AH, Storer RJ, Ounjai P, Kanthawee P, Ngamwongsatit N, Kupwiwat R, Kupwiwat C, Brimson JM, Devanga Ragupathi NK, Charuluxananan S, Leelahavanichkul A, Kanjanabuch T, Higgins PG, Badavath VN, Amarasiri M, Verhasselt V, Kicic A, Chatsuwan T, Pirzada K, Jalali F, Reiersen AM, Abe S, Ishikawa H. Early treatment with fluvoxamine, bromhexine, cyproheptadine, and niclosamide to prevent clinical deterioration in patients with symptomatic COVID-19: a randomized clinical trial

Background

Repurposed drugs with host-directed antiviral and immunomodulatory properties have shown promise in the treatment of COVID-19, but few trials have studied combinations of these agents. The aim of this trial was to assess the effectiveness of affordable, widely available, repurposed drugs used in combination for treatment of COVID-19, which may be particularly relevant to low-resource countries.

Methods

We conducted an open-label, randomized, outpatient, controlled trial in Thailand from October 1, 2021, to June 21, 2022, to assess whether early treatment within 48-h of symptoms onset with combinations of fluvoxamine, bromhexine, cyproheptadine, and niclosamide, given to adults with confirmed mild SARS-CoV-2 infection, can prevent 28-day clinical deterioration compared to standard care. Participants were randomly assigned to receive treatment with fluvoxamine alone, fluvoxamine + bromhexine, fluvoxamine + cyproheptadine, niclosamide + bromhexine, or standard care. The primary outcome measured was clinical deterioration within 9, 14, or 28 days using a 6-point ordinal scale. This trial is registered with ClinicalTrials.gov (NCT05087381).

Findings

Among 1900 recruited, a total of 995 participants completed the trial. No participants had clinical deterioration by day 9, 14, or 28 days among those treated with fluvoxamine plus bromhexine (0%), fluvoxamine plus cyproheptadine (0%), or niclosamide plus bromhexine (0%). Nine participants (5.6%) in the fluvoxamine arm had clinical deterioration by day 28, requiring low-flow oxygen. In contrast, most standard care arm participants had clinical deterioration by 9, 14, and 28 days. By day 9, 32.7% (110) of patients in the standard care arm had been hospitalized without requiring supplemental oxygen but needing ongoing medical care. By day 28, this percentage increased to 37.5% (21). Additionally, 20.8% (70) of patients in the standard care arm required low-flow oxygen by day 9, and 12.5% (16) needed non-invasive or mechanical ventilation by day 28. All treated groups significantly differed from the standard care group by days 9, 14, and 28 (p < 0.0001). Also, by day 28, the three 2-drug treatments were significantly better than the fluvoxamine arm (p < 0.0001). No deaths occurred in any study group. Compared to standard care, participants treated with the combination agents had significantly decreased viral loads as early as day 3 of treatment (p < 0.0001), decreased levels of serum cytokines interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and interleukin-1 beta (IL-1β) as early as day 5 of treatment, and interleukin-8 (IL-8) by day 7 of treatment (p < 0.0001) and lower incidence of post-acute sequelae of COVID-19 (PASC) symptoms (p < 0.0001). 23 serious adverse events occurred in the standard care arm, while only 1 serious adverse event was reported in the fluvoxamine arm, and zero serious adverse events occurred in the other arms.

Interpretation

Early treatment with these combinations among outpatients diagnosed with COVID-19 was associated with lower likelihood of clinical deterioration, and with significant and rapid reduction in the viral load and serum cytokines, and with lower burden of PASC symptoms. When started very soon after symptom onset, these repurposed drugs have high potential to prevent clinical deterioration and death in vaccinated and unvaccinated COVID-19 patients.

