'Double whammy': An Unusual Co-occurrence of Idiosyncratic phenytoin-induced agranulocytosis and acute liver failure in a pediatric patient. Idiosyncratic adverse events to phenytoin therapy, such as agranulocytosis and acute liver failure, though rare, may be life-threatening. Simultaneous occurrence of both adverse events is exceedingly rare; only two cases have been reported in the literature to date. We describe such a case in a 15-year-old girl. Prompt haematological and hepatic recovery occurred after discontinuation of the drug. Given the widespread use of phenytoin in seizure disorders, clinicians prescribing this drug should be aware of its potential complications. Early recognition can considerably improve outcomes.

Clinical Pharmacogenetics Implementation Consortium (CPIC) Guideline for CYP2C9 and HLA-B Genotypes and Phenytoin Dosing: 2020 Update. Phenytoin is an antiepileptic drug with a narrow therapeutic index and large interpatient pharmacokinetic variability, partly due to genetic variation in CYP2C9. Furthermore, the variant allele HLA-B*15:02 is associated with an increased risk of Stevens-Johnson syndrome and toxic epidermal necrolysis in response to phenytoin treatment. We summarize evidence from the published literature supporting these associations and provide therapeutic recommendations for the use of phenytoin based on CYP2C9 and/or HLA-B genotypes (updates on cpicpgx.org).

Pharmacological management of prolonged seizures in Dravet syndrome including intravenous phenytoin. Dravet syndrome (DS) is an infantile onset developmental and epileptic encephalopathy. Sodium channel blockers are known to exacerbate seizures in this syndrome. Due to its high incidence, the management of prolonged seizures is crucial for DS patients. There is still ambiguity regarding the use of intravenous phenytoin for prolonged seizure in DS patients mainly due to the lack of data, raising concern about the safety of it use. We conducted a retrospective study (from January 2009 to January 2020) aiming to assess the management of prolonged seizures in DS with a focus on the use of intravenous phenytoin. Data were collected for patients admitted to our hospital for seizures lasting >5 min. Among

Levetiracetam or Phenytoin as Prophylaxis for Status Epilepticus: Secondary Analysis of the "Approaches and Decisions in Acute Pediatric Traumatic Brain Injury Trial" Dataset, 2014-2017. To compare levetiracetam and phenytoin as prophylaxis for the short-term development of status epilepticus (SE) during care of pediatric patients with acute severe traumatic brain injury (TBI). Nonprespecified secondary analysis using propensity score matching. We used the Approaches and Decisions in Acute Pediatric TBI Trial (ADAPT NCT04077411) dataset (2014-2017). Patients less than 18 years old with Glasgow Coma Scale Score less than or equal to 8 who received levetiracetam or phenytoin as a prophylactic anticonvulsant therapy. None.

Comparing the Efficacy and Safety of Levetiracetam Versus Phenytoin for Treating the Acute Phase of Neonatal Seizures. Neonatal seizure is a significant problem in this life course, and its timely and effective treatment is crucial. In this study, we compared the efficacy of levetiracetam versus phenytoin for treating the acute phase of neonatal seizures. In this single-blind case-control study , 60 consecutive children with neonatal seizures referred to the Children's medical center in Tehran, Iran, in 2018 were studied. Those neonates who had at least 30 minutes of seizure after Phenobarbital treatment were assigned to receive either phenytoin (20 mg/kg) or levetiracetam (initial dose of 40-60 mg/kg) through block randomization. The efficacy and safety of the two drugs were compared

Comparison of Efficacy and Safety of Levetiracetam Versus Phenytoin for Post-craniotomy Seizure Prophylaxis. Superiority of levetiracetam over phenytoin for postcraniotomy seizure prophylaxis in patients with a supratentorial brain tumor is controversial. We aimed to evaluate the efficacy of levetiracetam versus phenytoin for postcraniotomy seizure prophylaxis in supratentorial brain tumor . In a randomized controlled trial study, 80 patients with a supratentorial brain tumor who underwent craniotomy were allocated to levetiracetam or phenytoin group, 40 patients each. Seizure prophylaxis was started 5 days before the surgery and continued until 90 days after surgery. Phenytoin group received 100 mg oral phenytoin 3 times a day. The levetiracetam group received 500 mg oral levetiracetam 2 times

