TENUATE vs TENUATE DOSPAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Tenuate (diethylpropion) is a sympathomimetic amine that acts as an appetite suppressant. It stimulates the release of norepinephrine and to a lesser extent dopamine from presynaptic nerve terminals in the hypothalamus, increasing satiety.
Releases norepinephrine from nerve terminals in the lateral hypothalamic feeding center, reducing appetite.

4-6 hours (terminal); clinical context: short half-life supports multiple daily dosing
The terminal elimination half-life is approximately 4-6 hours in adults with normal renal function, though clinical effects may last longer due to tissue distribution.
Renal (90% as metabolites, ~10% unchanged); minor biliary/fecal (<10%)
Renal excretion of unchanged drug and metabolites; approximately 85-90% of the dose is excreted in urine within 48 hours, with less than 5% in feces.
