Published Studies Related to Codrix (Acetaminophen / Codeine)
Analgesic efficacy of rofecoxib compared with codeine/acetaminophen using a model of acute dental pain. [2005.10]
OBJECTIVE: To determine analgesic efficacy of a single oral dose of rofecoxib 50 mg compared with acetaminophen/codeine 600/60 mg, we conducted a double-blind, randomized, placebo- and active-comparator-controlled, parallel-group study... CONCLUSION: Rofecoxib provided superior analgesic efficacy compared with codeine/acetaminophen with fewer gastrointestinal and nervous system adverse events.
A randomized, double-blind, parallel-group study comparing the analgesic effect of etoricoxib to placebo, naproxen sodium, and acetaminophen with codeine using the dental impaction pain model. [2004.05]
OBJECTIVE: To compare the overall analgesic effect, including time to onset, peak and duration of effect for etoricoxib 120 mg, a new COX-2 selective inhibitor, in patients with acute pain to that of placebo. Naproxen sodium 550 mg and acetaminophen/codeine 600/60 mg were the active comparators.Etoricoxib was generally well tolerated.
Tramadol suppositories are less suitable for post-operative pain relief than rectal acetaminophen/codeine. [1999.07]

The analgesic efficacy of flurbiprofen compared to acetaminophen with codeine. 
In a single-dose, parallel group, randomized block treatment allocation study, the relative analgesic efficacy of flurbiprofen, a nonsteroidal antiinflammatory drug, was compared to acetaminophen 650 mg with codeine 60 mg, zomepirac sodium 100 mg, and placebo... The results of this study support previous work on flurbiprofen.
Comparison of ibuprofen and acetaminophen with codeine following cosmetic facial surgery. [2009.10]
OBJECTIVES: To compare the efficacy and side effects of ibuprofen and acetaminophen with codeine when given postoperatively following cosmetic facial surgery and to assess whether bruising is worse or the incidence of hematoma is greater when ibuprofen is taken postoperatively. DESIGN: Prospective, double-blind, randomized trial. SETTING: Accredited outpatient surgery centre... CONCLUSIONS: Ibuprofen 400 mg is as effective as acetaminophen/codeine 600/60 mg for pain relief following cosmetic facial surgery. Ibuprofen is better tolerated, with fewer side effects, than acetaminophen with codeine. Ibuprofen given postoperatively does not result in increased bruising or increased incidence of hematoma.

SB-705498 Dental Pain Study After Tooth Extraction
This clinical trial is a multi centre, randomised, single-blind, parallel group,
placebo-controlled, single oral dose study with a positive control arm. Patients previously
scheduled for 3rd molar tooth extraction, who are otherwise healthy, will be recruited. Upon
completion of surgery, e. g. prior to established pain, patients will be randomised to
treatment (SB-706598, placebo or co-codamol) and dosed with the study medication
Rofecoxib to Prevent Pain After Third Molar (Wisdom Tooth) Extraction [Completed]
This study will evaluate the ability of a new non-steroidal anti-inflammatory drug (NSAID)
called rofecoxib to prevent pain following third molar (wisdom tooth) extraction. The Food
and Drug Administration approved rofecoxib in 1999 to treat the symptoms of arthritis,
menstrual cramps, and pain.
Healthy normal volunteers between 16 and 35 years of age in general good health who require
third molar (wisdom tooth) extraction may be eligible for this study. Candidates will be
screened with a medical history and oral examination, including dental x-rays as needed to
confirm the need for third molar removal.
Participants will have all four wisdom teeth extracted, and a biopsy (removal of a small
piece of tissue) will be taken from the inside of the cheek around the area behind the lower
wisdom tooth. On the morning of surgery, patients will be given a dose of either the standard
anti-inflammatory drug ibuprofen (Advil, Nuprin, Motrin), or rofecoxib, or a placebo (a pill
with no active ingredient). Before surgery, they will be given a local anesthetic (lidocaine)
in the mouth and a sedative (midazolam) through an arm vein.
After the surgery, patients will remain in the clinic for up to 4 hours to monitor pain and
the effects of the drug. Patients will complete pain questionnaires. Patients whose pain is
unrelieved an hour after surgery may request and receive morphine intravenously (through a
vein). After 4 hours, patients will be discharged with additional pain medicines (Tylenol
with codeine and the study drug) and instructions for their use. They will also be given a
pain diary to record pain ratings and medications taken at home. A clinic staff member will
telephone patients at home the morning after surgery to ensure they are rating their pain
intensity at the proper time and are taking their medications as instructed.
Patients will return to the clinic 48 hours after surgery with the pain diary and pain
relievers. At this visit, another biopsy will be taken under local anesthetic.
