Safety and Efficacy of Methoxyflurane for Treatment of Incident Pain
A Phase IV, Randomized, Double Blind, Single Centre, Placebo Controlled Study to Assess the Safety and Efficacy of Methoxyflurane [Penthrox] for the Treatment of Incident Pain in Participants Undergoing a Bone Marrow Biopsy Procedure
This study aims to provide further supportive evidence that Methoxyflurane, a potent analgesic, administered using the Penthrox Inhaler is safe and efficacious in adult participants, specifically those who experience incident pain associated with a planned bone marrow biopsy.
