Adderall is a stimulant medication primarily used to treat Attention Deficit Hyperactivity Disorder (ADHD) and narcolepsy. It is a combination of four amphetamine salts: dextroamphetamine saccharate, dextroamphetamine sulfate, amphetamine aspartate monohydrate, and amphetamine sulfate [1]. These amphetamine salts are central nervous system stimulants that affect chemicals in the brain and nerves that cause hyperactivity and impulsivity.
How does Adderall work?
Adderall is believed to work by increasing the levels of certain neurotransmitters in the brain, specifically dopamine and norepinephrine. These neurotransmitters play a role in attention, focus, and impulse control. By increasing their availability, Adderall helps individuals with ADHD manage their symptoms [1].
What are the different formulations of Adderall?
Adderall is available in two main formulations: immediate-release (IR) and extended-release (XR) [2].
* Adderall IR: This formulation is designed to release the medication into the body quickly. It typically starts working within 30 to 60 minutes and its effects last for about 4 to 6 hours [3]. It is usually taken two to three times a day.
* Adderall XR: This formulation is designed to release the medication gradually throughout the day. The capsule contains beads that release the drug in two phases, providing a longer duration of effect, typically 10 to 12 hours [3]. This allows for once-daily dosing.
What is the difference between Adderall IR and XR?
The primary difference lies in their release mechanism and duration of action. Adderall IR provides immediate effects that are shorter-lived, requiring multiple doses per day. Adderall XR offers a sustained release, providing symptom control over a longer period with a single daily dose [2, 3].
Who makes Adderall?
Adderall is manufactured by Shire, a Takeda company [4].
