Levetiracetam

Levetiracetam (Keppra) is an oral and intravenous antiepileptic drug (AED) indicated as adjunctive therapy for partial onset seizures, myoclonic seizures, and generalized tonic-clonic (“grand mal”) seizures in adults. The medication is used in the...

Vecuronium

Vecuronium (Norcuron) is a nondepolarizing, aminosteroid neuromuscular junction blocker that, like rocuronium, works at the level of neuromuscular end plate’s nicotinic acetylcholine receptors (AChR) as a competitive antagonist. Because it competes with acetylcholine for...

Neostigmine

Neostigmine is a polar acetylcholinesterase inhibitor (does NOT cross the blood-brain barrier) that is routinely used to reverse non-depolarizing neuromuscular blocking agents (NMBA) like rocuronium, vecuronium, and cisatracurium. These NMBAs are competitive inhibitors at...

Cisatracurium

Cisatracurium (Nimbex) is a benzylisoquinolinium non-depolarizing neuromuscular blocking agent (NMBA) that works similar to rocuronium/vecuronium as a competitive nicotinic acetylcholine receptor (AChR) antagonist at the motor endplate. Although it has a slower onset of action...

Sugammadex

Sugammadex (Bridion) is an intravenous reversal agent for rocuronium and vecuronium, two aminosteroid, non-depolarizing neuromuscular junction blockers (NMJBs). It's a cyclodextrin molecule which encapsulates the NMJB within its core thereby preventing it from binding...

Rocuronium

Rocuronium is an aminosteroid nondepolarizing neuromuscular junction blocker (NMJB) I routinely use to facilitate tracheal intubation. The name rocuronium comes from the fact that it's a rapid onset -curonium (referring to its steroid structure). With a...

Succinylcholine

Neuromuscular blocking agents (NMBAs or "paralytics") are categorized as depolarizing (classically succinylcholine) and nondepolarizing. They're important drugs to know because we routinely use them in the operating room, intensive care unit, and during elective...
