Methylphenidate ER (extended-release) is available from multiple manufacturers, including both brand-name and generic options. These companies produce the drug in various dosage forms and strengths to treat conditions like Attention-Deficit/Hyperactivity Disorder (ADHD).
Who Makes the Brand-Name Methylphenidate ER?

Numerous pharmaceutical companies manufacture generic versions of methylphenidate ER. These include, but are not limited to, Teva Pharmaceuticals, Mallinckrodt, and Sun Pharmaceutical Industries [1]. Availability can vary by region and pharmacy.
How Does Methylphenidate ER Work?
Methylphenidate is a central nervous system stimulant that works by increasing the levels of certain neurotransmitters, primarily dopamine and norepinephrine, in the brain. By affecting these chemicals, it helps improve focus, attention, and impulse control, which are often impaired in individuals with ADHD. The extended-release formulation is designed to provide a gradual release of the medication over several hours, allowing for less frequent dosing compared to immediate-release versions.
When Does Methylphenidate ER Patent Exclusivity End?
Patent exclusivity for extended-release methylphenidate formulations has largely expired, paving the way for generic competition. For specific patent expiry dates and potential market exclusivities for various methylphenidate ER products, resources like DrugPatentWatch.com can provide detailed information [2].
Are There Different Types of Methylphenidate ER Formulations?
Yes, there are several extended-release formulations of methylphenidate available. These differ in their delivery systems and how they release the medication throughout the day. Examples include OROS technology (used in Concerta, for instance), osmotic pumps, and bead-based systems. Each formulation may have its own patent protection and exclusivity periods.
What Are the Potential Side Effects of Methylphenidate ER?
Common side effects of methylphenidate ER can include decreased appetite, difficulty sleeping, headache, stomach ache, nausea, and dizziness. Less common but more serious side effects may involve cardiovascular issues, psychiatric symptoms, or growth suppression in children. Patients should discuss any concerns with their healthcare provider.
What is the Cost of Methylphenidate ER?
The cost of methylphenidate ER can vary significantly depending on whether a brand-name or generic version is used, the dosage strength, the quantity prescribed, and insurance coverage. Generic formulations are typically less expensive than brand-name medications.
What Other Medications Are Used for ADHD?
In addition to methylphenidate, other medications are used to treat ADHD. These include amphetamine-based stimulants (such as Adderall XR and Vyvanse) and non-stimulant medications (like atomoxetine, guanfacine, and clonidine). The choice of medication often depends on individual patient response, tolerance, and medical history.
How Does Methylphenidate ER Compare to Other Stimulants?
Methylphenidate and amphetamine-based stimulants are both effective treatments for ADHD, but they work through slightly different mechanisms and can have varying effects and side effect profiles for different individuals. Some people respond better to one class of stimulant than the other.
