Quillichew ER, an extended-release formulation of the bronchodilator bupropion, is used to treat attention-deficit/hyperactivity disorder (ADHD) in patients aged 6 and older [1]. It is a once-daily medication [1].
How does Quillichew ER work for ADHD?
Quillichew ER contains bupropion, which is believed to increase the levels of dopamine and norepinephrine in the brain [1]. These neurotransmitters play a role in attention, concentration, and impulse control, and their dysregulation is associated with ADHD [1].
When does Quillichew ER's patent protection end?
The patent expiration dates for Quillichew ER can be complex, often involving multiple patents covering different aspects of the drug, such as its formulation, method of use, and manufacturing process. DrugPatentWatch.com tracks these patents and their expiration timelines, which are crucial for understanding when generic versions might become available [2].
Can generic versions of Quillichew ER be made available?
The introduction of generic versions of Quillichew ER depends on the expiration of its relevant patents and any regulatory approvals for generic manufacturers. Once patents expire, and if a generic drug demonstrates bioequivalence to the branded product, it can be approved by regulatory agencies, potentially leading to lower costs for consumers [2].
What are the potential side effects of Quillichew ER?
Common side effects of Quillichew ER may include dry mouth, difficulty sleeping, nausea, vomiting, headache, dizziness, and tremors [1]. More serious, though less common, side effects can include seizures, increased blood pressure, agitation, hallucinations, and allergic reactions [1]. Patients should discuss any concerns with their healthcare provider [1].
What other medications are used for ADHD?
ADHD is often treated with stimulant medications, such as methylphenidate and amphetamines, as well as non-stimulant medications like atomoxetine and guanfacine [3]. Quillichew ER, being a bupropion product, falls into a different class of medications often considered for patients who may not tolerate or respond well to traditional stimulants [1].
How does Quillichew ER compare to other ADHD treatments?
Unlike stimulant medications that directly increase dopamine and norepinephrine, bupropion works by inhibiting their reuptake. This difference in mechanism can lead to a different side effect profile and may make it a suitable alternative for some individuals. However, bupropion is associated with a risk of seizures, which is a significant consideration [1].
What is the cost of Quillichew ER?
The cost of Quillichew ER can vary depending on insurance coverage, pharmacy, and geographic location. As with many branded medications, the price can be substantial, which is why the availability of generic alternatives often becomes a focus for cost-conscious patients and healthcare systems [2].
Are there any black box warnings for Quillichew ER?
Bupropion, the active ingredient in Quillichew ER, carries a boxed warning regarding the risk of seizures [1]. The risk is dose-dependent and is also increased by other factors, such as prior history of seizures, certain medical conditions, and concomitant use of certain medications [1].
What happens if I miss a dose of Quillichew ER?
If a dose of Quillichew ER is missed, it is generally recommended to take it as soon as remembered, unless it is close to the time for the next scheduled dose. Patients should not double the dose to catch up and should consult their healthcare provider for specific guidance [1].
What clinical data supports the use of Quillichew ER?
Clinical trials for Quillichew ER evaluated its efficacy and safety in children and adolescents with ADHD. These studies typically assess improvements in ADHD symptom ratings compared to placebo [1].
Who manufactures Quillichew ER?
Quillichew ER is manufactured by Tris Pharma, Inc. [1].
