Review Case Reports
The role of intravenous acetaminophen in acute pain management: a case-illustrated review.
For more than a century, acetaminophen has been recognized worldwide as a safe and effective agent for relieving pain and reducing fever in a wide range of patients. However, until recently, acetaminophen was available in the United States only in oral and rectal suppository formulations. In November 2010, the United States Food and Drug Administration granted approval for the use of a new intravenous (IV) formulation of acetaminophen for: 1) the management of mild to moderate pain; 2) the management of moderate to severe pain with adjunctive opioid analgesics; and 3) the reduction of fever in adults and children (age ≥ 2 years). This case-illustrated review of IV acetaminophen begins with a discussion of the rationale for the drug's development and proceeds to analyze the clinical pharmacology, efficacy, safety, and nursing implications of its use, both as monotherapy and in combination with other agents as part of a multimodal pain therapy strategy.

Randomized Controlled Trial Multicenter StudyA randomized, 14-day, double-blind study evaluating conversion from hydrocodone/acetaminophen (Vicodin) to buprenorphine transdermal system 10 μg/h or 20 μg/h in patients with osteoarthritis pain.
The objective of this study was to evaluate continued pain control and tolerability of converting patients from Vicodin (hydrocodone/acetaminophen; HCD/APAP) to the buprenorphine transdermal system (BTDS). ⋯ There was a similar analgesic and tolerability profile when patients treated with Vicodin for osteoarthritis pain were switched to 7-day BTDS treatment.

Randomized Controlled TrialAnalgesic efficacy of tramadol/acetaminophen and propoxyphene/acetaminophen for relief of postoperative wound pain.
Weak opioid combined with acetaminophen (APAP) has been proven to provide better analgesic efficacy and cause fewer complications than either drug alone. However, there are questions about whether different opioids, tramadol and propoxyphene, provide similar efficacy or safety. Thus, we investigated Ultracet (37.5 mg tramadol/325 mg APAP) and Depain-X (65 mg propoxyphene/650 mg APAP). The primary aims of this study were to compare the analgesic efficacy and adverse effects of single-dose oral Ultracet versus Depain-X in acute postoperative pain. ⋯ Among patients with mild to moderate postoperative wound pain, single-dose Ultracet can provide slightly better analgesic efficacy than Depain-X in terms of onset and duration. Depain-X is no longer marketed in Europe, America, Taiwan and other countries, therefore, Ultracet can serve as a good substitute for treating postoperative pain.

Randomized Controlled Trial
Intravenous acetaminophen for pain after major orthopedic surgery: an expanded analysis.
From the time that Sinatra et al. (Anesthesiology. 2005;102:822) was published to FDA apaproval of intravenous (IV) acetaminophen, an expanded analysis of the original raw study data became necessary for the regulatory submission. The following analyses were conducted: (1) sum of pain intensity differences over 24 hours (SPID24) using currently accepted imputation methods to account for both missing data and the effects of rescue; (2) efficacy results after the first 6 hours; (3) effects of gender, race/ethnicity, age, weight, surgical site, ASA Class, and serotonin antagonists; and (4) a stepwise regression analysis of why adverse events of nausea and vomiting were numerically (although not statistically) higher in the IV acetaminophen group compared with placebo. ⋯ Repeated-dose 24-hours end points were found to be as robust as previously published results. IV acetaminophen efficacy and safety appeared to be unaffected by specific subset variables.▪
