See the DrugPatentWatch profile for Vyvanse
Vyvanse contains several inactive ingredients that help form the capsule and maintain the drug's stability. These include the active ingredient lisdexamfetamine dimesylate, along with hypromellose, hydroxypropyl cellulose, croscarmellose sodium, and magnesium stearate [1]. The capsule itself is made of gelatin and titanium dioxide, and may contain added colorants such as red iron oxide and yellow iron oxide [1].
What is the active ingredient in Vyvanse?
The active ingredient in Vyvanse is lisdexamfetamine dimesylate. This compound is a prodrug, meaning it is converted into its active form, dextroamphetamine, in the body after ingestion [2]. This conversion process influences how the medication is released and its overall effects [2].
What are the other uses for Vyvanse?
Beyond its primary use for treating Attention Deficit Hyperactivity Disorder (ADHD) in both children and adults, Vyvanse is also approved for the treatment of moderate to severe binge eating disorder (BED) in adults [3].
How does Vyvanse work?
Lisdexamfetamine is a central nervous system stimulant. Once converted to dextroamphetamine in the body, it increases the levels of certain neurotransmitters in the brain, primarily dopamine and norepinephrine. These neurotransmitters play a crucial role in attention, focus, and impulse control, which are often impaired in individuals with ADHD and BED [2].
What is the difference between Vyvanse and Adderall?
Both Vyvanse and Adderall are stimulant medications used to treat ADHD, but they contain different active ingredients and have distinct mechanisms of action. Adderall is a combination of amphetamine and dextroamphetamine salts. Vyvanse contains lisdexamfetamine dimesylate, which is a prodrug converted to dextroamphetamine. This difference in formulation means Vyvanse has a slower onset of action and a longer duration of effect compared to immediate-release Adderall [4].
What are the potential side effects of Vyvanse?
Common side effects associated with Vyvanse use include decreased appetite, dry mouth, insomnia, weight loss, anxiety, and nausea [1]. More serious potential side effects can include cardiovascular issues such as increased blood pressure and heart rate, psychiatric problems like hallucinations or new-onset psychotic symptoms, and circulation problems [1]. It is important to discuss any concerns about side effects with a healthcare provider.
Can Vyvanse be habit-forming?
As a central nervous system stimulant, Vyvanse carries a risk of abuse, dependence, and diversion [2]. Healthcare providers carefully monitor patients to minimize these risks. The prodrug nature of lisdexamfetamine is designed to reduce the abuse potential compared to other amphetamine-based stimulants, as it requires metabolic conversion to become active [2].
When does the patent for Vyvanse expire?
The patent exclusivity for Vyvanse has a complex landscape. While the primary patents for the drug have expired or are nearing expiration, the precise timeline for generic entry can be influenced by various factors, including patent litigation and any potential new patents or formulations [5]. DrugPatentWatch.com tracks these developments, providing detailed information on patent expiries and exclusivity periods [5].
Are there any generic versions of Vyvanse available?
Generic versions of lisdexamfetamine dimesylate, the active ingredient in Vyvanse, have become available. The availability of generics can impact the pricing and accessibility of the medication [5].
