MESH_Definition |
An anticonvulsant that is used to treat a wide variety of seizures. It is also an anti-arrhythmic and a muscle relaxant. The mechanism of therapeutic action is not clear, although several cellular actions have been described including effects on ion channels, active transport, and general membrane stabilization. The mechanism of its muscle relaxant effect appears to involve a reduction in the sensitivity of muscle spindles to stretch. Phenytoin has been proposed for several other therapeutic uses, but its use has been limited by its many adverse effects and interactions with other drugs. |

NCIt_Definition |
The sodium salt form of phenytoin, a hydantoin derivate and non-sedative antiepileptic agent with anticonvulsant activity. Phenytoin sodium promotes sodium efflux from neurons located in the motor cortex, thereby stabilizing the neuron and inhibiting synaptic transmission. This leads to a reduction in posttetanic potentiation at synapses, an inhibition of repetitive firing of action potentials and ultimately inhibits the spread of seizure activity. |

ROCG_Guidance |
[GRADES OF RECOMMENDATION:C] Based on limited evidence, in utero exposure to carbamazepine and lamotrigine does not appear to adversely affect neurodevelopment of the offspring. There is very little evidence for levetiracetam and phenytoin. Parents should be informed that evidence on long-term outcomes is based on small numbers of children. 【推荐等级:C】应告知WWE及其伴侣,关于宫内暴露于AEDs产生的长期神经发育结果是基于少数儿童的。有限的证据表示,宫内接触CBZ和LTG似乎不会影响后代神经生长发育;使用LEV和PHT的证据很少。 https://www.rcog.org.uk/guidance/browse-all-guidance/green-top-guidelines/epilepsy-in-pregnancy-green-top-guideline-no-68/ [GRADES OF RECOMMENDATION:C] Women taking enzyme-inducing AEDs (carbamazepine, phenytoin, phenobarbital, primidone, oxcarbazepine, topiramate and eslicarbazepine) should be counselled about the risk of failure with some hormonal contraceptives. 【推荐等级:C】应告知服用酶诱导型AEDs(卡马西平、苯妥英、苯巴比妥、扑米酮、奥卡西平、托吡酯、艾司利卡西平)的WWE避孕失败的风险。 https://www.rcog.org.uk/guidance/browse-all-guidance/green-top-guidelines/epilepsy-in-pregnancy-green-top-guideline-no-68/ |
