Comparison of diazepam and lorazepam for the emergency treatment of adult status epilepticus: a systemic review and meta-analysis.

ABSTRACT: Status epilepticus (SE) is a life-threatening medical and neurological emergency. Prompt recognition and treatment are essential to stop the seizure and improve patient outcomes. To elucidate which benzodiazepine should be used as the first-line treatment, a systemic search of the PubMed, Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi databases was carried out to identify randomized controlled trials (RCTs) comparing i.v. administration of lorazepam and diazepam used for adult SE. The certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation approach. Only two RCTs were finally analyzed among 2182 papers extracted. The SE definitions, inclusion criteria, and doses of the drugs differed in the two studies. Of 204 patients included, 103 and 101 patients were allocated to the lorazepam and diazepam groups, respectively. The pooled risk ratio (RR) and confidence interval (CI) for lorazepam treatment on seizure cessation (two RCTs, n = 204) showed a significantly superior effect of lorazepam over diazepam (RR, 1.24; 95% CI, 1.03-1.49). No statistically significant relationship was found for mortality (two RCTs, n = 204) (RR 0.43; 95% CI, 0.43-6.90), poor neurological outcome (one RCT, n = 134) (RR, 1.10; 95% CI, 0.59-2.04), hypotension (one RCT, n = 70) (RR, 2.68; 95% CI, 0.11-63.61), and respiratory depression (two RCTs, n = 204) (RR, 1.07; 95% CI, 0.48-2.48). The certainty of the evidence was rated as very low. The results of this meta-analysis of RCTs showed that i.v. lorazepam was better than i.v. diazepam for the cessation of adult SE.

Project description:ObjectiveTo evaluate acute and long-term effects of intravenous brivaracetam (BRV) and BRV + diazepam (DZP) combination treatment in a rat model of self-sustaining status epilepticus (SSSE).MethodsRats were treated with BRV (10 mg/kg) 10 min after initiation of perforant path stimulation (PPS) as early treatment; or BRV (10-300 mg/kg), DZP (1 mg/kg), or BRV (0.3-10 mg/kg) + DZP (1 mg/kg) 10 min after the end of PPS (established SSSE). Seizure activity was recorded electrographically for 24 h posttreatment (acute effects), and for 1 week at 6-8 weeks or 12 months' posttreatment (long-term effects). All treatments were compared with control rats using one-way analysis of variance (ANOVA) and Bonferroni's test, or Kruskal--Wallis and Dunn's multiple comparison tests, when appropriate.ResultsTreatment of established SSSE with BRV (10-300 mg/kg) resulted in dose-dependent reduction in SSSE duration and cumulative seizure time, achieving statistical significance at doses ≥100 mg/kg. Lower doses of BRV (0.3-10 mg/kg) + low-dose DZP (1 mg/kg) significantly reduced SSSE duration and number of seizures. All control rats developed spontaneous recurrent seizures (SRS) 6-8 weeks after SSSE, whereas seizure freedom was noted in 2/10, 5/10, and 6/10 rats treated with BRV 200 mg/kg, 300 mg/kg, and BRV 10 mg/kg + DZP, respectively. BRV (10-300 mg/kg) showed a dose-dependent trend toward reduction of SRS frequency, cumulative seizure time, and spike frequency, achieving statistical significance at 300 mg/kg. Combination of BRV (10 mg/kg) + DZP significantly reduced SRS frequency, cumulative seizure time, and spike frequency. In the 12-month follow-up study, BRV (0.3-10 mg/kg) + low-dose DZP markedly reduced SRS frequency, cumulative seizure time, and spike frequency, achieving statistical significance at some doses. Early treatment of SSSE with BRV 10 mg/kg significantly reduced long-term SRS frequency.SignificanceThese findings support clinical evaluation of BRV for treatment of status epilepticus or acute repetitive seizures.
