Neuromuscular blockade of fazadinium bromide (AH 8165) in renal failure patients.
Fazadinium bromide (AH 8165) is a new non-depolarizing neuromuscular blocking agent with rapid onset of action and intermediate duration of effect. The characteristics of the neuromuscular blockade induced were compared in normal and renal failure patients by monitoring the mechanical responses of thumb adductor muscle to ulnar nerve stimulation. The data suggest that renal failure, even in anephric patients, does not influence the depth of neuromuscular relaxation when judged from the identical dose-effect curves in both groups of patients. Moreover, the duration of the neuromuscular block was not significantly increased in end-stage kidney failure patients, whether the initial or late phases of the spontaneous recovery of neuromuscular transmission were considered, and this occurred over the entire therapeutic range. However, additional incremental injections of fazadinium bromide should be used cautiously, as evidence appeared of prolonged duration of action. This agent, fazadinium bromide, may therefore present useful advantages to other non-depolarizing neuromuscular blocking agents as to clinical safety and effects in patients with renal insufficiency.
