Problem
6.5
An analgesic research
study claims that a clinical trial shows that Drug S enhances
opioid analgesia in a potentially useful manner. Figure
6.5 shows the level of pain relief produced in postoperative
patients by single oral doses of placebo; Drug S, 10 mg;
morphine, 30 mg; and the combination of morphine, 30 mg,
and Drug S, 10 mg. The combination produced significantly
more analgesia than morphine, 30 mg, alone. Sedation, the
main side effect of all active treatments, was significantly
greater in the combination group than in the morphine group.
Question
6.5
Does this data suggest that
Drug S will be a useful additive to morphine?
 Yes
 No
 Cannot
say without more data (Specify what data.)
