Trisenox, an injectable form of ARSENIC
The FDA just approved Trisenox, an injectable form of ARSENIC.
Trisenox (arsenic trioxide) is for second-line therapy of acute promyelocytic leukemia. It's very effective...up to 70% remission in patients who don't do well on standard chemotherapy.
Trisenox has an interesting origin. Scientists discovered arsenic was a common ingredient in some traditional Chinese remedies for leukemia.
