RESUMO

PURPOSE: This study sought to describe patient characteristics and treatment patterns among patients with insomnia prescribed trazodone in the United States. METHODS: This real-world, retrospective, descriptive cohort study used US commercial insurance claims from July 1, 2009, through June 30, 2019. The index date was the first prescription for trazodone between January 1, 2010, and December 31, 2018, with 6 months for the preindex period and ≥6 months for the postindex period. FINDINGS: Among 5.8 million patients with insomnia, 17.7% were prescribed trazodone, and 357,380 adults (6.2%) and 7564 children (0.1%) met the study eligibility criteria. The mean (SD) age was 48.8 (15.8) years for adults and 14.8 (2.7) years for pediatrics. Most patients were female (229,280 adults [64.2%] and 4481 children [59.2%]). Insomnia due to mental disorder was the most common specific diagnosis. The most common (>25%) comorbid conditions were anxiety, depression, and hypertensive disease, and 1 of 10 had a history of substance abuse. Zolpidem was previously prescribed (73,342 adults [20.5%] and 233 children [3.1%]) and continued to be prescribed. Concomitant antidepressants were most common (216,893 adults [60.7%] and 5414 children [71.6%]), but benzodiazepines (132,740 adults [37.1%] and 1188 children [15.7%]), antiepileptics (115,064 adults [32.2%] and 2103 children [27.8%]), nonbenzodiazepines (90,946 adults [25.4%] and 542 children [7.2%]), and antipsychotics (40,490 adults [11.3%] and 2063 children [27.3%]) were also prescribed. IMPLICATIONS: This study provides current evidence that trazodone use is widespread among patients with insomnia and is often associated with other specific comorbidities, such as psychiatric conditions. A deeper knowledge of the real-world management of patients with insomnia may facilitate steps toward improving sleep quality, daytime functioning, and clinical outcomes for patients.

RESUMO

PURPOSE: The primary objectives were to describe weight changes following initiation of lurasidone versus other antipsychotics and estimate the risk of clinically relevant (≥7%) weight changes. PATIENTS AND METHODS: This retrospective, longitudinal comparative cohort study was based on electronic medical records (EMRs) of United States (US) adult patients with schizophrenia who were prescribed lurasidone or other antipsychotics as monotherapy between 1 April 2013 and 30 June 2019. RESULTS: Overall, the study included 15,323 patients with a diagnosis of schizophrenia; 6.1% of patients received lurasidone, 60.4% received antipsychotics associated with a medium-high risk of weight gain (clozapine, olanzapine, quetiapine, risperidone, paliperidone) and 33.5% received antipsychotics with a low risk of weight gain (aripiprazole, first-generation antipsychotics, ziprasidone). Lurasidone was associated with the smallest proportion of patients experiencing clinically relevant weight gain and the greatest proportion of patients with clinically relevant weight loss. The risk of clinically relevant weight gain was numerically higher with all antipsychotics versus lurasidone and was statistically significant for olanzapine (hazard ratio [HR]=1.541; 95% confidence interval [CI]=1.121; 2.119; p=0.0078) versus lurasidone. The likelihood of ≥7% weight loss was significantly greater with lurasidone versus all antipsychotics (p<0.05), except ziprasidone. CONCLUSION: This real-world study suggests that lurasidone has a lower risk of clinically relevant weight gain and a higher likelihood of clinically relevant weight loss than other commonly used antipsychotics.

RESUMO

BACKGROUND: Painful diabetic neuropathy is an important therapeutic challenge as the efficacy of analgesic drugs in this setting is still unsatisfactory. Monotherapy with available treatments is often not sufficient and a combination of drugs is necessary. Trazodone (TRZ) is a compound with a multi-modal mechanism of action, being a serotonin-2 antagonist/reuptake inhibitor developed and approved for the treatment of depression in several countries. Previous clinical trials suggest a possible beneficial effect of low doses of trazodone for the treatment of patients affected by painful diabetic neuropathy. OBJECTIVE: This phase II study was designed to collect data on the efficacy and safety of low doses of TRZ combined with gabapentin after 8 weeks of treatment in patients affected by painful diabetic neuropathy. METHODS: This was a randomized, double-blind, placebo-controlled, multi-center, international, prospective study. Male and female diabetic patients aged 18-75 years and affected by painful diabetic neuropathy were eligible for enrollment. Subjects were randomized (1:1:1 ratio) to TRZ30 (10 mg three times daily for 8 weeks) or TRZ60 (20 mg three times daily for 8 weeks) or placebo. Gabapentin as background therapy was administered in open-label conditions to all patients. The primary endpoint was the change from baseline of the Brief Pain Inventory Short Form item 5 to week 8. Secondary endpoints included the other Brief Pain Inventory Short Form items, and the assessment of anxiety, sleep, quality of life, patient's improvement, and safety. RESULTS: One hundred and forty-one patients were included in the intention-to-treat population: 43 allocated to the TRZ30 group, 50 to the TRZ60 group, and 48 to the placebo group. After 8 weeks, the mean changes of Brief Pain Inventory Short Form item 5 from baseline were - 3.1, - 2.6, and - 2.5 in the TRZ30, TRZ60, and placebo groups, respectively. No statistically significant differences between groups were seen. Nevertheless, a better trend was observed for TRZ30 vs placebo (95% confidence interval - 1.30, 0.15; p = 0.1179), on top of the background effect of gabapentin administered to all study groups. 62.8% of patients achieved a ≥ 50% reduction in the TRZ30 group, 54% in the TRZ60 group, and 45.8% in the placebo group. At the same time, a statistically significant improvement was observed in Brief Pain Inventory Short Form item 6 for TRZ30 vs placebo (95% confidence interval - 1.54, - 0.07; p = 0.0314). No serious adverse event occurred during the trial and the most frequent treatment-emergent adverse events involved nervous system, QT prolongation, and gastrointestinal disorders. CONCLUSIONS: All treatment groups showed a clinically meaningful pain improvement; nevertheless, patients in the TRZ30 treatment group reported better efficacy outcomes. This finding suggests that low doses of TRZ could be useful for treating painful diabetic neuropathy, and support further adequately powered confirmatory trials investigating the efficacy of TRZ.
