Abstract
OBJECTIVES Considering the prevalence of oral mucositis, we aimed to use the analgesic effects of doxepin with chitosan's antimicrobial and bio-adhesive nature to fabricate a nano-formulation for treating chemotherapy-induced oral mucositis. MATERIALS AND METHODS Nanogel was fabricated via ionic gelation and characterized. Sixty patients were randomly divided and received four different treatments for 14 days: diphenhydramine + aluminum-magnesium mouthwash (control), doxepin mouthwash (DOX MW), chitosan nanogel (CN), and doxepin/chitosan nanogel (CN + DOX). Lesions were assessed with four indices, National Cancer Institute (NCI), World Health Organization (WHO), World Conference on Clinical and Research in Nursing (WCCNR) and visual analog scale (VAS) before and 3, 7, and 14 days after interventions. Kruskal-Wallis test was used for pairwise comparison. RESULTS CN had semisolid consistency, uniform spherical shape, an average size of 47.93 ± 21.69 nm, and a zeta potential of + 1.02 ± 0.16 mV. CN + DOX reduced WHO, WCCNR, and VAS scores significantly more than the control three days after the intervention. Seven days after the intervention, CN + DOX reduced NCI and WCCNR considerably more than the control; it reduced WCCNR significantly more than CN. Fourteen days after the intervention, CN + DOX decreased NCI markedly more than the control. CONCLUSION Chitosan-based doxepin nano-formulation might be a promising alternative for routine treatments of oral mucositis.

Abstract
BACKGROUND Behavioural, cognitive, and pharmacological interventions can all be effective for insomnia. However, because of inadequate resources, medications are more frequently used worldwide. We aimed to estimate the comparative effectiveness of pharmacological treatments for the acute and long-term treatment of adults with insomnia disorder. METHODS In this systematic review and network meta-analysis, we searched the Cochrane Central Register of Controlled Trials, MEDLINE, PubMed, Embase, PsycINFO, WHO International Clinical Trials Registry Platform, ClinicalTrials.gov, and websites of regulatory agencies from database inception to Nov 25, 2021, to identify published and unpublished randomised controlled trials. We included studies comparing pharmacological treatments or placebo as monotherapy for the treatment of adults (≥18 year) with insomnia disorder. We assessed the certainty of evidence using the confidence in network meta-analysis (CINeMA) framework. Primary outcomes were efficacy (ie, quality of sleep measured by any self-rated scale), treatment discontinuation for any reason and due to side-effects specifically, and safety (ie, number of patients with at least one adverse event) both for acute and long-term treatment. We estimated summary standardised mean differences (SMDs) and odds ratios (ORs) using pairwise and network meta-analysis with random effects. This study is registered with Open Science Framework, https://doi.org/10.17605/OSF.IO/PU4QJ. FINDINGS We included 170 trials (36 interventions and 47 950 participants) in the systematic review and 154 double-blind, randomised controlled trials (30 interventions and 44 089 participants) were eligible for the network meta-analysis. In terms of acute treatment, benzodiazepines, doxylamine, eszopiclone, lemborexant, seltorexant, zolpidem, and zopiclone were more efficacious than placebo (SMD range: 0·36-0·83 [CINeMA estimates of certainty: high to moderate]). Benzodiazepines, eszopiclone, zolpidem, and zopiclone were more efficacious than melatonin, ramelteon, and zaleplon (SMD 0·27-0·71 [moderate to very low]). Intermediate-acting benzodiazepines, long-acting benzodiazepines, and eszopiclone had fewer discontinuations due to any cause than ramelteon (OR 0·72 [95% CI 0·52-0·99; moderate], 0·70 [0·51-0·95; moderate] and 0·71 [0·52-0·98; moderate], respectively). Zopiclone and zolpidem caused more dropouts due to adverse events than did placebo (zopiclone: OR 2·00 [95% CI 1·28-3·13; very low]; zolpidem: 1·79 [1·25-2·50; moderate]); and zopiclone caused more dropouts than did eszopiclone (OR 1·82 [95% CI 1·01-3·33; low]), daridorexant (3·45 [1·41-8·33; low), and suvorexant (3·13 [1·47-6·67; low]). For the number of individuals with side-effects at study endpoint, benzodiazepines, eszopiclone, zolpidem, and zopiclone were worse than placebo, doxepin, seltorexant, and zaleplon (OR range 1·27-2·78 [high to very low]). For long-term treatment, eszopiclone and lemborexant were more effective than placebo (eszopiclone: SMD 0·63 [95% CI 0·36-0·90; very low]; lemborexant: 0·41 [0·04-0·78; very low]) and eszopiclone was more effective than ramelteon (0.63 [0·16-1·10; very low]) and zolpidem (0·60 [0·00-1·20; very low]). Compared with ramelteon, eszopiclone and zolpidem had a lower rate of all-cause discontinuations (eszopiclone: OR 0·43 [95% CI 0·20-0·93; very low]; zolpidem: 0·43 [0·19-0·95; very low]); however, zolpidem was associated with a higher number of dropouts due to side-effects than placebo (OR 2·00 [95% CI 1·11-3·70; very low]). INTERPRETATION Overall, eszopiclone and lemborexant had a favorable profile, but eszopiclone might cause substantial adverse events and safety data on lemborexant were inconclusive. Doxepin, seltorexant, and zaleplon were well tolerated, but data on efficacy and other important outcomes were scarce and do not allow firm conclusions. Many licensed drugs (including benzodiazepines, daridorexant, suvorexant, and trazodone) can be effective in the acute treatment of insomnia but are associated with poor tolerability, or information about long-term effects is not available. Melatonin, ramelteon, and non-licensed drugs did not show overall material benefits. These results should serve evidence-based clinical practice.

Abstract
Mitochondrial protein FAM3A suppresses hepatic gluconeogenesis and lipogenesis. This study aimed to screen drug(s) that activates FAM3A expression and evaluate its effect(s) on hyperglycemia and steatosis. Drug-repurposing methodology predicted that antidepressive drug doxepin was among the drugs that potentially activated FAM3A expression. Doxepin was further validated to stimulate the translocation of transcription factor HNF4α from the cytoplasm into the nucleus, where it promoted FAM3A transcription to enhance ATP synthesis, suppress gluconeogenesis, and reduce lipid deposition in hepatocytes. HNF4α antagonism or FAM3A deficiency blunted doxepin-induced suppression on gluconeogenesis and lipid deposition in hepatocytes. Doxepin administration attenuated hyperglycemia, steatosis, and obesity in obese diabetic mice with upregulated FAM3A expression in liver and brown adipose tissues (BAT). Notably, doxepin failed to correct dysregulated glucose and lipid metabolism in FAM3A-deficient mice fed on high-fat diet. Doxepin's effects on ATP production, Akt activation, gluconeogenesis, and lipogenesis repression were also blunted in FAM3A-deficient mouse livers. In conclusion, FAM3A is a therapeutic target for diabetes and steatosis. Antidepressive drug doxepin activates FAM3A signaling pathways in liver and BAT to improve hyperglycemia and steatosis of obese diabetic mice. Doxepin might be preferentially recommended as an antidepressive drug in potential treatment of patients with diabetes complicated with depression.

