Final answer:
Vigabatrin inhibits the reuptake of GABA in the brain, reducing abnormal electrical activity and preventing seizures. It is used to treat epilepsy, especially infantile spasms, and refractory partial seizures. However, it can cause visual field defects, behavioral changes, and sleep disturbances as side effects.
Step-by-step explanation:
Vigabatrin is an antiepileptic drug that works by inhibiting the reuptake of the neurotransmitter gamma-aminobutyric acid (GABA) in the brain. By increasing GABA levels, it helps to reduce abnormal electrical activity and prevent seizures.
It is primarily used in the treatment of epilepsy, specifically for seizures associated with infantile spasms, and as an adjunctive therapy for refractory partial seizures.
However, Vigabatrin is associated with some potential side effects, including visual field defects, behavioral and psychiatric changes, and sleep disturbances. Regular monitoring is necessary to detect these side effects.
