<p>The following agents have been shown to influence the magnitude and/or duration of action of non-depolarizing neuromuscular blocking agents:</p>

<p>Effect of other agents on Rocuronium Bromide-</p>

<p><strong>Increased Effect</strong>: Halogenated volatile anesthetics potentiate the neuromuscular block of Rocuronium Bromide. The effect only becomes apparent with maintenance dosing. Reversal of the block with anti-cholinesterase inhibitors could also be inhibited. Long-term concomitant use of corticosteroids and Rocuronium Bromide in the ICU may result in prolonged duration of neuromuscular block or myopathy.<br />
<br />
Other drugs:&nbsp;</p>

<ul>
	<li>Antibiotics: aminoglycoside, lincosamide and polypeptide antibiotics, acylamino-penicillin antibiotics.&nbsp;</li>
	<li>Diuretics, quinidine and its isomer quinine, magnesium salts, calcium channel blocking agents, lithium salts, local anaesthetics (lidocaine i.v., bupivacaine epidural) and acute administration of phenytoin&nbsp;</li>
	<li>Recurarization has been reported after post-operative administration of: aminoglycoside, lincosamide, polypeptide and acylamino-penicillin antibiotics, quinidine, quinine and magnesium.</li>
</ul>

<p><strong>Decreased Effect</strong>: Prior chronic administration of phenytoin or carbamazepine. Protease inhibitors (gabexate, ulinastatin)&nbsp;<br />
<br />
<strong>Variable Effect</strong>: Administration of other non-depolarizing neuromuscular blocking agents in combination with Rocuronium Bromide may produce attenuation or potentiation of the neuromuscular block, depending on the order of administration and the neuromuscular blocking agent used. Suxamethonium given after the administration of Rocuronium Bromide may produce potentiation or attenuation of the neuromuscular blocking effect of Rocuronium Bromide.&nbsp;<br />
<br />
<strong>Effect of Rocuronium Bromide on other drugs</strong>: Rocuronium Bromide combined with lidocaine may result in a quicker onset of action of lidocaine.</p>