Abstract
IMPORTANCE Oral mucositis causes substantial morbidity during head and neck radiotherapy. In a randomized study, doxepin mouthwash was shown to reduce oral mucositis-related pain. A common mouthwash comprising diphenhydramine-lidocaine-antacid is also widely used. OBJECTIVE To evaluate the effect of doxepin mouthwash or diphenhydramine-lidocaine-antacid mouthwash for the treatment of oral mucositis-related pain. DESIGN, SETTING, AND PARTICIPANTS A phase 3 randomized trial was conducted from November 1, 2014, to May 16, 2016, at 30 US institutions and included 275 patients who underwent definitive head and neck radiotherapy, had an oral mucositis pain score of 4 points or greater (scale, 0-10), and were followed up for a maximum of 28 days. INTERVENTIONS Ninety-two patients were randomized to doxepin mouthwash (25 mg/5 mL water); 91 patients to diphenhydramine-lidocaine-antacid; and 92 patients to placebo. MAIN OUTCOME AND MEASURES The primary end point was total oral mucositis pain reduction (defined by the area under the curve and adjusted for baseline pain score) during the 4 hours after a single dose of doxepin mouthwash or diphenhydramine-lidocaine-antacid mouthwash compared with a single dose of placebo. The minimal clinically important difference was a 3.5-point change. The secondary end points included drowsiness, unpleasant taste, and stinging or burning. All scales ranged from 0 (best) to 10 (worst). RESULTS Among the 275 patients randomized (median age, 61 years; 58 [21%] women), 227 (83%) completed treatment per protocol. Mucositis pain during the first 4 hours decreased by 11.6 points in the doxepin mouthwash group, by 11.7 points in the diphenhydramine-lidocaine-antacid mouthwash group, and by 8.7 points in the placebo group. The between-group difference was 2.9 points (95% CI, 0.2-6.0; P = .02) for doxepin mouthwash vs placebo and 3.0 points (95% CI, 0.1-5.9; P = .004) for diphenhydramine-lidocaine-antacid mouthwash vs placebo. More drowsiness was reported with doxepin mouthwash vs placebo (by 1.5 points [95% CI, 0-4.0]; P = .03), unpleasant taste (by 1.5 points [95% CI, 0-3.0]; P = .002), and stinging or burning (by 4.0 points [95% CI, 2.5-5.0]; P < .001). Maximum grade 3 adverse events for the doxepin mouthwash occurred in 3 patients (4%); diphenhydramine-lidocaine-antacid mouthwash, 3 (4%); and placebo, 2 (2%). Fatigue was reported by 5 patients (6%) in the doxepin mouthwash group and no patients in the diphenhydramine-lidocaine-antacid mouthwash group. CONCLUSIONS AND RELEVANCE Among patients undergoing head and neck radiotherapy, the use of doxepin mouthwash or diphenhydramine-lidocaine-antacid mouthwash vs placebo significantly reduced oral mucositis pain during the first 4 hours after administration; however, the effect size was less than the minimal clinically important difference. Further research is needed to assess longer-term efficacy and safety for both mouthwashes. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02229539.

Abstract
OBJECTIVE The aim of this study is to create a rank order of the comparative efficacy and acceptability (risk of all-cause discontinuation) of antidepressant treatment in poststroke depression (PSD) by integrating direct and indirect evidence. DESIGN Multiple-treatments meta-analysis of randomised controlled trials. PARTICIPANTS Patients with depression following stroke. INTERVENTIONS 10 antidepressants and placebo in the acute treatment of PSD. OUTCOME MEASURES The primary outcomes were the overall efficacy, defined as the mean change of the total depression score. The secondary outcome was the acceptability, defined as risk of all-cause discontinuation. These estimates as standardised mean differences or ORs with 95% CIs. RESULTS We identified 12 suitable trials, with data from 707 participants. All drugs were significantly more effective than placebo apart from sertraline, nefiracetam and fluoxetine. Most of the comparisons for acceptability revealed no significant differences except that paroxetine had significantly lower all-cause discontinuation than doxepin, citalopram and fluoxetine. Standardised mean differences compared with placebo for efficacy varied from -6.54 for the best drug (reboxetine) to 0.51 for the worst drug (nefiracetam). ORs compared with placebo for acceptability ranged from 0.09 for the best drug (paroxetine) to 3.42 for the worst drug (citalopram). For the efficacy rank, reboxetine, paroxetine, doxepin and duloxetine were among the most efficacious treatments, the cumulative probabilities of which were 100%, 85.7%, 83.2%, 62.4%, respectively. With respect to the acceptability rank, paroxetine, placebo, sertraline and nortriptyline were among the most acceptable treatments, the cumulative probabilities of which were 92.4%, 63.5%, 57.3%, 56.3%. CONCLUSION After weighing the efficacy and acceptability, we conclude that paroxetine might be the best choice when starting acute treatment for PSD, and fluoxetine might be the worst choice.

Abstract
Insomnia accounts for more than 5.5 million visits to family physicians each year. Although behavioral interventions are the mainstay of treatment, pharmacologic therapy may be necessary for some patients. Understanding the risks and benefits of insomnia medications is critical. Controlled-release melatonin and doxepin are recommended as first-line agents in older adults; the so-called z-drugs (zolpidem, eszopiclone, and zaleplon) should be reserved for use if the first-line agents are ineffective. For the general population with difficulty falling asleep, controlled-release melatonin and the z-drugs can be considered. For those who have difficulty staying asleep, low-dose doxepin and the z-drugs should be considered. Benzodiazepines are not recommended because of their high abuse potential and the availability of better alternatives. Although the orexin receptor antagonist suvorexant appears to be relatively effective, it is no more effective than the z-drugs and much more expensive. Sedating antihistamines, antiepileptics, and atypical antipsychotics are not recommended unless they are used primarily to treat another condition. Persons with sleep apnea or chronic lung disease with nocturnal hypoxia should be evaluated by a sleep specialist before sedating medications are prescribed.

