Outcome Measures
Primary Outcome Measures
- Usage of Morphine, Post Surgery [0 hour to 24 hours after IP administration]
Change in the amount of morphine use (in milligrams) by subjects in each treatment group for a 24 hour period post IP administration.
Secondary Outcome Measures
- Usage of Morphine, Post Surgery at other intervals [0 hour to 48 hours after IP administration]
Change in the amount of morphine use (in milligrams) by subjects in each treatment group for 0-48 hours after IP administration.
- Pain intensity assessed using an 11-point NRS ranging [Baseline till 48 hours post IP administration]
11-point NPRS ranging from a score of 0 to 10.
- Pain relief assessed using an 5-point likert scale [Baseline till 48 hours post IP administration]
5-point likert scale from a score of 0 to 4.
- Time to First Dose of Rescue Analgesia [0 hour to 48 hours after IP administration]
Time to first rescue was calculated as the elapsed time from administration of Dose 1 to the administration of the first dose of rescue analgesia.
- Frequency of Doses of Rescue Analgesia Utilized Per Subject [0 hour to 48 hours after IP administration]
Rescue analgesia was available to subjects with inadequately controlled pain upon request.
- Proportion of subjects who received Rescue Analgesia [0 hour to 48 hours after IP administration]
Proportion of rescue was calculated as the elapsed time from administration of Dose 1 to the administration of the first dose of rescue analgesia.
- Patient Global Assessment (PGA) of Pain Control [0 hour to 48 hours after IP administration]
PGA of pain control was evaluated by subject reported degree of pain control according to a 5 point scale (0-4)
