Study Arms:
- Placebo (Type: PLACEBO_COMPARATOR): This study arm will encompass the administration of a placebo (physically identical to Naproxen) orally to participants. Naproxen is a painkiller with intrinsic anti-inflammatory properties, while the placebo has no pharmacological properties associated with it. Participants will also be taking Pantoprazole to negate the gastrointestinal consequences of Naproxen (or the placebo). Participants will not know which arm of the study they belong to. In addition, they will attend scheduled check-ups where their vitals will be recorded, as well as laboratory indicators of gastrointestinal complications (creatinine levels, etc) for their safety.
- Naproxen (Type: EXPERIMENTAL): Intervention arm involves administering 500mg Naproxen twice a day to participants and 40mg of Pantoprazole once a day in tandem. Pantoprazole will negate gastrointestinal consequences of Naproxen and reduce the likelihood of a complication occurring. Participants will take Naproxen at the above dosage from the time of surgery to four weeks following surgery. They will attend scheduled check-ups where their vitals will be recorded, as well as laboratory indicators of gastrointestinal complications (creatinine levels, etc) for their safety. This experiment is double-blinded so neither investigators nor participants will know which arm of the study they belong to.

Based on this trial design, predict the completion outcome and termination type (if applicable).
