“…For a long time, only immediate-release formulations such as morphine, oxycodone, or hydromorphone were available, which start to act within about half an hour. According to current evidence-based treatment recommendations, these substances are indicated when BTcP is expected to occur, e.g., as incident pain is triggered by movement, or when a single episode lasts for more than an hour (which is rather unusual) 9,10 . Traditional recommendations (such as to use 1/6th of total daily morphine dose) are hereby based on strategies developed when only immediate-release morphine was available on the market and has -due to its pharmacokinetic properties -to be given six times per day.…”
