2003 JUN 20 - (NewsRx.com & NewsRx.net) -- Morphine alone or with naloxone may reduce the growth of certain tumors.

According to recent research from Germany, "Opioid effects on tumor growth have been a controversial topic of discussion.

"In the present study, morphine inhibited tumor cell proliferation at concentrations of greater than or equal to 10 m[micro]m. This was primarily caused by inhibition of cell cycle progression from G to S phase," wrote I. Tegeder and colleagues, University of Frankfurt.

"At higher concentrations (greater than or ...
