fluvoxamine and Somatoform-Disorders

The mainstay of the pharmacologic treatment of obsessive-compulsive disorder (OCD) is a 10- to 12-week trial of a potent serotonin reuptake inhibitor (SRI) at an adequate dose. Double-blind, placebo-controlled trials have established the anti-obsessive-compulsive (OC) efficacy of five different SRIs. One of the most thoroughly studied of these SRIs is fluvoxamine, the focus of this article. Fluvoxamine's pharmacologic and pharmacokinetic properties, its efficacy, and guidelines for its clinical use in OCD and related disorders are briefly reviewed. Potential drug-drug interactions are discussed and placed in clinical perspective. The management of common SRI-induced side effects is also addressed. Recent comparative studies suggest that fluvoxamine may be equivalent in efficacy to clomipramine, yet better tolerated. Fluvoxamine shows promise in the treatment of several so-called OC-spectrum disorders, but additional controlled trials are needed.

A prospective, open-label clinical trial was conducted for two aims: first, to evaluate the role of fluvoxamine, one of selective serotonin reuptake inhibitors, in the treatment of dizziness for the first time and to investigate its effective mechanisms. Second, to test the hypothesis that dizziness in patients without abnormal neuro-otologic findings would be induced by psychiatric disorders rather than by unnoticed neuro-otologic diseases. Nineteen patients with neuro-otologic diseases (Group I) and 22 patients in whom standard vestibular tests revealed no abnormal findings (Group II) were treated by fluvoxamine (200 mg/day) for eight weeks. Subjective handicaps due to dizziness using a questionnaire, anxiety and depressive symptoms measured with the Hospital Anxiety and Depression Scale (HADS), and stress hormones (vasopressin and cortisol) were examined before and 8 weeks after treatment. Overall, fluvoxamine decreased subjective handicaps of both Groups I and II. Fluvoxamine decreased HADS of only patients whose subjective handicaps were reduced (=responders) in both groups, suggesting that fluvoxamine was effective for dizziness via psychiatric action rather than a recovery of vestibular function through serotonergic activation. In non-responders of Group II, pre-treatment HADS was higher than in Group I non-responders and it was not decreased by the treatment, suggesting that dizziness of Group II non-responders was due to severe psychiatric disorders rather than unnoticed neuro-otologic diseases. Anxiety and depression components of HADS showed a good correlation at both pre- and post-treatment periods. No post-therapeutic decrease was observed in either vasopressin or cortisol even in responders, suggesting that dizziness was not the sole cause of stress in chronic dizziness patients. In conclusion, patients with or without physical neuro-otologic deficits who report chronic dizziness accompanied by anxiety and depression (as measured by HADS) showed improvements across a full range of subjective handicaps and psychological distress, while patients with physical neuro-otologic defects and minimal anxiety or depression did not benefit. The main causes of dizziness in patients without physical neuro-otologic findings were psychiatric disorders.

To evaluate the prevalence of somatic symptoms (SSs) in children and adolescents with anxiety disorders; the relationship between SSs and anxiety severity, impairment, and child global functioning; and the impact of fluvoxamine (FLV) versus pill placebo (PBO) on reducing SSs.. As part of a double-blind, placebo-controlled trial, 128 children (mean age, 10.8 years; range, 6-17) with DSM-IV anxiety disorders (i.e., social, separation, and generalized anxiety) were assessed by expert clinicians on 16 SSs using the Pediatric Anxiety Rating Scale.. The most common SSs at baseline were restlessness (74%), stomachaches (70%), blushing (51%), palpitations (48%), muscle tension (45%), sweating (45%), and trembling/shaking (43%). Older children (age 12 and older) reported more SSs than younger children, boys and girls reported similar numbers of SSs, and SSs were higher among children with than without generalized anxiety disorder. SSs were significantly and positively correlated with anxiety severity, impairment, and global functioning. Pre-/postreductions in SSs were statistically significant in both PBO and FLV conditions; however, FLV was superior to PBO in reducing SSs.. SSs are highly prevalent among children and adolescents with anxiety disorders and are associated with greater anxiety severity and impairment. Treatment with FLV was effective in reducing rather than increasing SSs. The high rates of SSs in youths with each of the three anxiety disorders suggest a re-evaluation of SSs in the DSM-IV diagnostic criteria for the most common anxiety disorders among children and adolescents.

