LuciViga 500mg, Vigabatrin Tablets

LuciViga 500mg contains Vigabatrin, an antiepileptic medication used primarily to treat seizures. It is especially beneficial for patients who do not respond to first-line therapies. Developed as a second-generation antiepileptic, LuciViga plays a critical role in managing epilepsy, particularly infantile spasms and refractory complex partial seizures.

Vigabatrin has a unique mechanism of action that distinguishes it from other anti-seizure medications, making it a valuable addition to seizure management protocols.

What is LuciViga 500mg?

LuciViga 500mg is a prescription medicine that contains Vigabatrin, an antiepileptic agent. It is primarily used to treat:

• Children’s infantile spasms (ages two months to two years)
• Refractory complex partial seizures in adults and children over 10 years who have not responded to other treatments
• It is not a first-line drug but is recommended when other medications fail to provide adequate seizure control.

How It Works / Mechanism of Action

Vigabatrin works against epilepsy by permanently blocking the GABA transaminase (GABA-T) enzyme. This is how it operates:

• In the central nervous system, GABA (gamma-aminobutyric acid) is the main inhibitory neurotransmitter.
• Normally, the enzyme GABA-T breaks down GABA.
• Vigabatrin blocks this enzyme, leading to increased levels of GABA in the brain.
• Elevated GABA activity inhibits abnormal electrical activity, thereby reducing the frequency and intensity of seizures.
• This mode of action is different from many other antiepileptic drugs, offering a novel pathway for controlling seizures.

How to Use / Indications

LuciViga is indicated for:

• Infantile Spasms (IS) – As monotherapy in children between 2 months and 2 years old.
• Refractory Complex Partial Seizures (CPS) – As adjunctive therapy in adults and children (10 years and older) when other treatments have failed.
• It should always be used under the supervision of a neurologist or epilepsy specialist due to the potential for serious side effects.
