reduction of radiotherapy-induced OM pain... CONCLUSION: A doxepin rinse diminishes OM pain. Further studies are warranted to

Efficacy and safety of doxepin 3 and 6 mg in a 35-day sleep laboratory trial in adults with chronic primary insomnia. [2011.10.01]
STUDY OBJECTIVES: To evaluate the efficacy and safety of doxepin (DXP) 3 mg and 6 mg in adults diagnosed with primary insomnia... 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.

Doxepin cream vs betamethasone cream for treatment of chronic skin lesions due to sulfur mustard. [2011.05]
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...

Efficacy and Safety of Doxepin 1 mg and 3 mg in a 12-week Sleep Laboratory and Outpatient Trial of Elderly Subjects with Chronic Primary Insomnia. [2010.11]
STUDY OBJECTIVES: to evaluate the efficacy and safety of doxepin 1 mg and 3 mg in elderly subjects with chronic primary insomnia... 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.

Efficacy and Safety of Doxepin 1 mg and 3 mg in a 12-week Sleep Laboratory and Outpatient Trial of Elderly Subjects with Chronic Primary Insomnia. [2010]
elderly subjects with chronic primary insomnia... CONCLUSIONS: DXP 1 mg and 3 mg administered nightly to elderly chronic insomnia

Clinical Trials Related to Zonalon (Doxepin Topical)

Doxepin Hydrochloride in Treating Esophageal Pain in Patients With Thoracic Cancer Receiving Radiation Therapy to the Thorax With or Without Chemotherapy [Recruiting]
This pilot randomized clinical trial studies the effects, good and/or bad, of taking doxepin hydrochloride compared to placebo (inactive drug) in treating esophageal pain in patients with thoracic cancer receiving radiation therapy to the thorax with or without chemotherapy. Doxepin hydrochloride is a tricyclic antidepressant drug which was recently shown to be helpful for mouth pain in patients receiving radiation therapy. Part of doxepin hydrochloride's drug action takes place at the surface of the esophagus, which may be helpful in reducing the pain caused by radiation therapy.

Doxepin and a Topical Rinse in the Treatment of Acute Oral Mucositis Pain in Patients Receiving Radiotherapy With or Without Chemotherapy [Recruiting]
The purpose of this study is to test whether a mouthwash made with a drug called doxepin can reduce the pain caused by mouth sores resulting from radiation therapy. A number of mouth rinse preparations exist for patients with treatment-related oral mucositis pain such as the DLA rinse, an over-the-counter medication. This study will evaluate the effects of doxepin compared to DLA (diphenhydramine, lidocaine and antacids) and placebo. Doxepin is approved by the Food and Drug Administration (FDA) for the treatment of depression, anxiety, long-term pain management, as well as management of rash.

The Treatment of Insomnia in Patients With HIV Disease [Recruiting]
This study is designed to evaluate the efficacy of two commonly prescribed sleep aids for use in patients who are HIV positive and suffer from insomnia.

Treatments for Insomnia in Patients With Parkinson's Disease [Recruiting]
More than half of patients with Parkinson's have troubles with insomnia. There are several

treatment options for insomnia that have been studied in the general population - however,

the investigators don't know if these treatments work for patients with Parkinson's. It is possible that people with Parkinson's may have different treatment responses. The goal of this project is to test in a pilot study the tolerability and effectiveness of pharmacologic and non-pharmacologic treatments to improve insomnia in patients with Parkinson's disease. Each participant in this study will be wearing a wrist actigrapch and fill out the sleep diary. Three main treatment strategies will be tested: Placebo Light therapy, Cognitive behavioural therapy and active light therapy, and insomnia medications. The treatment that each person will receive first will be chosen randomly. If the first therapy has not been effective, participant may choose to re-enrol in the trial with one of the remaining two therapies.

YouScript IMPACT Registry [Recruiting]
This multicenter observational study aims to investigate the benefits of providing pharmacogenetic testing with the YouScript Personalized Prescribing System which includes a clinical decision support tool and individualized pharmacist recommendations to elderly polypharmacy patients who are most at risk of adverse drug events. The YouScript system is unique in identifying drug-gene, and drug-drug-gene interactions that are missed by existing systems, and represent over 35% of significant interaction warnings. Data analysis will assess the impact of recommendations for medication changes on clinical decision making, patient outcomes, and healthcare resource utilization to determine which medications, specialties, or patient segments derive the greatest benefit from this intervention. Data gathered from patients enrolled in this study will be compared to patients matched on key characteristics from Inovalon's MORE2 healthcare database.
