Placebo analgesia persists during sleep: An experimental study.

Although placebo analgesia is a well-recognized phenomenon with important clinical implications, the possibility that placebo effects occur during sleep has received little attention. This experimental study examined whether responsiveness to acute heat pain stimuli applied during sleep could be reduced following a placebo conditioning procedure administered before sleep. Healthy individuals (n = 9) underwent polysomnographic recordings for one habituation night followed by one placebo analgesia night a...


Hemodynamic effects of intravenous, high-dose lipid emulsion with and without metoprolol infusion in healthy volunteers: a randomized clinical trial.

In a double-blinded, randomized, cross-over trial, we investigated hemodynamic effects of high-dose intravenous lipid emulsion (ILE) with/without metoprolol. Ten healthy volunteers each completed four trial days (placebo+ILE; metoprolol+placebo; metoprolol+ILE; placebo+placebo) in random order. Metoprolol was administered as an initial bolus (10 mg), followed by an infusion (50 mg) from 5 to 30 min. ILE was administered as a bolus at 12.5 min (2.5 ml/kg), followed by a 15-min infusion (0.25 ml/kg/min). On m...

Tramadol Hydrochloride at Steady State Lacks Clinically Relevant QTc Interval Increases in Healthy Adults.

We evaluated the effects of therapeutic and supratherapeutic doses of tramadol hydrochloride on the corrected QT (QTc) interval in healthy adults (aged 18-55 years) in a randomized, phase I, double-blind, placebo- and positive-controlled, multiple-dose, 4-way crossover study. Participants were randomized to receive 1 of 4 treatments (A-D), 1 each in 4 treatment periods (1-4), separated by a washout period (7-15 days). Treatment A comprised tramadol 400 mg (therapeutic dose) on days 1 through 3, tramadol ...

The objective of this study was to evaluate the electrocardiographic effects of hawthorn in healthy adult volunteers. It was double-blind cross-over trial randomized 20 healthy adult volunteers to receive either a single oral 160-mg dose of hawthorn or matching placebo. Triplicate 12-lead electrocardiograms were taken before treatment and at 1-, 2-, 4-, and 6-hr post-dose. Following at least a 7-day washout period, participants were crossed over to the opposing treatment arm and had the measurements repeate...

The Opioid Receptor Mu 1 (OPRM1) rs1799971 and Catechol-O-methyltransferase (COMT) rs4680 as genetic markers for placebo analgesia.

The placebo effect is considered the core example of mind-body interactions. However, individual differences produce large placebo response variability in both healthy volunteers and patients. The placebo response in pain, placebo analgesia, may be dependent on both the opioid system and the dopaminergic system. Previous studies suggest that genetic variability affects the function of these two systems. The aim of the present study was therefore to address the interaction between the single nucleotide polym...

Placebo Responses in Chronic Pain: State of Research and Clinical Implications.

Placebo hypoalgesia has been found to play an important role in every health care by modulating patients' responses to pharmacologically active analgesic treatments. It may be seen as reflecting the capacity for endogenous pain modulation. Enhancing the efficacy of analgesic treatments by boosting endogenous pain modulation might be particularly relevant for chronic pain patients. Research into placebo hypoalgesic responses to chronic pain is sparse, however. In healthy subjects, placebo hypoalgesia is indu...

Guanfacine treatment for prefrontal cognitive dysfunction in older participants: a randomized clinical trial.

This study evaluated the effect of the alpha-2A-adrenoceptor agonist guanfacine on prefrontally mediated cognitive functions, as well as quality of life and global function in healthy older participants. One hundred twenty-three participants aged 75 years and older were randomly assigned to guanfacine 0.5 mg, 0.1 mg, or placebo daily for 12 weeks. The primary outcome measure was the change in z-score for 6 prefrontal executive function tasks over 12 weeks (PEF6). Neither dose of guanfacine improved PEF6...

Using Placebo Beverages in Group Alcohol Studies.

Placebo beverage conditions remain a key element in the methodological toolkit for alcohol researchers interested in evaluating pharmacological and nonpharmacological factors influencing the effects of alcohol consumption. While interest in experimentally examining alcohol in social context is on the rise, there has been little research examining the effectiveness of placebo manipulations in group settings, when just one suspicious participant could potentially jeopardize the effect of the placebo on group ...

