Whether or not a patient with advanced lung cancer takes morphine has no positive effect on survival time. Morphine is nothing but a drug used for analgesia, and morphine hydrochloride tablets are usually used to deal with outbreak pain, even if it is used to deal with long-term effective analgesia, nowadays morphine is usually not used in the clinic, but methicondin or oxycontin, especially oxycontin, that is, oxycodone hydrochloride extended-release tablets, which are taken once every 12 hours, can effectively reduce the pain of the patients and improve the quality of their survival. But no matter what kind of situation it is, applying this kind of drugs will not prolong the survival period, and the most important thing is to have effective treatment for the lung cancer itself.
