Sugammadex

Bridion

Modified γ-cyclodextrin selective relaxant binding agent

Encapsulates rocuronium > vecuronium > pancuronium in 1:1 complex. No effect on cisatracurium, atracurium, sux.

Indications

  • Reversal of rocuronium / vecuronium NMB
  • Emergency reversal of failed RSI

Dosing

ContextAdultPediatric
Routine reversal (TOF 2+)2 mg/kg IV2 mg/kg IV (ages 2+)
Deep block (PTC ≥ 1, no TOF)4 mg/kg IV
Immediate emergency reversal16 mg/kg IV

Pharmacokinetics

Onset 1–3 min. Renally excreted; ESRD prolonged clearance (still effective).

Side effects

  • !Anaphylaxis (~1:2,500 to 1:20,000)
  • !Bradycardia/asystole (rare)
  • !Hormonal contraceptive interaction — counsel 7 days alternative contraception
  • !Coagulation prolongation (small ↑ in PT/aPTT, no clinical bleeding)

Contraindications

  • ×Known sugammadex allergy

Clinical pearls

  • Re-paralysis with roc/vec ineffective for 24 h post-sugammadex; use cis or non-aminosteroid.
  • ESRD: works fine; sugammadex-roc complex slowly excreted but no toxicity.
  • Quantitative TOF should still be confirmed even after 4 mg/kg deep dose.
