Background: Calabadion 2 is a new drug-encapsulating agent. In this study, the authors aim to assess its utility as an agent to reverse general anesthesia with etomidate and ketamine and facilitate recovery.
Methods: To evaluate the effect of calabadion 2 on anesthesia recovery, the authors studied the response of rats to calabadion 2 after continuous and bolus intravenous etomidate or ketamine and bolus intramuscular ketamine administration.
Introduction: Acetylcholinesterase inhibitors (neostigmine, edrophonium) and encapsulating agents (sugammadex and calabadion) can be used to reverse residual neuromuscular blockade (NMB).
Areas Covered: This review provides information about efficacy, effectiveness, and side effects of drugs (acetylcholinesterase inhibitors and encapsulating agents) used to reverse neuromuscular blocking agents (NMBAs).
Expert Opinion: The therapeutic range of acetylcholinesterase-inhibitors is narrow and effectiveness studies demonstrate clinicians don't use these unspecific reversal agents effectively to increase postoperative respiratory safety.
Background: The authors evaluated the comparative effectiveness of calabadion 2 to reverse non-depolarizing neuromuscular-blocking agents (NMBAs) by binding and inactivation.
Methods: The dose-response relationship of drugs to reverse vecuronium-, rocuronium-, and cisatracurium-induced neuromuscular block (NMB) was evaluated in vitro (competition binding assays and urine analysis), ex vivo (n = 34; phrenic nerve hemidiaphragm preparation), and in vivo (n = 108; quadriceps femoris muscle of the rat). Cumulative dose-response curves of calabadions, neostigmine, or sugammadex were created ex vivo at a steady-state deep NMB.