Prevalence of Sexual Dysfunction in Women With Depression: Need for Psychosexual Health Promotion Approach

Introduction:

Depression-associated sexual dysfunction (SD) is a pervasive and ignorant problem among the general population. The antidepressant used to treat depression may further alter the sexual response cycle in one way or another. This study aims to assess the prevalence of SD in females with major depressive disorders and the effects of antidepressant therapy after 4 weeks of follow-ups.

Material and Methods:

In a prospective observational survey, 94 women diagnosed with depression and on antidepressant therapy were purposively enrolled. Female Sexual Functioning Index (FSFI) and Montgomery-Asberg Depression Rating Scale (MADRS) are administered at baseline and 4 weeks of treatment to measure sexual function and depression changes. Relevant descriptive and inferential statistics are applied to compute the results.

Results:

The mean age of the participants was 35.87 (±5.10) years. A total of 95.7% of participants showed SD at baseline assessment. There was a significant difference (31.87 vs 18.51, P < .001) in depression from baselines to 4 weeks after antidepressant therapy. Further, a significant negative correlation was reported between the MADRS scores and the scores of arousals (r = −0.396, P < .001), lubrication (r = −0.453, P < .001), orgasm (r = −0.342, P < .001), satisfaction (r = −0.407, P < .001), pain (r = −0.362, P < .001), and total domains of FSFI (r = −0.412, P < .001) after 4 weeks. Using cut-off scores of different areas, decreased sexual desire was reported in 97.9%, poor vaginal lubrication (100%), a problem with arousal (100%), reduced satisfaction (96.8%), reduced ability to achieve orgasm (100%), and pain during sexual intercourse in 100% of the participants.

Conclusions:

There is a high prevalence of SD in women with depression. There is a marked improvement in depression at the end of 4 weeks. However, sexual function status remains unchanged and indicates the need for time to improve, suggesting different study designs.

Amantadine: reappraisal of the timeless diamond-target updates and novel therapeutic potentials

The aim of the current review was to provide a new, in-depth insight into possible pharmacological targets of amantadine to pave the way to extending its therapeutic use to further indications beyond Parkinson's disease symptoms and viral infections. Considering amantadine's affinities in vitro and the expected concentration at targets at therapeutic doses in humans, the following primary targets seem to be most plausible: aromatic amino acids decarboxylase, glial-cell derived neurotrophic factor, sigma-1 receptors, phosphodiesterases, and nicotinic receptors. Further three targets could play a role to a lesser extent: NMDA receptors, 5-HT3 receptors, and potassium channels. Based on published clinical studies, traumatic brain injury, fatigue [e.g., in multiple sclerosis (MS)], and chorea in Huntington's disease should be regarded potential, encouraging indications. Preclinical investigations suggest amantadine's therapeutic potential in several further indications such as: depression, recovery after spinal cord injury, neuroprotection in MS, and cutaneous pain. Query in the database http://www.clinicaltrials.gov reveals research interest in several further indications: cancer, autism, cocaine abuse, MS, diabetes, attention deficit-hyperactivity disorder, obesity, and schizophrenia.

Add-on mirtazapine improves orgasmic functioning in patients with schizophrenia treated with first-generation antipsychotics

AIM

Sexual dysfunction, common in schizophrenia, may be further exaggerated by antipsychotics, especially those of First Generation (FGAs), and antidepressants, such as Selective Serotonin Reuptake Inhibitors (SSRs). Mirtazapine, an antidepressant characterized by its different action mechanism compared with that of the majority of other antidepressants, may improve SSRI-induced sexual dysfunction in patients with depression. It is unknown, however, whether mirtazapine improves sexual functioning in schizophrenia.

METHODS

This study randomly assigned FGA-treated patients with schizophrenia to receive either an add-on mirtazapine (n = 20) or a placebo (n = 19) for 6 weeks. Sexual functioning was prospectively measured using five relevant items from the Udvalg for Kliniske Undersogelser side-effect rating scale (UKU-SERS).

