    BACKGROUND & AIMS: The effect of citalopram and placebo in the treatment of alcoholism was studied in a sample of 62 patients with a follow-up period of four months. The results imply that the new 5-HT re-uptake inhibitor citalopram is significantly more effective than placebo in the treatment of alcoholism. The present study indicates that even severe alcoholism may be treated effectively with a generally available psychopharmacological agent.

    背景与目标: 在62名患者的样本中研究了西酞普兰和安慰剂在酒精中毒治疗中的作用,随访期为四个月。结果表明,新的5-HT再摄取抑制剂西酞普兰在治疗酒精中毒方面比安慰剂有效。本研究表明,即使是严重的酒精中毒,也可以使用一种普遍可用的心理药物进行有效治疗。

    BACKGROUND & AIMS: :This study investigated the effect of co-administration of the selective 5-HT1A receptor antagonist WAY 100,635 and selective 5-HT(1B/1D) receptor antagonist GR 127,935 with a subactive dose of citalopram [selective serotonin (5-HT) reuptake inhibitor (SSRI)] on the expression of conditioned freezing, an index of fear. In the present study, acute administration of citalopram (s.c.) reduced freezing significantly at high doses (10, 30 and 100 mg/kg), while showing no significant effect at low doses (1 and 3 mg/kg). Co-administration of WAY 100,635 (0.15 mg/kg) with citalopram (3 mg/kg) reduced freezing markedly and significantly, as compared with either drug alone. However, the addition of GR 127,935 (4 mg/kg) did not potentiate the effects of citalopram (3 mg/kg) on freezing and did not enhance the effect of WAY 100,635 (0.15 mg/kg) with citalopram (3 mg/kg). Co-administration of WAY 100,635 (0.15 mg/kg) or GR 127,935 (4 mg/kg) gave no effect on high-dose citalopram (30 mg/kg)-induced inhibition of freezing behavior. These results suggest that co-administration of WAY 100,635 (0.15 mg/kg) strengthens the anxiolytic effect of citalopram (3 mg/kg) by facilitating central 5-HT neurotransmission. Since GR 127,935 (4 mg/kg) failed to accelerate the inhibition of freezing induced by citalopram (3 mg/kg) with WAY 100,635 (0.15 mg/kg) or citalopram (3 mg/kg) alone, it is suggested that blocking 5-HT1A receptors is more effective in facilitating the anxiolytic effect of citalopram than blocking 5-HT1B/1D receptors.
    背景与目标: : 本研究调查了选择性5-HT1A受体拮抗剂WAY 100,635和选择性5-HT(1B/1D) 受体拮抗剂GR 127,935与亚活性剂量西酞普兰 [选择性5-羟色胺 (5-HT) 再摄取抑制剂 (SSRI)] 共同给药对条件冷冻 (恐惧指数) 表达的影响。在本研究中,在高剂量 (10、30和100 mg/kg) 下,西酞普兰 (s.c.) 的急性给药显著降低了冷冻,而在低剂量 (1和3 mg/kg) 下没有显著效果。与单独使用任何一种药物相比,路100,635 (0.15 mg/kg) 与西酞普兰 (3 mg/kg) 的共同给药显着降低了冷冻。然而,添加GR 127,935 (4 mg/kg) 不能增强西酞普兰 (3 mg/kg) 对冷冻的作用,也不能增强西酞普兰 (3 mg/kg) 对WAY 100,635 (0.15 mg/kg) 的作用。100,635 (0.15 mg/kg) 或GR 127,935 (4 mg/kg) 的共同给药对大剂量西酞普兰 (30 mg/kg) 诱导的冷冻行为抑制没有影响。这些结果表明,联合给予WAY 100,635 (0.15 mg/kg) 通过促进中枢5-HT神经传递来增强西酞普兰 (3 mg/kg) 的抗焦虑作用。由于GR 127,935 (4 mg/kg) 未能加速西酞普兰 (3 mg/kg) 与WAY 100,635 (0.15 mg/kg) 或西酞普兰 (3 mg/kg) 单独诱导的冷冻抑制,建议阻断5-HT1A受体比阻断5-HT1B/1D受体更有效地促进西酞普兰的抗焦虑作用。

