Recent developments in the psychopharmacology of social phobia.

The past 2 decades have witnessed an upsurge in the interest in anxiety disorders. Much research effort has been dedicated to panic disorder and obsessive-compulsive disorder. However, it is only very recently that we have begun to understand some of the basic principles about the psychopharmacology of social phobia. Drug classes thus far studied include beta-blockers, nonselective and irreversible monoamine oxidase inhibitors (MAOIs), and benzodiazepines. Beta blockers appear to be of use in specific social phobias, such as public speaking, whereas they are of little use in generalized social phobia. There is considerable evidence suggesting that MAOIs are effective in reducing both social anxiety as well as social avoidance in generalized social phobia. A disadvantage of the conventional irreversible MAOIs is their risk for hypertensive crises when combined with dietary tyramine. Thus far only a small number of studies with selective MAO-A inhibitors, such as moclobemide and brofaromine, have been conducted in social phobia, and the results indicate that both compounds are effective. Drugs exerting selective and specific actions on certain components of, for example, the serotonergic system, can now be studied, and it is hoped that the role of 5-hydroxytryptamine) and other neuronal systems in social phobia can be elucidated. In order to gain more information about selective serotonergic drugs, the first double-blind placebo-controlled study with fluvoxamine was recently published. Preliminary results indicate a reduction in social anxiety after a prolonged treatment period. Finally, the role of peptides in the treatment of social phobia is critically reviewed. The MSH/ACTH analog Org 2766 was investigated in patients suffering from social phobia.(ABSTRACT TRUNCATED AT 250 WORDS)
