What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only This study
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at whether adding tramadol or magnesium to a standard local anesthetic (ropivacaine) for a nerve block can better control pain during and after robotic prostate removal. Ninety men aged 40-80 will be randomly assigned to receive one of three solutions: ropivacaine alone, ropivacaine plus tramadol, or ropivacaine plus magnesium. Researchers will measure pain levels and painkiller use in the first 24 hours and follow up at 3 and 6 months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
tramadol and magnesium added to ropivacaine for a nerve block
What this could lead to
If it works, this could lead to better pain control after robotic prostate surgery, reducing the need for strong painkillers.
What could go wrong
This is a small, early-stage study with only 90 participants. The added drugs may not improve pain relief or could cause side effects like nausea.

Study facts

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 90 people

The number the study aims to enrol. It can still change while the study runs.

Started

Dec 2025

Expected to finish

Dec 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

40 to 80 years

Sex

Male participants only

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * males * age 40-80 years * physical status I-III according to the American Society of Anesthesiologists (ASA physical status) * undergoing robotic-assisted radical prostatectomy using Da Vinci Xi. Exclusion Criteria: * Patients allergic to ropivacaine, tramadol, magnesium, or other drugs used in the study * with coagulation disorders due to disease or medication, * inflammation at the site of the block, * addiction to alcohol * history of opioid tolerance * patients unable to complete the pain assessment scale * patients unable or unwilling to provide written consent to participate in the study.
