High-potency benzodiazepines (e.g., clonazepam and lorazepam) are common alternatives to or in combination with antipsychotics for acute mania, agitation, anxiety, panic, and insomnia or in those who cannot take mood stabilizers. Lorazepam IM may be used for acute agitation. A relative contraindication for long-term benzodiazepines is a history of drug or alcohol abuse or dependency.

Drug treatments for PTSD (Fig. 9—8) have until recently focused upon treating the associated comorbidities, especially depression. Because of the high degree of concomitant drug and alcohol abuse, benzodiazepines are usually best avoided. 

Chronic alcohol abuse is an expression of true dependence. Thus, therapy of this addiction is dif cult and frequently without success. There is no pharmacotherapeutic silver bullet (the NMDA receptor antagonist acamprosate may be worth trying). Above all, psychotherapeutic care, a change in milieu, and supportive treatment with benzodiazepines are important. 

An additional psychotropic medication that may be worth considering specifically for GAD is buspirone. One major benefit of buspirone can be found in the virtual absence of dependence and abuse liability. Although it is not effective for the acute relief of anxiety or panic disorders (anxiolytic effects may take up to a week to be established), buspirone may be indicated for patients with a history of alcohol abuse or among those who fear physiologic and psychological dependence with benzodiazepines. 

Abuse of the other benzodiazepines is typified by bromazepam abuse, which is in third place in the abuse statistics. It is consumed in similarly increasing amounts by all patient groups (drug, medicament, and alcohol abusers). Although a few individual dose rates reach 100 mg, most users do not attract attention or are detected too late because of low dose rates. Drug users also combine the substance with other benzodiazepines.

Benzodiazepines and other anxiolytics. Although benzodiazepines are widely used in the treatment of acute alcohol withdrawal, most nonmedical personnel involved in the treatment of alcoholism are opposed to the use of medications that can induce any variety of dependence to treat the anxiety, depression, and sleep disturbances that can persist for months following withdrawal. Researchers have debated the pros and cons of the use of benzodiazepines for the management of anxiety or insomnia in alcoholic patients and other substance abuse patients during the postwithdrawal period (Ciraulo and Nace 2000 Posternak and Mueller 2001). 

The benzodiazepines currently available for clinical use vary substantially in pharmacokinetics, acute euphoriant effects, and frequency of reported dependence. It is likely, therefore, than not all benzodiazepines have the same potential for abuse. Diazepam, lorazepam, and alprazolam may have greater abuse potential than chlordiazepoxide and clorazepate (Wolf et al. 1990). Similarly, oxazepam has been reported to produce low levels of abuse (Eliding 1978). Jaffe et al. (1983) found that in recently detoxified alcoholic patients, halazepam produces minimal euphoria even at a supratherapeutic dosage. The development of partial agonist and mixed agonist/antagonist compounds at the benzodiazepine receptor complex may offer an advantage over approved benzodiazepines for use in alcoholic patients.

There is some evidence of a synergistic effect on reinforcement with concurrent administration of benzodiazepines and opioids (Walker and Ettenberg 2003). Cocaine abusers are less likely than opioid abusers to abuse benzodiazepines, preferring alcohol and opioids as secondary drugs of abuse. The most common pattern of benzodiazepine misuse in these individuals is intermittent use of therapeutic or supratherapeutic doses to counter unwanted effects of cocaine. 

Although estimates vary widely, approximately 10%-20% of individuals presenting for treatment of alcohol dependence may be using or abusing benzodiazepines (Ciraulo et al. 1988b Ciraulo et al. 2004 Johansson et al. 2003 ... 

Lejoyeux et al. 1998). Similar to opioid-dependent persons, these patients reported that they use benzodiazepines to self-medicate anxiety, insomnia, and alcohol withdrawal and, less commonly, to enhance the effects of ethanol. Approximately l6%-25% of patients presenting for treatment of anxiety disorders abuse alcohol (Kushner et al. 1990 Otto et al. 1992). Controversy exists concerning appropriate benzodiazepine prescribing in this population (Cir-aulo and Nace 2000 Posternak and Mueller 2001). 

Benzodiazepines have a low risk for abuse in anxiety disorder patients without a history of alcohol or other substance abuse. Among the benzodiazepines there may be a spectrum of abuse liability, with drugs that serve as prodrugs for desmethyldiazepam (e.g., clorazepate), slow-onset agents (e.g., oxazepam), and partial agonists (e.g., abecarnil) having the least potential for abuse. However, there is no currently marketed benzodiazepine or related drug that is free of potential for abuse.