Body dysmorphic disorder (BDD) is a relatively common and impairing disorder. However, little is known about non-BDD symptoms and well-being in patients with this disorder. Seventy-five outpatients with DSM-IV BDD completed the Symptom Questionnaire, a validated self-report measure with four scales: depression, anxiety, somatic/somatization, and anger-hostility. Scores were compared to published norms for normal subjects and psychiatric outpatients. Participants in an open-label fluvoxamine trial completed the Symptom Questionnaire at baseline and endpoint. Compared to normal controls, BDD subjects had markedly elevated scores on all four scales, indicating severe distress and psychopathology. Compared to psychiatric patients, BDD subjects had higher scores on the depression, anxiety, and anger/hostility scales but not on the somatic/somatization scale. Scores on all scales significantly decreased with fluvoxamine. In conclusion, patients with BDD have markedly high levels of distress, are highly symptomatic, and have poor well-being in the domains of depression, anxiety, somatic symptoms, and anger-hostility. All of these symptoms significantly improved with fluvoxamine.

Prostatodynia is a common and often disabling condition that affects males and has the characteristics of a somatoform pain disorder. It presents with urogenital pain and urinary symptoms. Failure of conventional treatment and a successful uncontrolled pilot study with fluvoxamine in this condition prompted this study.. In a randomized double-blind trial, 42 patients with prostatodynia were assigned to receive either fluvoxamine (N = 21) or placebo (N = 21) for up to 8 weeks. Doses were adjusted according to therapeutic need. The median dose of fluvoxamine was 150 mg (range, 50-300 mg). Self-rated pain scores, urinary flow rates, and depression and anxiety scores were measured at baseline and several times throughout the study period.. The groups were similar at baseline, and the results were examined by intent-to-treat analysis either using the last observation carried forward or, in the case of dichotomous measures, counting treatment dropouts as treatment failures. Fluvoxamine was significantly more likely to reduce pain intensity (p = .01) and normalize urinary flow rates (p = .03) with a clinically significant number needed to treat value of 1.5 (confidence interval = 1.12 to 5.50). This therapeutic effect could not be attributed to change in mood, as the 2 groups did not differ with respect to affective ratings at the end of the study. The fluvoxamine-treated group had significantly lower (p = .02) final scores on the General Health Questionnaire, indicating an overall benefit from pain relief.. Fluvoxamine is a viable treatment for prostatodynia. Dose-ranging studies and longer trials are needed to evaluate this agent further.

Available data suggest that the delusional variant of body dysmorphic disorder (BDD), a type of delusional disorder, may respond to serotonin reuptake inhibitors (SRIs) and that delusionality (lack of insight) in BDD may improve with SRI treatment. However, this research has been hampered by the lack of a reliable and valid scale to assess delusionality.. Thirty subjects (21 women, 9 men; mean age = 33.3 +/- 9.0 years) with DSM-IV BDD were prospectively treated with open-label fluvoxamine for 16 weeks. Subjects were assessed at regular intervals with the Brown Assessment of Beliefs Scale (BABS), the Yale-Brown Obsessive Compulsive Scale Modified for BDD (BDD-YBOCS; a measure of BDD severity), and other instruments. The BABS is a reliable and valid 7-item, semistructured, clinician-administered scale that assesses current delusionality.. In this prospective, open-label study, 63% of BDD subjects responded to fluvoxamine. Delusional and nondelusional subjects had similar improvement in BDD symptoms. In addition, insight significantly improved in both delusional and nondelusional subjects. Baseline BABS scores did not contribute significantly to endpoint BDD-YBOCS scores in a regression analysis.. Degree of delusionality did not predict fluvoxamine response, and delusionality significantly improved. These findings are preliminary and require confirmation in controlled trials. The implications of these findings for other types of delusions requires investigation.

