Summary

This trial is testing a new pain medication called clonidine micropellet, given as a single injection, to help people with low back and leg pain from sciatica. The medication aims to reduce pain by blocking pain signals in the nervous system. Clonidine has been used for many years to treat hypertension and chronic pain, with recent interest in topical formulations to limit adverse events.

Who is the study for?
Adults aged 18-70 with sciatica pain (leg pain ≥4, extending below the knee) for at least 8 weeks but less than 9 months, due to a specific type of lumbar disc issue confirmed by MRI. Participants must not have had recent pain relief and should be able to distinguish back from leg pain. Pregnant women or those planning pregnancy are excluded, as well as individuals with certain medical conditions or treatments that could affect study results.
What is being tested?
The trial is testing clonidine micropellets delivered via a single epidural injection using a Tuohy needle to treat low back and leg pain caused by sciatica. The effectiveness of this new medication will be compared against a sham injection in participants.
What are the potential side effects?
Potential side effects may include reactions at the injection site such as soreness or infection, lower blood pressure, dizziness due to hypotension, slow heart rate (bradycardia), and possibly other systemic effects related to clonidine's action on nerve pathways.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Sciatica treatments often target pain relief and inflammation reduction. Alpha-2 adrenergic agonists, such as clonidine, work by stimulating alpha-2 receptors in the central nervous system, which inhibits the release of norepinephrine and reduces pain signals. This mechanism is particularly relevant for Sciatica patients as it can provide significant pain relief without the sedative effects of other medications. Other common treatments include NSAIDs, which reduce inflammation and pain by inhibiting cyclooxygenase enzymes, and physical therapies that improve mobility and reduce nerve compression. Understanding these mechanisms helps patients and doctors choose the most effective and appropriate treatment options for managing Sciatica symptoms.
