ULTRACET┬« contains tramadol HCl and acetaminophen. Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed 4,000 milligrams per day, and often involve more than one acetaminophen-containing product (see WARNINGS).
ULTRACET┬« (tramadol hydrochloride/acetaminophen) Tablets combines two analgesics, tramadol 37.5 mg and acetaminophen 325 mg.
ULTRACET┬« is indicated for the short-term (five days or less) management of acute pain.

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.

|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 |
