TENUATE vs TEPANIL
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.
TEPANIL (diethylpropion) is a sympathomimetic amine that acts as a norepinephrine reuptake inhibitor in the hypothalamus, increasing norepinephrine levels in the synaptic cleft, which stimulates beta-2 adrenergic receptors, leading to appetite suppression.
