Fetal hydantoin syndrome, also called fetal dilantin syndrome, is a group of defects caused to the developing fetus by exposure to teratogenic effects of phenytoin. Dilantin is the brand name of the drug phenytoin sodium in the United States, commonly used in the treatment of epilepsy.
The mechanism of action of phenytoin sodium. Sodium channels are: 1) Closed 2) Open 3) Inactive (phenytoin effect) Phenytoin is believed to protect against seizures by causing voltage-dependent block of voltage gated sodium channels. [46] This blocks sustained high frequency repetitive firing of action potentials. This is accomplished by ...
During pregnancy, the metabolism of many anticonvulsants is affected. There may be an increase in the clearance and resultant decrease in the blood concentration of lamotrigine, phenytoin, and to a lesser extent carbamazepine, and possibly decreases the level of levetiracetam and the active oxcarbazepine metabolite, the monohydroxy derivative.

The hydantoin group can be found in several medicinally important compounds. [1] In pharmaceuticals, hydantoin derivatives form a class of anticonvulsants; [8] phenytoin and fosphenytoin both contain hydantoin moieties and are both used as anticonvulsants in the treatment of seizure disorders.
Pregnant patients with epilepsy should keep track of their seizure activity and report all breakthrough seizures, regardless of severity, to their healthcare providers. Sleep deprivation , which often happens in the third trimester of pregnancy and the postpartum period, is a common seizure trigger (particularly for frontal lobe and idiopathic ...
Progesterone causes many changes to the genitourinary system. A pregnant woman may experience an increase in the size of the kidneys and ureter due to the increase blood volume and vasculature. Later in pregnancy, the woman might develop physiological hydronephrosis and hydroureter, which are normal. [33]
Filmed in Hertfordshire, England, on Nov. 5, the clip shows the touching and intimate moment between the close-knit family, including the daughter's unexpected reaction.
Fosphenytoin, also known as fosphenytoin sodium, and sold under the brand name Cerebyx among others, is a water-soluble phenytoin prodrug that is administered intravenously to deliver phenytoin, potentially more safely than intravenous phenytoin. It is used in the acute treatment of convulsive status epilepticus. Fosphenytoin was developed in 1996.
