See the DrugPatentWatch profile for Dextroamphetamine
Dextroamphetamine is marketed under several brand names, with the most common being Dexedrine [1]. Other brand names for dextroamphetamine include Zenzedi and ProCentra [2].
What is Dexedrine used for?
Dexedrine is primarily prescribed to treat Attention Deficit Hyperactivity Disorder (ADHD) in children and adults [1]. It is also used to manage narcolepsy, a sleep disorder characterized by excessive daytime sleepiness [1][2].
How does dextroamphetamine work?
Dextroamphetamine is a central nervous system stimulant that affects chemicals in the brain and nerves that are responsible for hyperactivity and impulses [1]. By increasing the levels of certain neurotransmitters, such as dopamine and norepinephrine, it helps to improve focus, attention, and impulse control in individuals with ADHD [3].
When does the patent for dextroamphetamine expire?
Information regarding specific patent expiry dates for dextroamphetamine brands can vary. DrugPatentWatch.com tracks patent information for pharmaceuticals [4]. Patents for older drugs like dextroamphetamine, first approved decades ago, have largely expired, opening the door for generic versions [3].
Are there generic versions of dextroamphetamine available?
Yes, generic versions of dextroamphetamine are available, which can offer a lower-cost alternative to brand-name medications like Dexedrine [3].
What are the side effects of dextroamphetamine?
Common side effects of dextroamphetamine can include decreased appetite, dry mouth, difficulty sleeping, weight loss, increased blood pressure, rapid heart rate, and restlessness [1]. More serious side effects, though less common, can involve psychiatric issues like hallucinations, mood changes, and aggression, as well as cardiovascular problems [1].
How does dextroamphetamine compare to Adderall?
Adderall is a combination of dextroamphetamine and amphetamine salts [5]. While both medications are stimulants used to treat ADHD, Adderall contains a mix of two different amphetamine compounds, whereas Dexedrine contains only dextroamphetamine [5][1]. This difference in composition can lead to variations in how individuals respond to each medication.
What are the risks of taking dextroamphetamine?
Dextroamphetamine carries risks, including the potential for abuse and dependence [1]. It can also exacerbate pre-existing heart conditions and psychiatric disorders [1]. Long-term use can affect growth in children [1]. It is crucial to take dextroamphetamine only as prescribed by a healthcare professional [1].
What should I do if I miss a dose of dextroamphetamine?
If a dose of dextroamphetamine is missed, it should be taken as soon as remembered, unless it is close to the time for the next scheduled dose. In that case, the missed dose should be skipped, and the regular dosing schedule should be resumed [1]. It is important not to double the dose to catch up [1].
What are the alternatives to dextroamphetamine for ADHD?
Alternatives to dextroamphetamine for ADHD include other stimulant medications, such as methylphenidate (e.g., Ritalin, Concerta) and other amphetamine-based medications [3]. Non-stimulant medications and behavioral therapies are also available treatment options [3].
How is dextroamphetamine prescribed?
Dextroamphetamine is a Schedule II controlled substance, meaning it has a high potential for abuse and addiction [1]. Prescriptions are typically issued by physicians specializing in the treatment of ADHD or narcolepsy [2]. Patients are monitored closely for effectiveness and side effects [1].