Abstract
Psoriasis is a common chronic inflammatory skin disease observed in about 1-3% of the general population. About 60-90% of patients with psoriasis suffer from itching. Interestingly, in the past itch was not considered as an important symptom of psoriasis. Despite the high frequency of itch in psoriasis, the pathogenesis of this symptom is still not fully elucidated. Although most studies indicate neurogenic inflammation and the role of neuropeptides, other mediators may be important as well. The majority of psoriatic patients consider itch as the most bothersome symptom of the disease as it significantly alters daily functioning and psychosocial well-being. Patients with itch showed greater impairment of their health-related quality of life compared to those without itch, and the intensity of itch correlated with the degree of quality-of-life reduction. However, treatment options for itch in psoriasis are limited. Therapy of itch in patients with psoriasis should be directed toward the resolution of skin lesions, as disease remission usually is linked with itch relief. Recent studies have clearly pointed to an important role of apremilast and biologic agents in itch intensity reduction in subjects suffering from psoriasis. Other treatment modalities include antihistamines, especially with a sedative effect, narrowband ultraviolet B, and antidepressants (doxepin, mirtazapine, paroxetine). Support by family members and/or health professionals may also be of importance in helping psoriatic subjects cope with itch.

Abstract
INTRODUCTION The GABA(A) receptor agonist zolpidem has been used for treatment of insomnia since years, but special side effects have been reported. These side effects were called zolpidem-induced sleep-related complex behaviour. Such complex behaviour is associated with somnambulism and includes sleepwalking, sleep eating, sleep conversation and sleep driving. CASE PRESENTATION Two cases of zolpidem-induced sleep-related complex behaviour following self-intoxication, sleep driving and amnesia are presented. In both cases, the subjects reported the voluntary intake of only one zolpidem tablet of 10 mg and amnesia for the time afterwards. Shortly after the onset of the drug's action, both individuals drifted into a somnambulism-like state and toxicological blood analysis suggested the intake of the remaining zolpidem tablets which might be called "sleep intoxication". Later, the subjects were arrested by police after driving under drug influence and not realizing the situation. Retrospectively, both subjects suffered from psychiatric disorders and in case 2, the subject was treated for depression with doxepin. Consequently, these co-factors may have increased the risk for the occurrence of the sleep-related complex behaviour. DISCUSSION Involuntary self-intoxication should be taken into account in addition to the known pattern of zolpidem-induced complex behaviour. In legal cases, the forensic expert has to assess the blood concentration of zolpidem in evaluating this strange behaviour. CONCLUSION Amnesia and incoherence of speech, disorganization of behaviour, inability to realize the situation and mood changes may indicate a zolpidem-induced somnambulism-like state with sleep-related complex behaviour.

Abstract
STUDY OBJECTIVES To evaluate the efficacy and safety of doxepin (DXP) 3 mg and 6 mg in adults diagnosed with primary insomnia. DESIGN AND METHODS The study was a randomized, double-blind, parallel-group, placebo-controlled trial. Patients meeting DSM-IV-TR criteria for primary insomnia were randomized to 35 days of nightly treatment with DXP 3 mg (n=75), DXP 6 mg (n=73), or placebo (PBO; n=73), followed by 2 nights of single-blind PBO to evaluate discontinuation (DC) effects. Efficacy was assessed using polysomnography (PSG) and patient reports. Efficacy data were examined for Night (N) 1, N15, and N29. Safety assessments were conducted throughout the study. RESULTS Compared with PBO, DXP 3 and 6 mg significantly improved wake time after sleep onset (WASO) on N1 (3 mg and 6 mg; P<0.0001), N15 (3 mg P=0.0025; 6 mg P=0.0009), and N29 (3 mg P=0.0248; 6 mg P=0.0009), latency to persistent sleep (LPS) on N1 (3 mg P=0.0047; 6 mg P=0.0007), and total sleep time (TST) on N1 (3 mg and 6 mg P<0.0001), N15 (6 mg P=0.0035), and N29 (3 mg P=0.0261; 6 mg P<0.0001). In terms of early morning awakenings, DXP 3 and 6 mg demonstrated significant improvements in SE in the final quarter of the night on N1, N15, and N29, with the exception of 3 mg on N29 (P=0.0691). Rates of discontinuation were low, and the safety profiles were comparable across the 3 treatment groups. There were no significant next-day residual effects, and there were no spontaneous reports of memory impairment, complex sleep behaviors, anticholinergic effects, weight gain, or increased appetite. Additionally, there was no evidence of rebound insomnia after DXP discontinuation. CONCLUSIONS Five weeks of nightly administration of DXP 3 mg and 6 mg to adults with chronic primary insomnia resulted in significant and sustained improvements in sleep maintenance and early morning awakenings (with the exception of SE in the final quarter of the night on N29 for 3 mg [P=0.0691]). These sleep improvements were not accompanied by next-day residual effects or followed by rebound insomnia or withdrawal effects upon discontinuation. These findings confirm the unique profile of sleep maintenance efficacy and safety of DXP observed in prior studies.

Abstract
Disturbed sleep is a core symptom of depression and is among diagnostic criteria for depressive episode. Effects of an antidepressant drug on sleep are important for its clinical profile. Rapid improvement of sleep quality is particularly indicated in depressed patients with insomnia, anxiety, agitation and suicidal thoughts. The aim of the study was to evaluate the effects of trazodone on sleep in depressed patients in comparison to other sleep promoting antidepressants: agomelatine, amitriptyline, doxepin, mianserine and mirtazapine according to analysis of scientific publications. Sedative antidepressants including trazodone are regarded as treatment of choice in depression with agitation, anxiety or insomnia. They are also frequently used in low dose to promote sleep, as an alternative to hypnotics. Such approach to treatment of insomnia in depressed patients protects them against dependence on hypnotic drugs. Additionally, the antagonistic action of antidepressants on serotonergic 5-HT2 receptors improves not only the sleep continuity, but promotes also slow wave sleep. Trazodone and mirtazapine in comparison to many other antidepressants do not suppress REM sleep. Antidepressants have different effects on sleep. In treatment of depression sedative antidepressants should be administered in the full, recommended dose. However, if they are administered as concomitant treatment only to promote sleep, low doses are indicated. Too late administration time and too high dose are the most common factors related to failure of insomnia treatment with these drugs.

Abstract
Oral doxepin was shown to reduce chronic pruritus due to sulfur mustard. The present study compared the effects of topical doxepin 5% with betamethasone 1% for the treatment of pruritus in veterans exposed to sulfur mustard. This investigator-blinded, randomized, clinical trial was conducted in an outpatient dermatology clinic. Seventy-five men who were exposed to sulfur mustard 23 to 28 years ago during the Iran-Iraq war who complained of pruritus were randomized to receive doxepin cream 5% (n = 40) or betamethasone cream 0.1% (n = 35) twice a day for 6 weeks. Pruritus severity and Dermatology Life Quality Index (DLQI) were evaluated before and after each treatment. Both groups showed significant improvement regarding pruritus (P < .05), burning sensation, skin dryness (P < .001), and skin scaling (P < 0.05). The lesions of all regions significantly reduced after treatments (P < .05), except those on the head, face, and genitalia. Pruritus, visual analog scores, and DLQI significantly decreased (P < .01, P < .01, and P < .001, respectively) in doxepin- and betamethasone-treated groups, and there was no difference between groups. All DLQI subscores decreased after both type of treatments (P < .01). Equal efficacy of doxepin cream and betamethasone suggest that doxepin is a potential alternative to control pruritus caused by sulfur mustard in exposed veterans.

