Anticonvulsants suppress the excessive rapid firing of neurons during seizures. [6] Anticonvulsants also prevent the spread of the seizure within the brain. [7] Conventional antiepileptic drugs may block sodium channels or enhance γ-aminobutyric acid function. Several antiepileptic drugs have multiple or uncertain mechanisms of action. [8]
Interaction studies have been conducted with a number of common anticonvulsants. Carbamazepine reduces blood plasma concentrations of eslicarbazepine, probably because it induces glucuronidation. This drug combination also increased the risk for diplopia, impaired coordination and dizziness in a clinical study.
[citation needed] Bemegride and flumazenil are used to treat drug overdoses (of barbiturates and benzodiazepines respectively), but may cause convulsions if the dose is too high. [8] [9] Convulsants are also widely used in scientific research, for instance in the testing of new anticonvulsant drugs. Convulsions are induced in captive animals ...
Lamotrigine has fewer drug interactions than many anticonvulsant drugs, although pharmacokinetic interactions with carbamazepine, phenytoin and other hepatic enzyme-inducing medications may shorten half-life. [84] Dose adjustments should be made on clinical response, but monitoring may be of benefit in assessing compliance. [5]
Stiripentol, sold under the brand name Diacomit, is an anticonvulsant medication used for the treatment of Dravet syndrome - a serious genetic brain disorder. [5] [6]The most common side effects include loss of appetite, weight loss, insomnia (difficulty sleeping), drowsiness, ataxia (inability to co‑ordinate muscle movements), hypotonia (low muscle strength) and dystonia (muscle disorders).
Generally, drugs outlined within the ATC code N03 should be included in this category. Please see WP:PHARM:CAT for more information. Wikimedia Commons has media related to Anticonvulsants .
Valproate has a broad spectrum of anticonvulsant activity, although it is primarily used as a first-line treatment for tonic–clonic seizures, absence seizures and myoclonic seizures and as a second-line treatment for partial seizures and infantile spasms.
Nitrazepam therapy, compared with other drug therapies, increases risk of death when used for intractable epilepsy in an analysis of 302 patients. The risk of death from nitrazepam therapy may be greater in younger patients (children below 3.4 years in the study) with intractable epilepsy.
