Pentamorphone was developed as a highly potent opioid with rapid onset and short duration of action that has been reported to produce analgesia with limited depression of ventilation. Pentamorphone participated in a clinical trial for the management of postoperative pain. However, no acute cardiorespiratory changes were observed. The drug was ineffective for treating acute postoperative pain after major surgery. In addition, was shown that pentamorphone, 10 micrograms/kg, does not seem to offer any significant advantage over opioids currently used for anesthesia in patients undergoing elective coronary artery bypass grafting (CABG). That is why its further development was discontinued.
