What is Adipex-P
Phentermine
The Generic name of this drug
Treatment Summary
Phentermine is a medication used to treat obesity. It was first introduced in 1959 and became popular in 1960. It is a chemical relative of amphetamine, but is not known to be addictive and has been classified as a drug with low abuse potential. Phentermine was approved for short-term weight management in 1959, but it was later discontinued after reports of abnormal valve growth in nearly 30% of consumers. In 2012, phentermine was approved alone and in combination with topiramate for a new weight loss treatment that requires lower doses of phentermine.

How Adipex-P Affects Patients
Phentermine is a drug used to help with weight loss. It works by reducing appetite and increasing resting energy expenditure. Studies have shown that people taking phentermine lose an average of 3.6 kg over 2-24 weeks, and can maintain the weight loss after treatment is stopped. Unlike other amphetamines, phentermine does not cause any stimulation, elevated blood pressure, or other side effects.
How Adipex-P works in the body
Phentermine works by releasing a chemical called noradrenaline in the brain. This chemical stimulates certain receptors in the body, creating a "fight-or-flight" response which suppresses the hunger signal. It also weakly inhibits a chemical called monoamine oxidase, though this doesn't have a major effect.