A Novel Strategy to Identify Placebo Responders: Prediction Index of Clinical and Biological Markers in the EMBARC Trial.

One in three clinical trial patients with major depressive disorder report symptomatic improvement with placebo. Strategies to mitigate the effect of placebo responses have focused on modifying study design with variable success. Identifying and excluding or controlling for individuals with a high likelihood of responding to placebo may improve clinical trial efficiency and avoid unnecessary medication trials.

Placebo and nocebo responses in other movement disorders besides Parkinson's disease: How much do we know?

Among movement disorders and medicine in general, PD is one of the conditions for which there is a greater knowledge of the placebo and nocebo responses. In other movement disorders, the knowledge of placebo and nocebo responses is less. An advance in this field is expected to contribute to a better understanding of the nature of a therapeutic benefit in clinical research and clinical practice, and mechanisms of placebo and nocebo. We conducted a review on placebo and nocebo responses in other movement diso...

Placebo acceptability in chronic pain patients: More dependent on application mode and resulting condition than on individual factors.

Placebo effects can be very effective in certain pain conditions, but their use is still highly controversial. Several studies show that patients would accept a placebo treatment under certain circumstances, particularly when they are informed prior to the treatment or when there are no effective treatment alternatives. This study examines the question, which factors influence the degree of acceptability of a hypothetical placebo application.

Roasted barley extract (mugi-cha) containing cyclo (D-Phe-L-Pro) prevents lowering of cutaneous blood flow and skin temperature under air-conditioning - A randomized, double-blind, placebo-controlled, crossover study.

Roasted barley extract (RBE), also known as mugi-cha, is a well-known healthy non-caffeinated beverage and its health functionality has been widely reported. Our previous clinical study showed that RBE affects cutaneous blood flow and skin temperature after cold water immersion, and that cyclo (D-Phe-L-Pro) is responsible for its effect. In this study, we investigated whether cyclo (D-Phe-L-Pro)-containing RBE prevents the decrease in cutaneous blood flow and skin temperature in an excessively air-condition...

Relationship of a Special Acidified Milk Protein Drink with Cognitive Performance: A Randomized, Double-Blind, Placebo-Controlled, Crossover Study in Healthy Young Adults.

A previous in vivo study with rats suggested that a special milk protein drink manufactured using an acidification procedure to suppress the aggregation of milk proteins was absorbed quickly after feeding. We performed a randomized, double-blind, placebo-controlled, repeated-measure crossover study to investigate the short-term effects on cognitive performance in 29 healthy young adult men after they consumed this drink in the morning. After an overnight fast, subjects were tested for performance in the Uch...

Increasing effort without noticing: A randomized controlled pilot study about the ergogenic placebo effect in endurance athletes and the role of supplement salience.

Previous research shows that endurance performance can be enhanced by placebo ergogenic aids. This study investigates the ergogenic placebo response, which we define as an increase in objective and physiological effort without an increase in subjective effort, in competitive cyclists. The primary objective of this study is to explore the role of supplement salience in the ergogenic placebo response, while the secondary aim is to assess whether believing to have taken an inactive placebo supplement attenuate...

Believe in what you practice.

A recent meta-analysis showed that antidepressants are more effective than placebo. In placebo-controlled trials, the placebo effect is subtracted from the verum effect to find the specific effect of each antidepressant. In clinical practice, however, the situation is the other way around: non-specific ('placebo') effects are added to the specific effect of the antidepressant and together these effects determine the outcome. The non-specific aspects comprise strength of the therapeutic relation, conviction ...

Independent effects of age and levodopa on reversal learning in healthy volunteers.

The dopamine overdose hypothesis has provided an important theoretical framework for understanding cognition in Parkinson's disease. It posits that effects of dopaminergic therapy on cognition in Parkinson's disease depend on baseline dopamine levels in brain regions that support different functions. Although functions performed by more severely dopamine-depleted brain regions improve with medication, those associated with less dopamine deficient areas are actually worsened. It is presumed that medication-r...
