Horizant, the brand name for gabapentin enacarbil, is not classified as a controlled substance [1].
Why is Horizant not considered a controlled substance?
Controlled substances are drugs that have the potential for abuse or addiction and are regulated by federal law. Horizant, a prodrug of gabapentin, works by affecting chemicals and nerves in the body that are involved in causing seizures and some types of pain [1]. It is prescribed for moderate-to-severe primary restless legs syndrome and postherpetic neuralgia [1].
What is the difference between Horizant and other gabapentin products?
Horizant is an extended-release formulation of gabapentin enacarbil, which is converted to gabapentin in the body [1]. This differs from immediate-release gabapentin products, which are available generically and have been on the market for longer [2]. The extended-release nature of Horizant allows for less frequent dosing.
When does the patent for Horizant expire?
Drug patent information can be complex and involve multiple patents covering different aspects of a drug.

What are the side effects of Horizant?

It is crucial for patients to inform their doctor about all medications they are taking to avoid potential interactions or additive side effects.

For postherpetic neuralgia, the dosage is also 600 mg taken once daily [1]. Dosing may be adjusted by a healthcare professional based on individual patient response and tolerability.
