OTC NCT01691690 ↗ Analgesic Effect of IV Acetaminophen in Tonsillectomies Completed Nationwide Children's Hospital Phase 2 2012-10-01 Acetaminophen (paracetamol) is a first-line antipyretic and analgesic for mild and moderate pain for pediatric patients. Its common use (particularly in oral form) is underscored by its wide therapeutic window, safety profile, over the counter accessibility, lack of adverse systemic effects (as compared with NSAIDS and opioids) when given in appropriate doses. Although the exact anti-nociceptive mechanisms of acetaminophen continue to be elucidated, these mechanisms appear to be multi-factorial and include central inhibition of the cyclo-oxygenase (COX) enzyme leading to decreased production of prostaglandins from arachidonic acid, interference with serotonergic descending pain pathways, indirect activation of cannabinoid 1 (CB1) receptors and inhibition of nitric oxide pathways through N-methyl-D-aspartate (NMDA) or substance P. Of the above mechanisms, the most commonly known is that of central inhibition of COX enzymes by which the decreased production of prostaglandins diminish the release of excitatory transmitters of substance P and glutamate which are both involved in nociceptive transmission (Anderson, 2008; Smith, 2011). To date, several studies have shown acetaminophen's opioid sparing effect in the pediatric population when given by the rectal or intravenous routes (Korpela et al, 1999; Dashti et al, 2009; Hong et al, 2010).
New Formulation NCT01717157 ↗ A Study to Assess the Relative Bioavailability of 4 Formulations of Fentanyl Transdermal System Compared Against DUROGESIC Fentanyl Transdermal Patch After Single Application in Healthy Volunteers Completed Janssen Research & Development, LLC Phase 1 2012-08-01 The purpose of this study is to evaluate the pharmacokinetics and relative bioavailability of 4 new formulations of fentanyl transdermal patch in healthy participants after a single application for 72 hours.
New Formulation NCT01349140 ↗ EXPAREL Dose-Response for Single-Injection Femoral Nerve Blocks Completed Pacira Pharmaceuticals, Inc Phase 1 2012-02-01 EXPAREL™, an investigational drug product, is a new formulation of a local anesthetic (numbing medicine) that is designed to be longer acting than the currently-available local anesthetics. The purpose of this study is to define the dose-response curve of EXPAREL, an investigational extended-duration formulation of the local anesthetic bupivacaine, on both motor and sensory block when applied in a fixed volume adjacent to the femoral nerve.
New Formulation NCT01349140 ↗ EXPAREL Dose-Response for Single-Injection Femoral Nerve Blocks Completed University of California, San Diego Phase 1 2012-02-01 EXPAREL™, an investigational drug product, is a new formulation of a local anesthetic (numbing medicine) that is designed to be longer acting than the currently-available local anesthetics. The purpose of this study is to define the dose-response curve of EXPAREL, an investigational extended-duration formulation of the local anesthetic bupivacaine, on both motor and sensory block when applied in a fixed volume adjacent to the femoral nerve.
New Combination NCT00620828 ↗ The Role of Intra-Operative Intracapsular Blocks in Post-Operative Pain Management Following Total Knee Arthroplasty Completed Pfizer Phase 4 2007-05-01 The purpose of this study is to use a new combination of anesthesia techniques in an attempt to minimize early pain after surgery and improve the patient's ability to participate more fully with physical therapy. Total knee replacement patients who participate will receive the standard anesthesia. This includes a spinal nerve block as well as a femoral nerve block. The study is looking at the added benefits of including an injection of numbing medication (Bupivicaine) to the back of the knee. This injection occurs during surgery. In order to compare the outcomes we will also have a group of patients who will receive a saline injection as opposed to the numbing medication. Patients are randomly assigned to a group. Outcomes are measured up until twenty-four hours following the surgery.

NCT00027014 ↗ Herb-Opioid Interactions Completed National Center for Complementary and Integrative Health (NCCIH) Phase 4 2001-09-01 This is a series of studies in healthy volunteers to assess the potential for adverse interactions between St. John's wort (SJW) extract and two narcotic (opioid) pain medications: oxycodone and fentanyl. In the case of oxycodone, we are interested in whether SJW treatment promotes the metabolism of oxycodone, such that it lowers the effectiveness of standard doses of oxycodone in treating pain problems. For the fentanyl study, we will investigate whether SJW treatment will interfere with the delivery of fentanyl to the brain and diminish it's effectiveness to relieve pain. There is evidence to suggest that SJW treatment may increase the activity of a transporter protein, named P-glycoprotein (Pgp), in the blood-brain barrier (BBB) that protects the brain from exposure to drugs and other dietary and environmental toxins.
