1. How does Vigabatrin work?
Vigabatrin irreversibly inhibits the enzyme that causes the metabolism of GABA in the brain. This action causes an increase in the concentration of GABA in the brain. Vigabatrin ultimately works by decreasing the transmission of abnormal electrical impulses of the brain, thus reducing the intensity and the frequency of seizures in people suffering from epilepsies.
2. Is Vigabatrin Cyp2E1 inhibitor?
Clinical studies conducted so far have indicated that Vigabatrin has neither an inhibitory effect nor an enzyme-inducing effect on the human body. Vigabatrin remains unchanged throughout its metabolism and is excreted mainly in its original form by the kidneys.
3. Why does Vigabatrin cause vision loss?
Vigabatrin causes depletion of an enzyme called taurine, which is essential for the proper functioning and health of the eye's retina. Due to the lack of taurine, there is irreversible damage or atrophy of the retinal nerve fibres. To know more about the side effects of Vigabatrin, consult our specialist; click here.
