Methamphetamine - oral (i.e., tablets or capsules), intravenous injection, smoking, and intranasal (i.e., snorting). Metabolism and Excretion. Nearly half of a methamphetamine dose is recovered from urine unchanged. A small percentage is demethylated to amphetamine and its metabolites.

Methamphetamine is excreted in the urine in both the unchanged form and as the primary metabolite, amphetamine. Detection of amphetamines in urine is extremely dependent on urine pH, with alkaline conditions slowing excretion and acidic conditions increasing it.

The AMPH assay provides a rapid screening procedure for determining the presence of amphetamines (AMPH) and its metabolites in urine. This test provides only a preliminary analytical result; a positive result by this assay should be confirmed by another generally accepted non-immunological method such as thin layer chromatography (TLC), gas ...

Amphetamine is metabolized to deaminated (hippuric and benzoic acids) and hydroxylated metabolites. Methamphetamine is partially metabolized to amphetamine, its major active metabolite.3 Amphetamines appear in the urine within three hours after any type of administration4, and can be detected by this Emit( assay for as long as 24-48 hours after ...

Amphetamine is largely inactivated by the liver yielding metabolites, which hydroxylate and deaminate the compounds, while some unchanged amphetamine is excreted in the urine (5). Methamphetamine is also excreted to some extent unchanged, but major metabolites of methamphetamine are amphetamine and oxidized deaminated derivative (5).

In the EMIT II platform, medications—such as ranitidine and drug metabolites of compounds, such as chlorpromazine and bupropion—can cross-react in the amphetamine assay.6,7 Therapeutic concentrations of the fluoroquinolone antibiotics, ofloxacin and levofloxacin, can interfere in the EMIT II opioid assay.4