RESULTS

Orgasmic function improved with statistical significance in the mirtazapine group (p = .03), with no changes in any other sexual functions in either group.

CONCLUSION

Add-on mirtazapine appears to relieve orgasmic dysfunction in FGA-treated patients with schizophrenia.

Female Sexual Dysfunction: Review of the Disorder and Evidence for Available Treatment Alternatives

With the introduction and marketing of sildenafil, national attention has focused on sexual dysfunction in men. However, strides are being made to focus more effort on evaluation and treatment of female sexual disorder (FSD) since a 1999 national survey reported prevalence rates as high as 43% in women. Evaluation and assessment of FSD requires a comprehensive history and physical examination. Understanding of FSD requires knowledge and understanding of sexual anatomy, physiology, and pathophysiology. Nonpharmacologic treatment may include sex therapy or relationship counseling. Pharmacologic treatment of FSD has focused mainly on hormonal therapies, including estrogen and testosterone, with the majority of studies being done in postmenopausal and hysterectomized women. However, recent studies indicate a more prudent and careful use of hormonal therapies. Research is also moving toward evaluation of bupropion and sildenafil as options for women who suffer from FSD. Available evidence for treatment alternatives is scant and in some cases inconclusive.

Antidepressant-Induced Sexual Dysfunction

OBJECTIVE:

To review the evidence regarding antidepressant-induced sexual dysfunction and address implications for treatment strategy and health plan coverage policies for antidepressant medications.

DATA SOURCES:

Primary articles were identified by a MEDLINE and HealthSTAR search to identify English-language studies published between January 1986 and July 2000. Search terms included sexual dysfunction or sexual function and antidepressants, fluoxetine, sertraline, paroxetine, fluvoxamine, citalopram, venlafaxine, nefazodone, bupropion, and mirtazapine. A cross-check of references cited in 10 published reviews yielded additional in-scope articles.

STUDY SELECTION AND DATA EXTRACTION:

Approximately 200 articles were identified, including 8 randomized controlled trials and numerous open-label studies, case series, and case reports. Of the randomized controlled trials, only 5 were designed to evaluate the incidence of sexual dysfunction associated with antidepressant treatment. Three additional randomized controlled trials included a structured assessment of sexual dysfunction within an efficacy trial. Data extraction excluded case reports, letters, and other limited study designs. A panel survey augmented published reports.

DATA SYNTHESIS:

Sexual dysfunction is a relatively common adverse effect of many of the antidepressants in common use today. Rates of sexual dysfunction observed in clinical practice may be higher than those reported in the product information for several agents. Selective serotonin-reuptake inhibitors (SSRIs) appear to be the class of antidepressants most likely to cause sexual dysfunction. Published studies suggest that between 30% and 60% of SSRI-treated patients may experience some form of treatment-induced sexual dysfunction. Bupropion and nefazodone appear to be much less likely to cause sexual dysfunction (≤10% of patients). Mirtazapine also appears to be associated with a low rate of sexual adverse effects. Panel results largely reflect the consensus of the literature.

CONCLUSIONS:

Sexual dysfunction is a common adverse effect of antidepressant treatment. Physicians should monitor their patients for antidepressant-induced sexual adverse effects, as these may affect compliance with therapy and ultimate treatment success. In addition to the consequences for patient health and well-being, managed-care organizations should be concerned with sexually related adverse effects of antidepressants, insofar as additional healthcare resources may be required to treat depressed patients in whom these adverse effects arise.

Synthesis of novel analogs of cabergoline: improving cardiovascular safety by removing 5-HT2B receptor agonism

The dopamine agonist cabergoline has been used to treat prolactinomas, Parkinson's disease, Cushing's disease and sexual dysfunction. However, its clinical use was severely curtailed when it was found that patients taking cabergoline had an increased risk of developing cardiac-valve regurgitation. This potentially life-threatening condition has been associated with drugs, such as cabergoline, that are 5-HT_2B receptor agonists. We prepared analogs of cabergoline and have identified several that have limited or no agonism at the 5-HT_2B receptor.

