Abstract
Breakthrough pain is still one of the pains that is not optimally and timely resolved. The difference in the approach to the treatment of breakthrough pain is given by the rate of onset of breakthrough attack episodes.
In particular, early treatment of breakthrough pain of these types is necessary. A novelty of rapid-release oxycodone is available for slow-onset episodes, and various forms of transmucosal fentanyl are used for fast-onset episodes.