    BACKGROUND & AIMS: :The serotonin syndrome is caused by a drug-induced increase of the intrasynaptic serotonin concentration. Milder forms of the syndrome may be difficult to diagnose because of the variability of symptoms. Severe forms often rapidly turn into a life-threatening situation, therefore the serotonin syndrome may be a challenge for physicians. We describe the pathophysiology and therapeutic options of the serotonin syndrome and report about a 42-year-old female patient who ingested large amounts of moclobemide, a monoamine oxidase inhibitor, and citalopram, a selective serotonin reuptake inhibitor, for attempted suicide. Within a few hours the patient developed a lethal serotonin syndrome although ICU therapy was initiated immediately.

    BACKGROUND & AIMS: INTRODUCTION:Selective serotonin reuptake inhibitors (SSRIs) are frequently used in the treatment of irritable bowel syndrome (IBS) although evidence of their efficacy is scarce. AIM:Twenty three non-depressed IBS patients were recruited from a tertiary care centre and included in a crossover trial comparing six weeks of treatment with the SSRI citalopram (20 mg for three weeks, 40 mg for three weeks) with placebo. IBS symptom severity was the primary outcome measure, and depression and anxiety scores were also measured. The effect of acute administration of citalopram on colonic sensitivity and on colonic response to feeding was investigated as a putative predictor of symptomatic response to the drug. RESULTS:After three and six weeks of treatment, citalopram significantly improved abdominal pain, bloating, impact of symptoms on daily life, and overall well being compared with placebo. There was only a modest effect on stool pattern. Changes in depression or anxiety scores were not related to symptom improvement. The effect of acute administration of citalopram during a colonic barostat study did not predict clinical outcome. Analysis of the first treatment period as a double blind parallel arm study confirmed the benefit of citalopram over placebo. CONCLUSIONS:The SSRI citalopram significantly improves IBS symptoms, including abdominal pain, compared with placebo. The therapeutic effect is independent of effects on anxiety, depression, and colonic sensorimotor function.

    BACKGROUND & AIMS: :We investigated the somatic maturation of neonate rats treated during the suckling period with citalopram, a selective serotonin reuptake inhibitor. Groups with 6 male neonates were randomly assigned to different treatments 24 h after birth. Each litter was suckled by one of the dams until the 21st postnatal day. Body weight, head axis and tail length were measured daily from the 1st to the 21st postnatal day. Time of ear unfolding, auditory conduit opening, incisor eruption, and eye opening was determined. Pups received 5 mg (Cit5), 10 mg (Cit10) or 20 mg/kg (Cit20) citalopram sc, or saline (0.9% NaCl, w/v, sc). Compared to saline, body weight was lower (24.04%, P < 0.01) for Cit10 from the 10th to the 21st day and for Cit20 from the 6th to the 21st day (38.19%, P < 0.01). Tail length was reduced in the Cit20 group (15.48%, P < 0.001) from the 8th to the 21st day. A reduction in mediolateral head axis (10.53%, P < 0.05) was observed from the 11th to the 21st day in Cit10 and from the 6th to the 21st day in Cit20 (13.16%, P < 0.001). A reduction in anteroposterior head axis was also observed in the Cit20 group (5.28%, P < 0.05) from the 13th to the 21st day. Conversely, this axis showed accelerated growth from the 12th to the 21st day in the Cit5 group (13.05%, P < 0.05). Auditory conduit opening was delayed in the Cit5 and Cit20 groups and incisor eruption was delayed in all citalopram groups. These findings show that citalopram injected during suckling to rats induces body alterations and suggest that the activity of the serotoninergic system participates in growth mechanisms.

