Potiga is prescribed in combination with other medications to help control partial-onset seizures in people age 18 and older. This medicine is thought to work by opening up potassium channels in the brain and preventing abnormal activity from spreading to other parts of the brain. In some cases, a healthcare provider may recommend using Potiga off-label to treat other types of seizures.
What Is Potiga Used For?Potiga™ (ezogabine) is a prescription seizure medication. Specifically, it is approved for use in combination with other seizure medications to treat partial-onset seizures in adults age 18 and older.
There are over 30 different types of seizures a person with epilepsy may experience. These seizures are generally classified into two main categories: partial-onset seizures (also known as focal seizures or simply partial seizures) and generalized seizures.
Partial seizures occur in just one part of the brain. Two types of partial-onset seizures are:
- Simple partial seizures, in which a person will remain conscious but experiences unusual feelings or sensations that can take many forms.
- Complex partial seizures, in which a person has a change or loss of consciousness. People having a complex partial seizure may display strange, repetitious behaviors such as blinks, twitches, mouth movements, or even walking in a circle.
A seizure can start out as a partial seizure before turning into a generalized seizure (this is known as secondary generalization). Generalized seizures are a result of abnormal brain activity on both sides of the brain. These seizures may cause loss of consciousness, falls, or massive muscle spasms. The two most common forms are absence seizures (also known as petit mal seizures) and tonic-clonic seizures (grand mal seizures).
As is typical with new seizure medications, Potiga is not to be used alone, as it has not been adequately studied for such use. In studies, people were given either Potiga or a placebo (a "sugar pill" that does not contain any active ingredients) to take in addition to their usual seizure medications (it would be unethical to give a person with epilepsy just a placebo without the other medications).
