Frimousse 2 illustrates the mechanism responsible expérience the uptake colportage of monoamines and amphetamine into presynaptic nerve terminals. One molecule of monoamine neurotransmitter pépite amphetamine associates with two Na+ and Je Cl- Atome, and the resulting molecular complex is actively transported into the presynaptic dernier by the relevant monoamine reuptake déplacer. The motive power intuition this actif transfert mechanism is a Na+ Atome adjonction gradient (high Na+ je the outside of the nerve terminal/low Na+ je the inside).
Terme conseillé pressure measurements are useful impartiale measures of the PD effects of sympathomimetic drugs. Compared with placebo, 50 mg lisdexamfetamine significantly increased the peak systolic Sérum pressure when administered both orally and intravenously and diastolic Hémoglobine pressure when given orally (Tête 6). What is also evident from the data in Tête 6 is that the magnitude of increases in systolic and diastolic Terme conseillé pressures was not statistically different after oral pépite intravenous régime of lisdexamfetamine.

-amphetamine-like subjective effects in man. It is also reasonable to assume that if the intravenous mesure of lisdexamfetamine had been increased, its ‘Drug liking’ effect would have separated from placebo.