Saffron for treatment of fluoxetine-induced sexual dysfunction in women: randomized double-blind placebo-controlled study

OBJECTIVE

Saffron (Crocus sativus L.) has shown beneficial aphrodisiac effects in some animal and human studies. The aim of the present study was to assess the safety and efficacy of saffron on selective serotonin reuptake inhibitor-induced sexual dysfunction in women.

METHODS

This was a randomized double-blind placebo-controlled study. Thirty-eight women with major depression who were stabilized on fluoxetine 40 mg/day for a minimum of 6 weeks and had experienced subjective feeling of sexual dysfunction entered the study. The patients were randomly assigned to saffron (30 mg/daily) or placebo for 4 weeks. Measurement was performed at baseline, week 2, and week 4 using the Female Sexual Function Index (FSFI). Side effects were systematically recorded.

RESULTS

Thirty-four women had at least one post-baseline measurement and completed the study. Two-factor repeated measure analysis of variance showed significant effect of time × treatment interaction [Greenhouse-Geisser's corrected: F(1.580, 50.567) = 5.366, p = 0.012] and treatment for FSFI total score [F(1, 32) = 4.243, p = 0.048]. At the end of the fourth week, patients in the saffron group had experienced significantly more improvement in total FSFI (p < 0.001), arousal (p = 0.028), lubrication (p = 0.035), and pain (p = 0.016) domains of FSFI but not in desire (p = 0.196), satisfaction (p = 0.206), and orgasm (p = 0.354) domains. Frequency of side effects was similar between the two groups.

CONCLUSIONS

It seems saffron may safely and effectively improve some of the fluoxetine-induced sexual problems including arousal, lubrication, and pain.

Safety considerations in drug treatment of depression in HIV-positive patients: an updated review

Major depressive disorder (MDD) is one of the most prevalent illnesses associated with HIV infection, and negatively affects medication adherence, disease progression and mortality in HIV disease. Co-morbid treatment of major depression in HIV disease is the optimal therapeutic approach, but discriminating MDD from normal fluctuations in mood state, personality or physiology is difficult. Definitive diagnosis of MDD is critical for drug safety and for avoiding unnecessary exposure to psychotropic medications. HIV patients respond to antidepressant treatment like the general population, and medication adverse effects and patient adherence are the best predictors of treatment outcome. This review attempts to assist the medical provider with the diagnosis and treatment of MDD in HIV patients. We outline the initial steps in screening and psychiatric referral, the antidepressants that are particularly useful in HIV-infected patients, and the adverse effects and pharmacological strategies for overcoming potential barriers to medication adherence. Potential interactions between the various classes of antidepressants and HIV/antiretroviral therapy, as well as management of HIV medication-related psychiatric adverse effects, are also discussed.

[Sexual dysfunction induced by antidepressants]

Sexual dysfunction is often concurrent with depressive disorders. Antidepressants may induce or augment sexual dysfunction as an adverse effect. About 40% of all patients treated with selective serotonin reuptake inhibitors, or other serotonergic agents, report such effects. If sexual dysfunction is not adequately dealt with it may contribute to noncompliance and thus compromise treatment. For the norepinephrine and dopamine reuptake inhibitor bupropion, the incidence of sexual adverse effects is equal to that for placebo. Additional treatment with bupropion, or switching to mirtazapin or bupropion, may be effective. Studies in men have documented positive effects of concomitant treatment with sildenafil or tadalafil.

