Published Studies Related to Ultracet (Tramadol / Acetaminophen)
Pharmacokinetics of extended-release versus conventional tramadol/acetaminophen fixed-dose combination tablets: an open-label, 2-treatment, multiple-dose, randomized-sequence crossover study in healthy korean male volunteers. [2011.06]
BACKGROUND: A fixed-dose combination tablet of tramadol/acetaminophen exhibits both rapid and sustained analgesic effects due to different pharmacologic activities. To prolong analgesia and improve patient convenience, an extended-release (ER) tablet of this agent has been developed. OBJECTIVE: The aim of this study was to explore the pharmacokinetic profiles of the new ER tramadol/acetaminophen fixed-dose combination and compare them with those of a conventional immediate-release (IR) formulation after multiple dosing as a Phase I clinical exploratory trial... CONCLUSIONS: The ER formulation displayed a similar AUC(0-12,ss) to that of the IR formulation for tramadol and acetaminophen. Copyright (c) 2011 Elsevier HS Journals, Inc. All rights reserved.
Comparison of efficacy and effectiveness between ULTRACET and tramadol/acetaminophen in acute postoperative pain after upper extremity surgery. [2010.07]
OBJECTIVE: To compare the efficacy and effectiveness between ULTRACE, a new analgesic combination of tramadol/ acetaminophen, and tramadol/acetaminophen for acute postoperative pain after upper extremity surgery... CONCLUSION: ULTRACET has more efficacy and fewer side effects when compared with tramadol and acetaminophen in acute postoperative pain surgery.
Ultra low-dose naloxone and tramadol/acetaminophen in elderly patients undergoing joint replacement surgery: a pilot study. [2009.03]
OBJECTIVE: A pilot study was conducted to assess whether both the rationale and feasibility exist for future randomized clinical trials to evaluate the combined use of naloxone infusion and tramadol/acetaminophen as opioid-sparing drugs in elderly patients undergoing lower extremity joint replacement surgery... CONCLUSION: Consequently, a randomized, double-blinded clinical trial comparing standard therapy versus standard therapy plus these two drugs seems warranted. In such a trial, it would require approximately 20 subjects per treatment arm to detect a 80% decrease in morphine use.
A 2-week, multicenter, randomized, double-blind, double-dummy, add-on study of the effects of titration on tolerability of tramadol/acetaminophen combination tablet in Korean adults with knee osteoarthritis pain. [2007.07]
BACKGROUND: Combined tramadol/acetaminophen is used to treat pain related to osteoarthritis. However, adverse events (AEs) leading to discontinuation can occur. Dose titration may decrease the risk for AEs. OBJECTIVE: The aim of this study was to assess the effect of tramadol/acetaminophen titration on the development of AEs leading to treatment discontinuation in patients with knee osteoarthritis... CONCLUSIONS: In this population of Korean patients with knee osteoarthritis pain managed with a stable dose of NSAIDs, titration of tramadol/acetaminophen over 12 days was associated with improved tolerability and a significantly lower discontinuation rate compared with nontitration. Both regimens significantly reduced from baseline associated with osteoarthritis.
Tramadol/acetaminophen or hydrocodone/acetaminophen for the treatment of ankle sprain: a randomized, placebo-controlled trial. [2007.04]
STUDY OBJECTIVE: This randomized, multicenter study compares the analgesic efficacy and safety of tramadol/acetaminophen versus hydrocodone/acetaminophen versus placebo for the treatment of acute musculoskeletal pain caused by ankle sprain... CONCLUSION: One or 2 capsules of 37.5 mg tramadol/325 mg acetaminophen and 1 capsule of 7.5 mg hydrocodone/650 mg acetaminophen were well tolerated, had comparable clinical utility, and were more effective than placebo in the management of acute musculoskeletal pain caused by ankle sprain.

