Antikonvulsantteja

Antikonvulsantteja is a term used to describe anticonvulsants, a diverse group of medications designed to prevent seizures in epilepsy and to treat certain other neurological and psychiatric conditions. These drugs act through multiple mechanisms, including stabilization of neuronal membranes by blocking voltage-gated sodium channels, enhancement of GABAergic inhibition, reduction of excitatory glutamatergic transmission, and modulation of calcium channels. The category is often divided into older, traditional agents and newer, second-generation species, with varying spectra of activity against seizure types.

Commonly used anticonvulsants include carbamazepine, valproate, phenytoin, and phenobarbital, alongside newer agents such as lamotrigine, levetiracetam, topiramate, oxcarbazepine, gabapentin, and pregabalin. Some anticonvulsants are broad-spectrum, effective for multiple seizure types, while others are particularly suited to focal seizures. Beyond epilepsy, anticonvulsants are employed for mood stabilization in bipolar disorder, management of neuropathic pain, migraine prevention, and certain other conditions, depending on the drug.

Adverse effects vary by agent but may include sedation, dizziness, cognitive slowing, ataxia, weight changes, rash, liver toxicity, cytopenias, and teratogenic risks (notably with valproate). Drug interactions are common due to hepatic enzyme induction or inhibition, necessitating careful review of concomitant medications. Monitoring often includes clinical assessment, and for several drugs, periodic blood levels, liver function tests, and, in pregnancy, risk counseling and dose adjustments.

Clinical use emphasizes individualized dosing, slow titration, adherence, and regular follow-up to balance seizure control with safety and tolerability.
