Tranquilizers (also called antianxiety drugs) are used to treat a variety of psychiatric disorders which go along with anxiety (anxiety disorders). Serotonin-reuptake inhibitors and the benzodiazepines are the most commonly employed drugs for the treatment of common clinical anxiety disorders. 

Psychiatric adverse effects occur frequently and may include irritability, depression, and rarely, suicidal ideation. Individuals with a history of uncontrolled psychiatric disorders must weigh the risk versus benefit of treatment, as interferon may exacerbate or worsen the psychiatric condition. Patients who develop mild to moderate symptoms may require antidepressants or anxiolytics. Those with severe symptoms including suicidal ideation should have the treatment discontinued immediately.43... 

Schizophrenia is a chronic, complex psychiatric disorder affecting approximately 1% of the population worldwide. The chronic nature of the illness, in addition to the early age of onset, results in direct and indirect health care expenditures in the U.S., which amount to approximately 30 to 64 billion dollars per year [4]. It is perhaps the most devastating of psychiatric disorders, with approximately 10% of patients committing suicide. The dopamine hypothesis of schizophrenia postulates that overactivity at dopaminergic synapses in the central nervous system (CNS), particularly the mesolimbic system, causes the psychotic symptoms (hallucinations and delusions) of schizophrenia. Roth and Meltzer [5] have provided a review of the literature and have concluded a role for serotonin as well in the pathophysiology and treatment of schizophrenia. The basic premise of their work stems from the known interaction between the serotonergic and dopaminergic systems. 

Most treatment-resistant depressed patients have received inadequate therapy. Issues to be considered in patients who have not responded to treatment include the following (1) Is the diagnosis correct (2) Does the patient have a psychotic depression (3) Has the patient received an adequate dose and duration of treatment (4) Do adverse effects preclude adequate dosing (5) Has the patient been compliant with the prescribed regimen (6) Was treatment outcome measured adequately (7) Is there a coexisting or preexisting medical or psychiatric disorder (8) Was a stepwise approach to treatment used (9) Are there other factors that interfere with treatment ... 

For years, psychiatric and drug abuse disorders were not even treated together. Now we know they commonly co-occur, which means for many years clients were getting only partial treatment. Even today we are still not sure how to treat these co-occurring conditions simultaneously in a consistently effective way with both psychotherapy and pharmacotherapy (see Chapter 5). The next century is likely to see many advances in both pharmacotherapy and psychotherapy to treat co-occurring conditions. There are effective methods to treat drug abuse and to treat other co-occurring psychiatric disorders. The next frontier in research is to learn how to combine these approaches in a way that can treat multiple disorders at once ... 

Shock Therapy. The early 20th century saw the development of the first effective biological treatments for depression, the shock therapies. The first shock treatments used injection of horse serum or insulin. A major advance in treatment occurred with the advent of electroconvulsive therapy (ECT) in 1934. Although initially used to treat schizophrenia, ECT was soon found to be highly effective for other psychiatric disorders including depression and mania. ECT remained the primary biological psychiatric treatment until the widespread release of psychiatric medications in the 1950s. 

Psychiatric medications do not currently play a prominent role in the treatment of cocaine-dependent patients (see Table 6.4). Although researchers have labored to find medications to treat cocaine addiction, there have not been any notable breakthroughs. As with other substance use disorders, the presence of a psychiatric disorder for which medication is indicated (i.e., depression, anxiety disorders, bipolar affective disorder, or schizophrenia) should prompt appropriate treatment. Similar to the presence of alcohol intoxication, deferring a diagnosis for a day or two in a new patient with no past history is often the more prudent course. 

Appropriate management of AN also requires the early detection and treatment of any comorbid psychiatric disorders. The most common comorbid conditions associated with AN are major depressive disorder (MDD), obsessive-compulsive disorder (OCD), and substance use disorders. At the time of presentation, over 50% of AN patients also fulfill criteria for MDD however, accurate diagnosis of depression in these patients is complicated by the fact that prolonged starvation often produces a mood disturbance and neurovegetative symptoms identical to MDD. If MDD appears to be comorbid with AN at the time of presentation, there is debate as to whether it is more prudent to withhold treatment of the depression until weight restoration has been initiated. If the depression persists despite refeeding, then treatment of the depression is likely warranted.
