Trial Type	Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
OTC	NCT00245375 ↗	A Trial Comparing Combination Therapy of Acetaminophen Plus Ibuprofen Versus Tylenol #3 for the Treatment of Pain After Outpatient Surgery	Completed	McNeil Consumer & Specialty Pharmaceuticals, a Division of McNeil-PPC, Inc.	N/A	2005-01-01	Increasingly in general surgery, the investigators are conducting outpatient day surgery. Ambulatory surgery currently comprises 60 to 70% of surgeries performed in North America. These patients all require some form of analgesia which can be taken at home in the first few days after the surgery. The current standard at the investigators' centre and many others in the maritime provinces is to provide a prescription for oral acetaminophen plus codeine or oxycodone (Tylenol #3®, Percocet ®). Some patients may receive more potent opioids such as oral hydromorphone (Dilaudid®). Unfortunately, the most commonly prescribed medication (Tylenol #3®) is often poorly tolerated by patients, has several undesirable side effects, and may not provide effective pain relief. In the investigators' experience, non-steroidal anti-inflammatory drugs (NSAIDs) are uncommonly a routine addition to the home analgesic regimen. Tylenol #3®, in the investigators' experience and opinion, is a poor post surgical pain medication. They hope to show that a combination of ibuprofen and acetaminophen is better for pain relief after these procedures. The combination of acetaminophen and ibuprofen would be a safe, cheap, and readily available regimen. Unfortunately, as the prescribing practices of surgeons are old habits, it will require a very convincing argument to get them to change their practices. A randomized controlled trial comparing these two regimens, the investigators hope, would be a powerful enough argument. The hypothesis of this study, therefore, is that the pain control provided by a combination of acetaminophen plus ibuprofen (650 mg/400 mg four times per day) will be superior to Tylenol #3® (600 mg acetaminophen/60 mg codeine/15 mg caffeine four times per day). This study will attempt to enroll 150 patients in total. Eligible patients will be identified by their attending surgeon and contacted by study personnel. Patients who enroll in the study will undergo their surgery in the usual manner. After the surgery, in the recovery room, once they are ready to go home, they will be randomized to receive combination A or B and be given a week's worth of pain medication. They will then go home and take this medication as directed. They will record their pain intensity and pain relief once per day using a diary provided in the study package. One week after their surgery, they will return to the hospital clinic and be seen by the study nurse. They will hand over the diary and any unused medication. They will also be asked several questions regarding their overall satisfaction, incidence of side effects, and how long until they were pain free. The risks of participating in this study are minimal from the risks inherent to the procedures and medications the patients would receive within the standard of care. Ibuprofen is a commonly used NSAID which is widely available over the counter and has an established safety profile. The most common adverse effects of ibuprofen and other NSAIDs are gastrointestinal bleeding and ulceration. Other less common adverse effects include nephrotoxicity, hypersensitivity reactions, hepatic dysfunction (longterm use), and cognitive dysfunction. The investigators' patients will be selected to exclude those most at risk for these complications (see exclusion criteria). Acetaminophen has few side effects, with no adverse effects on platelet function and no evidence of gastric irritation.

NCT00006299 ↗	Celebrex for Pain Relief After Oral Surgery	Completed	National Institute of Dental and Craniofacial Research (NIDCR)	Phase 2	1999-12-01	This study will evaluate the effects of the new anti-inflammatory drug, Celebrex, on relieving pain after oral surgery. It is also designed to assess the drug's selective inhibition of a chemical called cyclooxygenase-2 and not its closely related form, cyclooxygenase-1. This selective inhibition allows pain alleviation without the adverse side effects (e.g., bleeding and stomach upset) often associated with anti-inflammatory drugs. Healthy volunteers who require removal of their third molars are eligible for this study. Participants will have oral surgery for tooth extraction after receiving a local anesthetic (lidocaine) in the mouth and a sedative (midazolam) through an arm vein. On the evening before and 1 hour before surgery, patients will be given a dose of either the standard anti-inflammatory drug ibuprofen (Advil, Nuprin, Motrin), or Celebrex, or a placebo (a pill with no active ingredient). After surgery, a small piece of tubing will be placed in each extraction site and tied to an adjacent tooth to hold it in place. Samples will be collected from the tubing to measure chemicals involved in pain and inflammation. Patients will stay in the clinic for up to 6 hours after surgery while the anesthetic wears off and will complete pain questionnaires. During that time, they may receive acetaminophen plus codeine (Tylenol 3), if needed, for pain. The tubing then will be removed and the patient discharged with standard pain medication.
NCT00110474 ↗	Glucosamine Unum In Die [Once A Day] Efficacy (GUIDE) Trial: Glucosamine Sulfate in Patients With Knee Osteoarthritis	Completed	Rottapharm	Phase 3	2000-05-01	The primary objective of this study is to evaluate the efficacy and safety of glucosamine sulfate versus placebo on the symptoms of knee osteoarthritis after 6 months of treatment, using acetaminophen as a reference symptomatic medication.
NCT00129506 ↗	Comparing Methotrexate Followed by Misoprostol to Misoprostol Alone for Early Abortion	Completed	Ibis Reproductive Health	Phase 4	2005-05-01	Background: In most countries in which abortion is legal, medical abortions are induced with mifepristone and misoprostol. Since mifepristone is expensive and unavailable in many countries, it is important to find other regimens. Methotrexate, which is used with misoprostol in Canada, is also difficult to obtain in many countries. Misoprostol is inexpensive and available in almost all countries. A report from Nigeria found that 98% of 100 women aborted within 24 hours of using misoprostol given both sublingually and vaginally. Method: This will be a randomized controlled trial of the usual regimen used in Canada, methotrexate 50 mg/m2 intramuscularly (IM) followed three days later by 800 mcg vaginal misoprostol to the Nigerian regimen of 400 mcg sublingual misoprostol with 400 mcg vaginal misoprostol. The main outcome measure will be a completed abortion within the first week with secondary outcome measures including total surgery rate, time to abortion, complications, pain, side effects and patient satisfaction. Rationale: If the investigators can find an inexpensive, easily available, method of medical abortion, it will save many lives in third world countries.
