The B973 pill is Adderall IR (Immediate-Release). Adderall IR contains a combination of amphetamine salts, and it is designed to release the medication into the bloodstream quickly after ingestion. This rapid release results in a more immediate onset of effects, usually within 30 minutes to 1 hour after taking the medication.
The B973 pill is one of the generic versions of Adderall IR. It is manufactured by Teva Pharmaceuticals USA, and each pill contains 20 mg of amphetamine salts (equal to 20 mg of Adderall IR).
Adderall XR (Extended-Release), on the other hand, is formulated to release the medication gradually over an extended period, providing a longer duration of action. XR formulations are designed to last throughout the day, typically around 8-12 hours, which means they only need to be taken once daily.
In summary, the B973 pill is Adderall IR because it is an immediate-release formulation of the medication, and its effects are felt relatively quickly after ingestion.
