Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00562627 ↗	Efficacy of Multimodal Peri- and Intraarticular Drug Injections in Total Knee Arthroplasty	Completed	Asker & Baerum Hospital	Phase 4	2007-11-01	Total knee arthroplasty (TKA) is associated with moderate to severe postoperative pain, causing patient discomfort, mobilisation and hospital discharge. The aim of this study is to: 1. Compare analgetic efficacy of to types of local infiltration analgesia in total knee arthroplasty. 2. Compare analgetic efficacy of local infiltration analgesia with continuous epidural analgesia.
NCT00573963 ↗	Efficacy of the Transversus Abdominus Plane (TAP) Block for Post-Cesarean Delivery Analgesia	Completed	Samuel Lunenfeld Research Institute, Mount Sinai Hospital	N/A	2007-12-01	The purpose of this study is to determine if patients having the transversus abdominal place (TAP) block at the end of a cesarean delivery have less pain in the post-delivery period than those who do not. Freezing medication is injected between the layers of muscle on either side of the belly, to freeze the nerves that carry pain stimuli from an abdominal wound. This technique has been useful for many abdominal operations, and has recently been studied in cesarean sections, however more information is needed.
NCT00603083 ↗	Postoperative Pain Treatment in Total Hip Arthroplasty: A Study to Assess the Effect of Local Analgesia	Completed	Vejle Hospital	Phase 4	2008-01-01	The purpose of this study is to determine whether the investigator standardized pain treatment plus local pain treatment is more effective than the investigator standardized pain treatment plus placebo in total hip arthroplasty.
NCT00702416 ↗	Ultrasound Guidance for Interscalene Brachial Plexus Block	Completed	University of Parma	Phase 4	2008-05-01	This study has been designed to assess the possible advantages of using ultrasound imaging to block the brachial plexus (i.e., nerves of the upper limb) in patients undergoing shoulder surgery. The ultrasound technique will be compared with the current gold standard, electrical nerve stimulation. The aim of this study is to define which technique is better in terms of time to onset of anesthesia.
NCT00724035 ↗	Ultrasound-Guided Axillary or Infraclavicular Nerve Block for Upper Limb Surgery	Completed	University of Parma	Phase 4	2008-05-01	This study aims to detect differences in onset time of brachial plexus (i.e., arm) anesthesia using two different nerve block techniques. Using ultrasound guidance, axillary (i.e., at the armpit) and infraclavicular (i.e., below the collarbone) blocks will be performed to patients undergoing upper limb surgery. The investigators will analyze how long it takes for anesthesia to be adequate for pain-free surgery, thus determine the optimal technique for this kind of surgery.
NCT00868348 ↗	A Comparison of Naropin and Ketorolac for Postoperative Analgesia After Total Knee Arthroplasty	Completed	University of Aarhus	Phase 4	2009-05-01	The purpose of this study is to determine wether ketorolac is effective in the treatment of postoperative pain after total knee arthroplasty
NCT00987441 ↗	Epidural Labor Analgesia and Infant Neurobehavior	Completed	Nanjing Medical University	N/A	2009-09-01	Infant neurobehavior alteration is predictor of later intelligence development. Many factors would influence or are associated with infant neurobehavior, of which exist or appear during perinatal period. Neuraxial, especially epidural, analgesia to date is the most effective method in relieving labor pain. Although previous studies showed that opioid used in epidural analgesia for labor pain can affect newborn neurobehavior negatively in a dose-escalation associated manner, whether epidural analgesia itself would produce unpredictable effect on newborn neurobehavior is still unknown. Hereby the investigators designed this trial to investigate the hypothesis that epidural analgesia for labor pain control itself would not produce negative effect on infant neurobehavior.

Introduction

Naropin, generically known as ropivacaine, is a local anesthetic primarily used in surgical, obstetric, and pain management procedures. Controlled and marketed by AstraZeneca, Naropin enjoys widespread use owing to its favorable safety and efficacy profile. As a crucial component within local anesthetics, the drug landscape surrounding Naropin is evolving, driven by ongoing clinical research, regulatory activity, and market dynamics.

This analysis synthesizes the latest clinical trial developments, assesses current market trends, and projects future growth avenues for Naropin.

Clinical Trials Update

Recent Clinical Trials and Developments

The global focus on optimizing anesthetic techniques has propelled numerous clinical trials involving ropivacaine, including formulations such as nerve blocks, epidural infusions, and peripheral infiltrations. Notably:

• Enhanced Recovery Protocols: Recent studies (e.g., [1]) explore ropivacaine's role in multimodal analgesia, aiming for reduced opioid consumption and faster postoperative recovery. These trials affirm Naropin’s safety profile and its efficacy in regional anesthesia protocols.

• Extended-Duration Formulations: Investigations are ongoing into sustained-release formulations of ropivacaine, potentially allowing extended analgesia with a single dose. For instance, phase I/II trials evaluate nanoparticle-based or liposomal delivery systems (e.g., [2]), promising to extend Naropin's duration of action significantly.

• New Indications and Applications: Trials are exploring off-label and novel uses—such as intra-articular injections post-arthroplasty ([3]) and in chronic pain management. Such studies could expand Naropin's utilization spectrum.

Regulatory and Safety Data

Regulatory agencies continue to evaluate the safety profiles of newer formulations. Recent peer-reviewed publications and post-marketing surveillance data reinforce Naropin's safety, with adverse events primarily limited to transient neurotoxicity and hypotension at higher doses. No significant safety signals have emerged ([4]).
