The Association for Palliative Medicine of Great Britain and Ireland (APM) has stated that patient preference is of particular importance when considering treatment for BTcP.2
A survey of patient preference for placebo formulations of Abstral®, a buccal/sublingual tablet (Effentora®) and a nasal spray (Instanyl®) was conducted amongst 30 patients with cancer attending day care who were receiving strong opioids for background and breakthrough episodes of cancer pain.
The participants were given a placebo of each product with instructions and were asked to access and administer it. They were then asked to make assessments of each placebo on ease of use, palatability, ease of access of and overall impression.
Responses were recorded on a Likert agree-disagree scale (1 = extreme positive, 7 = extreme negative).3
