A team of U.S. researchers reported on Wednesday that according to a new study conducted on worms, an antidepressant called mianserin might lengthen life. The drug appears to have extended by about 30 percent the life span of the nematode Caenorhabditis elegans, and although there is a major difference between worms and humans, the scientists hope to find out whether the antidepressant has the same effect on people.
But even if mianserin helped us live longer, we would have to think twice whether to use it or not, as the life-extending benefits come at a cost. According to Michael Petrascheck of Fred Hutchinson Cancer Research Center in Seattle, “Weight gain and increased appetite seems to be one of the side effects. It is one of the reasons these are not such popular antidepressants.”
The team of researchers led by Nobel Prize recipient Linda Buck did a random search through 88,000 different drug compounds before finding four drugs that extended life span by 20 to 30 percent; mianserin, which makes part from a class of drugs known as tetracyclic antidepressants, had the strongest effect.
