Plain English summary of protocol
Background and study aims:
Radicular pain is a type of pain that is caused by compression of a nerve in the spine. The pain is often felt in the area of the body that is supplied by that nerve, such as leg pain caused by compression of a nerve supplying the leg. Around 10-15% of patients with radicular pain undergo surgery to correct the problem eventually, however most use pain relieving drugs to control the pain levels. Diosmin is a type of plant chemical found mainly in citrus fruits, which is used for treating various conditions. It is thought to work by reducing inflammation (swelling). The aim of this study is to find out whether treatment with Diosmin may be effective in the treatment of radicular pain.
Who can participate?
Adults who have been diagnosed with radicular pain
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group are treated with Diosmin for one month. Those in the second group are treated with a commonly used pain relieving treatment for one month. Participants in both groups are asked to rate their pain levels and satisfaction with treatment when they first receive their treatment and again after two and eight weeks.
What are the possible benefits and risks of participating?
Participants who receive the Diosmin may benefit from a reduction in pain and greater levels of satisfaction. There are no notable risks involved with participating.
Where is the study run from?
Nanjing Drum Tower Hospital (China)
When is study starting and how long is it expected to run for?
March 2008 to December 2011

| Scientific title | A randomized controlled trial evaluating the effects of Diosmin in the treatment of radicular pain caused by lumbar intervertebral disc protrusion |
| Study objectives | Diosmin at a dose of 50 mg/kg/day may reduce the radicular pain from lumbar intervertebral disc protrusion and has no effect difference with currently used active treatment of mannitol plus dexamethasone. |
| Ethics approval(s) | Ethics Committees of Drum Tower Hospital of Nanjing University Medical School, 30/08/2008, ref: DTH-2017010 |
| Health condition(s) or problem(s) studied | Radicular pain |
| Intervention | Participants are randomised to one of two groups using a single randomisation technique. Intervention group: Participants receive Diosmin (Nanjing Chia Tai Tianqing Pharmaceutical Co., Ltd) per os, 900 mg, tid for 2 weeks followed by bid for 2 weeks, and lastly 450 mg bid as maintenance dose for at least one month. Control group: Participants receive 20% mannitol (CR Double-Crane Pharmaceuticals Co., Ltd) 250ml (1g/kg/day) and dexamethasone (Furuitang Pharmaceutical Co., Ltd) 10 mg/day intravenous drops for the first 3 days and followed by mannitol for 4 days. In the both groups, the course of treatment lasts for at least one month. Participants in both groups rate their pain levels and satisfaction with treatment at initial drug administration and after two and eight weeks. |
| Intervention type | Drug |
| Phase | Phase IV |
| Drug / device / biological / vaccine name(s) | Diosmin |
| Primary outcome measure(s) |
1. Perceived pain is measured using a visual analogue scale (VAS) and a numerical rating scale (NRS) just after the administration of drugs, and two and eight weeks later |
| Key secondary outcome measure(s) |
Patient’s satisfaction is measured using a three-grade scale ranging from completely satisfied (no pain at all time and no restriction of activities) to satisfied (slight pain that requires no medication and mild restriction of activities) to unsatisfied (moderate to severe pain that requires medication and moderate to severe restriction of activities) via telephone after two years. |
