Can children swallow tablets? Outcome data from a feasibility study to assess the acceptability of different-sized placebo tablets in children (creating acceptable tablets (CAT)).

ABSTRACT: OBJECTIVE:Feasibility study to investigate the acceptability of different-sized placebo tablets in children aged 4-12 years. DESIGN AND SETTING:Clinical Research Facilities, inpatient wards and outpatient clinics within a Regional Paediatric Hospital and/or District General Hospital. Healthy children and National Health Service (NHS) patients were asked to swallow three placebo tablets: 6?mm, 8?mm and 10?mm, smallest to largest. The researcher observed children's facial expressions and behaviours on swallowing and measured the volume of water consumed. Participants completed a questionnaire about the overall acceptability; including swallowability, taste and volume of water consumed. For analysis, participants were stratified by age: 4-8 years and 9-12 years. RESULTS:The feasibility study led to an estimated recruitment rate of 0.8% for NHS inpatients and 211 healthy children over a 1-year period. In total, 55 participants were recruited, 30 to the younger group, of which 77% had never taken a tablet before. 84% of the 25 older children had previously taken a tablet. All participants attempted to swallow the smallest sized tablet. The children aged 4-8?years found the larger tablets easier to swallow, however the older children found little difference between the tablet sizes. The younger children required more water to swallow each tablet size compared with the older children where an increasing volume of water was consumed as tablet size increased. Taste was rated highly for both age groups. The 8?mm tablets were deemed the most acceptable tablet size by all participants. CONCLUSION:Tablets are potentially an acceptable formulation for children aged 4-12 years. Most children aged 4-8?years who attempted to swallow tablets successfully did so. Recruitment of NHS inpatients to medicine acceptability studies is challenging, however, recruitment of children of staff proved an effective strategy. Valuable lessons have been learnt from this feasibility study which will inform the design of a larger definitive trial.

Project description:Health care providers use treatments whose effectiveness derives partially or completely from 'nonspecific' factors, frequently referred to as placebo effects. Although the ethics of interventional placebo use continues to be debated, evidence suggests that placebos can produce clinically meaningful analgesic effects. Burgeoning evidence suggest that patients with chronic pain might be open to placebo treatments in certain contexts despite limited knowledge of their well-established psychoneurobiological underpinnings. In this investigation we sought to examine the effects of a brief, mechanism-based placebo analgesia educational intervention on aspects placebo knowledge and acceptability. Participants with chronic musculoskeletal pain completed a web-based survey in which they rated their knowledge of placebo analgesia, assessed placebo acceptability across different medical contexts, and evaluated 6 unique patient-provider treatment scenarios to assess the role of treatment effectiveness and deception on patient-provider attributions. Using a pre-post design, participants were randomized to receive either a placebo educational intervention or an active control education. Results showed that the educational intervention greatly improved perceptions of placebo knowledge, effectiveness, and acceptability, even in deceptive treatment contexts. This was the first study of its kind to show the value of an educational intervention in increasing openness to and knowledge of placebo analgesic interventions among patients with chronic musculoskeletal pain.In this we article highlight how patients with chronic pain might be open to placebo interventions, particularly adjunct and/or complementary treatments, when provided education on the neurobiological and psychological mechanisms that underlie placebo effects. Study findings highlight ethically acceptable ways to potentially use placebo factors to enhance existing pain treatments and improve patient health outcomes.

Project description:Surveys of doctors suggest that they use placebos and placebo effects clinically to help patients. However, patients' views are not well-understood. We aimed to identify when and why placebo-prescribing in primary care might be acceptable and unacceptable to patients.A purposive diverse sample of 58 English-speaking adults (18 men; aged 19-80 years) participated in 11 focus groups. Vignettes describing doctors prescribing placebos in primary care were used to initiate discussions. Data were analyzed inductively.Participants discussed diverse harms and benefits of placebo-prescribing for individual patients, carers, healthcare providers, and society. Two perspectives on placebo-prescribing were identified. First, the "consequentialist" perspective focused on the potential for beneficial outcomes of placebo-prescribing. Here, some participants thought placebos are beneficial and should be used clinically; they often invoked the power of the mind or mind-body interactions. Others saw placebos as ineffective and therefore a waste of time and money. Second, the "respecting autonomy" perspective emphasized the harms caused by the deceptive processes thought necessary for placebo-prescribing. Here, participants judged placebo-prescribing unacceptable because placebo-prescribers deceive patients, thus a doctor who prescribes placebos cannot be trusted and patients' autonomy is compromised. They also saw placebo-responders as gullible, which deterred them from trying placebos themselves. Overall, the word "placebo" was often thought to imply "ineffective"; some participants suggested alternative carefully chosen language that could enable doctors to prescribe placebos without directly lying to patients.Negative views of placebos derive from beliefs that placebos do not work and/or that they require deception by the doctor. Positive views are pragmatic in that if placebos work then any associated processes (e.g. mechanisms, deception) are deemed unimportant. Public education about placebos and their effects is warranted and research to identify optimal ways of harnessing placebo effects in clinical practice is needed.

Project description:BackgroundAbuse-deterrent formulations attempt to address public health and societal concerns regarding opioid abuse. Oxycodone HCl-niacin tablets combine oxycodone HCl with niacin and functional inactive excipients to create potential barriers to oral, intranasal, and intravenous abuse. This study compared the relative abuse potential of oral immediate-release oxycodone HCl-niacin with that of oral immediate-release oxycodone HCl and placebo in nondependent, recreational opioid users.MethodsForty-nine participants received oxycodone HCl-niacin 40/240 mg and 80/480 mg, oxycodone 40 mg and 80 mg, and placebo in a randomized, double-blind, placebo-controlled and active-controlled, five-way crossover study. Primary endpoints based on a bipolar 100 mm visual analog scale for drug liking were area under effect curve (AUE0-1h, AUE0-2h, AUE0-3h), peak disliking, and effect at 0.5 hours post-dose (E0.5h). Other endpoints included take drug again assessment, overall drug liking, and pupillometry.ResultsThere were statistically significant differences between oxycodone HCl-niacin and oxycodone HCl doses for all primary endpoints (P < 0.0001, all comparisons), suggesting reduced abuse potential with oxycodone HCl-niacin. Take drug again and overall drug liking showed greater liking of oxycodone alone. Oxycodone HCl-niacin 80/480 mg had consistently lower liking assessments than oxycodone HCl-niacin 40/240 mg, suggesting a dose-response to the aversive effects of niacin. Opioid-related adverse events were similar for equivalent oxycodone doses. The treatment-emergent adverse events most specifically associated with oxycodone HCl-niacin (ie, skin-burning sensation, warmth, and flushing) were consistent with the expected vasocutaneous effects of niacin. No serious adverse events were reported.ConclusionOxycodone HCl-niacin tablets may, in a dose-dependent manner, decrease the potential for oral abuse of oxycodone without unexpected adverse events or clinically signifi-cant differences in safety parameters compared with oxycodone alone. Although statistically powered, the small size of the study sample and the characteristics of its participants may not be generalizable to the population that abuses prescription opioid medications.
