Comparative Safety Analysis of Hydromorphone and Morphone Sulfate: Evidence from the 2004-2024 FAERS.
Article in Journal of pain research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Hydromorphone and morphine, as classic opioid drugs, are commonly used for postoperative analgesia and as adjuncts in the treatment of moderate to severe cancer pain and chronic pain. The lack of specific criteria and the complexity of their respective adverse events (AEs) make it difficult for clinical workers to make a decision. Methods: This study utilized the FAERS database to compare the baseline risk of AEs between hydromorphone and morphine sulfate. AEs of opioid drugs "morphine" and "hydromorphone" were extracted from FAERS from 2004 to 2024. Non-proportional signal mining is performed by calculating the ratio of reports (ROR), proportional reporting ratio, Bayesian confidence propagation neural network, and empirical Bayesian geometric mean. Then they were filtered and mapped to a total of 25 types of AEs, including primary preference term (PT) signals and systemic organ categories. Results: According to the FAERS database, Among totals of 44303 case reports related to two types of drug, 14902 reports were related to hydromorphone, 29401 reports were related to morphine sulfate. The statistical analysis results include 21890177 AEs reports in the FAERS database, of which 18282801 AEs reports are the "main analysis objects" of Hydromorphone and morphine. This study found that "psychological disorders" and "immune system disorders" are closely related to both drugs. But psychological disorders have the strongest correlation with Hydromorphone (ROR 6.33), while immune system disorders have the strongest correlation with morphine sulfate (ROR 8.41). The signal "General disorders and administrative site conditions" is more significantly associated with Hydromorphone. In addition, drug dependence is a common PT signal in both drugs, and prognosis should be closely monitored after treatment. Conclusion: Prescription decision-making should be a comprehensive and balanced process. Our study identified potential new and unexpected AEs for Hydromorphone and morphine, providing valuable evidence for the safety research of Hydromorphone and morphine. Especially for prescribers of hydromorphone, clinical vigilance should extend beyond its known opioid-class effects to particularly raise awareness of two unexpected adverse events: for the immune related disorders and administration site reactions.
