Psychopharmacological Treatments 591tine dependence is 75–100 mg daily, but it should be us<strong>ed</strong> with caution in thosewith cardiovascular disease given its possible effects on cardiac function. Likebupropion, nortriptyline is an antidepressant and may be useful in the treatment<strong>of</strong> depress<strong>ed</strong> cigarette smokers. Another antidepressant relat<strong>ed</strong> m<strong>ed</strong>ication,selegiline, an MAO inhibitor, has shown some recent efficacy in r<strong>ed</strong>ucingsmoking (George et al., 2003).Finally, clonidine, a noradrenergic alpha 2agonist that decreases centralsympathetic activity, may be an effective treatment for those who do not wantnicotine replacement therapy or who have fail<strong>ed</strong> other smoking cessationmethods.ALCOHOL PHARMACOTHERAPIESAcute Withdrawal M<strong>ed</strong>icationsAcute withdrawal from alcohol is a serious m<strong>ed</strong>ical condition that can precipitateadrenergic activation, seizures, or delirium tremens, a condition with up to15% mortality when untreat<strong>ed</strong> (Kosten & O’Connor, 2003). The current standardapproach to alcohol detoxification uses tapering dosages <strong>of</strong> benzodiazepines,such as chlordiazepoxide or clonazepam, which are effective in relievingthe autonomic hyperactivity <strong>of</strong> withdrawal and will prevent seizures. Benzodiazepinesare initially made available on an as-ne<strong>ed</strong><strong>ed</strong> basis, with parameters fordosing bas<strong>ed</strong> on appearance <strong>of</strong> withdrawal symptoms including agitation,diaphoresis, tremor, hypertension, and tachycardia. Withdrawal symptoms canbe assess<strong>ed</strong> over the course <strong>of</strong> the detoxification using the <strong>Clinical</strong> InstituteWithdrawal Assessment <strong>of</strong> Alcohol Scale, revis<strong>ed</strong> (CIWA-Ar; Sullivan,Sykora, Schneiderman, Naranjo, & Sellers, 1989). This extensively studi<strong>ed</strong>scale has been shown to have good reliability, reproducibility, and validity. Thescale measures 10 symptoms associat<strong>ed</strong> with withdrawal, each <strong>of</strong> which can bescor<strong>ed</strong> in increasing severity on a scale <strong>of</strong> 0–7 (with the exception <strong>of</strong> orientationand clouding <strong>of</strong> sensorium, which are scor<strong>ed</strong> on a scale <strong>of</strong> 0–4. Scoresabove 10 indicate a ne<strong>ed</strong> for m<strong>ed</strong>ication to treat withdrawal symptoms. Furthermore,the CIWA pr<strong>ed</strong>icts that those with a score <strong>of</strong> greater than 15 are atincreas<strong>ed</strong> risk for severe alcohol withdrawal, with higher scores conveyinghigher risk. Although detoxification sch<strong>ed</strong>ules must be individualiz<strong>ed</strong>, a benzodiazepinetaper can usually be accomplish<strong>ed</strong> in 3–4 days. Patients with hepaticdisease should be detoxifi<strong>ed</strong> with lorazepam or oxazepam, shorter-acting drugsthat, unlike the other benzodiazepines, have no active metabolites requiringhepatic clearance. Lorazepam is also a good choice for detoxification <strong>of</strong> thepatient with severe vomiting, because it is well absorb<strong>ed</strong> by the intramuscularroute <strong>of</strong> administration.Anticonvulsants have been shown to be equal in effectiveness to benzodiazepinesin the treatment <strong>of</strong> alcohol withdrawal (Malcolm, Myrick, Brady, &Ballenger, 2001). Multiple studies support the efficacy <strong>of</strong> sodium valproate
