All Clinical Trials for NEOSTIGMINE METHYLSULFATE

Trial ID Title Status Sponsor Phase Start Date Summary
NCT01050543 ↗ Comparison of Sugammadex With Neostigmine as Reversal Agents for Rocuronium at Reappearance of T2 (Study P06101) Completed Merck Sharp & Dohme Corp. Phase 3 2010-02-01 This is a randomized, active-controlled, parallel-group, single-dose, multi-site, safety-assessor blinded study comparing sugammadex to neostigmine for reversal of neuromuscular blockade in Korean subjects undergoing elective surgical procedures under general anesthesia that require rocuronium for neuromuscular blockade. Study medication will be administered at reappearance of T2. Time to recovery will be measured from start of study medication administration to recovery of the T4/T1 ratio of 0.9. The primary hypothesis is that the time to recovery of the T4/T1 ratio of 0.9 is shorter with sugammadex than with neostigmine.
NCT02279147 ↗ Cholinergic Anti-inflammatory Pathway in Prevention & Treatment of the SIRS in Patients With Jaundice After Operation. Unknown status Wanqing Gu Phase 1/Phase 2 2014-08-01 RATIONALE:Anticholinesterase drugs and cholinergic M receptor antagonist are applied to patients who have obstructive jaundice after operation. PURPOSE:This clinical trial was designed to lower the incidence and mortality of operation complications in patients with obstructive jaundice .
NCT02370433 ↗ Use of Prokinetics During Inpatient Bowel Care for SCI Patients Unknown status James J. Peters Veterans Affairs Medical Center Phase 1 2012-12-01 Bowel care (BC) is a time-consuming and cumbersome activity of daily living for most individuals with SCI. Previous studies have reported that the average time to complete a BC routine is 45 minutes; 10-20% of SCI individuals report BC routines lasting for more than 1 hour. In past studies, the investigators have shown that a medication called neostigmine can increase bowel activity and thus, promote bowel movement. The investigators have successfully used this medication with traditional and novel methods of colonoscopic preparations, and have shown that it improves the quality of these preparations. In this study, we would like to test the applicability of this medication to bowel care routines. The investigators believe that the addition of this medication to the beginning of regular bowel regiments will significantly decrease the time and effort needed to complete BC, thus improving patient perception of their BC routines and quality of life. SCI individuals followed by the James J Peters VA Medical Center (JJPVAMC) SCI Medical Service are admitted on a routine basis for inpatient respite care, therapy, and/or annual physicals. Such inpatient stays typically range in duration from 1 week to 3 weeks, during which the patient undergo BC routines assisted by the inpatient care team. BC routines are typically performed every other day, or thrice weekly (Monday, Wednesday, Friday) in "Blue Rooms" located on the inpatient SCI wards (IE and ID). The bowel care routine, including duration of procedure, use of assistive medications or devices, and completeness of bowel care are documented in the patients' electronic medical chart (CPRS) by care providers. The investigators propose to perform the described protocol in individuals who have been admitted to the hospital for routine care and are otherwise healthy. In doing so, the investigators can ensure that patients are vigilantly monitored during each BC session, and that any changes in BC pattern are accurately observed and documented. Furthermore, by performing these procedures on an inpatient basis, study investigators can ensure the consistency of care and daily routine, allowing for better control of study conditions.
NCT03299452 ↗ Clinical Studies by Using Alphacait to Screen Drugs for Advanced Solid Tumor Unknown status Alphacait, LLC Phase 2 2017-01-01 This is a single-center, open-label, single-arm, non-randomized study designed to evaluate PFS, safety, overall survival (OS), objective response rate (OPR), disease control rate (DCR) and biomarkers of cancer therapy based on Alphacait screening system in subjects with advanced malignant tumor.
NCT03299452 ↗ Clinical Studies by Using Alphacait to Screen Drugs for Advanced Solid Tumor Unknown status Haining Health-Coming Biotech Co., Ltd. Phase 2 2017-01-01 This is a single-center, open-label, single-arm, non-randomized study designed to evaluate PFS, safety, overall survival (OS), objective response rate (OPR), disease control rate (DCR) and biomarkers of cancer therapy based on Alphacait screening system in subjects with advanced malignant tumor.
NCT03316963 ↗ Neostigmine For Snoring During DISE Terminated Emory University Early Phase 1 2017-11-14 The study team is seeking a novel treatment for snoring involving local application of a nerve stimulant medication, neostigmine. In this study, neostigmine will be injected into 5 sites of the soft palate during a standard procedure, drug-induced sleep endoscopy, to evaluate the effect on snoring.
NCT03587441 ↗ Intrathecal Neostigmine for Prevention of PDPH Completed Fayoum University Hospital Phase 4 2018-08-04 Neuraxial blocks continue to be the cornerstone of anesthesia and postoperative analgesia for normal vaginal delivery and elective caesarean section due to its approved safety and efficiency for decades. Post-dural puncture headache (PDPH) is still one of the most common complications of neuraxial anesthetic techniques. The headache could be severe and limit the activities of the new mother to care for her baby, prolong hospital stay. PDPH is defined as a headache that develops within five days of dural puncture and can't be attributed to any other types of headache and mostly is postural in character. Neostigmine methylsulfate is a synthetic carbamic acid ester which reversibly inhibits the enzyme Acetylcholine esterase (AChE) that makes more Acetylcholine molecules available at cholinergic receptors. Neostigmine is used in anesthesia mainly as a reversal for non-depolarizing neuromuscular agents. Intrathecal (IT) neostigmine was tried as an adjuvant to local anesthetics in IT block for elective cesarean sections to decrease local anesthetic consumption and to prolong postoperative analgesia. Side effects of IT neostigmine are dose-dependent with doses more than 25 µg especially nausea and vomiting and could be decreased by increasing the baricities of the local anesthetic solutions and by early head up position after IT injection. However, its effect on PDPH was not investigated before in literature. Parturients will be randomly assigned into one of two groups: the intervention group will receive 20 µg with IT Bupivacaine and the control group will receive an equivalent volume of dextrose 5% with the IT Bupivacaine. The objective of the current study is to evaluate the efficacy and safety of IT neostigmine as an adjuvant to bupivacaine in reducing the incidence and severity of post-dural puncture headache in parturients scheduled for an elective cesarean section.
