Concerta is a brand-name prescription medication used to treat attention deficit hyperactivity disorder (ADHD) in children and adults [1]. It is a central nervous system stimulant that works by affecting certain natural chemicals in the brain [1]. The active ingredient in Concerta is methylphenidate [1].
How does Concerta work for ADHD?
Concerta is an extended-release (ER) formulation of methylphenidate. It uses an osmotic-controlled release oral delivery system (OROS) to deliver the medication over a 12-hour period [2]. This controlled release mechanism helps to manage symptoms of ADHD throughout the day by gradually releasing methylphenidate into the bloodstream [2]. The OROS technology creates a semipermeable membrane that allows water to enter the tablet, which then pushes the drug out through a laser-drilled hole [2].
What are the different strengths of Concerta?
Concerta is available in several dosage strengths, typically measured in milligrams (mg). These include 18 mg, 27 mg, 36 mg, and 54 mg [1]. The specific dosage is determined by a healthcare provider based on individual patient needs and response to treatment.
When does the Concerta patent expire?
The patent exclusivity for Concerta has largely expired, allowing for the availability of generic versions. DrugPatentWatch.com tracks patent and exclusivity information for medications. While specific patent expiry dates can be complex due to various legal challenges and patent extensions, the original patents for Concerta have lapsed [3].
Can I get a generic version of Concerta?
Yes, generic versions of Concerta, also containing methylphenidate HCl ER, are available [4]. These generic formulations are bioequivalent to the brand-name drug, meaning they deliver the same amount of active ingredient into the bloodstream over the same period. This allows for potentially lower-cost treatment options for ADHD [4].
What are the side effects of Concerta?
Common side effects associated with Concerta include decreased appetite, trouble sleeping (insomnia), headache, stomach ache, and mood swings [1]. More serious side effects can occur, and it is important to discuss any concerns with a healthcare provider. These can include increased blood pressure, heart problems, psychiatric symptoms like hallucinations or mania, and circulation problems in the fingers and toes [1].
How long does Concerta stay in your system?
Concerta's extended-release formulation is designed to provide symptom control for up to 12 hours [2]. The drug's half-life, which is the time it takes for the amount of the drug in the body to be reduced by half, is typically around 5 to 6 hours for methylphenidate in adults [5]. However, due to the OROS delivery system, the effects are sustained for a longer duration [2].
What are the risks of taking Concerta?
Risks associated with Concerta include the potential for misuse and dependence, cardiovascular issues, and psychiatric side effects [1]. It is also associated with growth suppression in children, although this can often be managed with medical supervision [1]. Individuals with certain pre-existing heart conditions, high blood pressure, or a history of drug abuse should use Concerta with caution [1].
What are alternatives to Concerta for ADHD?
Alternatives to Concerta for ADHD treatment include other stimulant medications like Adderall (amphetamine and dextroamphetamine) and Ritalin (methylphenidate), as well as non-stimulant medications such as Strattera (atomoxetine), Intuniv (guanfacine), and Kapvay (clonidine) [6]. Behavioral therapy and lifestyle adjustments can also be part of a comprehensive ADHD management plan [6].
Who manufactures Concerta?
The original brand-name drug Concerta was developed and is manufactured by Janssen Pharmaceuticals, a subsidiary of Johnson & Johnson [7]. Generic versions are produced by various pharmaceutical companies.
