title: Increased tolerance to vecuronium in a patient with testicular feminization.
abstract: Muscle relaxant pharmacophysiology can be altered in various clinical situations. We report increased requirement of vecuronium in a patient diagnosed with testicular feminization. Increased level of endogenous testosterone and steroidal-core structure of vecuronium may explain the increased tolerance to vecuronium in this patient.
