Rapinylâ„¢
Treatment of acute pain in cancer patients

Around 80 percent of patients suffering from cancer-related pain suffer at times from acute pain, so-called breakthrough pain (Wood Mackenzie 2004). Treatment of this type of pain is currently dominated by conventional tablets and mixtures containing morphine. For some time, a fentanyl-containing “lollipop� has also been available.
The advantage of the Rapinylâ„¢ tablet is that it rapidly disintegrates into ordered units of carriers that adhere to the sublingual mucosa and the active compound dissolves. This allows the drug to rapidly and effectively permeate the sublingual mucosa to enter the bloodstream. The result is a quicker and more predictable onset of action than with products that must be ingested in order for the drug to enter the bloodstream by passing through the stomach and being absorbed further down the intestinal tract.
