Risk of Major Adverse Cardiovascular Events for Naldemedine & Other Medications for Opioid Induced Constipation

This is a prevalent new user cohort study conducted using multiple databases linkable to medical records and the National Death Index (NDI) to assess MACE risk among adult patients with chronic non-cancer pain receiving naldemedine or a comparator OIC medication. The uptake of naldemedine and comparator OIC medications will be monitored for each database annually until a sufficient number of patients to support the comparative analyses in the safety assessment phase is accrued. The safety assessment phase will commence at the conclusion of the monitoring phase.