A Role for Preoptic Glutamate in the Regulation of Male Reproductive Behavior

Although much progress has been made toward understanding the role of the medial preoptic area (MPOA) in the regulation of male reproductive behaviors, the precise mechanisms responsible for its activation during mating are largely unclear. Several studies implicate glutamate in this response. However, not until recently was there direct evidence supporting this hypothesis. Results obtained using in vivo microdialysis showed that levels of glutamate increased in the MPOA during mating, particularly with ejaculation. Levels then decreased rapidly following ejaculation, during a period of sexual quiescence. The magnitude of this decrease correlated with time spent in quiescence. Additionally, central administration of glutamate uptake inhibitors increased levels of glutamate and facilitated behavior. Glutamate activation of N-methyl-D-aspartate (NMDA) receptors in the MPOA is at least partly responsible for behavioral effects evoked by increase glutamate. This is evidenced by histological analysis of the MPOA, which shows that nearly all cells containing mating-induced Fos also contained NMDA receptors. Mating also increased phosphorylation of NMDA receptors, indicating receptor activation. Finally, bilateral microinjections of NMDA receptor antagonists inhibited copulation. This neurochemical, anatomical, and behavioral evidence points to a key role of preoptic glutamate in the regulation of sexual behavior in males. The implications of these findings are discussed.

Drug treatment of depression in HIV-positive patients : safety considerations

Safe and effective treatment of major depression, one of the most common comorbid conditions in individuals infected with HIV, significantly lowers morbidity and mortality from HIV disease. However, optimal treatment of both conditions is complicated by interactions between the disease processes as well as the pharmacological agents used to treat them. In patients with HIV it may be difficult to distinguish major depression from other physiological and emotional states that present with similar symptoms. Accurate diagnosis of major depression is thus complex and essential to preventing inappropriate exposure of patients to potentially harmful psychotropic medications. This review outlines important initial steps in making this diagnosis. All patients with HIV should be screened for depression by their medical providers and referred to a psychiatrist for full evaluation when necessary. The mainstay of treatment for major depression in patients with HIV disease is pharmacotherapy. Depressed patients with HIV respond to the same wide variety of antidepressant-class medications as depressed patients without HIV, including tricyclic antidepressants, paroxetine, fluoxetine and trazodone. Notably, new studies have also shown that some psychiatric medications can inhibit HIV replication. No particular antidepressant medication is superior for the treatment of depressed HIV-infected patients; however, the most important component of treatment of major depression in HIV-disease is patient adherence, which is highly influenced by antidepressant adverse effects. This review outlines adverse effects of antidepressant-class medications that are of particular concern in HIV-infected patients and describes pharmacological strategies for overcoming these potential barriers to medication adherence. This review also describes situations in which some adverse effects of antidepressant-class medications may be safely exploited to benefit depressed patients with HIV disease. Potential interactions between antidepressant-class medications and HIV medications, as well as pharmacological treatment strategies for treating the psychiatric adverse effects of HIV medications, are also discussed.

Assessment of sexual functioning in depressed patients treated with mirtazapine: a naturalistic 6-month study

Antidepressant-induced sexual dysfunction is a frequent side effect which may greatly contribute to treatment non compliance. Mirtazapine has a pharmacological profile expected to result in a lack of sexual dysfunction. The main purpose of this 6-month open-label study was to evaluate the effects of mirtazapine on sexual function of a sample of depressed patients.

METHODS

Seventy-eight patients meeting DSM-IV criteria for major depression or adjustment disorder with depressed mood or with mixed anxiety and depressed mood, sexually active prior to the episode, were treated with mirtazapine (15-60 mg/day). Effectiveness was assessed using the 17-item Hamilton rating scale for depression (HAM-D-17), the Hamilton rating scale for anxiety (HAM-A) and the clinical global impression (severity and improvement) scales (CGI). Sexual function was evaluated with the psychotropic-related sexual dysfunction questionnaire (PRSexDQ) which detects clinical changes in sexual dysfunction.

