Painkillers Can Encourages Cancer Cells Growth

Morphine is highly addictive opiate analgesic that very effective when used to help relieve pain for the patients but also can make users addicted. Morphine works by crossing the protective blood-brain barrier to get to the central nervous system so it can reduce the pain symptoms.

Recent studies indicate that the use of morphine, chronic pain drug and other opiate-based pain medications can cause side effects in accelerates the growth and spread of the cancer cells. Morphine will drive cancer cells to replicate and multiply throughout the body. It also can interfere the immune response by reducing the barrier function that protects the body from the foreign invaders.

Dr. Patrick Singleton, Ph.D., author of the studies and assistant professor of medicine at the University of Chicago Medical Center argues that this discovery could change the way for the cancer patients when treated for their pain.

A solution also has been developed by the late pharmacologist Leon Goldberg of the University of Chicago by developed a drug called methylnaltrexone (MNTX) drugs in the 1980s. MNTX have been developed in an effort to minimize the side effects of painkillers such as morphine, without reducing its function to reduce the pain for the patient.

Current study shows of the MNTX works to preserve the "mu" opiate receptor function that inhibits tumor growth. Morphine can also disrupts the mu receptor, inciting the spread of cancer.

For a while in this study have not mentioned other alternatives are safer and works the same as the pain-reducing drugs for cancer patients.
