Randomized Controlled Trial
Improving Patient Knowledge and Safe Use of Opioids: A Randomized Controlled Trial.
The use of opioid analgesics in the United States has significantly increased in recent years. However, there is minimal consensus on what discharge counseling should accompany these high-risk prescriptions and large variations in what is done in practice. The objective of this study was to evaluate the effect of a dual-modality (written and spoken) literacy-appropriate educational strategy on patients' knowledge of and safe use of opioid analgesics. ⋯ This simple strategy improved several, but not all, aspects of patient knowledge and resulted in fewer patients in the intervention arm driving while taking hydrocodone. Integration of a patient education document into conversations about opioids holds promise for improving patient knowledge about these high-risk medications.

Efficacy of tramadol-acetaminophen tablets in low back pain patients with depression.
Tramadol-acetaminophen tablets are currently used to treat pain, including that of degenerative lumbar disease. Although there are many reports on tramadol-acetaminophen tablets, treatment outcomes in low back pain (LBP) patients with depression remain uncertain. This study investigated the outcomes of LBP patients with depression treated with tramadol-acetaminophen tablets. ⋯ This investigation found that tramadol-acetaminophen is effective for reducing LBP and provided a prophylactic antidepressant effect in chronic LBP patients with depression.

Randomized Controlled TrialAn assessment of the pharmacokinetics of a sustained-release formulation of a tramadol/acetaminophen combination in healthy subjects.
To provide consistent pain relief and improve convenient sustained release (SR), a fixed-dose combination tramadol/acetaminophen tablet was formulated. This study aimed to evaluate the pharmacokinetic profiles of an SR 75-mg tramadol/650-mg acetaminophen formulation after a single dose compared with an immediate release (IR) 37.5-mg tramadol/325-mg acetaminophen formulation after 2 doses and at steady state and to assess the effect of food on the pharmacokinetic SR formulation profile after a single dose. ⋯ The SR combination tramadol/acetaminophen tablet exhibited similar exposure and absorption rates compared with those of the IR formulation of tramadol, O-desmethyltramadol, and acetaminophen. The SR formulation may be more convenient for patients and has the potential to enhance compliance and pain control. ClinicalTrials.gov identifier: NCT01880125.

Randomized Controlled TrialIncreased bioavailability of phenylephrine by co-administration of acetaminophen: results of four open-label, crossover pharmacokinetic trials in healthy volunteers.
Over-the-counter combinations containing acetaminophen and phenylephrine for treatment of the common cold and influenza are widespread, but there are few data about pharmacokinetics of these two drugs used in combination. We aimed to investigate pharmacokinetic interactions between acetaminophen and phenylephrine. ⋯ The relative bioavailability of phenylephrine was increased when co-administered with acetaminophen.

Endogenous Pain Modulation in Response to Exercise in Patients with Rheumatoid Arthritis, Patients with Chronic Fatigue Syndrome and Comorbid Fibromyalgia, and Healthy Controls: A Double-Blind Randomized Controlled Trial.
Temporal summation (TS) of pain, conditioned pain modulation (CPM), and exercise-induced analgesia (EIA) are often investigated in chronic pain populations as an indicator for enhanced pain facilitation and impaired endogenous pain inhibition, respectively, but interactions are not yet clear both in healthy controls and in chronic pain patients. Therefore, the present double-blind randomized placebo-controlled study evaluates pains cores, TS, and CPM in response to exercise in healthy controls, patients with chronic fatigue syndrome and comorbid fibromyalgia (CFS/FM), and patients with rheumatoid arthritis (RA), both under placebo and paracetamol condition. ⋯ This study evaluates pain scores, TS, and CPM in response to submaximal exercise in 2 different chronic pain populations and healthy controls. In patients with RA, exercise had positive effects on TS, suggesting normal EIA. In patients with CFS/FM, these positive effects were only observed after paracetamol and results were inconsistent.
