The cancer trouble stops pain with the narcotic is not easy to become addicted to the _ all the people healthy net

Professor Cai Zhiji answers: The long-term clinical practice proved that take eases the pain the treatment as the goal, under the meconium class medicine convention dosage has the phenomenon which becomes addicted to is very rare. The overseas two item of big sample investigation's result indicated that produces becomes addicted to the phenomenon distinction only to account for 0.029% and 0.033%, i.e. every 10,000 example long-term use meconium class medicine stops pain in the patient, becoming addicted to is only 3, therefore, draws “the cancer painful patient long-term use meconium class medicine becomes addicted to rarely” the conclusion to have the clinical practice basis. In explained this phenomenon when truth should note, the medicine function and organism functional condition concerns this rule, namely normal and under the pathological state has the difference to the medicine response. In the cancer painful patient central nervous system has the intense ache infection, uses the meconium class medicine under this pathological state, its analgesia potency obtains the full display, but happy namely “flutters” the feeling to step down the very secondary position. In turn, the normal person does not have the chronic fierce ache condition, if the long-term use meconium class medicine, in its function ambiguity good is at the same time the analgesia potency displays without knowing where to begin, but its bad is at the same time the addictive nature has the opportunity to give full play. Moreover, after the medicine will enter human body's drug efficacy also to receive an its medicine generation of dynamics to affect, the injection medicine intravenous injection will make the blood medicine density to advance rapidly particularly, in the brain the density obvious markup will also surpass the analgesia density which will need, will achieve causes “flutters” the feeling high potency. In the early-1980s WHO proposed that since "Cancer Three Steps and ladders Pain-relieving Plan" in the 20 years, internationally has promoted with great effort in the chronic cancer painful patient uses the morphine to control, the slow release oral administration preparation (US to execute Kangting for representative who controls releases preparation), this kind of preparation applies the high tech method to cause the medicine to absorb at the gastro-intestinal tract slow release, the blood medicine density can maintain the stable analgesia density in the long time, will not cause the blood medicine density to rise rapidly causes “flutters” the feeling density.
