Based on this reported activity, they should not be given concomitantly with Colistimethate for Injection, USP except with the greatest caution. Curariform muscle relaxants (e.g., tubocurarine) and other drugs, including ether, succinylcholine, gallamine, decamethonium and sodium citrate, potentiate the neuromuscular blocking effect and should be used with extreme caution in patients being treated with Colistimethate for Injection, USP.