    BACKGROUND & AIMS: :Citalopram, an antidepressant whose use has become more widespread in Spain in recent years participates directly and indirectly in the lethal mechanism in voluntary and involuntary poisonings. There were 30 cases of autopsies in the Madrid region where citalopram and other psychoactive substances (psychotropic drugs, alcohol, opiates) were detected in the corpses. The postmortem citalopram levels in relation to the manner and mechanism of death were evaluated, and a significant difference between the toxic and nontoxic cases (p < 0.01) was found. We studied the citalopram blood levels alone and along with other psychoactive products, and these cases were then further divided into those where the compounds were at deadly levels and those which were not. We found a range of citalopram levels between 0.37 and 0.83 microg/mL in which some cases were associated with citalopram toxicity and others were not. Citalopram blood levels of less than 0.35 microg/mL did not lead to fatal poisoning when it was the sole substance detected.
    背景与目标: 西酞普兰,一种抗抑郁药,近年来在西班牙的使用越来越广泛,直接和间接参与自愿和非自愿中毒的致死机制。马德里地区有30例尸体解剖,在尸体中检测到西酞普兰和其他精神活性物质 (精神药物,酒精,鸦片)。评估了死后西酞普兰水平与死亡方式和死亡机制的关系,发现毒性和无毒性病例之间存在显着差异 (p <0.01)。我们单独研究了西酞普兰的血液水平以及其他精神活性产品,然后将这些病例进一步分为化合物处于致命水平的病例和不处于致命水平的病例。我们发现西酞普兰水平范围在0.37至0.83微克/毫升之间,其中一些病例与西酞普兰毒性有关,而另一些病例与西酞普兰毒性无关。当西酞普兰是检测到的唯一物质时,低于0.35微克/毫升的血液水平不会导致致命中毒。

    BACKGROUND & AIMS: OBJECTIVE:The objective of this study was to explore the efficacy of combination therapy with citalopram plus omega-3 fatty acids versus citalopram plus placebo (olive oil) in the initial treatment of individuals with major depressive disorder (MDD). We hypothesized that combination therapy would lead not only to greater efficacy but also to a more rapid onset of therapeutic response. METHODS:Forty-two subjects participated in this 9-week randomized, masked, placebo-controlled study of combination therapy (two 1 g capsules containing a blend of 900 mg of eicosapentaenoic acid, 200 mg of and docosahexaenoic acid, and 100 mg of other omega-3 fatty acids twice daily plus citalopram) versus monotherapy (two 1 g capsules of olive oil per day plus citalopram) treatment of MDD. RESULTS:The combination therapy demonstrated significantly greater improvement in Hamilton Depression Rating scale scores over time (F = 7.32; df 1,177; P = 0.008) beginning at week 4 (t = -2.48; df 177; P = 0.014). CONCLUSIONS:Combination therapy was more effective than monotherapy in decreasing signs and symptoms of MDD during the 8 weeks of active treatment; however, combination therapy did not seem to enhance the speed of the initial antidepressant response. These findings suggest that there may be an advantage to combining omega-3 fatty acids with a selective serotonin uptake inhibitor in the initial treatment of individuals with MDD. A larger definitive study is warranted.

    BACKGROUND & AIMS: OBJECTIVE:To compare within the framework of a novel pharmacopsychometric triangle, augmentation treatment with bupropion vs. buspirone in the acute therapy of major depression in the STAR*D study. The triangle provides a composite view in three domains of antidepressive activity, side effects, and quality of life. METHOD:Within the pharmacopsychometric triangle, the short six-item subscales of the Hamilton Depression Scale (HAM-D(17)) and of the Inventory of Depressive Symptomatology (IDS-C(30)), referred to as HAM-D(6) and IDS-C(6), were focussed on pure antidepressive effect. Side-effects (tolerable vs. intolerable) and quality of life were measured using patient-administered questionnaires. A modified intention to treat sample was used. RESULTS:Within the pharmacopsychometric triangle, bupropion-SR (sustained release) was superior to buspirone when augmented to the current citalopram treatment. Thus, in the domain of pure antidepressive effect, bupropion-SR was superior (P = 0.05) on the HAM-D(6), IDS-C(6), and IDS-C(30), but not on the HAM-D(17). In the domain of side effects, the total scores on the Patient Rated Inventory of Side Effects (PRISE) were reduced significantly more by bupropion-SR than by buspirone (P = 0.03). In the domain of quality of life, the total scores on the Quality of Life Enjoyment and Satisfaction Questionnaire (QLES-Q) showed a trend (P = 0.10) from baseline to endpoint of a superiority for bupropion-SR compared with buspirone. CONCLUSION:In all domains of the pharmacopsychometric triangle, bupropion-SR was superior to buspirone as augmentation therapy in depressed outpatients not responding to citalopram.

