id="_Diethylpropion_OVERVIEW_">OVERVIEW</h2><div id="Diethylpropion.Introduction"><h3>Introduction</h3><p>Diethylpropion is a sympathomimetic amine and anorectic agent used for the short-term therapy of obesity. Diethylpropion has not been linked to either serum enzyme elevations or to clinically apparent acute liver injury.</p></div><div id="Diethylpropion.Background"><h3>Background</h3><p>Diethylpropion (dye eth" il proe' pee on) is a structural analogue to amphetamine and has similar activity in suppressing appetite, but has few of the other central nervous system effects of amphetamines and less abuse potential. Diethylpropion was approved as a therapy for obesity in the United States in 1959 and is recommended only for short term use (less than 12 weeks). Diethylpropion is available by prescription as 25 mg immediate release and 75 mg controlled release tablets in generic forms and formerly under the trade name Tenuate. The usual dose is 75 mg daily either as 25 mg (immediate release) 1 hour before meals or 75 mg (controlled release) once daily. Diethylpropion is a Schedule IV controlled substance, meaning that it has a proven but low potential for abuse and has an accepted medical use. Common side effects include nervousness, excitability, insomnia, headache, dry mouth, sweating, nausea, constipation, and thirst. Rare severe adverse events include atrial fibrillation, acute psychosis and pulmonary hypertension.</p></div><div id="Diethylpropion.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>Diethylpropion has not been linked to an increased rate of serum enzyme elevations during therapy; however, actual results of ALT monitoring during diethylpropion therapy have rarely been reported. Despite long term availability and wide use of diethylpropion, there have been no published reports linking it to clinically apparent acute liver injury.</p><p>Likelihood score: E (unlikely cause of clinically apparent liver injury).</p></div><div id="Diethylpropion.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The safety of diethylpropion is perhaps due to its rapid urinary excretion. Nevertheless, it is extensively metabolized in the liver and some of the metabolites are biologically active.</p><p>Drug Class: <a href="/books/n/livertox/WeightLossAgents/?report=reader">Weight Loss Agents</a></p></div></div><div id="Diethylpropion.PRODUCT_INFORMATION_Weigh"><h2 id="_Diethylpropion_PRODUCT_INFORMATION_Weigh_">PRODUCT INFORMATION</h2><div id="Diethylpropion.BPI" class="box boxed-text-box whole_rhythm hide-overflow"><p>
