In medicine, anticonvulsants are medications "used to prevent seizures or reduce their severity."[1] A number of the drugs have additional applications in pain management or in psychiatry.
Pharmacologic classes
There are three main mechanisms of action:[2]
- Limiting the sustained firing of neurons, by promoting the inactive state of voltage-gated sodium channels
- Enhanicing the effectiveness of gamma-aminobutyric acid (GABA) mediation of synaptic inhibition
- Limiting action of a specific voltage-gated calcium channel
Adverse effects
Anticonvulsants may increase risk of suicide.[3]
