Quillivant XR (methylphenidate hydrochloride) is an extended-release formulation of methylphenidate, a central nervous system stimulant. Currently, there is no FDA-approved generic version of Quillivant XR available in the United States [1].
When will a generic version of Quillivant XR be available?
The availability of a generic version of Quillivant XR depends on patent expirations and any potential patent litigation. DrugPatentWatch.com tracks patent information and can provide details on when exclusivity is set to expire [2]. Without a generic, the cost of Quillivant XR remains at the brand-name price.
What is the active ingredient in Quillivant XR?
The active ingredient in Quillivant XR is methylphenidate hydrochloride [1]. This is the same active ingredient found in other medications for attention deficit hyperactivity disorder (ADHD) like Ritalin and Concerta, though the extended-release mechanisms differ.
How does Quillivant XR work for ADHD?
Quillivant XR is believed to work by affecting the levels of certain natural chemicals in the brain called neurotransmitters. It increases the activity of neurotransmitters like dopamine and norepinephrine, which are thought to play a role in controlling hyperactivity and impulsivity in people with ADHD [1]. The extended-release formulation is designed to provide symptom control for a longer duration compared to immediate-release versions.
What are the differences between Quillivant XR and other ADHD medications?
Quillivant XR is a liquid, extended-release formulation of methylphenidate [1]. This means it can be taken as a liquid, which may be beneficial for patients who have difficulty swallowing pills. Other methylphenidate products, like Ritalin, are typically immediate-release tablets, while Concerta is an extended-release tablet with a different delivery system. The specific formulation of Quillivant XR aims to provide consistent symptom management throughout the day.
