of diazepam, flunitrazepam, and pethidine (79.7%) after general anesthesia; and ketamine (87.1%), combination of propofol and acetaminophen (86.0%), and combination of dexmedetomidine and acetaminophen (66.3%) after cardiac surgery. However, only the dexmedetomidine group showed a lower incidence of POD than the control group after all types of anesthesia and after general anesthesia.
CONCLUSIONS
Dexmedetomidine reduced POD compared with the control group. The combination of propofol and acetaminophen and the combination of ketamine and dexmedetomidine seemed to be effective in preventing POD. However, further studies are needed to determine the optimal pharmacological intervention to prevent POD.

Tetanus is a rare life-threatening condition often complicated by repetitive spasms, dysautonomia and neuromuscular respiratory failure contributing to high fatality rates in its severe form. Benzodiazepines used to treat muscle spasms pose a high risk of respiratory failure requiring mechanical ventilation, which is unaffordable and inaccessible for many. Magnesium sulfate, a cheap and widely available medication in all urban and rural health centres of LMICs for the treatment of eclampsia, can be used to control muscle spasms and dysautonomia. We thus conducted a systematic review of evidence to assess the safety and efficacy of magnesium sulfate in the treatment of tetanus. Any study published before April 15, 2021, discussing the efficacy and/or safety of MgSO4 infusion in the treatment of tetanus was systemically reviewed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Our systematic review included data from 13 studies, three were randomised, double-blind and controlled trials. The remaining ten studies were observational; six prospective and four retrospective studies. Our review showed no mortality benefit associated with the use of magnesium sulfate. However, magnesium sulfate was found to be effective in reducing spasms along with diazepam, leading to better control of dysautonomia, reduced need for mechanical ventilation and shorter hospital stay by 3-7 days. The incidence of magnesium toxicity was very low in the studies included.

INTRODUCTION
Developmental and/or epileptic encephalopathy with spike-and-wave activation in sleep (D/EE-SWAS), also referred to as electrical status epilepticus during sleep (ESES) or epileptic encephalopathy with continuous spike-and-wave during sleep (CSWS or EE-CSWS), is a spectrum of rare childhood epileptic encephalopathies that can lead to long-term cognitive impairment. Despite the importance of early diagnosis and intervention for D/EE-SWAS, there is a paucity of well-controlled clinical trial data to inform treatment, and no approved treatments are available. To assess correlations between diagnosis, treatment, and outcomes in D/EE-SWAS, we carried out a systematic review of the literature.
METHODS
In August 2020, we conducted comprehensive database searches using search terms including "electrical status epilepticus," "ESES," "CSWS," and "Landau-Kleffner syndrome." Two or more independent reviewers screened titles, abstracts, and full-text articles for those that met the following criteria: prospective studies (randomized controlled trials [RCTs] or open-label trials), retrospective studies (drug evaluations or observational studies/chart reviews), and case series with ≥ 10 participants. Both interventional and non-interventional studies were included (i.e., drug intervention was not an inclusion criterion). Articles published before 2012, review articles, animal studies, and studies of surgical or dietary interventions were excluded. Standardized data extraction templates were used to capture data on study design, patient characteristics, interventions, and outcomes from each of the selected publications. Study quality was assessed using the Cochrane Risk of Bias Tool for RCTs and the Newcastle-Ottawa Scale (NOS) or the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for retrospective, observational studies.
RESULTS
A total of 34 studies were included for full data extraction, most of which were uncontrolled and observational. Interpretation of study outcomes was limited by small study populations, variability in inclusion criteria, and inconsistency in methods of assessment and reporting of outcomes, which resulted in large heterogeneity in patients and their presenting symptoms. Despite these limitations, some patterns could be discerned. Several studies found that longer duration of ESES and younger age at onset were correlated with more severe language and cognitive deficits. In addition, several studies reported an association between improvement in cognitive outcomes and reduction in electroencephalogram (EEG) abnormalities and/or seizure frequency. In the 16 prospective or retrospective studies that evaluated drug treatments (e.g., antiseizure medications, corticosteroids, and high-dose diazepam), there was some improvement in EEG, seizure, and/or cognitive outcomes, although the specific outcomes and rates of improvement reported varied from study to study.