Abstract
STUDY OBJECTIVES to evaluate the efficacy and safety of doxepin 1 mg and 3 mg in elderly subjects with chronic primary insomnia. DESIGN AND METHODS the study was a randomized, double-blind, parallel-group, placebo-controlled trial. Subjects meeting DSM-IV-TR criteria for primary insomnia were randomized to 12 weeks of nightly treatment with doxepin (DXP) 1 mg (n = 77) or 3 mg (n = 82), or placebo (PBO; n = 81). Efficacy was assessed using polysomnography (PSG), patient reports, and clinician ratings. Objective efficacy data are reported for Nights (N) 1, 29, and 85; subjective efficacy data during Weeks 1, 4, and 12; and Clinical Global Impression (CGI) scale and Patient Global Impression (PGI) scale data after Weeks 2, 4, and 12 of treatment. Safety assessments were conducted throughout the study. RESULTS DXP 3 mg led to significant improvement versus PBO on N1 in wake time after sleep onset (WASO; P < 0.0001; primary endpoint), total sleep time (TST; P < 0.0001), overall sleep efficiency (SE; P < 0.0001), SE in the last quarter of the night (P < 0.0001), and SE in Hour 8 (P < 0.0001). These improvements were sustained at N85 for all variables, with significance maintained for WASO, TST, overall SE, and SE in the last quarter of the night. DXP 3 mg significantly improved patient-reported latency to sleep onset (Weeks 1, 4, and 12), subjective TST (Weeks 1, 4, and 12), and sleep quality (Weeks 1, 4, and 12). Several global outcome-related variables were significantly improved, including the severity and improvement items of the CGI (Weeks 2, 4, and 12), and all 5 items of the PGI (Week 12; 4 items after Weeks 2 and 4). Significant improvements were observed for DXP 1 mg for several measures including WASO, TST, overall SE, and SE in the last quarter of the night at several time points. Rates of discontinuation were low, and the safety profiles were comparable across the 3 treatment groups. There were no significant next-day residual effects; additionally, there were no reports of memory impairment, complex sleep behaviors, anticholinergic effects, weight gain, or increased appetite. CONCLUSIONS DXP 1 mg and 3 mg administered nightly to elderly chronic insomnia patients for 12 weeks resulted in significant and sustained improvements in most endpoints. These improvements were not accompanied by evidence of next-day residual sedation or other significant adverse effects. DXP also demonstrated improvements in both patient- and physician-based ratings of global insomnia outcome. The efficacy of DXP at the doses used in this study is noteworthy with respect to sleep maintenance and early morning awakenings given that these are the primary sleep complaints of the elderly. This study, the longest placebo-controlled, double-blind, polysomnographic trial of nightly pharmacotherapy for insomnia in the elderly, provides the best evidence to date of the sustained efficacy and safety of an insomnia medication in older adults.

Abstract
OBJECTIVE To critically review the body of clinical trials refuting or supporting the efficacy of topical antihistamines in the relief of pruritus. DESIGN Review of PubMed from January 1950 through September 2009 and the Cochrane Database of Systematic Reviews to identify therapeutic trials of topical antihistamines in the relief of pruritus. MAIN OUTCOME MEASURES All randomized controlled trials or clinical trials of topical antihistaminic compounds used in the treatment of pruritus. The authors found 19 trials throughout the literature. The quality of each trial was ranked by applying a modified version of Sackett's criteria for clinical evidence. Grade A trials are large, randomized, double-blind, placebo-controlled studies with low false-positive (alpha) and low false-negative (beta) errors. Grade B studies are also randomized, double-blind, placebo-controlled studies, but include a small number of patients. Grade C trials lack one or more of the following criteria: randomization, placebo control or blinding. RESULTS Only four large, randomized, double-blind, placebo-controlled clinical trials with definitive conclusions (grade A) support the use of topical antihistaminic agents, specifically topical doxepin, for relief of pruritus. Of seven grade B trials, four supported the efficacy of topical antihistamines while three refute their use in relieving pruritus. One grade B trial was inconclusive. All remaining trials (grade C) lacked placebo controls or randomization, or contained fewer than 20 patients in each treatment group. CONCLUSION While topical antihistamines are widely prescribed for the treatment of pruritus, the evidence to support their use is mixed. Topical doxepin has been demonstrated to reduce pruritus. Evidence is lacking, however, for other topical antihistamines, including diphenhydramine (Benadryl), that are widely used and available without a prescription.

Abstract
Neuropathic pain constitutes a serious therapeutic problem. In most cases polytherapy is necessary. Tramadol and antidepressants have common mechanisms of action and are frequently used together in clinical practice, thus interaction between them is very important. In the present study isobolographic analysis for equivalent doses of drugs was applied to examine the nature of interaction between tramadol and doxepin or venlafaxine in a neuropathic pain model in rats. Allodynia and hyperalgesia were assessed after intraperitoneal administration of each drug alone or in combination. Dose response curves were obtained and ED(50) doses were calculated. All drugs were effective in reducing thermal hyperalgesia and mechanical allodynia, however doxepin was more effective than venlafaxine. Combined administration of tramadol and doxepin demonstrated synergistic action in reducing thermal hyperalgesia and additive action in reducing mechanical allodynia. Combined administration of tramadol and venlafaxine showed additive action in reducing hyperalgesia and allodynia. Moreover, combined administration of tramadol and doxepin was more effective than combined administration of tramadol and venlafaxine. The experiments demonstrated that the nature of interaction between tramadol and doxepin is synergistic, which is not the case for tramadol and venlafaxine, what provides a valuable information referring to clinical practice, rationalizing administration of such drug combination.

Abstract
A 4-week randomized, double-blind safety and efficacy study was conducted to compare the safety and efficacy of cetirizine, doxepine, and hydroxyzine 5 in the treatment of chronic pruritus due to sulfur mustard. Patients were treated in the Dermatology Clinic of Baqiyatallah Hospital. The study population consisted of 75 patients with chronic pruritus due to sulfur mustard exposure. Patients were given either cetirizine 10 mg, doxepine 10 mg, or hydroxyzine 25 mg/day, for 4 weeks. A calculated pruritic score for each patient was taken before and 1 month after treatment. Mean before-treatment pruritic scores were 38.2 +/- 4.8, 37.2 +/- 4.9, and 37.3 +/- 5.1 in the cetirizine, doxepine, and hydroxyzine groups, respectively. After treatment, the mean pruritic scores were 24.8 +/- 3.1, 17.8 +/- 2.5, and 16.7 +/- 2.3 in the cetirizine, doxepine, and hydroxyzine groups, respectively. In addition, 65%, 75%, and 80% of patients in the cetirizine, doxepine, and hydroxyzine groups were downgraded in the severity of pruritus (P 1/4 0.465). Sedation effects were reported in 6, 14, and 18 patients in the cetirizine, doxepine, and hydroxyzine groups, respectively. Hydroxyzine 25 mg/day has equal results compared to doxepine 10 mg once daily; but greater than cetirizine 10 mg once a day in controlling the symptoms of patients with chronic pruritus.

