What is the Difference between Adderall and Vyvanse?
Among the many lists of effective ADHD drugs prescribed by doctors, Adderall and Vyvanse are one of the most popular of them all. These two are also known for having potentially serious side effects, a Schedule II substance, are amphetamine salts, and manufactured by Shire PLC.
Differentiating the two does not mean that the former is more effective than the latter (and vice versa). The thing is Vyvanse is actually Shire’s substitute drug over Adderall. In April of 2009, Shire’s patent over Adderall had expired, and to keep the money flowing steadily, the company has devised a new drug with same purpose only in a different name and packaging that is Vyvanse.
Although similar in various aspects, Vyvanse and Adderall do have some slight differences when compared with each other which includes the following that are listed below,
-Adderall is a mixture of 4 types of d (or dextroamphetamine) and l (or levo) amphetamines; Vyvanse is solely d-amphetamine.
-Adderall is released through bead technology; Vyvanse is released by means of digestion
-Vyvanse has lasting effect and with less side effects like reduced appetite, irritability, headache, dry mouth, insomnia, and nervousness.
-Adderall is believed to be more effective, but with more adverse side effects like anxiety, addiction, increased blood pressure, stroke, and heart attack just to name a few.
-Adderall can be administered in various ways like standard oral administration, parachuting, insuffulation, rectal administration, or through IV/IM injection; Vyvanse is only taken orally but can be dissolved in liquid.
-Vyvanse is quite expensive; Adderall costs less and may come in generic form.
Between the two, Vyvanse (also known as Lisdexamfetamine) is proven to have less potential for abuse or addiction as compared to Adderall that has an active component of dextroamphetamine. The cardiovascular side-effects between the two may be similar to some extent but due to differences in manner of administration, the development of health risks while taking Vyvanse are reduced.
