- cyclophosphamide
Interactions between your drugs
cycloPHOSphamide succinylcholine
Applies to: cyclophosphamide, Anectine (succinylcholine)
GENERALLY AVOID: Cyclophosphamide may increase the effects of succinylcholine. The mechanism is irreversible inhibition of plasma cholinesterase resulting in decreased metabolism of some neuromuscular blockers. Apnea has been associated with this drug combination. Reductions in cholinesterase levels of 35% to 70% have been reported. This effect may last for up to several weeks after administration of cyclophosphamide.
MANAGEMENT: Succinylcholine should probably be avoided in patients with low cholinesterase levels. Other patients should be closely monitored for excessive and prolonged neuromuscular blockade and ventilatory support should be available.