    BACKGROUND & AIMS: OBJECTIVE:Obsessive-compulsive disorder (OCD) is one of the chronic anxiety disorders that interfere with routine individual life, occupational and social functions. There is controversy about the first choice of treatment for OCD between medication and psychotherapy. AIM:the aim was to investigate the efficacy of eye movement desensitization and reprocessing (EMDR) compared with medication by citalopram in treatment of OCD. METHODS:This randomized controlled trial was carried out on 90 OCD patients that randomly were assigned into two groups. They either received therapeutic sessions of EMDR or citalopram during 12 weeks. Both groups blindly were evaluated by the Yale-Brown scale before and after the trial period. RESULTS:Pretreatment average Yale-Brown score of citalopram group was about 25.26 as well as 24.83 in EMDR group. The after treatment scores were 19.06 and 13.6, respectively. There was significant difference between the mean Yale-Brown scores of the two groups after treatment and EMDR was more effective than citalopram in improvement of OCD signs. CONCLUSION:It is concluded that although both therapeutic methods (EMDR and Citalopram) had significant effect in improving obsessive signs but it seems that in short term EMRD has better effect in improvement of final outcome of OCD.

    BACKGROUND & AIMS: BACKGROUND:Administration of 5-hydroxytryptamine (5HT) and selective 5HT receptor ligands modifies interdigestive motility in animals and in man. AIM:To study the effect of citalopram, a selective 5-HT reuptake inhibitor, on interdigestive motility in man. METHODS:In 20 healthy subjects, antroduodenojejunal motor activity was studied manometrically. Basal interdigestive motor activity was recorded until the passage of two activity fronts. Ten minutes after the second activity front, placebo or 20 mg of citalopram was administered intravenously in a double-blind randomized fashion. Recording continued until the passage of two more activity fronts had occurred. RESULTS:Administration of citalopram induced a premature small intestinal phase 3 after 35 +/- 6.4 min, compared to 120 +/- 17 min after placebo P < 0.01. Citalopram shortened MMC cycle length at the expense of phase 1 and phase 2 and significantly increased the motility index during phase 2 in the antrum and the small intestine. CONCLUSIONS:In the interdigestive state in man, intravenous administration of the selective 5-HT reuptake inhibitor citalopram induces a premature intestinal phase 3 and suppresses gastric activity fronts. Phase 2 motility is stimulated both in the stomach and in the small bowel after citalopram. These data suggest that 5HT is involved in the control of interdigestive motility.

    BACKGROUND & AIMS: BACKGROUND:Hyponatremia secondary to the syndrome of inappropriate secretion of antidiuretic hormone is an uncommon complication of treatment with the new class of antidepressant agents, the selective serotonin reuptake inhibitors. The risk of hyponatremia seems to be highest during the first weeks of treatment particularly, in elderly females and in patients with a lower body weight. CASE PRESENTATION:A 61-year-old diabetic male was admitted to the hospital because of malaise, progressive confusion, and a tonic/clonic seizure two weeks after starting citalopram, 20 mg/day. On physical examination the patient was euvolemic and had no evidence of malignancy, cardiac, renal, hepatic, adrenal or thyroid disease. Laboratory tests results revealed hyponatremia, serum hypoosmolality, urine hyperosmolarity, and an elevated urine sodium concentration, leading to the diagnosis of inappropriate secretion of antidiuretic hormone. Citalopram was discontinued and fluid restriction was instituted. The patient was discharged after serum sodium increased from 124 mmol/L to 134 mmol/L. Two weeks after discharge the patient denied any new seizures, confusion or malaise. At that time his serum sodium was 135 mmol/L. CONCLUSIONS:Because the use of serotonin reuptake inhibitors is becoming more popular among elderly depressed patients the present paper and other reported cases emphasize the need of greater awareness of the development of this serious complication and suggest that sodium serum levels should be monitored closely in elderly patients during treatment with citalopram.

