  • Factors That Affect the Onset of Action of Non-Depolarizing Neuromuscular
    Review Article pISSN 2005-6419 • eISSN 2005-7563 KJA Factors that affect the onset Korean Journal of Anesthesiology of action of non-depolarizing neuromuscular blocking agents Yong Byum Kim1, Tae-Yun Sung2, and Hong Seuk Yang3 Department of Anesthesiology and Pain Medicine, 1Gil Medical Center, Gachon University College of Medicine, Incheon, 2Konyang University Hospital, Konyang University College of Medicine, Daejeon, 3Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea Neuromuscular blockade plays an important role in the safe management of patient airways, surgical field improvement, and respiratory care. Rapid-sequence induction of anesthesia is indispensable to emergency surgery and obstetric an- esthesia, and its purpose is to obtain a stable airway, adequate depth of anesthesia, and appropriate respiration within a short period of time without causing irritation or damage to the patient. There has been a continued search for new neu- romuscular blocking drugs (NMBDs) with a rapid onset of action. Factors that affect the onset time include the potency of the NMBDs, the rate of NMBDs reaching the effect site, the onset time by dose control, metabolism and elimination of NMBDs, buffered diffusion to the effect site, nicotinic acetylcholine receptor subunit affinity, drugs that affect acetylcho- line (ACh) production and release at the neuromuscular junction, drugs that inhibit plasma cholinesterase, presynaptic receptors responsible for ACh release at the neuromuscular junction, anesthetics or drugs that affect muscle contractil- ity, site and methods for monitoring neuromuscular function, individual variability, and coexisting disease. NMBDs with rapid onset without major adverse events are expected in the next few years, and the development of lower potency NMBDs will continue.

  • RAPLON (Rapacuronium Bromide) for Injection, Administered at 25% Recovery of Control T1
    ™ RAPLON (rapacuronium bromide) for Injection Organon Inc. West Orange, NJ 07052 5310167 8/99 14 ReferenceRevision ID: 12867722 1 THIS DRUG SHOULD BE ADMINISTERED BY ADEQUATELY-TRAINED INDIVIDUALS FAMILIAR WITH ITS ACTIONS, CHARACTERISTICS AND HAZARDS. DESCRIPTION RAPLON™ (rapacuronium bromide) for Injection is a nondepolarizing neuromuscular blocking agent. Its chemical name is 1-[(2β,3α,5α,16β,17β)-3-(Acetyloxy)-17-(1-oxopropoxy)-2-(1­ piperidinyl)androstan-16-yl]-1-(2-propenyl) piperidinium bromide. The chemical formula of the bromide salt is C37H61BrN2O4 with a molecular weight of 677.78. The structural formula is: O O N+ H N H H O H – O Br ReferenceRevision ID: 12867722 2 RAPLON™ is a synthetic steroid molecule with a mono-quaternary structure in the form of a bromide salt. This chemical structure has a basic steroid framework similar to other neuromuscular blocking agents like vecuronium, pancuronium, rocuronium, and pipecuronium. Rapacuronium bromide is distinguished as being a propenyl bromide ammonium salt with a 17-hydroxy propionate carboxyester that has the same basic steroid backbone as the rest of the family of steroid neuromuscular blockers. RAPLON™ is supplied as a sterile, nonpyrogenic lyophilized cake in 5 mL and 10 mL vials. Each 5 mL vial contains 100 mg of rapacuronium bromide base, 35.8 mg of citric acid anhydrous, 7.5 mg of sodium phosphate dibasic anhydrous, 137.5 mg of mannitol, and sodium hydroxide and/or phosphoric acid to buffer and adjust the pH. When the 5 mL vial is reconstituted to a volume of 5 mL with sterile water for injection or bacteriostatic water for injection, an isotonic preparation for intravenous injection is obtained at a pH of 4.0 with a concentration of 20 mg of rapacuronium bromide base per mL.

  • Chapter 13 – Pharmacology of Muscle Relaxants and Their Antagonists Mohamed Naguib, Cynthia A
    Chapter 13 – Pharmacology of Muscle Relaxants and Their Antagonists Mohamed Naguib, Cynthia A. Lien HISTORY AND CLINICAL USE In 1942 Griffith and Johnson[1] suggested that d-tubocurarine (dTc) is a safe drug to use during surgery to provide skeletal muscle relaxation. One year later, Cullen[2] described its use in 131 patients who had received general anesthesia for their surgery. In 1954, Beecher and Todd[3] reported a sixfold increase in mortality in patients receiving dTc versus those who had not received a relaxant. The increased mortality was due to a general lack of understanding of the pharmacology of neuromuscular blockers and their antagonism. The impact of residual neuromuscular blockade postoperatively was not appreciated, guidelines for monitoring muscle strength had not been established, and the importance of pharmacologically antagonizing residual blockade was not understood. Since then, the understanding of neuromuscular blocker pharmacology has improved, and relaxants have become an important component of many anesthetics and have facilitated the growth of surgery into new areas with the use of innovative techniques.[4] Succinylcholine, introduced by Thesleff[5] and by Foldes and colleagues in 1952,[4] changed anesthetic practice drastically. Its rapid onset of effect and ultrashort duration of action allowed for rapid tracheal intubation. In 1967, Baird and Reid first reported on clinical administration of the synthetic aminosteroid pancuronium.[6] Though similar to dTc, in terms of its duration of action, this compound had an improved cardiovascular side effect profile. It lacked ganglionic-blocking and histamine-releasing properties and was mildly vagolytic. The resulting increases in heart rate and blood pressure were considered significant improvements over its predecessors.