CONCLUSION
Long-term cognitive deficits remain common in D/EE-SWAS, and data gaps exist in the literature that preclude an evidence-based approach to managing this complex epilepsy indication. Early intervention with more effective medications is needed to optimize long-term outcomes. Sufficiently powered, randomized, double-blind, controlled trials with standardized methods and predefined primary and secondary outcomes are needed.

Review
Status epilepticus is a neurological emergency associated with high morbidity and mortality with fatal outcomes if not treated well. The goal of this study was to compare the intramuscular and intravenous treatment of individuals with status epilepticus. A search was performed on Scopus, PubMed, Embase, and Web of Science databases for articles published in the English language in peer-reviewed publications up to March 1, 2023. Studies were included if the treatment of status epileptics was compared either directly or indirectly between intramuscular and intravenous methods. In addition, relevant papers were manually screened for in the reference lists of the included studies. Non-duplicate articles were identified. Finally, five articles were included in the analysis, of which four were randomized controlled trials and one was a retrospective cohort study. The intramuscular midazolam group's time until the first seizure stopped was significantly shorter than the intravenous diazepam group's time (7.8 versus 11.2 minutes, respectively; p = 0.047). Moreover, the percentage of patients admitted was significantly lower in the intramuscular group than in the intravenous group (p = 0.01), but the lengths of stay in the intensive care unit and the hospital did not differ significantly between the groups. Regarding seizure recurrence, the intramuscular group had fewer incidences of recurrent seizures. Finally, there were no appreciable differences in safety outcomes between the two treatment arms. During the analysis, different outcomes reported after the use of intramuscular and intravenous treatments in managing patients with status epilepticus were categorized. This categorization led to a clear view of the efficacy and safety of intramuscular versus intravenous treatments in managing status epilepticus patients. The information at hand indicates that intramuscular therapy is just as successful as intravenous therapy in treating people with status epilepticus. The availability, adverse effect profile, logistics of administration, cost, and whether it is included in hospital formularies are some of the factors to be taken into consideration when choosing the drug administration technique.

Meta-Analysis
BACKGROUND
Neonatal abstinence syndrome (NAS) due to opioid withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss, seizures and neurodevelopmental problems.
OBJECTIVES
To assess the effectiveness and safety of using a sedative versus control (placebo, usual treatment or non-pharmacological treatment) for NAS due to withdrawal from opioids and determine which type of sedative is most effective and safe for NAS due to withdrawal from opioids.
SEARCH METHODS
We ran an updated search on 17 September 2020 in CENTRAL via CRS Web and MEDLINE via Ovid. We searched clinical trials databases, conference proceedings and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials.
SELECTION CRITERIA
We included trials enrolling infants with NAS born to mothers with an opioid dependence with more than 80% follow-up and using randomised, quasi-randomised and cluster-randomised allocation to sedative or control.
DATA COLLECTION AND ANALYSIS
Three review authors assessed trial eligibility and risk of bias, and independently extracted data. We used the GRADE approach to assess the certainty of the evidence.
MAIN RESULTS
We included 10 trials (581 infants) with NAS secondary to maternal opioid use in pregnancy. There were multiple comparisons of different sedatives and regimens. There were limited data available for use in sensitivity analysis of studies at low risk of bias. Phenobarbital versus supportive care: one study reported there may be little or no difference in treatment failure with phenobarbital and supportive care versus supportive care alone (risk ratio (RR) 2.73, 95% confidence interval (CI) 0.94 to 7.94; 62 participants; very low-certainty evidence). No infant had a clinical seizure. The study did not report mortality, neurodevelopmental disability and adverse events. There may be an increase in days' hospitalisation and treatment from use of phenobarbital (hospitalisation: mean difference (MD) 20.80, 95% CI 13.64 to 27.96; treatment: MD 17.90, 95% CI 11.98 to 23.82; both 62 participants; very low-certainty evidence). Phenobarbital versus diazepam: there may be a reduction in treatment failure with phenobarbital versus diazepam (RR 0.39, 95% CI 0.24 to 0.62; 139 participants; 2 studies; low-certainty evidence). The studies