Abstract
A 48-year-old woman with a major depression and treatment with doxepin was found comatose in her flat. Her son last saw her 48 h prior to being found. On arrival of the emergency physician, she presented a generalized seizure. The patient underwent endotracheal intubation and mechanical ventilation due to respiratory insufficiency and severe cyanosis. Empty packages of tablets (doxepin ca. 4000 mg and zolpidem 100 mg) were found in the flat. On hospital admission the doxepin blood concentration was 1.2 microg/ml. No life-threatening arrhythmia occurred at any time. On the advice of the poison information center, hemoperfusion was performed for extracorporeal elimination. Within several hours the doxepin blood concentration could be lowered to 0.8 microg/ml and although still above the therapeutic range the patient was extubated. However, the patient developed a generalized seizure which required re-intubation. As a consequence of the high distribution volume and re-distribution phenomena, the doxepin blood concentration had increased again to 1.2 microg/ml. Approximately 72 h later she was extubated again while the doxepin blood concentration was 0.9 microg/ml and 3 days later, the doxepin blood concentration was lowered to 0.3 microg/ml and the patient was transferred to the psychiatric ward the following day. This case report questions the efficacy of hemoperfusion during acute doxepin intoxication in the given constellation of a non-life-threatening arrhythmia.

Abstract
Fibromyalgia (FM) is still often viewed as a psychosomatic disorder. However, the increased pain sensitivity to stimuli in FM patients is not an "imagined" histrionic phenomena. Pain, which is consistently felt in the musculature, is related to specific abnormalities in the CNS pain matrix. Brain-derived neurotrophic factor (BDNF) is an endogenous protein involved in neuronal survival and synaptic plasticity of the central and peripheral nervous system (CNS and PNS). Several lines of evidence converged to indicate that BDNF also participates in structural and functional plasticity of nociceptive pathways in the CNS and within the dorsal root ganglia and spinal cord. In the latter, release of BDNF appears to modulate or even mediate nociceptive sensory inputs and pain hypersensitivity. We were interested, if BDNF serum concentration may be altered in FM. The present pilot study assessed to our knowledge for the first time BDNF serum concentrations in 41 FM patients in comparison to 45 age-matched healthy controls. Mean serum levels of BDNF in FM patients (19.6 ng/ml; SD 3.1) were significantly increased as compared to healthy controls (16.8 ng/ml; SD 2.7; p<0.0001). In addition, BDNF serum concentrations in FM patients were independent from age, gender, illness duration, preexisting recurrent major depression and antidepressive medication in low doses. In conclusion, the results from our study indicate that BDNF may be involved in the pathophysiology of pain in FM. Nevertheless, how BDNF increases susceptibility to pain is still not known.

Abstract
INTRODUCTION Pruritus is one of the frequent discomforting complications in patients with end-stage renal disease. We prospectively evaluated the effectiveness of doxepin, an H1-receptor antagonist of histamine, in patients with pruritus resistant to conventional treatment. MATERIALS AND METHODS A randomized controlled trial with a crossover design was performed on 24 patients in whom other etiologic factors of pruritus had been ruled out. They were assigned into 2 groups and received either placebo or oral doxepin, 10 mg, twice a day for 1 week. After a 1-week washout period, the 2 groups were treated conversely. Subjective outcome was determined by asking the patients described their pruritus as completely improved, relatively improved, or remained unchanged/worsened. RESULTS Complete resolution of pruritus was reported in 14 patients (58.3%) with doxepin and 2 (8.3%) with placebo (P < .001). Relative improvement was observed in 7 (29.2%) and 4 (16.7%), respectively. Overall, the improving effect of doxepin on pruritus was seen in 87.5% of the patients. Twelve patients (50.0%) complained of drowsiness that alleviated in all cases after 2 days in average. One patient refused to continue the treatment due to its sedative effect. CONCLUSIONS We suggest that doxepin, a tricyclic antidepressant with anti-H1 receptor effect, can help improve pruritus resistant to antihistamines in end-stage renal disease patients who undergo hemodialysis. A low dose of doxepin is safe while effective and its main adverse effect, drowsiness, is temporary and can be easily tolerated by the patients.

Abstract
Recent data suggest that inhibitory pathways may be involved in the pathophysiology of depression and in the mode of action of some antidepressant interventions. The aim of the present study was to test whether vagus nerve stimulation (VNS) can affect motor cortex excitability. Measures of motor cortical excitability were probed by using single-pulse and paired-pulse transcranial magnetic stimulation at baseline, after 10 weeks of left VNS, and additionally, in an on-off paradigm in 10 patients with treatment-resistant unipolar depression. Ten weeks of VNS was associated with a selective and pronounced increase in intracortical inhibition, whereas no changes occurred in the on-off paradigm. These results suggest that VNS is capable of changing motor cortical excitability in patients with depression.

Abstract
OBJECTIVE To compare the safety and efficacy of doxepin and hydroxyzine in the treatment of chronic pruritus due to exposure to sulfur mustard. METHODS In a randomized, double-blind safety and efficacy study, 50 patients with chronic pruritus were given either doxepin 10 mg/d or hydroxyzine 25 mg/d for 4 weeks. Pruritic score was calculated for each patient before treatment and 1 month after. RESULTS After treatment, the mean pruritic scores +/- SD of the hydroxyzine and doxepin groups were 16.7+/-2.3 and 17.8+/-2.5, respectively. The severity of pruritus was decreased in 80% of patients in the hydroxyzine group and 75% in the doxepin group (P=.786). Eighteen patients in the hydroxyzine group and 14 patients in the doxepin group reported sedation. CONCLUSIONS Both hydroxyzine and doxepin are effective and have equivalent results in controlling the symptoms of patients with chronic pruritus due to exposure to sulfur mustard.

METHODS 161 general practitioners and 162 psychiatrists in private practice documented 1319 patients, receiving doxepin for individual clinical reasons. Physicians were randomly divided into a guideline exposed and a control group. All physicians treated their patients according to individual clinical considerations. RESULTS Average maximum daily dosage was 83 mg/d in the control and 95 mg/d in the intervention group (F=19.15; p<0). Only 3% of patients in both groups got the recommended dosage of 150 mg/d. Guideline exposure resulted in increased dosages preferably for milder forms of depression and in comparatively lower rates of improvement. CONCLUSION Guideline exposure did not reach its goal in respect to the recommended dosage. It missed its goal in respect to improvement of outcome and even showed negative effects. Guidelines should be evidence-based not only by referring to literature reviews but by testing their clinical effects in controlled clinical trials.