    BACKGROUND & AIMS: OBJECTIVE:To report a case of serotonin syndrome associated with interaction between fentanyl and citalopram, as evidenced by medication history, clinical features and reversal following discontinuation of fentanyl. CASE SUMMARY:A 65-year-old patient chronically treated with the selective serotonin reuptake inhibitor (SSRI) citalopram developed confusion, agitation, tachycardia, tremors, myoclonic jerks and unsteady gait, consistent with serotonin syndrome, following initiation of fentanyl, and all symptoms and signs resolved following discontinuation of fentanyl. Based on the Naranjo probability scale, serotonin syndrome was a probable adverse reaction associated with co-administration of citalopram and fentanyl. DISCUSSION:Serotonin syndrome is a potentially lethal pharmacodynamic interaction between medications that increase serotonergic transmission at the synaptic junction. The development of new pharmacological agents with varied properties and actions has increased the risk of serotonin syndrome as a clinical diagnosis. SSRIs and fentanyl are commonly co-administered, especially in the setting of chronic or malignant pain, as underlying depression may contribute to the pathogenesis of pain. CONCLUSION:Healthcare professionals should be aware of the possible development of serotonin syndrome as a complication of initiation of fentanyl and other phenylpiperidine opioids in patients treated with SSRIs.

    BACKGROUND & AIMS: OBJECTIVE:The objective of this case report is to create awareness on restless legs syndrome (RLS) among clinicians working in emergency units. METHOD:We describe a case reporting important aggravation of RLS associated with citalopram, 60 mg/day, in a 48-year-old woman who was sent to the emergency unit by her general practitioner. Citalopram was replaced by bupropion, 150 mg/day, and sertraline, 50 mg/day. RESULTS:Three days later, symptoms of RLS started to diminish and, after 3 weeks, clinical symptoms had disappeared entirely. On 6-month follow-up, the patient did not manifest clinically significant RLS. Ignoring RLS could lead to a worsening of symptoms and could increase the risk for iatrogenic conditions. The prevalence of RLS in the general population is 3-9%; nevertheless, this syndrome is frequently underdiagnosed. CONCLUSION:This case report suggests that RLS could be considered as a possible "dopamine-dependent side effect" of selective serotonin reuptake inhibitors (SSRIs). Bupropion could potentially "correct" dopaminergic dysfunction in RLS, and sertraline appears to be the SSRI that provides the least risk of RLS by blocking dopamine reuptake.

    BACKGROUND & AIMS: OBJECTIVE:In a prospective, open-label pilot study in probable-Alzheimer disease (AD) outpatients, the authors investigated the efficacy of citalopram to reduce restless activity and aberrant motor behaviors. METHODS:Nineteen subjects were evaluated with Neuropsychiatric Inventory subscale and total scores. RESULTS:There was a significant decline in aberrant motor behaviors and overall behavior problems at 4, 8, and 12 weeks. CONCLUSION:This study provides initial evidence that citalopram may be effective in reducing aberrant motor behaviors in AD. However, because of the potential biases of an open-label study, these findings need to be confirmed in a larger, controlled trial.

    BACKGROUND & AIMS: :1. Regional distribution of the serotonin transport complex was studied in 12 different brain areas from human brains. The serotonin uptake complex was measured with 3H-paroxetine, and 3H-imipramine. The binding site density was highest in the nucleus of raphé, medium in the basal ganglia, and lowest in cortical areas. The specific binding measured with 3H-paroxetine and 3H-citalopram was compared with the high affinity 3H-imipramine binding determined with either 100 microM 5HT or 1 microM imipramine as non specific displacers. 3H-paroxetine and 3H-citalopram allowed a more precise determination of Bmax, and are both good ligands for the serotonin uptake site, but the determinations with 3H-imipramine were within the same range. 2. Protease digestion of brain membranes showed that the binding site measured with all three ligands disappeared with the same rate as other membrane proteins, and not faster as might be expected from the literature. 3. Left/right hemisphere distribution was measured in cortical tissue from 6 brains using 3H-paroxetine. No difference between the two hemispheres was found. In one brain from a lithium treated patient a very low binding was measured, possibly indicating that the lithium treatment had decreased the serotonin uptake mechanism.
