Gantacurium Chloride is a new, investigational, non-depolarizing ultra-short acting neuromuscular blocker. It is being developed by Avera Pharmaceuticals. Gantacurium chloride is an ultra-short-acting, non-depolarising neuromuscular blocker that was jointly discovered by GlaxoSmithKline and the Wiell Medical. 22 Mar New Drug Developments for Neuromuscular Blockade and Reversal: Gantacurium, CW, CW, and Calabadion.

The singular distinguishing clinical feature of gantacurium from any other non-depolarizing neuromuscular blocking drug clinically tested is that it has the desired duality of a rapid onset and an ultrashort duration of action even when administered at 3—4 times the ED 95 doses.
The lack of availability of a compound with these characteristics and an increasing awareness of the adverse effects or residual NMB 2729 has led to the identification of a new series of fumarate compounds, olefinic double-bonded isoquinolinium diesters, as neuromuscular blockers.
Gantacurium chloride formerly recognized as GWA and as AVA is a new experimental neuromuscular blocking drug or skeletal muscle relaxant in the category of non-depolarizing neuromuscular-blocking drugsused adjunctively in surgical anesthesia to facilitate endotracheal intubation and to provide skeletal muscle relaxation during surgery or mechanical ventilation. The neuromuscular blocking effect of Org Residual neuromuscular blockade and critical respiratory events in the postanesthesia care unit.
Acta Anaesthesiol Scand Suppl. Unlike the pH- and temperature-dependent chemodegradation seen with atracurium and cisatracurium, the inactivation of gantacurium via cysteine adduct formation is independent of body pH and temperature. Effect of d -tubocurarine pretreatment on succinylcholine twitch augmentation and neuromuscular blockade. Muscle relaxants Quaternary ammonium compounds Tetrahydroisoquinolines Phenol ethers Organochlorides Chlorides.
The two neuromuscular blocking agents studied in human volunteers to date have a rapid onset of effect and a predictable duration of action that is either ultra-short gantacurium or intermediate CW and is shortened in animals by the administration of exogenous cysteine.
The New York Times.
Gantacurium is not yet available for widespread clinical use: Hemodynamic effects and onset time of increasing doses of vecuronium in patients undergoing myocardial revascularization. Can Anaesth Soc J. Indeed, the idea of exploring asymmetric tetrahydroisoquinolinium esters had already been seeded with parallel and earlier syntheses of another series of asymmetric potential neuromuscular blocking agents,  although the original concept for asymmetricity in the design of new neuromuscular blocking drugs dates back to  with reported combinations of the respective halves of laudexium and succinylcholine suxamethonium modeled, presumably, on the asymmetric structure of the prototypical neuromuscular blocking agent d – tubocurarine gantadurium made its entry into anesthetic practice on 23 Januaryat the Montreal Homeopathic Hospital.
Bronchospasm induced gantacurijm althesin and pancuronium bromide”. Gantacurium and CW do not potentiate muscarinic receptor-mediated airway smooth muscle constriction in guinea pigs. This accounts for the decreased frequency of postoperative residual gantaacurium after administration of intermediate-acting agents.

A short duration of action of a neuromuscular blocking agent allows flexibility in terms of intraoperative use. It exists as the l – and d -enantiomers. Development and potential clinical impact of ultra-short acting neuromuscular blocking agents C. Doubling the dose from one to two gantacyrium the ED 95 shortens the onset by 2. A Neuronal acetylcholine receptor subunit alpha Developing a non-depolarizing neuromuscular blocking agent that, like succinylcholine, has a rapid onset and a short duration of effect remains a goal of ongoing research.
Supplemental Content Full text links. The clinical arena of neuromuscular blocking agents is a minefield of jargonistic gantacuirum, and some definitions below help to clarify:. The onset of vecuronium is shortened from 3. Whether or not to administer an anticholinesterase to all patients who receive a neuromuscular blocking agent is an area of disagreement among clinicians.
The risk or severity of adverse effects can be increased when Gantacurium Chloride is combined with 2,5-Dimethoxyethylthioamphetamine. Bis- and mixed-tetrahydroisoquinolinium chlorofumarates: Preparation of dimeric isoquinolines as ultra short acting neuromuscular blockers.
New non-depolarizing neuromuscular blocking agents. Like sugammadex reversal of rocuronium, CW can be reversed at any time fantacurium cysteine injection.
Gantacurium chloride administered to anesthetized and ventilated healthy volunteers, caused dose dependent transient decrease in arterial blood pressure, mild histamine release at higher doses and no consistent changes in pulmonary compliance. There was complete failure gantacugium disseminate the true picture that these effects were not only transient but that the extent of the hypotensive effect and the reflex tachycardia were rarely of clinical significance and therefore did not require adjunctive therapy, as evidenced by the complete lack of any clinical literature advocating the need for adjunctive gantackrium use concomitantly with the administration of tetrahydroisoquinolinium neuromuscular blocking agents.
The short duration of action of gantacurium is consistent with that of other neuromuscular blocking compounds that are extensively metabolized.
For vecuronium, increasing the dose from 0. More commonly, neuromuscular blocking agents that are more extensively metabolized or broken down have a shorter duration gantacurijm action.
Gantacurium Chloride – DrugBank
It contains six chiral centres. Residual paralysis in the PACU after a single intubating dose of nondepolarizing muscle relaxant with an intermediate duration of action. The most common misinformation seeded gantzcurium the minds of anesthesiologists was the failure to categorically state that the cardiovascular effects following histamine release were transient: Sugammadex is a selective relaxant-binding agent, developed specifically to facilitate the reversal of NMB induced by agents with a steroidal structure.
Drug Interaction 1,Phenanthroline The therapeutic efficacy of Gantacurium Chloride can be decreased when used in combination with 1,Phenanthroline. Determination of recovery to a train-of-four ratio of 0. Its onset can be shortened to 2 min by increasing the dose to eight times its ED 95 Fig. More profound levels gabtacurium block can be maintained throughout in order to facilitate the surgical procedure or, NMB can be maintained later in the procedure as spontaneous recovery occurs more quickly with these agents and the incidence of inadequate recovery of neuromuscular function should be decreased.
Add to My Bibliography. Intraoperative acceleromyographic monitoring reduces the risk of residual neuromuscular blockade and adverse respiratory events in the postanesthesia care unit.
Its lack of potency and rapid clearance, however, were sought in new non-depolarizing blockers. Certainly, antagonism of a train-of-four ratio of 0. Middle East J Anesthesiol. For example, atracurium and cisatracurium—intermediated-acting compounds—are primarily inactivated non-enzymatically through one of two pathways, ester hydrolysis and Hofmann elimination, to compounds that have no neuromuscular blocking activity.
