Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00000661 ↗	The Pharmacokinetics of Zidovudine and Oxazepam Alone and in Combination in the HIV-Infected Patient	Completed	National Institute of Allergy and Infectious Diseases (NIAID)	Phase 1	1969-12-31	To determine if a pharmacokinetic (blood level) interaction exists between zidovudine (AZT) and oxazepam in the HIV-infected patient. Benzodiazepines (such as oxazepam) are among the most frequently prescribed class of drugs and are commonly used therapeutically for patients with chronic disease. This study is important because of the potential for toxicity resulting from a reaction between AZT and benzodiazepines and the likelihood of frequent use of the combination of these drugs in patients with HIV infection.
NCT00000897 ↗	A Study to Evaluate the Effects of Different Methods of Birth Control on the Drug Actions of Zidovudine (an Anti-HIV Drug) in HIV-Positive Women and to Compare Zidovudine Metabolism in Men and Women	Completed	National Institute of Allergy and Infectious Diseases (NIAID)	N/A	1969-12-31	The purpose of this study is to look at the effects of different methods of birth control (oral and injectable) on how the body absorbs, makes available, and removes zidovudine (ZDV). This study will also evaluate the differences in men and women in how the body absorbs, makes available, and removes ZDV. Past research has shown that the effectiveness of ZDV as an anti-HIV drug might be decreased in individuals who use certain methods of birth control. ZDV may also have different effects in men compared to women.
NCT00149110 ↗	Chronos: the Use of Chronobiological Treatment in Depression	Completed	Eli Lilly and Company	N/A	2005-09-01	The primary objective of the present study is to examine whether the combination of the antidepressant duloxetine and chronotherapeutic methods (including sleep deprivation, light therapy, and maintaining a regular sleep-wake rhythm) in patient with major depression, will induce an immediate improvement from depression and whether this antidepressive effect will be maintained in the long term (29 weeks). Patient will be randomised to the above mentioned treatment or to an active group receiving exercise.
NCT00149110 ↗	Chronos: the Use of Chronobiological Treatment in Depression	Completed	The County of Frederiksborg	N/A	2005-09-01	The primary objective of the present study is to examine whether the combination of the antidepressant duloxetine and chronotherapeutic methods (including sleep deprivation, light therapy, and maintaining a regular sleep-wake rhythm) in patient with major depression, will induce an immediate improvement from depression and whether this antidepressive effect will be maintained in the long term (29 weeks). Patient will be randomised to the above mentioned treatment or to an active group receiving exercise.

FAQs

Q1: How do recent safety concerns influence oxazepam’s market?
Recent safety alerts, particularly regarding dependence and fall risk in elderly patients, have led to tighter prescribing regulations and increased clinician caution, limiting growth but emphasizing safer use protocols.

Q2: Are there any approved new indications for oxazepam?
No. Current approvals focus on anxiety and short-term insomnia. Clinical trials exploring other indications are ongoing but have yet to result in regulatory approval.

Q3: How does the patent landscape affect oxazepam’s marketability?
Most formulations are off-patent and available as generics, exerting downward pressure on pricing and limiting incentives for R&D investments unless new formulations or uses are developed.

Q4: What are the alternatives to oxazepam for anxiety treatment?
SSRIs, SNRIs, buspirone, and non-benzodiazepine hypnotics like Z-drugs are key alternatives, often favored due to lower dependence risks.

Q5: What is the outlook for emerging markets?
