Phentermine was approved in the United States for medical use in 1959 and has become one of the most popular drugs for weight loss across the world.
Over 7 million prescriptions are written every year. The drug stimulates the release of chemicals, or neurotransmitters, in the brain. The neurotransmitters that are increased by this drug are norepinephrine, dopamine and serotonin.
When these neurotransmitters increase you feel full and therefore eat less. Over time this can lead to weight loss, especially if accompanied by a proper diet and exercise. Phentermine is very popular because of its low cost. Often Phentermine can be used in conjunction with other weight loss methods.
