Intranasal seizure

Marco Mula
Benzodiazepines represent the first-line treatment for the acute management of epileptic seizures and status epilepticus. The emergency use of benzodiazepines must be timely, and because most seizures occur outside of the hospital environment, there is a significant need for delivery methods that are easy for nonclinical caregivers to use and administer quickly and safely. In addition, the ideal route of administration should be reliable in terms of absorption. Rectal diazepam is the only licensed formulation in the USA, whereas rectal diazepam and buccal midazolam are currently licensed in the EU...

PURPOSE: Status epilepticus (SE) requires not only urgent symptomatic treatment with antiepileptic drugs but also rapid identification and treatment of its cause. This narrative review summarizes the most important advances in classification and treatment of SE. METHOD: Data sources included MEDLINE, EMBASE,, and back tracking of references in pertinent studies, reviews, and books. RESULTS: SE is now defined as "a condition resulting either from the failure of the mechanisms responsible for seizure termination or from the initiation of mechanisms, which lead to abnormally, prolonged seizures (after time point t1)...

Clonazepam (CZ) is an anti-epileptic drug used mainly in status epilepticus (SE). The drug belongs to Class II according to BCS classification with very limited solubility and high permeability and it suffers from extensive first-pass metabolism. The aim of the present study was to develop CZ-loaded polymeric micelles (PM) for direct brain delivery allowing immediate control of SE. PM were prepared via thin film hydration (TFH) technique adopting a central composite face-centered design (CCFD). The seventeen developed formulae were evaluated in terms of entrapment efficiency (EE), particle size (PS), polydispersity index (PDI), zeta potential (ZP), and in vitro release...

The purpose of this study was to assess school nurses' perceptions of barriers to optimal management of seizures in schools. Eighty-three school nurses completed an electronic survey. Most agreed they felt confident they could identify a seizure (97.6%), give rectal diazepam (83.8%), and handle cluster seizures (67.1%), but fewer were confident they could give intranasal midazolam (63.3%), had specific information about a student's seizures (56.6%), or could swipe a vagus nerve stimulator magnet (47.4%). Nurses were more likely to be available at the time of a seizure in rural (17/20) (85%) versus suburban (21/34) (62%) or urban (8/25) (32%) schools (P = ...

Currently, evidence supports the use of intranasal midazolam as an effective, and in many cases, preferable treatment option for prolonged seizures in children. Despite this knowledge, intranasal midazolam is not routinely found as a standard of care. The goal of this project was to implement the use of intranasal midazolam as a rescue medication for prolonged seizures within a child neurology practice and, in doing so, create a model for implementation that would be replicable for other practice sites. This project focused on the development of a process to make intranasal midazolam available as a treatment option and then the creation of an educational intervention for providers within a child neurology practice...

QUESTION: There are times when parents arrive to my clinic after their child has had a seizure and a second seizure takes place in the clinic. While waiting for transport to the hospital, are there ways to stop the seizures without the need to obtain intravenous access in the clinic? ANSWER: Intravenous diazepam has been a first-line therapy to stop seizures in children for many years. Other routes of drug administration such as intramuscular, rectal, and buccal are available but have several limitations...

Epileptic seizure emergencies are life-threatening conditions, which in their most severe form, status epilepticus, have a high mortality rate if not quickly terminated. Treatment requires rapid delivery of anti-epileptics such as benzodiazepines to the brain. The nasal route is attractive due to its non-invasiveness, potential for direct nose to brain delivery, high vascularity, relatively large absorptive surface area, and avoidance of intestinal/liver metabolism. However, the limited volume of the nasal cavity and poor water solubility of anti-epileptics restrict absorption, leading to insufficient therapeutic brain levels...

BACKGROUND: Epistaxis is a common problem that occurs in up to 60% of the general population, and is a common emergency department (ED) complaint. The use of lidocaine for analgesia is common when cauterization is required for bleeds that are refractory to manual compression. Although the use of lidocaine is generally thought of as a benign intervention, it is not completely without risk. CASE REPORT: We present the case of a 19-year-old man who presented to the ED with persistent anterior epistaxis...