Efficacy of 48 hours dose of phenytoin in prevention of early post-traumatic seizure. Antiseizure medications, such as phenytoin sodium, have been shown in some reports to reduce the incidence of early post-traumatic seizure. These medications, however, are not without side effects which may be dose related or duration related. The risks associated with short-term therapy are minimal and often dose related (and hence avoidable). This study intends to determine the efficacy of a short-course (48-hour dose) of phenytoin in prevention of early post-traumatic seizure. This was a prospective randomised double-blind clinical intervention study. Head injured patients presenting within the first 24 hours were randomly assigned to either 48-hour dose of phenytoin or control groups, and were

Efficacy Of Levetiracetam Versus Phenytoin As A Second-Line Antiepileptic Drug In The Management Of Benzodiazepine-Refractory Status Epilepticus Among Children. Status Epilepticus (SE) is a life-threatening neurological emergency requiring appropriate therapy to terminate seizure activity. SE is managed with supportive measures and ultra-short-acting benzodiazepines. However, limited data is available in the paediatric population regarding the next best option when this fails. This study aimed at finding new data to recommend levetiracetam or phenytoin as the second-line option. One hundred and thirty-seven patients with status epilepticus were randomized into two groups; group-I was given IV Levetiracetam (LEV) at 20 mg/kg/dose over 5 minutes followed by a maintenance dose of 20mg/kg/dose

HLA-B*53:01 is a significant risk factor for liver injury due to phenytoin and other anti-epileptic drugs in African Americans. To investigate HLA alleles associated with anti-epileptics (AEDs) liver injury in African Americans (AA). 21 AA with AED DILI, 176 AA with DILI due to non-AEDs, and 5816 AA population controls were included. HLA-B*53:01 was significantly associated with aromatic AED -DILI (OR: 4.52, 95% CI: 2.42-8.44, P = 1.46x10-5). Phenytoin DILI showed the strongest association with HLA-B*53:01 (OR: 9.17; 95% CI: 3.61 - 23.28, P = 1.1x10-5). The HLA-B*53:01 allele was carried by 8 out of 9 AA phenytoin-DILI cases. HLA-B*53:01 is a significant risk factor for liver injury due to anti-epileptics, particularly phenytoin, in African Americans.

Comparison of pharmacokinetics and safety between CE-fosphenytoin sodium, fosphenytoin sodium, and phenytoin sodium after intravenous and intramuscular administration in healthy volunteers. Captisol-enabled-fosphenytoin sodium (CE-fosphenytoin sodium) injection is a modified formulation of fosphenytoin sodium. We aim to compare the intravenous and intramuscular bioavailability and safety between CE-fosphenytoin sodium, fosphenytoin sodium (Cerebyx), and phenytoin sodium (intravenous injection only). In pivotal study 1, 54 subjects were divided into three sequence groups that receive intravenous injection of 250 mg of phenytoin sodium equivalent (PE), CE-fosphenytoin sodium (T), or fosphenytoin sodium (R1) and 250 mg of phenytoin sodium (R2) in period 1. After a 14-day washout period, 36

A Phenytoin-Induced Ataxia Mimicking a Stroke. Acute ataxia is commonly the chief complaint among patients visiting the emergency department (ED). It has multiple causes including infection and immunity-related, metabolic, vascular, and organic causes. Therefore, treating physicians should consider the severity and timing of onset in relation to the initial screening tests when making of acute ataxia 14 and 4 days previously. She had visited two different hospitals, and undergone two head magnetic resonance imaging (MRI) scans which showed no evidence of a stroke, and had been diagnosed with transient ischemic attacks (TIAs) at both hospitals. She underwent a third head MRI during the ED visit, which again revealed no evidence of a stroke. The plasma levels of phenytoin, carbamazepine
