Sugammadex sodium

Description

To facilitate tracheal intubation, mechanical ventilation, and surgical access, NMB agents are frequently used as non-anesthetic adjuncts in surgical procedures. Sugammadex is able to function as a pharmacologic sink of rocuronium and vecuronium, another non-depolarizing neuromuscular blocker, without the cardiovascular adverse effects experienced with reversal agents that directly interact with the cholinergic system. The γ-cyclodextrin has been designed to enhance binding of the guest by incorporating acidic side chains to promote an electrostatic interaction with the positive nitrogen of the blocker. Starting with γ-cyclodextrin, these side chains are readily installed by first halogenating with iodine or bromine to provide a handle for nucleophilic displacement with either 3-mercaptopropionic acid in the presence of sodium hydride or with 3-mercaptopropionic acid methyl ester and cesium carbonate. The latter requires hydrolysis with sodium hydroxide to generate sugammadex sodium.

The Uses of Sugammadex sodium

Sugammadex Sodium is the first in a class of drugs called selective relaxant binding agents that offers improved termination of the paralytic effects of neuromuscular blocking agents and may have many potential peri-operative benefits.

Definition

ChEBI: Sugammadex sodium is an organic sodium salt that is the octasodium salt of sugammadex. Used for reversal of neuromuscular blockade induced by rocuronium and vecuronium in adults undergoing surgery. It has a role as a neuromuscular agent. It contains a sugammadex(8-).

What are the applications of Application

Sugammadex sodium is a modified γ-cyclodextrin. It is a selective relaxant binding agent (SRBA) indicated for reversal of neuromuscular block induced by steroid-based muscle relaxants, such as rocuronium bromide and vecuronium bromide. Sugammadex soium forms a complex with the muscle relaxants, and it reduces the amount of them available to bind to nicotinic cholinergic receptors in the neuromuscular junction.

Bridion

Side Effects

The most common adverse effects included coughing, movement, vomiting, dry mouth, dysgeusia, hypotension, parosmia, and a sensation of changed temperature.Sugammadex is recommended for the reversal of neuromuscular blockade induced by rocuronium or vecuronium; it should not be used with other steroidal blocking agents since safety and efficacy data are not available for these situations. It should also not be partnered with non-steroidal neuromuscular blockers such as succinylcholine or benzylisoquinolinium-based drugs. Since sugammadex is predominantly cleared by the kidneys, care should be taken when administering this reversal agent in patients with renal impairment.

Mode of action

Sugammadex Sodium is the sodium salt form of sugammadex, a biologically inert, selective relaxant binding agent (SRBA) composed of a modified, anionic gamma cyclodextrin derivative containing a hydrophilic exterior and a hydrophobic core, with neuromuscular blocking drug (NMBD) reversal activity. Upon administration, the negatively charged carboxyl-thio-ether groups of sugammadex selectively and reversibly bind to the positively charged quaternary nitrogen of a steroidal NMBD, such as rocuronium and vecuronium, which was administered at an earlier time for anesthetic purposes. The encapsulation of the NMBD by sugammadex blocks its ability to bind to nicotinic receptors in the neuromuscular junction and thereby reverses the NMBD-induced neuromuscular blockade.
