ADDERALL 7.5 vs CYLERT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ADDERALL 7.5 is a combination of amphetamine and dextroamphetamine, which are non-catecholamine sympathomimetic amines with CNS stimulant activity. The mechanism of action involves blocking the reuptake of norepinephrine and dopamine into presynaptic neurons, as well as increasing their release into the extraneuronal space. This leads to increased levels of these neurotransmitters in the synaptic cleft, enhancing stimulation of postsynaptic receptors.
CNS stimulant; increases extracellular dopamine and norepinephrine levels by blocking their reuptake and enhancing release.
5-20 mg orally 1-3 times daily; immediate-release tablets administered upon awakening and at 4-6 hour intervals as needed; extended-release capsules administered once daily upon awakening; maximum total daily dose 40 mg.
37.5 mg orally once daily in the morning; may increase by 18.75 mg weekly to a maximum of 112.5 mg/day.

The terminal elimination half-life of amphetamine is approximately 10-13 hours in adults, but can vary based on urinary pH (alkaline urine prolongs half-life up to 20 hours; acidic urine reduces it to 7-8 hours). In children, half-life is slightly shorter (6-8 hours). Clinical context: Steady-state is achieved within 2-3 days.
Terminal elimination half-life is 12-30 hours in children (mean 19 hours) and 8-14 hours in adults; the long half-life supports once-daily dosing, but accumulation can occur with repeated dosing
Renal: approximately 90% of a dose is excreted in urine, with about 30% as unchanged amphetamine and the remainder as metabolites (including deaminated and hydroxylated products). Fecal excretion is negligible (<5%).
Primarily renal (80-90% as unchanged drug and metabolites, with 50-60% as unchanged pemoline), minor biliary/fecal elimination (<10%)
