Adderall XR's active ingredients are mixed amphetamine salts [1]. This formulation contains four different amphetamine salts: dextroamphetamine saccharate, dextroamphetamine sulfate, amphetamine aspartate monohydrate, and amphetamine sulfate [1][2]. These salts work together to increase the levels of certain neurotransmitters in the brain, primarily dopamine and norepinephrine [3].
What is the difference between Adderall IR and Adderall XR?
Adderall XR is an extended-release (XR) formulation, meaning it is designed to release its active ingredients gradually over a longer period [4]. In contrast, Adderall immediate-release (IR) releases its medication quickly after administration [4]. This difference in release mechanism affects how often the medication needs to be taken and how its effects are sustained throughout the day.
How do amphetamine salts work in the body?
The mixed amphetamine salts in Adderall XR are central nervous system stimulants [3]. They work by affecting the balance of neurotransmitters in the brain, specifically by increasing the availability of dopamine and norepinephrine [3]. These neurotransmitters play roles in attention, focus, and impulse control.
