Amphetamine sulfate is a central nervous system stimulant used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy [1]. It is available in both immediate-release and extended-release formulations [2].
How does amphetamine sulfate work?
Amphetamine sulfate increases the levels of certain neurotransmitters in the brain, primarily dopamine and norepinephrine. These neurotransmitters play a role in attention, focus, and impulse control. By affecting these brain chemicals, amphetamine sulfate can help improve concentration and reduce hyperactive and impulsive behaviors in individuals with ADHD [1]. For narcolepsy, it helps combat excessive daytime sleepiness [2].
What are the different forms of amphetamine sulfate?
Amphetamine sulfate is available in several forms, including oral tablets and capsules [2]. These formulations can be immediate-release, providing effects relatively quickly, or extended-release, designed to provide a longer duration of action throughout the day [3].
What are the side effects of amphetamine sulfate?
Common side effects of amphetamine sulfate include decreased appetite, dry mouth, weight loss, insomnia, stomach pain, nausea, dizziness, and increased blood pressure [1]. Less common but more serious side effects can include cardiovascular problems such as heart attack and stroke, psychiatric issues like hallucinations and mania, and growth suppression in children [2].
When do patents for amphetamine sulfate expire?

However, patents for specific formulations, such as extended-release versions or combination products, may have different expiration dates [4]. For detailed information on specific patent expirations, DrugPatentWatch.com provides a comprehensive database [4].
What is the difference between amphetamine sulfate and other ADHD medications?
Amphetamine sulfate belongs to a class of stimulant medications. Other stimulant medications for ADHD include methylphenidate and amphetamine mixed salts. Non-stimulant medications are also available, such as atomoxetine and guanfacine. The choice of medication depends on individual patient needs, response to treatment, and potential side effects [1]. Amphetamine sulfate is a single-isomer amphetamine salt, whereas Adderall, for example, is a mixture of amphetamine salts [5].

How is amphetamine sulfate regulated?
Amphetamine sulfate is a Schedule II controlled substance in the United States, indicating a high potential for abuse but also accepted medical uses [6]. This classification subjects it to strict regulations regarding prescribing, dispensing, and manufacturing to prevent diversion and misuse [2][6].
What clinical data supports the use of amphetamine sulfate?
Clinical trials have demonstrated the efficacy of amphetamine sulfate in improving symptoms of ADHD and narcolepsy. Studies typically assess improvements in attention span, impulse control, and reduction in sleepiness [1][2].
What are patient concerns regarding amphetamine sulfate?
Patients often express concerns about side effects, particularly appetite suppression and sleep disturbances. Worries about the potential for addiction and the long-term effects of stimulant use, especially in children, are also common [1][2].
