* 1/4 dextroamphetamine saccharate
* 1/4 dextroamphetamine sulfate
* 1/4 (racemic dextro/laevo-amphetamine) aspartate monohydrate
* 1/4 (racemic dextro/laevo-amphetamine) sulfate
These four salts are metabolized at different rates and possess diverse half lives, therefore resulting in a less dramatic onset and termination of therapeutic action; as compared to single salt amphetamine preparations.
The average elimination half-life in adults for dextroamphetamine and levoamphetamine is 10 hours and 13 hours respectively. Breakdown rates are affected by many factors including urinary and stomach pH, weight, gender, other medications being taken, and age.
Urinary and stomach pH levels can have the strongest effect on (d,l)-amphetamine excretion and absorption. Co-administration of acidic substances (e.g. citric acid) causes an accelerated excretion of (d,l)-amphetamine while co-administration of alkaline agents (e.g. antacids) causes a marked increase in both retention and absorption of amphetamines potentially resulting in dangerously high serum amphetamine levels. buy Adderall
Adderall's effects are similar to other CNS stimulants of the same class and preparation (see amphetamine for details).