RESULTS

Forty-eight patients (61.5%) were experiencing sexual dysfunction at baseline. A return to normal sexual functioning was observed in 27 of 38 (71.1%) patients completing the study. Significant reductions in mean total PRSexDQ scores were detected at day 90 and endpoint and only four patients withdrew or required dose reduction due to mirtazapine-induced sexual dysfunction. A total of 37 patients (47.4%) achieved complete remission of depression (HAM-D-17 score <or= 7) at endpoint. Only seven patients (9.0%) withdrew the study because of adverse events.

CONCLUSION

Mirtazapine showed in this study that it is an effective and well-tolerated antidepressant treatment with a possibly lower incidence of sexual side effects than other antidepressants.

A randomized, placebo-controlled, crossover study of ephedrine for SSRI-induced female sexual dysfunction

The objective of this study was to determine whether ephedrine, an alpha- and beta-adrenergic agonist previously shown to enhance genital blood flow in women, has beneficial effects in reversing antidepressant-induced sexual dysfunction. Nineteen sexually dysfunctional women receiving either fluoxetine, sertraline, or paroxetine participated in an eight-week, double-blind, placebo-controlled, cross-over study of the effects of ephedrine (50 mg) on self-report measures of sexual desire, arousal, orgasm, and sexual satisfaction. Although there were significant improvements relative to baseline in sexual desire and orgasm intensity/pleasure on 50 mg ephedrine 1-hr prior to sexual activity, significant improvements in these measures, as well as in sexual arousal and orgasmic ability also were noted with placebo. These findings highlight the importance of conducting placebo-controlled trials for this condition.

Mirtazapine orally disintegrating tablet versus sertraline: a prospective onset of action study

This multinational, randomized, double-blind study was specifically designed to prospectively compare the onset of antidepressant efficacy of mirtazapine orally disintegrating tablets and sertraline at dosages commonly used in clinical practice. A total of 345 patients with major depressive episode (DSM-IV) received mirtazapine (30-45 mg/d) or sertraline (50-150 mg/d) for 8 weeks. Mirtazapine was administered in the newly developed fast dissolving, orally disintegrating tablet formulation. Assessments were performed at baseline and on days 4, 7, 10, 14, 28, 42, and 56. The primary efficacy variable (mean absolute change from baseline in the Hamilton Depression Rating Scale [HAMD] total score [17 items]) showed that mirtazapine was significantly (P < 0.05) more effective than sertraline at all assessments during the first 2 weeks of the study. After this time, HAMD total scores were similar in both groups. These findings were supported by analysis of the HAMD response rate (ie, > or =50% reduction in HAMD total score from baseline), HAMD remission rate (HAMD total score of < or =7), and the Montgomery-Asberg Depression Rating Scale (MADRS). Both treatments were well tolerated. In addition, mirtazapine had a greater effect than sertraline on sexual functioning. In conclusion, this first prospective onset of action study using the orally disintegrating tablet indicates that mirtazapine has a faster onset of therapeutic effect than sertraline. The orally disintegrating tablet formulation of mirtazapine used in this study is known to enhance the convenience and compliance by the patient.

Neurochemical aspects of the sexual response cycle

What drives the human sexual response cycle? The human sexual response cycle is a highly complex phenomenon that encompasses many transmitters and transmitter systems centrally and peripherally. The endocrine system is also intricately involved in the brain and in the periphery organs. Integration of these systems is a function of the nervous system that ultimately produces a vast array of cognitive, emotional, physiological, and behavioral responses. Therefore, it is not surprising that a disturbance in even a single system will lead to dysfunction in one or more phases of the sexual response cycle. This article highlights the complex roles the aminergic system plays along with key hormones that are equally involved. The article also points out how rudimentary and fragmented our knowledge is in this field and how few controlled studies are available. The potential for development of specific agents that target selective sexual dysfunctions is exemplified in sildenafil, the first such agent ever to be brought to market.

