Viaskin Peanut is a different type of therapy – it's an allergy vaccine administered as a skin patch containing peanut protein, which increases the patient's tolerance to those proteins over time.
From 1990 to 1996 there were increases in the legal use of fentanyl (1,092 percent - an extremely large increase because it is now available in an easily administered patch form), morphine (49percentt), oxycodone (15percentt) and hydromorphone (12percentt) -- and a decrease in meperidine (39percentt).
However, he noted, not everyone properly administered the patch on their first try.
Opinion about the comfort of drug administered by patch and preferences of patients were not assessed in these studies because the trials were double dummy and the patch was applied in all patients.
