History of Phentermine 37.5
Phentermine was first used in 1959, but was pulled from the market in 1997. They pulled this drug from the market because it contained fenfluramine. Fenfluramine directly affects the serotonin neurotransmitters in your brain. Serotonin is a neurotransmitter that regulates appetite and mood and some other functions. Basically fenfluramine makes your brain think that these serotonin neurotransmitters are being released and you feel full without even eating. Fenfluramine was banned from the United States and then the rest of the world because it was causing heart valve disease and cardiac fibrosis. Since this drug is in Phentermine, it had to be pulled from the shelves as well. Improvements on the drug were made and it was then approved in the U.S. in 2012.