Depression after stroke: a review of the evidence base to inform the development of an integrated care pathway. Part 2: Treatment alternatives

BACKGROUND

Depression is a common complication of stroke, leading to increased morbidity and mortality. It can impede the process of rehabilitation, and has been associated with poorer outcomes and increased length of stay in hospital. This systematic review was undertaken as a preliminary step to the development of an evidence-based integrated care pathway (ICP) for the management of post-stroke depression (PSD) in a rehabilitation setting, and is divided into two parts. In part 1 we reviewed the frequency of depression in stroke, its impact on functional recovery and the different methods for assessment.

AIMS AND OBJECTIVES

In part 2, we discuss the rationale for treatment of PSD, appraise the evidence for effectiveness of the different antidepressant drugs, and consider whether we can identify a recommended first-line treatment for use in our ICP.

METHODS

Data sources comprised a computer-aided search of published studies on depression in stroke and references to literature used in reviews.

MAIN FINDINGS

From the few controlled trials of anti-depressant therapy in PSD, both tricyclics and selective serotonin re-uptake inhibitors (SSRIs) appear to be effective, but the latter may be preferable in stroke because of their prompt action and better side-effect profiles. Within the group of SSRIs there is currently no direct evidence to guide the choice of agent. In the absence of firm guidance, sertraline was chosen on theoretical grounds as one of the most potent with minimal sedative effects and no reported interaction with warfarin. Citalopram may offer an appropriate second choice.

CONCLUSIONS

A suggested regimen for the use of sertraline in PSD was put forward. Development of an ICP may help to establish a more consistent approach to assessment and treatment of PSD, and form a basis for future comparison of different treatments as they become available.

Cyproheptadine versus propranolol for the treatment of acute neuroleptic-induced akathisia: a comparative double-blind study

The purpose of this study was to investigate the efficacy of cyproheptadine, an antiserotonergic agent, in the treatment of neuroleptic-induced akathisia (NIA), as compared with propranolol, the current gold standard. In a double-blind trial, 30 patients with schizophrenia and NIA received either cyproheptadine 16 mg/day (N = 18) or propranolol 80 mg/day (N = 12) for 4 days, followed by 3 days without any anti-NIA treatment. The Barnes Akahisia Scale, Simpson-Angus Extrapyramidal Effects Rating Scale, and Brief Psychiatric Rating Scale were used to assess the severity of NIA, parkinsonism, and psychosis, respectively. In both groups, the severity of NIA decreased significantly over time (cyproheptadine, -46%; propranolol, -42%), with no significant intergroup difference. The NIA symptoms worsened significantly when cyproheptadine and propranolol were discontinued. We conclude that cyproheptadine 16 mg/day is as effective as propranolol for the treatment of acute NIA. The antiakathisic effect of cyproheptadine may be mostly attributable to its serotonin antagonistic activity.

Update on female sexual function

In this review, we briefly discuss recently published data on female sexual desire, arousal, orgasm and pain, and on medical/iatrogenic factors associated with female sexual function. The studies reviewed highlight a number of important methodological and etiological issues in the study of female sexual function. Researchers are urged to use standardized methods for defining sexual disorders and for selecting patient samples. Placebo-controlled studies are essential for examining the pharmacological aspects of female sexual dysfunction. Evidence suggests that free testosterone levels may be associated with sexual desire in women. Sildenafil citrate increases genital blood flow but may not impact on subjective reports of arousal. Past research implicated the serotonin 5-hydroxytryptamine 2 and 5-hydroxytryptamine 1A receptors in female sexual function, while recent data suggest a role for the 5-hydroxytryptamine 3 receptor. Increasing attention is being paid to medical/health conditions that impact sexual function (e.g. neurological conditions, cancer, hysterectomy, and cardiovascular disease).