Body dysmorphic disorder (BDD), a preoccupation with an imagined or slight defect in appearance, has been noted in case reports, retrospective studies, and clinical series to respond to serotonin reuptake inhibitors (SRIs). These data further suggest that the delusional variant of BDD (delusional disorder, somatic type) may also respond to SRIs. However, systematic pharmacologic treatment studies of BDD and its delusional variant are needed.. Thirty subjects with BDD or its delusional variant (DSM-IV) were prospectively treated in an open-label fashion with fluvoxamine for 16 weeks. Subjects were assessed at regular intervals with the Yale-Brown Obsessive Compulsive Scale Modified for BDD (BDD-YBOCS), the Clinical Global Impressions (CGI) scale, the Hamilton Rating Scale for Depression, the Brown Assessment of Beliefs Scale, and other measures.. BDD-YBOCS scores (mean +/- SD) decreased from 31.1 +/- 5.4 at baseline to 16.9 +/- 11.8 at termination (p < .001). Nineteen (63.3%) subjects were rated as responders on the BDD-YBOCS and the CGI (10 [33.3%] were much improved, and 9 [30.0%] were very much improved). Delusional subjects were as likely to respond to fluvoxamine as nondelusional subjects, and delusionality significantly improved. All 5 responders who were delusional at baseline were no longer delusional at study endpoint. The mean dose of fluvoxamine was 238.3 +/- 85.8 mg/day, and mean time to response was 6.1 +/- 3.7 weeks. Fluvoxamine was generally well tolerated.. These results suggest that fluvoxamine is a safe and effective treatment for BDD, including its delusional disorder variant. Controlled treatment trials are needed to confirm these findings.

Although the pharmacologic treatment of somatoform disorders has scarcely been investigated, there is reason to believe that antidepressants might be useful. We examined the response of 29 patients with somatoform disorders from a general medicine clinic to a selective serotonin reuptake inhibitor, fluvoxamine. The drug was administered in doses of up to 300 mg daily for 8 weeks. Sixty-one percent of the patients who took medication for at least 2 weeks were at least moderately improved. In addition to antidepressant effects, fluvoxamine had other beneficial effects and was well-tolerated. The benefits of drug therapy were modest but appear to warrant a placebo-controlled trial.

Fifteen consecutive patients with a DSM-III-R diagnosis of body dysmorphic disorder (BDD) were included in a 10-week open clinical trial of fluvoxamine. Treatment began at 100 mg/day fluvoxamine and was increased to a maximum of 300 mg/day or until intolerable side effects developed or a complete or nearly complete resolution of symptoms occurred. At baseline and at weeks 2, 6 and 10, patients completed the Hopkins Symptoms Check-List (HSCL-90) and a specific rating scale for BDD symptoms (BDDSS), and clinicians completed a Clinical Global Improvement Scale. Twelve of the 15 patients completed the trial. Of the three patients who did not complete the study, one improved moderately during the placebo phase, one showed a marked worsening of the depressive symptoms during the wash-out phase and one showed adverse side effects, such as nausea and diarrhoea, after the first week of treatment and was unable to continue the trial. After 10 weeks, of the 12 remaining patients, 10 were considered to be markedly improved, one minimally improved and one unchanged. Several outcome measures showed a significant improvement from baseline to week 10. Our findings suggest that fluvoxamine may be effective in the treatment of BDD. Double-blind studies will be required to investigate these findings further.

Body dysmorphic disorder (BDD), a preoccupation with an imagined or slight defect in appearance, has been described for more than a century and reported around the world. However, this distressing and impairing disorder often goes undiagnosed, even though available data suggest that it is relatively common. Virtually any body part can be the focus of concern, with preoccupations most often involving the hair, nose, or skin. Most patients engage in excessive and repetitive behaviors such as mirror checking, skin picking, and reassurance seeking. Insight is generally poor, and many patients are frankly delusional. Most patients experience significant impairment in functioning, and suicide attempts are relatively common. Although the majority of patients with BDD seek often costly nonpsychiatric treatment-most often, surgical or dermatologic-such treatment usually appears to be unsuccessful. In contrast, preliminary data from open studies suggest that the serotonin reuptake inhibitors are often, and perhaps preferentially, effective for BDD. Augmentation, combination, and switching strategies may be useful in treatment-resistant cases. Preliminary data suggest that cognitive-behavioral strategies using exposure and response prevention may also be effective. Investigation of all aspects of this understudied disorder, including controlled treatment trials, is greatly needed.
