34 adult (>18 years) cancer pain outpatients with Opioid base therapy because of pain and
breakthrough pain or extreme pain on movement will be included in this prospective,
randomized, double-blind crossover study.
Over a period of 3 weeks patients will go through 3 treatment arms, each one lasting one
week: Group A receives morphine drops and Placebo spray, Group B receives ketamine/chitosan
spray nasal and Placebo drops and Group C receives morphine drops and ketamine/chitosan spray
nasal.

drops. Secondary endpoint is the median numeric rating scale (NRS) improvement after using
the spray or morphine or the combination of ketamine spray and morphine drops.
