1. Why am I using Rocuronium Bromide Medsurge?

Rocuronium Bromide Medsurge contains the active ingredient rocuronium bromide. Rocuronium Bromide is one of a group of medicines called muscle relaxants.
Rocuronium Bromide is used during an operation as part of the general anaesthetic. When you have an operation, your muscles must be completely relaxed. This makes it easier for the surgeon to perform the operation.

Do not use if you have ever had an allergic reaction to rocuronium bromide or any of the ingredients listed at the end of the CMI.

4 Clinical Particulars

4.9 Overdose

The symptoms of overdosage with a non-depolarising muscle relaxant are those of prolonged paralysis, apnoea, low tidal volume, respiratory depression and/or persistent muscle weakness. In animal studies, severe depression of cardiovascular function ultimately leading to cardiac collapse did not occur until a cumulative dose of 750 x ED₉₀ (135 mg.kg^-1 rocuronium bromide) was administered.
In the event of overdosage and prolonged neuromuscular block, the patient should continue to receive ventilatory support and sedation. In this situation there are two options for the reversal of neuromuscular block: (1) Sugammadex can be used for reversal of intense (profound) and deep block. The dose of sugammadex to be administered depends on the level of neuromuscular block. (2) An acetylcholinesterase inhibitor (e.g. neostigmine, edrophonium, pyridostigmine), with appropriate vagolytic (e.g atropine) can be used at reappearance of T₂ or at the first signs of clinical recovery and should be administered in adequate doses. If administration of an acetylcholinesterase inhibiting agent fails to reverse the effects of rocuronium, ventilation must be continued until spontaneous breathing is restored.
Use of a reversal agent should not begin until definite signs of spontaneous recovery are present. Overdosage of an acetylcholinesterase inhibitor can be dangerous.

6.7 Physicochemical Properties

1-(17β-Acetoxy-3α-hydroxy- 2β-morpholino-5α-androstan-16β-yl)-1-allylpyrrolidinium bromide; C₃₂H₅₃BrN₂O₄.
Rocuronium bromide is a quaternary aminosteroid and an analogue of vecuronium bromide. It is an off-white to pale yellow or slightly pink amorphous powder which is readily soluble in water (> 200 mg/mL). A 1% w/v solution in water has a pH of 8.9-9.5. In aqueous solution rocuronium bromide is more stable at acidic pH.
