Clinical trial overview
These studies look at Ropivacaine Hydrochloride in many different clinical settings, mainly for pain control around surgery and other procedures.[1] The trials aim to measure whether it improves pain relief, recovery, mobility, or the need for extra pain medicine.[1]
Most of the listed trials are Phase 3 studies, which means they are later-stage studies that test treatments in larger groups of patients.[1] A smaller number are low-intervention studies or a Phase 2 study.[1]
Conditions and procedures being studied
The trials cover a wide range of conditions, including acute low back pain, hip osteoarthrosis, breast cancer surgery, lumbar arthrodesis, tonsillectomy, urolithiasis, total hip arthroplasty, knee osteoarthritis, and chronic neuropathic pain after mastectomy.[1]
Several studies focus on specific operations, such as cesarean section, cardiac surgery, hernia repair, shoulder surgery, hand surgery, colon surgery, renal surgery, and periacetabular osteotomy.[1] Others study pain after procedures like closed reduction of wrist fractures or treatment of hemorrhoidal disease.[1]
Some trials also include people with cancer-related conditions, such as advanced epithelial ovarian cancer, renal cancer, breast cancer, colorectal cancer surgery, and severe refractory cancer pain.[1]
Who may take part
Participants vary by study, because each trial is designed for a specific group of patients.[1] Some trials include people having planned surgery, while others include emergency patients, pregnant women in labor, or people with ongoing pain conditions.[1]
Examples of target groups include patients with acute low back pain, patients undergoing total hip or knee replacement, women having mastectomy, and people needing regional pain blocks for orthopedic or abdominal surgery.[1] One study also focuses on healthy volunteers to compare nerve block methods.[1]
Some trials are very specific about who can join. For example, one study includes pregnant women who request epidural analgesia for labor, while another includes patients needing subpectoral implantation of cardiac implantable electronic devices.[1]
Main outcomes and endpoints
The main outcomes often measure how much pain a patient has after the procedure, using tools such as the Visual Analog Scale (VAS) or the Numeric Rating Scale (NRS).[1] These are simple pain scores where a higher number usually means more pain.[1]
Several trials also measure the time until the first request for rescue analgesia, which means extra pain medicine given when the main treatment is not enough.[1] Other endpoints include return of sensory and motor function, postoperative recovery scores, mobility, bleeding during surgery, and quality of life.[1]
Examples of study-specific outcomes include pain reduction 30 minutes after a block, pain during the first 72 hours after tonsillectomy, pain at 24 hours after surgery, and the time from surgery or anesthesia to the first need for extra pain medicine.[1]
Trial phases and study designs
Most studies are interventional studies, meaning the research team gives a treatment or procedure and then measures the result.[1] Many are randomized or double-blind, which helps reduce bias by making comparisons fairer.[1]
The most common phase is Phase 3, with studies comparing Ropivacaine Hydrochloride against placebo, saline, or another pain method such as bupivacaine, lidocaine, clonidine, dexmedetomidine, or magnesium sulfate.[1] There is also a Phase 2 study in healthy volunteers looking at nerve block effects.[1]
Some studies are marked as completed, some as authorised, and a few were withdrawn before completion.[1]
What Ropivacaine Hydrochloride is compared with
In many trials, Ropivacaine Hydrochloride is tested against placebo, which is an inactive comparison treatment such as saline.[1] This helps show whether the pain relief comes from the study treatment itself.[1]
Other trials compare it with different local anesthetics or with a nerve block technique that uses another medicine mix.[1] Examples include comparisons with bupivacaine, lidocaine, levobupivacaine, and combinations with adjuvants such as magnesium sulfate, dexmedetomidine, or clonidine.[1]
Some studies do not compare the drug alone, but instead test whether adding Ropivacaine Hydrochloride to a block or infiltration method improves recovery, comfort, or pain scores after surgery.[1]
Selected trial examples
Acute low back pain: One Phase 3 study tests an erector spinae plane block to reduce pain and help patients move sooner after treatment, with outcomes measured 30 minutes after the procedure.[1]
Total hip arthroplasty: Several Phase 3 studies look at postoperative pain, return of sensory and motor function, walking ability, and the need for rescue pain medicine after hip replacement surgery.[1]
Breast surgery: Some trials study pain control after mastectomy or other breast cancer surgery using nerve blocks that include Ropivacaine Hydrochloride.[1]
Labor analgesia: One Phase 3 study includes pregnant women requesting epidural pain relief during labor and measures whether the sensory block is complete enough after 45 minutes.[1]
Abdominal and colorectal surgery: Trials in hernia repair, colon surgery, and colorectal cancer surgery measure postoperative recovery, pain scores, and morphine use.[1]
