Multicenter Study Comparative Study
Supratherapeutic dosing of acetaminophen among hospitalized patients.
We investigated acetaminophen use and identify factors contributing to supratherapeutic dosing of acetaminophen in hospitalized patients. ⋯ Supratherapeutic dosing of acetaminophen was significantly associated with multiple factors. Interventions to reduce the incidence of some risk factors may prevent supratherapeutic acetaminophen dosing in hospitalized patients.

Randomized Controlled Trial Multicenter Study Comparative Study
A randomized, controlled trial comparing acetaminophen plus ibuprofen versus acetaminophen plus codeine plus caffeine (Tylenol 3) after outpatient breast surgery.
The combination of acetaminophen, codeine, and caffeine (Tylenol 3, T3) is a standard postoperative analgesia after breast surgery despite the adverse effects and variable efficacy of narcotics. This study compared the efficacy of a nonnarcotic approach (acetaminophen and ibuprofen; AcIBU) to T3 after outpatient breast surgery. ⋯ AcIBU is a safe, effective method of pain control after outpatient breast surgery. Compared to T3, it provides at least equivalent analgesia and has a more tolerable adverse effect profile.

Multicenter Study Clinical Trial
Treatment satisfaction after switching to another therapy in Spanish orthopaedic clinic outpatients with knee or hip osteoarthritis previously refractory to paracetamol.
Hip and knee osteoarthritis is highly prevalent in the elderly, and the incidence is estimated to increase in the coming decades. Prior to surgery, symptomatic treatment, starting with non-pharmacological therapies, should be prescribed. Paracetamol (acetaminophen) is the recommended first pharmacological treatment for osteoarthritis. If paracetamol is ineffective, non-steroidal anti-inflammatory drug (NSAID) treatment is indicated. The superiority of NSAIDs over paracetamol has been demonstrated in several studies. Furthermore, the assessment of patient satisfaction could be an adequate indicator of the quality of care given and is likely related to the evolution of the condition and the therapeutic regimen. The objective of this study was to assess the satisfaction of patients diagnosed with hip and/or knee osteoarthritis who had been previously treated with paracetamol and switched to NSAID treatment due to a lack of effectiveness by paracetamol. ⋯ NSAIDs relieve pain due to OA in paracetamol-resistant patients and improve treatment effectiveness and patient satisfaction with treatment. Furthermore, paracetamol-refractory subjects under conventional medical treatment with NSAIDs experienced the drug as more effective and also tended to be more satisfied with treatment than those treated with non-NSAIDs.

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 Trial Multicenter Study Comparative StudyThe efficacy of tramadol/acetaminophen combination tablets (Ultracet®) as add-on and maintenance therapy in knee osteoarthritis pain inadequately controlled by nonsteroidal anti-inflammatory drug (NSAID).
The purpose of this study is to compare the efficacy of tramadol 37.5 mg/acetaminophen 325 mg combination tablets (tramadol/APAP) with that of nonsteroidal anti-inflammatory drugs (NSAIDs) as maintenance therapy following tramadol/APAP and NSAID combination therapy in knee osteoarthritis (OA) pain which was inadequately controlled by NSAIDs. Subjects with knee OA for over 1 year and moderate pain (numerical rating scale [NRS] ≥5) despite at least 4 weeks' NSAID therapy (meloxicam 7.5 mg or 15 mg qd or aceclofenac 100 mg bid) received tramadol/APAP add-on (combination with NSAID) for 4 weeks. Thereafter, subjects with significant pain improvement (NRS <4) were randomized to receive either tramadol/APAP or NSAID for 8 weeks. ⋯ Overall adverse event rates were similar in both groups. Tramadol/APAP add-on significantly improved knee OA pain which had been inadequately controlled by NSAIDs. In those subjects who showed favorable response to tramadol/APAP and NSAID combination therapy, both tramadol/APAP and NSAIDs were effective at maintaining the pain-reduced state and there was no significant difference in efficacy between tramadol/APAP and NSAIDs.
