Sunday, September 30, 2018 7:03:11 PM EDT Question 30 Response Feedback: A patient has a history of tonic-clonic seizures that have been successfully treated with phenytoin (Dilantin) for several years. Phenytoin achieves a therapeutic e ff ect by Phenytoin reversibly binds to sodium channels while they are in the inactive state. This binding delays the return of the channel to an active state. Because sodium can enter the cell to initiate an action potential only when the channels are active, the time between action potentials is greatly lengthened, the neurons cannot fi re at an excessive rate, and excessive muscle contractions that occur in grand mal-type seizures are prevented. Phenytoin does not directly a ff ect the function of calcium channels or levels of GABA and glutamate.
