One drug, felbamate, has recently been released, while the other three are expected to be available within 5 years. Anticonvulsants can cause a variety of side effects; some adverse reactions can increase the risk of falls. The medication will also be carefully considered before being prescribed when a patient is nursing (breastfeeding). There are three main pharmacological effects of antiseizure medications. Quick NCLEX review going over Anticonvulsant Seizures Interventions Pharmacology.For more NCLEX reviews, please visit www.allnursingnotes.com Phenytoin is metabolized by hepatic cytochrome P450 enzymes, so it is susceptible to inhibitory drug interactions, which may produce significant increases in circulating phenytoin concentrations and enhance the risk of drug toxicity. Patients should avoid alcohol and other CNS depressants while taking anticonvulsant drug therapy. 7. The use of anticonvulsants is not discontinued in pregnant women with a history of major seizures because of the danger of precipitating status epilepticus. Nursing Considerations Assess Vital signs 15 min after IV dose. This article reviews the background of anticonvulsant drug interactions, the most common interactions encountered, and nursing interventions useful in monitoring potential interactions. Phenytoin improves evidence of seizures by interfering with sodium channels in the brain, resulting in a reduction of sustained high-frequency neuronal discharges. Plasma levels can gradually decrease during pregnancy and should be monitored closely. Antihyperten-sives or other CNS stimulants could potentiate the vasoconstrictive action of methylphenidate. Monitor patient carefully during dose adjustments and promptly report presence of adverse effects. NCLEX Prep. It is not uncommon for patients to require more than one anticonvulsant to control seizures on a long-term basis. Although any pharmacological agent can be involved in a drug interaction, anticonvulsants are often implicated.

Fall precautions should be considered. Since nurses p … The nurse plans to implement additional fall precautions for this patient. Phenytoin acts as an anticonvulsant by increasing efflux or decreasing influx of sodium ions across cell membranes in the motor cortex during generation of nerve impulses; thus stabilising neuronal membranes and decreasing seizure activity. 2. When used as a muscle relaxant, assess patient's muscle spasms, associated pain, and range of motion to help document drug efficacy. Why are additional fall precautions needed? Second, they limit the spread of a seizure discharge from its origin by suppressing the transmission of impulses from one nerve to the next. Monitor plasma levels for pregnant women. Clinical pharmacokinetics of anticonvulsants. If these symptoms occur, they should be immediately reported to the provider. Phenytoin is indicated for the treatment of tonic-clonic (grand mal) and psychomotor (temporal lobe) seizures and for the prevention and treatment of seizures occurring during or following neurosurgery. These drugs prevent seizures but do not provide a cure. Patients should not take gabapentin within 2 hours of antacid medications. The most common adverse reactions encountered with phenytoin therapy are nervous system reactions and are usually dose-related. Ginkgo (Ginkgo biloba) is one of the oldest living tree species. (2020). Antiepileptic drugs should not be abruptly discontinued because of the possibility of increasing seizure frequency. Precautions and considerations for taking Tramadol .

Serum levels of phenytoin sustained above the therapeutic range may produce confusional states referred to as delirium, psychosis, or encephalopathy. There are many types of medications used to treat seizures such as phenytoin, phenobarbital, benzodiazepines, carbamazepine, valproate, and levetiracetam.[1]. Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), also known as multiorgan hypersensitivity, has been reported in patients taking antiepileptic drugs, including gabapentin. Levetiracetam is indicated as adjunctive therapy in the treatment of partial onset seizures in patients 12 years of age and older with epilepsy. Patients should be advised neither to drive a car nor to operate other complex machinery until they have gained sufficient experience on gabapentin to gauge whether or not it affects their mental and/or motor performance adversely.[10].

Note: Answers to the Critical Thinking activities can be found in the “Answer Key” sections at the end of the book. The exact mechanism of action is unknown. First, they increase the threshold of activity in the motor cortex, thus making it more difficult for a nerve to become excited. Anticonvulsants are used to ↓ the incidence and severity of seizures due to various etiologies. Third, they decrease the speed of the nerve impulse conduction within a given neuron. 4. drug therapy. Urine output should remain 30 ml/hr or more, if less notify physician. Research suggests an association between the use of anticonvulsants by pregnant women with epilepsy and an increased incidence of birth defects. Optimal treatment may involve single-drug regimens, but multiple agents are often required.
