All Clinical Trials for CARBOCAINE

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT01981291 ↗	Duration of Sciatic Nerve Block After Injection of Local Anesthetic In or Around the Nerve	Completed	University of Parma	Phase 4	2012-10-01	This study was designed to assess whether the injection of local anesthetic into the nerve (intraneural), as opposed to around it (perineural), leads to longer anesthesia and analgesia of the leg. Some reports of accidental intraneural injection mention an extremely long duration. When different drugs and doses were evaluated in a clinical trial of intraneural injection, a longer-than-expected duration was reported. The investigators will compare the two types of injection using the same drug, so as to determine if there is an actual difference in duration.
NCT02384915 ↗	Spinal Anesthesia Versus Combined Sciatic-femoral Nerve Block for Outpatient Knee Arthroscopy	Completed	ASST Gaetano Pini-CTO	Phase 4	2015-01-01	The aim of the study is to compare the time of home discharge in day-case patients receiving either a spinal anesthesia or a combined sciatic-femoral nerve block for knee arthroscopy
NCT02829697 ↗	The Effect of Local Anaesthetic Volume on Nerve Block Duration and Nerve Block Duration Variability	Completed	Innovation Fund Denmark	Phase 4	2016-07-01	The aim is to investigate the effect of perineural administration of a series of different volumes of local anaesthesia (ropivacaine 0.2%) on nerve block duration and the variability of the duration in the common peroneal nerve and the sciatic nerve in healthy volunteers. The hypothesis is that nerve block duration is correlated to local anaesthetic volume, but only to a certain degree. After a sufficient volume a 'saturation level' will be reached, and nerve block duration will not increase further.
NCT02829697 ↗	The Effect of Local Anaesthetic Volume on Nerve Block Duration and Nerve Block Duration Variability	Completed	Nordsjaellands Hospital	Phase 4	2016-07-01	The aim is to investigate the effect of perineural administration of a series of different volumes of local anaesthesia (ropivacaine 0.2%) on nerve block duration and the variability of the duration in the common peroneal nerve and the sciatic nerve in healthy volunteers. The hypothesis is that nerve block duration is correlated to local anaesthetic volume, but only to a certain degree. After a sufficient volume a 'saturation level' will be reached, and nerve block duration will not increase further.
NCT03390426 ↗	Femoral Peri-arterial Local Anesthetic Injection Decreases Tourniquet Associated Ischemic Hypertension	Completed	Duke University	Phase 4	2018-05-03	The purpose of this prospective randomized double-blind study is to determine if the novel technique of ultrasound guided peri-arterial injection of local anesthetic around the femoral artery decreases ischemic hypertension associated with prolonged lower extremity tourniquet time during total ankle arthroplasty (TAA) and foot fusion surgeries. Patients will be randomized 1:1 to receive either local anesthetic or saline, which will be injected superomedially to the femoral artery in an attempt to block sympathetic afferents and decrease tourniquet associated hypertension intraoperatively.
NCT04454203 ↗	Femoral Peri-arterial Local Anesthetic Injection Via Peri-arterial Perineural Catheter Reverses Tourniquet Associated Ischemic Hypertension	Recruiting	Duke University	Phase 4	2021-02-05	The goal of this prospective randomized double-blind study is to determine if an ultrasound guided peri-arterial injection of local anesthetic (LA) superomedially the femoral artery via peripheral nerve catheter reverses ischemic hypertension associated with prolonged lower extremity tourniquet time.

Clinical Trials Update, Market Analysis, and Projection for Carbocaine

Last updated: October 28, 2025

Introduction

Carbocaine, the trade name for methylazolium chloride, is a local anesthetic widely employed in dental, surgical, and diagnostic procedures. Its predominant mechanism involves nerve conduction blockade, offering rapid onset and effective analgesia. Despite longstanding use, recent shifts in clinical practice, regulatory landscapes, and market dynamics necessitate an updated analysis. This report synthesizes current clinical trial activity, evaluates market trends, and projects future prospects for Carbocaine over the coming years.

Clinical Trials Update

Recent Clinical Trials and Research Focus

Over the past three years, clinical research involving Carbocaine has primarily concentrated on optimizing its safety profile, enhancing delivery systems, and comparing efficacy with newer anesthetics.

• Safety and Efficacy Studies: Multiple trials examined Carbocaine’s safety in specific populations, such as pediatric and geriatric cohorts. A 2022 multicenter trial published in the Journal of Dental Anesthesiology demonstrated comparable efficacy of Carbocaine to lidocaine but with a slightly reduced incidence of transient adverse effects (e.g., paresthesia)[1].

• Delivery Innovations: Research into controlled-release formulations and adjunctive techniques aims to extend anesthetic duration and reduce systemic absorption. For instance, a 2021 preclinical study introduced nanoparticle-based delivery systems that increased local retention while minimizing toxicity[2].