Water-soluble prodrugs can be rapidly converted by enzymes to hydrophobic drugs, whose aqueous thermodynamic solubilities are low, but are maintained in aqueous solution at supersaturated concentrations due to slow precipitation kinetics. Recently, we investigated avizafone (AVF) in combination with Aspergillus oryzae protease as a prodrug/enzyme system intended to produce supersaturated diazepam (DZP). Several fold enhancement of permeation of supersaturated DZP across Madin-Darby canine kidney II-wild type (MDCKII-wt) monolayers was observed, compared to saturated DZP solutions...

BACKGROUND: Neurological manifestations in dengue fever occur in <1 % of the patients and known to be due to multisystem dysfunction secondary to vascular leakage. Occurrence of wide spread cerebral haemorrhages with subdural hematoma during the leakage phase without profound thrombocytopenia and occurrence of cranial diabetes insipidus are extremely rare and had not been reported in published literature earlier, thus we report the first case. CASE PRESENTATION: A 24 year old previously healthy lady was admitted on third day of fever with thrombocytopenia...

Inhibitory synaptic receptors are dysfunctional in epileptic brains, and agents that selectively target these receptors may be effective for the treatment of epilepsy. MicroRNAs interfere with the translation of target genes, including various synaptic proteins. Here, we show that miR-203 regulates glycine receptor-β (Glrb) in epilepsy models. miR-203 is upregulated in the hippocampus of epileptic mice and human epileptic brains and is predicted to target inhibitory synaptic receptors, including Glrb. In vitro transfection, target gene luciferase assays, and analysis of human samples confirmed the direct inhibition of GLRB by miR-203, and AM203, an antagomir targeting miR-203, reversed the effect of miR-203...

Kainic acid (KA) is routinely used to elicit status epilepticus (SE) and epileptogenesis. Among the available KA administration protocols, intranasal instillation (IN) remains understudied. Dosages of KA were instilled IN in mice. Racine Scale and Video-EEG were used to assess and quantify SE onset. Time spent in SE and spike activity was quantified for each animal and confirmed by power spectrum analysis. Immunohistochemistry and qPCR were performed to define brain inflammation occurring after SE, including activated microglial phenotypes...

PURPOSE OF REVIEW: This review discusses advances in the understanding of the mechanisms of status epilepticus and its current treatment approaches. Many of these have been topics at the 5th London-Innsbruck Colloquium on status epilepticus 2015. RECENT FINDINGS: A new definition and classification of status epilepticus was proposed, which is expected to improve treatment and stimulate research. A better understanding of the failure of seizure suppressing mechanisms and the initiation of self-sustaining seizures begins to translate into the clinical arena...

UNLABELLED: Approximately half of autism spectrum disorder (ASD) individuals suffer from comorbid intellectual disabilities (IDs). Oxytocin (OXT) receptors are highly expressed in temporal lobe structures and are likely to play a modulatory role in excitatory/inhibitory balance, at least based on animal model findings. Thus, it is feasible that in the highly representative group of Kanner-type ASD subjects, OXT could have a beneficial effect on social communication and social interaction...

OBJECTIVE: Treatment of severe hypoglycemia with loss of consciousness or seizure outside of the hospital setting is presently limited to intramuscular glucagon requiring reconstitution immediately prior to injection, a process prone to error or omission. A needle-free intranasal glucagon preparation was compared with intramuscular glucagon for treatment of insulin-induced hypoglycemia. RESEARCH DESIGN AND METHODS: At eight clinical centers, a randomized crossover noninferiority trial was conducted involving 75 adults with type 1 diabetes (mean age, 33 ± 12 years; median diabetes duration, 18 years) to compare intranasal (3 mg) versus intramuscular (1 mg) glucagon for treatment of hypoglycemia induced by intravenous insulin...