Abstract
BACKGROUND Aromatic anticonvulsant agents such as carbamazepine and phenytoin can induce anticonvulsant hypersensitivity syndrome (AHS) at a frequency of 1 in 10,000 to 1 in 1,000 treated patients. The hypersensitivity syndrome is a potentially life-threatening adverse drug reaction with multiorgan involvement, and incidental reexposure must be strictly avoided. Patients and treating physicians must be informed and educated about the causal drug and its potential immunologic or toxicologic cross-reactivity with other compounds. It has been well established that for future antiepileptic drug therapy, carboxamides (carbamazepine and oxcarbazepine), phenytoin, and barbiturates (phenobarbital and primidone) have to be avoided owing to their high degree of cross-reactivity. Other anticonvulsant agents, such as valproic acid, benzodiazepines, and gabapentin, may be prescribed. OBJECTIVES To present the clinical data for and to describe the potential cross-reactivity between aromatic anticonvulsant and tricyclic antidepressant agents in patients with carbamazepine- and phenytoin-induced AHS. METHODS The knowledge of cross-reactivity among aromatic anticonvulsant agents mainly emerged from clinical experience and observations because diagnostic challenge tests are not advisable. Thirty-six patients with the diagnosis of AHS were instructed to contact our unit if the symptoms relapsed. RESULTS Despite better knowledge of AHS, one third of the patients had avoidable recurrences after exposure to cross-reactive drugs. Besides the known cross-reactivity among aromatic anticonvulsant agents, we observed a recurrence of the hypersensitivity syndrome in 5 patients after the administration of tricyclic antidepressant agents. CONCLUSION The important potential cross-reactivity between aromatic anticonvulsant and tricyclic antidepressant drugs should be brought to the attention of treating physicians.

Abstract
Herein, we present a case of a parkinsonism-hyperpyrexia syndrome (PHS) in a 58-year-old man with a 10-year history of Parkinson's disease. The patient presented with a 2-week history of fever and increasing confusion, in the context of a number of changes to his medication regimen. On presentation, he was noted to be febrile with autonomic instability, diaphoresis and marked rigidity. He was disoriented and responding to visual hallucinations. Investigations revealed an elevated creatine kinase and a provisional diagnosis of PHS was made. After the patient failed to respond during a 2-week period to supportive measures, electroconvulsive therapy (ECT) treatment was commenced. A good response to eight bilateral ECT treatments was achieved, with resolution of his confusional state and associated psychotic phenomena. We discuss the nosological and management issues associated with this case and discuss the role of ECT as a treatment modality in this condition.

Abstract
Atopic dermatitis (AD) is a common childhood skin disease that also affects adults. Sleep problems are frequently associated with AD and negatively affect both patients and their families. Although this problem is well recognized, there are currently limited studies of patients with AD to guide clinical management of sleep disturbances. This targeted review will inform clinicians of the potential therapeutic agents available to manage sleep disturbances and will review literature relevant to improving the sleep of children and adults with AD. On the basis of our clinical experience and the limited data available, we provide a suggested algorithm for clinicians treating sleep problems associated with AD, but clearly more studies are needed to both further characterize the sleep of patients with AD and to test the efficacy and effectiveness of candidate agents in clinical trials.

Abstract
Nephrogenic fibrosing dermopathy (NFD) is a newly recognized cutaneous fibrosing disorder. To date the etiology, pathogenesis, and clinical course remains unknown. The majority of cases have been in renal dialysis or renal transplant patients. Only four cases have been reported in which patients had acute renal failure and never required dialysis. Currently, there is no effective treatment. A 65-year-old man was hospitalized for pneumonia. During hospitalization he developed acute renal failure secondary to acute tubular necrosis. The patient had woody indurated plaques on his upper extremities and trunk, and brown indurated plaques on his trunk. Histopathological examination revealed a spindle cell proliferation infiltrating through the dermis and subcutis with mild mucin deposition. Nephrogenic fibrosing dermopathy is a novel fibrosing disorder diagnosed clinically and histopatholigically. Currently no risk factors other than renal failure have been identified. Our patient is a unique example of NFD observed in acute renal failure secondary to acute tubular necrosis, never requiring dialysis. We also review the four other cases of acute NFD never requiring dialysis that have been reported in the literature.

Abstract
A new pathophysiologically based classification of itch is proposed, which should help the clinician adopt a rational approach to diagnosis and management of generalized itch. Focusing on neurogenic itch (itch without visible rash), common causes are reviewed and guidelines for laboratory and radiologic investigation are proposed. A stepwise approach to the management of generalized itch resulting from systemic disease is recommended. Specifically, the relative merits of broad versus narrowband ultraviolet B (UVB) are discussed and the pros and cons of doxepin, opioid antagonists, and selective serotonin reuptake inhibitors (SSRIs) such as paroxetine are considered. Attention is drawn to some novel approaches, including bright-light phototherapy and molecular adsorbent recirculating system (MARS) for selected patients with intractable itch caused by hepatic failure, and mirtazapine for nocturnal itch.

Abstract
OBJECTIVE Doxepin is a tricyclic antidepressant formulated as a mixture of E-(trans) and Z-(cis) stereoisomers. Cytochrome P450 2D6 (CYP2D6) catalyzes the hydroxylation of E-doxepin and E-N-desmethyldoxepin stereospecically. There is evidence that tricyclic antidepressants might inhibit CYP2D6 activity but there is no data about the influence of doxepin on CYP2D6. MATERIALS AND METHODS Eleven patients diagnosed with depression according to ICD-10 criteria were included in the study. After wash-out period, before doxepin treatment, sparteine metabolic ratio (MR1) was assessed. After 2-weeks of doxepin treatment, MR2 was estimated. Sparteine and its metabolites were determined in urine by gas chromatographic method of Eichelbaum et al. RESULTS Based on MR1 values, 10 patients were classified as EM (extensive metabolizers) and 1 patient as PM (poor metabolizer). During the study, after doxepin treatment, none of patients has changed phenotype status. However, MR2 values were statistically significantly higher than MR1. CONCLUSION These results show the inhibitory effect of doxepin on CYP2D6 activity and may be of clinical value, especially in polymedicated patients treated with other CYP2D6 substrates or inhibitors.

