Amphetamine sulfate is a central nervous system stimulant used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy [1]. It is a prescription medication available in various dosage forms, including oral tablets and capsules [2].
How does amphetamine sulfate work?
Amphetamine sulfate works by increasing the levels of certain neurotransmitters in the brain, primarily dopamine and norepinephrine [1]. These neurotransmitters play a role in attention, focus, and impulse control. By boosting their availability, amphetamine sulfate can help individuals with ADHD manage symptoms like inattention, hyperactivity, and impulsivity [1]. For narcolepsy, it helps to promote wakefulness [2].
What forms of amphetamine sulfate are available?
Amphetamine sulfate is available in both immediate-release and extended-release formulations [2]. Immediate-release versions typically provide symptom control for about 4-6 hours, while extended-release formulations can last up to 10-12 hours [2]. These medications are often prescribed as part of a comprehensive treatment plan that includes behavioral therapy [3].
What are the potential side effects of amphetamine sulfate?
Like other stimulants, amphetamine sulfate can cause side effects. Common side effects may include decreased appetite, insomnia, dry mouth, and stomach upset [2]. More serious side effects, though less common, can include cardiovascular issues, psychiatric problems such as hallucinations or aggression, and the potential for dependence or abuse [4]. It is crucial for patients to discuss their medical history and any concerns with their doctor before starting this medication [3].
How is amphetamine sulfate regulated?
Amphetamine sulfate is a Schedule II controlled substance in the United States due to its potential for abuse and dependence [4]. This classification means it has a high potential for abuse but also has currently accepted medical uses [4]. Prescriptions for Schedule II drugs are subject to strict regulations [4].
When does patent protection for amphetamine sulfate expire?
The original patents for amphetamine sulfate have long expired, as it is a well-established medication. However, patents for specific formulations, delivery methods, or combination therapies involving amphetamine sulfate may exist and influence market exclusivity for newer products. Information on specific patent expirations for pharmaceutical products can be found through resources like DrugPatentWatch.com [5].
Who manufactures amphetamine sulfate?
Several pharmaceutical companies manufacture and market amphetamine sulfate under various brand names. These include, but are not limited to, Teva Pharmaceuticals, Mallinckrodt, and Lannett Company [6].