Management of psychiatric disorders in patients infected with human immunodeficiency virus

Psychiatric disorders increase the risk of acquiring human immunodeficiency virus (HIV) and increase morbidity from HIV-related illness by impeding treatment. The response to highly active antiretroviral therapies is impaired by poor patient adherence, a substantial component of which is related to mental illness and substance use disorders. The recognition of psychiatric disorders in most HIV clinics is an issue of utmost importance. We outline diagnostic and treatment issues for major depression, bipolar disorder, personality disorder, substance use disorders, and demoralization as seen in patients with HIV. Our experience at the Johns Hopkins Moore (HIV) Clinic has led us to conclude that treatment of these disorders greatly improves patient adherence to treatment and outcomes of HIV infection.

An overview of generalized anxiety disorder: disease state--appropriate therapy

OBJECTIVE

This article reviews the prevalence, diagnosis, and treatment of generalized anxiety disorder (GAD).

BACKGROUND

Patients with GAD often present to primary care physicians; frequently the disorder manifests with somatic symptoms that have no identifiable physiologic foundation. Accurate diagnosis and treatment often prove elusive, and health care resources are inappropriately consumed in the management of a wide array of complaints, including headache, noncardiac angina, fatigue, insomnia, or abdominal discomfort. Early diagnosis and intervention are critical; GAD is frequently associated with other anxiety and mood disorders, major depressive disorder among them. The differential diagnosis of GAD is complex, including medication side effects and substance-related dependence or withdrawal phenomena, as well as endocrine, neurologic, cardiorespiratory, and autoimmune disorders.

CONCLUSIONS

GAD is differentiated from adjustment disorder with anxiety because only GAD can manifest without identifiable emotional stressors; it is differentiated from panic disorder largely on the basis of the chronicity of GAD and the episodic, abrupt nature of panic attacks, with the involvement of at least 4 autonomic, cardiopulmonary, neurologic, or other symptoms. In addition to psychotherapy, education, lifestyle modifications, and social support, several pharmacologic agents may be appropriate therapy for GAD. Given the chronic, nonremitting, relapsing character of GAD, use of benzodiazepines, which confer short-term relief, is usually ill-advised in long-term treatment because these agents can impair cognitive and psychomotor function, interact with various central nervous system depressants (eg, alcohol), and exhibit substantial potential for abuse, tolerance, dependence, and withdrawal effects. Buspirone and certain antidepressants, including the dual noradrenergic-serotonergic reuptake inhibitor venlafaxine, represent first-line therapy for GAD.

Treating depression with selective serotonin reuptake inhibitors: a practical approach

Depression is a common disorder that is becoming better understood as an illness that can be chronic, recurrent, and refractory to treatment. Depression can produce substantial suffering and profoundly affect a patient's self-esteem, relationships, and functional capacity. The improved adverse-effect profile and safety from overdose of selective serotonin reuptake inhibitors (SSRIs) have led to treatment of milder forms of depression and thus increased treatment of depression overall. This article synthesizes several previously published reviews and psychopharmacology resources and addresses practical issues related to initiating, monitoring, continuing, and discontinuing SSRIs. Precautions related to SSRI use and important considerations for various types of depression are discussed.

Evaluating the Incidence of Antidepressant-Induced Sexual Dysfunction

The incidence of sexual dysfunction (SD) associated with antidepressants may be higher than the rate reported in the product information. We conducted a study using a survey that included the Arizona Sexual Experiences (ASEX) scale to assess the incidence of SD before and with current antidepressant use. We also set out to determine if differences exist between antidepressant classes. Forty-four patients (12 males and 32 females) responded to the survey. Data was stratified into 3 groups, selective serotonin reuptake inhibitors (SSRIs; n = 36), tricyclic antidepressants (TCAs; n = 7), and novel agents (bupropion and nefazodone, or NA; n = 7). For the SSRI subgroup, there were significant increases in ASEX scores, indicative of SD after treatment. There were no differences in ASEX scores in the TCA or NA group. The incidence of SD was highest for the SSRIs (36%). Clinical implications of these findings include educating patients, improving clinical assessment, and enhancing awareness about options available to manage antidepressant-induced SD.
