Drug therapy is still often carried out according to the WHO WHO (World Health Organization) staging scheme. The severity of the pain is determined by the choice of the drug, so lighter pain is treated with less potent analgesics (the non-opioids), moderate pain with weak opioids and severe pain with strong opioids. The next higher level is initiated if the pain relief with the selected product is not achieved.
Latest research results show that with the therapy purely on the strength of pain, those affected are not always optimally helped. The choice of therapy should take into account the type of pain (receptor or nerve pain or mixed pain) in a modern pain treatment. Patients can thus have better chances for the greatest possible relief and thus improve their quality of life.
