id="Bupropion.Introduction"><h3>Introduction</h3><p>Bupropion is an aminoketone antidepressant that is widely used in therapy of depression and smoking cessation. Bupropion therapy can be associated with transient, usually asymptomatic elevations in serum aminotransferase levels and has been linked to rare instances of clinically apparent acute liver injury.</p></div><div id="Bupropion.Background"><h3>Background</h3><p>Bupropion (bue proe' pee on) is an aminoketone derivative and antidepressant whose mechanism of action is not well understood. Bupropion has no activity against monamine oxidase and only weak inhibition of serotonin and norepinephrine reuptake. It appears to act via noradrenergic or dopaminergic mechanisms. Bupropion was approved for use in moderate and severe depression in the United States in 1985 and was later approved for use in seasonal affective disorder and in aiding smoking cessation. Bupropion is currently in wide use, approximately 4 million prescriptions being filled yearly. Bupropion is available as immediate and sustained release tablets of 75, 100, 150, 200 and 300 mg in several generic forms and under the brand name of Welbutrin. The recommended dosage for depression in adults is 75 to 300 mg daily either twice daily in immediate release forms or once daily in extended or sustained release forms. Separate formulations of sustained release forms are available for smoking cessation in tablets of 150 mg generically and under the brand name Zyban, recommended dosage being 150 to 300 mg daily. Common side effects of bupropion are drowsiness, dizziness, agitation, headahce, nausea, abdominal pain and dry mouth.</p></div><div id="Bupropion.Hepatotoxicity"><h3>Hepatotoxicity</h3><p>Liver test abnormalities have been reported to occur in less than 1% of patients on bupropion, and elevations are usually modest and usually do not require dose modification or discontinuation. Rare instances of acute, clinically apparent episodes of liver injury with marked liver enzyme elevations with or without jaundice have been reported in patients on bupropion (Case 1). The onset of injury is usually within 1 to 3 months and the pattern of serum enzyme elevations has been variable, from hepatocellular to cholestatic. Autoimmune (autoantibodies) are found in a proportion of cases, but in low titer. Immunoallergic features (rash, fever, eosinophilia) are uncommon. The injury is generally self-limited, but fatal cases have been reported.</p><p>Likelihood score: C (probable rare cause of clinically apparent liver injury).</p></div><div id="Bupropion.Mechanism_of_Injury"><h3>Mechanism of Injury</h3><p>The mechanism by which bupropion causes liver injury is not known. Bupropion is extensively metabolized by the liver, mainly via the cytochrome P450 system (CPY2B6), and hepatotoxicity may be mediated by toxic intermediates of their metabolism.</p></div><div id="Bupropion.Outcome_and_Management"><h3>Outcome and Management</h3><p>The serum aminotransferase elevations that occur on bupropion therapy are usually self-limited and do not require dose modification or discontinuation of therapy. Rare instances of acute liver failure and chronic hepatitis have been attributed to bupropion therapy. Persons with intolerance to bupropion may have similar reactions to other antidepressants, and careful monitoring is warranted if other such agents are used.</p><p>Drug Class: <a href="/books/n/livertox/Antidepressants/?report=reader">Antidepressant Agents</a></p></div></div><div id="Bupropion.CASE_REPORT"><h2 id="_Bupropion_CASE_REPORT_">CASE REPORT</h2><div id="Bupropion.Case_1._Acute_liver_injury_due"><h3>Case 1.

He was jaundiced but had no fever or rash. Laboratory tests showed prominent elevations in both serum aminotransferases and alkaline phosphatase and a total bilirubin of 12.1 mg/dL. Bupropion was discontinued and he began to improve (Table). Tests for hepatitis A, B and C were negative. He had low levels of antinuclear antibody (ANA 1:80) and antimitochondrial antibody (AMA 1:80), but no smooth muscle antibody. An abdominal ultrasound showed no evidence of biliary obstruction. Within 3 months of stopping bupropion, serum enzymes and bilirubin levels had returned to baseline; the continued low level abnormal values during long term follow up were attributed to alcohol use. Serum ANA and AMA were negative.</p><div id="Bupropion.Key_Points"><h4>Key Points</h4><div class="iconblock whole_rhythm clearfix ten_col table-wrap" id="figBupropionT1"><a href="/books/NBK548836/table/Bupropion.T1/?report=objectonly" target="object" title="Table" class="img_link icnblk_img figpopup" rid-figpopup="figBupropionT1" rid-ob="figobBupropionT1"><img class="small-thumb" src="/books/NBK548836/table/Bupropion.T1/?report=thumb" src-large="/books/NBK548836/table/Bupropion.T1/?report=previmg" alt="Image " /></a><div class="icnblk_cntnt"><h4 id="Bupropion.T1"><a href="/books/NBK548836/table/Bupropion.T1/?report=objectonly" target="object" rid-ob="figobBupropionT1">Table</a></h4></div></div></div><div id="Bupropion.Laboratory_Values"><h4>Laboratory Values</h4><div class="iconblock whole_rhythm clearfix ten_col table-wrap" id="figBupropionT2"><a href="/books/NBK548836/table/Bupropion.T2/?report=objectonly" target="object" title="Table" class="img_link icnblk_img figpopup" rid-figpopup="figBupropionT2" rid-ob="figobBupropionT2"><img class="small-thumb" src="/books/NBK548836/table/Bupropion.T2/?report=thumb" src-large="/books/NBK548836/table/Bupropion.T2/?report=previmg" alt="Image " /></a><div class="icnblk_cntnt"><h4 id="Bupropion.T2"><a href="/books/NBK548836/table/Bupropion.T2/?report=objectonly" target="object" rid-ob="figobBupropionT2">Table</a></h4></div></div></div><div id="Bupropion.Comment"><h4>Comment</h4><p>Bupropion is a commonly used antidepressant which is also used in therapy of smoking cessation. Liver enzyme elevations during bupropion therapy occur in less than 1% of patients and only rare instances of clinically apparent liver injury have been attributed to bupropion. In this instance, as with many case reports on bupropion, the patient had an underlying liver disease (suspected to be alcoholic liver disease), but the clinical presentation was unlikely due to alcoholism. The role of disulfiram was not discussed in the case report, but it is a well known cause of acute liver injury and its role in this case of an acute “mixed” hepatitis cannot be excluded.</p></div></div></div><div id="Bupropion.PRODUCT_INFORMATION"><h2 id="_Bupropion_PRODUCT_INFORMATION_">PRODUCT INFORMATION</h2><div id="Bupropion.BPI" class="box boxed-text-box whole_rhythm hide-overflow"><p>
