Antibacterial agent can weaken muscle

Triclosan impairs power of heart and other muscles

A germ-fighting chemical added to many soaps, toothpastes and fabrics can interfere with how muscles contract, new research shows.

Doses of the chemical, called triclosan, needed to diminish muscle strength and blood flow in mice roughly matched those already measured in people in some parts of the United States, neurotoxicologist Isaac Pessah at the University of California Davis School of Veterinary Medicine and his colleagues report online August 13 in the Proceedings of the National Academy of Sciences. The report suggests that triclosan interferes with the movement of calcium into and out of cells.

“Calcium regulation is just so fundamental to the functioning of any organism,” observes Heiko Schoenfuss, a toxicologist and muscle physiologist at St. Cloud University in Minnesota who was not involved in the new study. “By demonstrating that calcium transport was affected,” he says, “this new study immediately opens up an en