did not report mortality, neurodevelopmental disability and adverse events. One study reported there may be little or no difference in days' hospitalisation and treatment (hospitalisation: MD 3.89, 95% CI -1.20 to 8.98; 32 participants; treatment: MD 4.30, 95% CI -0.73 to 9.33; 31 participants; both low-certainty evidence). Phenobarbital versus chlorpromazine: there may be a reduction in treatment failure with phenobarbital versus chlorpromazine (RR 0.55, 95% CI 0.33 to 0.92; 138 participants; 2 studies; very low-certainty evidence), and no infant had a seizure. The studies did not report mortality and neurodevelopmental disability. One study reported there may be little or no difference in days' hospitalisation (MD 7.00, 95% CI -3.51 to 17.51; 87 participants; low-certainty evidence) and 0/100 infants had an adverse event. Phenobarbital and opioid versus opioid alone: one study reported no infants with treatment failure and no clinical seizures in either group (low-certainty evidence). The study did not report mortality, neurodevelopmental disability and adverse events. One study reported there may be a reduction in days' hospitalisation for infants treated with phenobarbital and opioid (MD -43.50, 95% CI -59.18 to -27.82; 20 participants; low-certainty evidence). Clonidine and opioid versus opioid alone: one study reported there may be little or no difference in treatment failure with clonidine and dilute tincture of opium (DTO) versus DTO alone (RR 0.09, 95% CI 0.01 to 1.59; 80 participants; very low-certainty evidence). All five infants with treatment failure were in the DTO group. There may be little or no difference in seizures (RR 0.14, 95% CI 0.01 to 2.68; 80 participants; very low-certainty evidence). All three infants with seizures were in the DTO group. There may be little or no difference in mortality after discharge (RR 7.00, 95% CI 0.37 to 131.28; 80 participants; very low-certainty evidence). All three deaths were in the clonidine and DTO group. The study did not report neurodevelopmental disability. There may be little or no difference in days' treatment (MD -4.00, 95% CI -8.33 to 0.33; 80 participants; very low-certainty evidence). One adverse event occurred in the clonidine and DTO group. There may be little or no difference in rebound NAS after stopping treatment, although all seven cases were in the clonidine and DTO group. Clonidine and opioid versus phenobarbital and opioid: there may be little or no difference in treatment failure (RR 2.27, 95% CI 0.98 to 5.25; 2 studies, 93 participants; very low-certainty evidence). One study reported one infant in the clonidine and morphine group had a seizure, and there were no infant mortalities. The studies did not report neurodevelopmental disability. There may be an increase in days' hospitalisation and days' treatment with clonidine and opioid versus phenobarbital and opioid(hospitalisation: MD 7.13, 95% CI 6.38 to 7.88; treatment: MD 7.57, 95% CI 3.97 to 11.17; both 2 studies, 91 participants; low-certainty evidence). There may be little or no difference in adverse events (RR 1.55, 95% CI 0.44 to 5.40; 2 studies, 93 participants; very low-certainty evidence). However, there was oversedation only in the phenobarbital and morphine group; and hypotension, rebound hypertension and rebound NAS only in the clonidine and morphine group.
AUTHORS' CONCLUSIONS
There is very low-certainty evidence that phenobarbital increases duration of hospitalisation and treatment, but reduces days to regain birthweight and duration of supportive care each day compared to supportive care alone. There is low-certainty evidence that phenobarbital reduces treatment failure compared to diazepam and very low-certainty evidence that phenobarbital reduces treatment failure compared to chlorpromazine. There is low-certainty evidence of an increase in days' hospitalisation and days' treatment with clonidine and opioid compared to phenobarbital and opioid. There are insufficient data to determine the safety and incidence of adverse events for infants treated with combinations of opioids and sedatives including phenobarbital and clonidine.

Review
BACKGROUND
Developments in ultrasound assessment of pregnancy has resulted in the increasing diagnosis of antenatal fetal issues. Many structural fetal conditions as well as complications associated with multiple pregnancies have the potential for in-utero treatment to improve both pregnancy and neonatal outcomes. Procedures such as laser ablation for twin-twin syndrome or cord occlusion for selective fetal termination require fetal immobilisation. Immobilisation of the fetus can occur through administration of medication to the mother or directly to the fetus. This improves procedural success and reduces the ongoing risk to the pregnancy. Evidence regarding the best medication and mode of delivery helps to ensure the optimal decision is made for both the mother and the fetus.