A Study to Assess the Bioequivalence of a New ULTRACET Extended Release (ER) Tablet With Respect to a Marketed ULTRACET ER Tablet Under Fasted Condition [Recruiting]
The purpose of this study is to evaluate the bioequivalence of a newly developed ULTRACET
extended-release (ER) tablet of tramadol hydrochloride and acetaminophen, to the current
marketed ULTRACET ER tablet, in healthy participants under fasted condition.
A Study to Evaluate the Clinical Benefits of Tramadol/Acetaminophen (Ultracet) Versus Diclofenac in the Treatment of Pain in Patients With Ankylosing Spondylitis Receiving Stable Treatment of Disease Modifying Anti-Rheumatic Drugs (DMARDs) [Not yet recruiting]
The purpose of the study is to investigate the clinical benefit of Tramadol/Acetaminophen
(Ultracet) vs. NSAID (Diclofenac 50 mg) in the treatment of pain in patients with ankylosing
spondylitis receiving stable treatment of disease modifying anti-rheumatic drugs (DMARDs).

Tramadol/Acetaminophen(Ultracet) AS Add-on Therapy in the Treatment of Patients With Ankylosing Spondylitis [Not yet recruiting]
Ankylosing spondylitis (AS) is a chronic inflammatory arthritis causing back pain,
peripheral arthritis and enthesitis due to genetic background and autoimmunity. Patients
with ankylosing spondylitis usually suffered from chronic pain over spine and peripheral
joints since their second or third decades. It may also cause severe social and
psychological burden to patients and their family.
Exercise and non-steroid anti-inflammatory drugs (NSAID) are the standard first-line
treatments for AS（1）. Only 50% of patients with AS reach the ASAS response criteria（2） in
clinical trials. Patients with severe disease activity should be put on disease-modifying
anti-rheumatic drugs (DMARD), such as sulfasalazine（3） and anti-TNF biological agents.
Add-on of acetaminophen and low dose anti-depressant （4）can slightly improve the response
rate. However, there is no data if tramadol or ultracet can benefit AS.
Tramadol 37. 5 mg/APAP 325 mg combination tablets (ULTRACETÂ®) were effective and safe as
addon therapy with COX-2 NSAID for treatment of osteoarthritis (5) and chronic low back
pain (6).There is no clinical trial regarding tramadol usage in chronic inflammatory
arthritis such as rheumatoid arthritis (RA) or ankylosing spondylitis. It would be important
to do a pilot clinical trial on add-on effect of tramadol to NSAID in patients with AS or
This Open-Label Study Will Evaluate the Analgesic Effectiveness and Safety Measurement of Tramadol HCl/Acetaminophen in the Treatment of Pain for Fibromyalgia. [Not yet recruiting]
The purpose of the study is to evaluate the analgesic effectiveness and safety measurement of
Ultracet in the treatment of pain for fibromyalgia. This is a multicenter, single arm study.
Patients receiving antidepressants, cyclobenzaprine or anti-epileptic drugs for pain prior to
entering this study, must discontinue these medications at least three weeks before entering
the Treatment Phase.

|Side effects:|| || I had a tooth infected went to the dentist for exam and antibotics, and he gave me Tramadol. I took it from 10/14/2008 to 10/16/2008 early am every 4 to 6 hrs 2 pills for pain. I woke up Thursday around 2 am took 2 more as prescribed was unable to walk due to muscle spasms. I could not go to the bathroom due to pain just made the barrel by the bed and crawled back in the bed stopped taking the pain pills after this. My Husband took me to the Doctors office carefully assisting me as I could not walk. I was paralized with extreme severe pain. He made a make shift ambulance out of a ford escort in the back making a bed and I crawled carefully in pain and laid there. The Physician office told me go to the Emg. room St Michaels Hospital. I was unable to get out of the back of the car. With assistance it took a good while to get me out and to lean on a wheelchair to try and walk with constant spasms and pain. I finally got to a bed in the emergency room and laid on my side. In less than 1 hour I had 2 shots in my rear and one in my arm informing I was having severe adverse reactions to the meds. They went from the top of my shoulders, down my back, to my stomach and legs. This was worse than having a baby and I had 3. I am still laid up today and have had a leave of absence due that I am unable to walk or sit at present. I am very upset at the slow process and the information on side affects do not talk about these adverse affects. My physician took blood and urine samples for a possible muscle problem that this adverse reaction can cause. Waiting for the results.|
|Comments:|| || Take 2 pills every 4 to 6 hrs. for pain. Not to exceed 8 pills |