Abstract
OBJECTIVE To investigate likelihood of self-harm by overdose with antidepressant drugs of different types by examining hospital admission data and poisons inquiries and relating them to prescribing. DESIGN Retrospective analysis of prospectively collected data on overdose admissions, poisons inquiries and prescribing of antidepressants in Edinburgh and Scotland. SETTING Poisons treatment unit of the Royal Infirmary of Edinburgh and its surrounding catchment for overdose cases and Scotland for poisons inquiries. PARTICIPANTS All patients admitted to the Royal Infirmary of Edinburgh between 1 January 2000 and 31 December 2002 with an overdose involving an antidepressant. MAIN OUTCOME MEASURES Overdose admissions (patients) in relation to prescribing in Edinburgh and poisons inquiries in relation to prescription rates in Scotland. RESULTS There were 1656 admissions involving 1343 patients. The likelihood of admission for an individual patient in relation to volume of prescribing (likelihood ratio: 95%CI) in the catchment was somewhat smaller for amitriptyline (0.83:0.74-0.92) and sertraline (0.79:0.63-0.99), and somewhat greater for mirtazapine (1.99:1.57-2.51), trazadone (1.30:1.09-1.54) and venlafaxine (0.97:1.81-1.16) [corrected] For poisons inquiries in Scotland, the excess for venlafaxine and mirtazapine was confirmed and likelihood of an inquiry lowest for selective serotonin re-uptake inhibitors (SSRIs). CONCLUSIONS There was no evidence of an excess likelihood of presentation with overdose with SSRIs, and the likelihood was reduced with sertraline. There was a small excess of both admissions and poisons inquiries for mirtazapine and venlafaxine. This is a concern in view of the increased toxicity of venlafaxine in overdose in comparison with SSRIs.

Abstract
The ideal antidepressant would control depression with no adverse effect on sexual function. Erectile dysfunction and other sexual dysfunction associated with antidepressant medication treatment are problems with many antidepressants and can lead to patient dissatisfaction and decreased compliance with treatment. A computerized MEDLINE search (English language, 1966-2003) was performed using the terms antidepressive agents, erectile dysfunction, and sexual dysfunction. Emphasis was placed on studies with specific sexual function measurements taken before and after treatment and placebo control. Mixed mediator, nonserotonergic antidepressants that block postsynaptic serotonin type 2 receptors (nefazodone, mirtazapine) or that primarily increase dopamine or norepinephrine levels (bupropion) were thought to be good choices for avoiding antidepressant-associated sexual dysfunction or for switching patients in whom antidepressant-associated sexual dysfunction emerged. Comparisons with serotonin reuptake inhibitors (SRIs) have revealed less desire and orgasm dysfunction with nonserotonergic bupropion, less orgasm dysfunction with nefazodone, and superior overall satisfaction with sexual functioning with bupropion or nefazodone. However, most of these studies have design flaws that make evidence-based claims of efficacy difficult to substantiate. Agents proposed for antidote use in antidepressant-associated sexual dysfunction have either not been studied in men or not proved efficacious in randomized placebo-controlled trials. Switching to and augmentation with bupropion or nefazodone have also not clearly shown efficacy in controlled trials and require care and monitoring to avoid SRI discontinuation symptoms and loss of antidepressant efficacy. Few proposed treatment options, apart from avoidance, have proved effective for antidepressant-associated sexual dysfunction, which can have negative consequences on depression management.

Abstract
RATIONALE In primary care, sedating antidepressants are often used for treating insomnia, although their underlying sleep-promoting mechanisms are only incompletely understood. Since enhanced evening and nocturnal plasma cortisol levels are supposed to maintain insomniac sleep complaints, a functional link between sleep and cortisol secretion in the mode of action of antidepressants in insomnia might be suspected. OBJECTIVES We therefore investigated the effects of the tricyclic antidepressant doxepin on nocturnal sleep and plasma cortisol concentration in ten patients (age 41.3+/-9.5 years) with chronic primary insomnia between 1700 hours and 0800 hours. METHODS Single infusions of placebo and 25 mg doxepin were applied following a double-blind, randomized cross-over design. Afterward, all patients received 25 mg doxepin p.o. for 3 weeks in an open-study design. RESULTS Both doxepin application forms improved sleep significantly and reduced mean cortisol levels from 9.0+/-1.7 microg/l (single placebo i.v.) to 7.5+/-1.6 microg/l (single doxepin i.v.) or 7.6+/-2.0 microg/l (subchronic doxepin p.o.). The duration of the quiescent period of the cortisol rhythm was significantly prolonged following both doxepin administrations compared with placebo. CONCLUSIONS The results implicate that the sleep-improving effects of doxepin are mediated at least in part by a normalization of hypothalamic-pituitary-adrenal axis functions. Although in some patients rebound insomnia and specific side effects must be considered, our findings give a further rationale for the use of antidepressants in the treatment of primary insomnia.

Abstract
Therapeutic drug monitoring (TDM) of tricyclic antidepressants (TCA) is established in the treatment of depression to optimize outcome and safety. However, there are few reports on TDM under naturalistic clinical conditions. In the present study, we investigated a TDM group (TDM) and a randomly assigned parallel group without TDM (no-TDM) while on TCA treatment. Serum levels were analyzed in both cohorts, but feedback and dose recommendation were only provided for the TDM group. Serum levels of TCA were assessed by high-performance liquid chromatography (HPLC). The outcome was measured weekly using the Hamilton Depression Rating Scale (HAMD), the Clinical Global Impressions Scale (CGI), and the UKU side-effect scale. 84 patients with depressive disorder according to DSM-IV were recruited in three centers (TDM, n = 43; no-TDM, n = 41; mean age 49.9 +/- 13.2 years, 63.1 % female). Patients were treated with either amitriptyline (n = 69) or doxepin (n = 15); the mean dosage at endpoint was 126 +/- 35 mg and 155 +/- 47 mg, respectively. The mean study duration was 21 +/- 8 days. Both groups improved according to HAMD (from 25.2 +/- 8.4 at baseline to 12.0 +/- 7.4 at endpoint) and CGI scores (68 % responders). Moderately severe or severe side effects occurred in 16 % of patients. Adequate dose adjustment was significantly higher in the TDM group (60 % vs. 46 %, p < 0.05); this led to a significantly higher rate of therapeutic serum levels in the TDM group (58 % vs. 44 %, p < 0.05). Direct effects of TDM were not found for effectiveness. Therapeutic TCA serum levels over weeks one to three, however, were associated with significantly better outcome at endpoint (p < 0.05) as measured with changes in the HAMD or CGI response rates from baseline to endpoint. Finally, considerable side effects occurred significantly more often when serum levels were above the therapeutic range (27 % vs. 11 %; p < 0.01). We conclude that treating depression with TCA can be optimized by early TDM, which is superior to clinical judgment on its own. Since the psychiatrists in charge were less than completely "compliant" to the recommendations provided together with serum levels, the effect could be more pronounced than this study shows. The results encourage further studies in order to optimize antidepressant pharmacotherapy when using TDM appropriately.

