Study start date: September 1, 2010

Actual date on which the first participant was enrolled.

Using a retrospective database analysis, OA patients taking at least one CYP450-metabolized opioid (codeine, fentanyl, hydrocodone, methadone, oxycodone, or tramadol) and at least one other prescription drug metabolized via the CYP450 system were evaluated for an incident drug-drug exposure (DDE), which places them at risk for experiencing a pharmacokinetic drug-drug interaction (DDI).

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

10000 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Case-Control

These studies compare people who have a disease (cases) with those who don't (controls). The goal is to look back at previous exposures or risk factors to identify what might have contributed to the disease.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.
