Successful pharmacologic treatment of cancer pain is founded upon careful assessment and measurement of pain before and during therapy. Strong opioids should be used timely in accordance to the WHO 3-step analgesic ladder. The oral route should always be favored. ⋯ In case of changement of route of administration the relative potency ratio of oral morphine to parenteral morphine is about 3:1. The coadministration of nonopioids is essential for the relief of cancer pain in many cases. Adjuvant drugs may provide pain relief in specific types of pain (e.g. neuropathic pain).