Abstract
Amitriptyline, nortriptyline, imipramine, doxepin, desipramine, protriptyline, trimipramine, and maprotiline are tricyclic antidepressants (TCAs) used orally in treating major depressive disorders. Recent studies showed that amitriptyline is more potent in blocking the sciatic nerve functions in vivo by local injection than bupivacaine, a long-acting local anesthetic. We therefore tested whether various TCAs could likewise act as local anesthetics in vivo after single injection via the rat sciatic notch. The duration of complete sciatic nerve blockade by TCAs and the time to reach full recovery were measured with neurobehavioral assays and compared with results from bupivacaine. Amitriptyline, doxepin, and imipramine at 5mM elicited a longer complete sciatic nerve blockade than did bupivacaine at 15.4mM (0.5%), whereas trimipramine and desipramine at 5mM produced a shorter blockade. In contrast, nortriptyline, protriptyline, and maprotiline failed to elicit complete sciatic nerve blockade. Thus, TCAs have very different efficacy as local anesthetics in vivo. The duration of rat sciatic nerve blockade in vivo by TCAs is not well correlated with the 50% inhibitory concentration (IC(50)) of TCAs in blocking human cardiac Nav1.5 Na(+) channels expressed in human embryonic kidney cells. With this in vitro expression system, TCAs appear more potent than bupivacaine as Na(+) channel blockers in Nav1.5 Na(+) channels. We suggest that the ability of TCAs to pass through various membrane barriers within peripheral nerve trunks is crucial to their local anesthetic efficacy in vivo. TCAs with a tertiary amine appear more effective in penetrating these membrane barriers than TCAs with a secondary amine.

Abstract
Oral doxepin rinse has been reported to provide pain relief in patients with oral mucosal lesions due to cancer or cancer therapy. The purpose of this study was to assess the anesthetic effect of doxepin oral rinse in normal subjects to identify the duration of effect and to contrast the anesthetic effect with reported pain relief in patients with oral mucosal lesions. Normal volunteers were provided a solution of doxepin (5 mg/mL) for oral rinsing. Oral numbness and adverse effects were recorded for a period of 4 h after rinsing. Doxepin rinse resulted in mucosal anesthesia in all subjects. Sedation/fatigue was reported in four of seven subjects. There were no taste complaints and no nausea reported. The limited duration of numbness/anesthesia in normal subjects compared with prior studies showing pain relief for more than 3 h in patients with mucosal lesions, suggests that the extended duration of pain relief in patients was due to analgesic effects rather than anesthetic effects. The majority of normal subjects reported sedation after use, but this was less common in patients with mucosal lesions.

Abstract
Cold urticaria is characterized by the development of urticaria, usually superficial and/or angioedematous reaction after cold contact. It was found predominantly in young women. The diagnosis is based on the history and ice cube test. Patients with a negative ice cube test may have represented systemic cold urticaria (atypical acquired cold urticaria) induced by general body cooling. The pathogenesis is poorly understood. Cold urticaria can be classified into acquired and familial disorders, with an autosomal dominant inheritance. Idiopathic cold urticaria is most common type but the research of a cryopathy is necessary. Therapy is often difficult. It is essential that the patient be warned of the dangers of swimming in cold water because systemic hypotension can occur. H1 antihistamines can be used for treatment of cold urticaria but the clinical responses are highly variable. The combination with an H2 antagonists is more effective. Doxepin may be useful in the treatment. Leukotriene receptor antagonists may be a novel, promising drug entity. In patients who do not respond to previous treatments, induction of cold tolerance may be tried.

Abstract
Psychotropic medications are an important treatment approach to mental health disorders; such disorders are common in the elderly population. Elderly patients are more likely to experience adverse effects from these agents than their younger counterparts due to age-related changes in pharmacodynamic and pharmacokinetic parameters. Because of these factors, inappropriate use of psychotropic medications in elderly patients has become a focus of concern. In general an agent is considered inappropriate if the risk associated with its use exceeds its benefit. Implicit and explicit criteria for inappropriate use of medications in the elderly have been created and include psychotropic agents. These criteria vary in their make-up but the explicit criteria tend to agree that amitriptyline, doxepin, and benzodiazepines that have long half-lives are not appropriate. Although explicit inappropriate medication criteria have been in existence since 1991, elderly patients continue to receive inappropriate psychotropic medications. A wide array of factors may be responsible for this practice. Provider-related causes include deficits in knowledge, confusion due to the lack of a consensus on the inappropriate psychotropic criteria, difficulties in addressing an inappropriate medication started by a previous provider, multiple prescribers and pharmacies involved in the care of a patient, negative perceptions regarding aging, and cost issues. Patients may contribute to the problem by demanding an inappropriate medication. Finally, the healthcare setting may inadvertently contribute to inappropriate prescribing by such policies as restrictive formularies or lack of reimbursement for pharmacists' clinical services. Successful approaches to optimising prescribing have been either educational or administrative. Educational approaches (e.g. one-on-one sessions, academic detailing) seek to influence decision making, while administrative approaches attempt to enforce policies to curtail the undesired practice. The US Omnibus Budget Reconciliation Act of 1987, which improved psychotropic medication use in long-term care, is an excellent example of administrative intervention. More research specifically focused on the causes of inappropriate psychotropic medication use and methods to avoid this practice is needed before targeted recommendations can be made.

Abstract
(1) Report of severe adverse effects in infants from drugs passing into breast milk are rare. (2) Two reports of neurological disorders in infants due to doxepin, a tricyclic antidepressant, necessitating hospitalisation, serve as a reminder that this risk exists. (3) Epidemiological data are almost non existent. A prospective follow-up study of more than 800 breast-fed infants whose mothers were taking medicinal drugs showed minor adverse effects in 11% of the children (mainly diarrhoea, drowsiness and irritability). None of the mothers sought medical advice. (4) When a breast-feeding mother requires drug therapy, all available information should be weighed up before advising her to switch to bottle feeding.

Abstract
Smoking-related disease is the single biggest preventable cause of morbidity and mortality in the United States, yet approximately 25% of Americans continue to smoke. Various dosage forms of nicotine replacement therapy increase smoking quit rates relative to placebo, but they generally do not result in 1-year quit rates of over 20%. To increase these rates, a number of nonnicotine agents have been investigated. Drugs that modulate noradrenergic neurotransmission (bupropion, nortriptyline, moclobemide) are more effective than those affecting serotonin (selective serotonin reuptake inhibitors, buspirone, ondansetron) or other neurotransmitters.

Abstract
Oral mucositis is a treatment limiting toxicity of cancer therapy. The purpose of this study was to assess the impact of doxepin oral rinse in the management of oral mucosal pain in cancer patients. Forty-one cancer patients with oral mucosal pain were provided a solution of doxepin (0.5%) for oral rinsing. Oral pain was assessed prior to rinsing, and following rinsing for 4 h using a visual analogue scale (VAS). Adverse effects were recorded. Doxepin rinse resulted in a reduction of pain intensity of more than 50%, with pain relief extending for more than 3 h with pain not returning to baseline 4 h after rinsing. The rinse was tolerated by patients with mucosal damage, and had acceptable taste, and infrequent mucosal stinging with use. Some patients reported sedation after use, likely due to systemic absorption. The results of this single dose trial suggest that topical doxepin rinse has significant ability to provide clinically significant pain relief in patients with mucosal damage with an extended duration of effect.
