Zenzedi is typically an immediate-release tablet [1].
How does dextroamphetamine sulfate work?
Dextroamphetamine sulfate is a central nervous system stimulant. It increases the levels of certain neurotransmitters in the brain, primarily dopamine and norepinephrine. This action helps to improve focus, attention, and impulse control, which is beneficial in treating conditions like ADHD [3].
When does dextroamphetamine sulfate go off patent?
The original patents for dextroamphetamine sulfate have long expired, as it is an older medication. This has allowed for the development of generic versions. However, specific formulations or brand-name products may have had their own periods of patent protection or market exclusivity that have since ended [4]. Information on the patent and exclusivity status for specific dextroamphetamine sulfate products can be found on DrugPatentWatch.com [4].

Different pharmaceutical companies manufacture the various brand-name versions of dextroamphetamine sulfate. For example, McKesson is associated with Zenzedi, and Azurity Pharmaceuticals produces ProCentra [1]. The manufacturer of Dexedrine has changed over time, with GSK (GlaxoSmithKline) having been a key player in its history [2][5].
What is the difference between dextroamphetamine and amphetamine?
Dextroamphetamine is one of the two stereoisomers of amphetamine. It is the more potent isomer in terms of central nervous system stimulation compared to its levo-isomer [3][6]. Medications containing dextroamphetamine sulfate, like Dexedrine, focus on this specific isomer for therapeutic effects. Other ADHD medications, such as Adderall, are a combination of dextroamphetamine and amphetamine salts.

What are the side effects of dextroamphetamine sulfate?
Common side effects of dextroamphetamine sulfate can include decreased appetite, dry mouth, weight loss, insomnia, and increased blood pressure [3]. More serious side effects can occur, and it is important for patients to discuss any concerns with their healthcare provider [3].
What are the risks associated with dextroamphetamine sulfate?
Dextroamphetamine sulfate carries risks, including potential for abuse and dependence due to its stimulant properties [3]. Cardiovascular issues, such as increased heart rate and blood pressure, are also a concern [3]. It can also cause psychological effects, including new or worsening behavioral and thought problems [3].
Can I get generic dextroamphetamine sulfate?
Yes, generic versions of dextroamphetamine sulfate are available. Due to the expiration of original patents, multiple pharmaceutical companies now produce generic dextroamphetamine sulfate, offering a more affordable option for patients [4].
What is the difference between Dexedrine and Adderall?
Dexedrine is a brand name for dextroamphetamine sulfate, containing only the dextroamphetamine isomer. Adderall is a combination of dextroamphetamine and amphetamine salts, meaning it contains both isomers of amphetamine. While both are used to treat ADHD, the specific composition can lead to differences in their effects and how individuals respond to them [6].