OBJECTIVES
To assess the effects of perioperative pharmacological interventions for fetal immobilisation during fetal surgery and invasive procedures on fetal, neonatal, and maternal outcomes. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (10 May 2021), and reference lists of retrieved studies.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) and quasi-RCTs (including published abstracts) which compared different classes of medication administered to the mother or fetus to allow in-utero procedures to be performed. We also included cluster-randomised trials but excluded cross-over trials.
DATA COLLECTION AND ANALYSIS
We used the standard Cochrane Pregnancy and Childbirth methods for data collection and analysis. Two review authors independently assessed trials for inclusion and risk of bias, extracted data, and checked them for accuracy.
MAIN RESULTS
One study with three trial reports met the inclusion criteria. This involved 54 women with a multiple pregnancy. The study was conducted in a tertiary European hospital maternal-fetal medicine unit and compared remifentanil to diazepam for fetal immobilisation and maternal sedation during fetoscopic surgery. Low-certainty evidence suggested that remifentanil may reduce fetal movement more than diazepam for two outcomes of fetal movement, one of fetal immobilisation at 40 minutes using a visual analogue score (VAS) (where 0 = immobile and 100 = baseline mobility), and one of gross body and limb movements (score was absolute number of movements), both assessed by a sonographer evaluating a taped ultrasound sequence (mean difference (MD) -65.00, 95% confidence interval (CI) -69.38 to -60.62 and MD -10.00, 95% CI -11.62 to -8.38; 1 study, 50 women). Surgeons may also report being more satisfied with the procedure when using remifentanil rather than diazepam (risk ratio (RR) 2.88, 95% CI 1.60 to 5.15; 1 study, 50 women; low-certainty evidence). However, maternal respiratory rate may decrease more during the surgical procedure with remifentanil compared with diazepam (MD -6.00, 95% CI -8.29 to -3.71; 1 study, 50 women; low-certainty evidence). Maternal sedation may also be worse with remifentanil compared with diazepam (RR 0.09, 95% CI 0.01 to 0.65; 1 study, 50 women; low-certainty evidence) measured using an observer assessment of alertness/sedation (where a score of < 4 equates to profound sedation and > 4 equates to insufficient sedation). Perinatal mortality and time taken to perform the procedure were not reported in the trial. We prespecified 20 outcomes and planned to use GRADE for 6 of them, all other outcomes were not able to be reported against for the purpose of meta-analysis due to data not being provided or unable to be interpreted. We assessed the included study at low risk of selection bias (appropriate random sequence generation and allocation concealment), performance bias (blinding of participants and personnel), detection bias (outcome assessors were blinded), attrition bias (incomplete outcome data minimal), and reporting bias. Our GRADE assessment for certainty of the evidence indicates that there is low certainty of the evidence.
AUTHORS' CONCLUSIONS
We were only able to include one study with a small number of women, from a single centre, a European tertiary hospital. This study was published in 2005 with an abstract of this trial published in 2004. This study evaluated two intravenous medications administered to the mother - remifentanil and diazepam. This study reported our prespecified primary outcome but only evaluated several of our secondary outcomes, which limited further assessment. Low-certainty evidence suggested that remifentanil may be better at reducing fetal movements and surgeons were more satisfied with the procedure. However, maternal sedation and depression of breathing may be worse with remifentanil. Further high-quality RCTs assessing both fetal and maternal medications are required to evaluate their efficacy for fetal immobilisation as well as safety for both mother and fetus.

Meta-Analysis
The current meta-analysis searched the literature connected to different tranquilizers used to treat elderly people and assessed it in terms of dose, types of outcomes and adverse effects, to determine a safe and acceptable tranquilizer and its optimal dose. A systematic literature review was undertaken for randomized controlled trials, case-control, retrospective and prospective studies on the use of tranquilizers in elderly patients, using PubMed, Ebsco, SCOPUS and Web of Science. PICOS criteria were used to select studies, and pertinent event data was collected. This meta-analysis includes 16 randomized control trials spanning the years 2000 to 2022, using the data from 2224 patients. The trials that were included used various tranquilizers such as diazepam, alprazolam, temazepam and lorazepam, and indicated high treatment efficacy and low adverse effects. With a -value of 0.853 for Egger's test and 0.13 for Begg's test, the current meta-analysis shows a minimal probability of publication bias. A recent meta-analysis supports the use of tranquilizers in older people to treat sleeplessness, epilepsy or anxiety, but only at modest doses, because large doses are harmful and produce numerous withdrawal symptoms.
