In the United States, it is classified as a Schedule IV controlled substance under the Controlled Substances Act. Phentermine, as many other prescription drugs, works with neurotransmitters in the brain. It is a centrally-acting stimulant chemically related to the amphetamines. It stimulates neuron bundles to release a particular group of neurotransmitters known as catecholamines; these include dopamine, epinephrine (formally known as adrenalin), and norepinephrine (noradrenalin). They signal a fight-or-flight response in your body which, in turn, puts a halt to the hunger signal. As a result, you lose your appetite because your brain doesn’t receive the hunger message. This is perhaps because of phentermine’s affects on leptin levels in the brain. It is theorized that phentermine can raise levels of leptin which signal satiety. It is also theorized that increased levels of the catecholamines are partially responsible for halting another chemical messenger known as neuropeptide Y. This chemical initiates eating, decreases energy expenditure, and increases fat storage. -------------------------------------------------------------------- IUPAC name: CAS number: 122-09-8 0 comments 2:38 p.m. - 2005-11-04 GENERIC NAME: phentermine Phentermine is being considered as one of the most effective drug for weight loss for our times. Its easy to use and has few side effects. The diet-drug combination of fenfluramine and phentermine, commonly known as phentermine, is taken by millions of Americans (men and women) and has been available since the late 1980s. Physicians have written more than 18 million prescriptions for phentermine, which increases the level of the brain chemical serotonin, thereby curbing the appetite and giving patients the sensation of being full. Doctors say phentermine isn't meant for people who want to lose a few pounds for cosmetic reasons. The drug is designed for people who are about 30 percent over a healthy body weight or for those who are 20 percent overweight with medical problems such as diabetes or high blood pressure. Phentermine is in a class of drugs called anorectics which decrease appetite by possibly changing brain levels of serotonin. Phentermine is a nervous system stimulator like the amphetamines, causing stimulation, elevation of blood pressure, and faster heart rates. Obesity is usually defined as being 20% over ideal weight with resultant increase in certain diseases including high cholesterol levels, heart disease, high blood pressure, gallbladder disease, type II diabetes mellitus, hardening of the arteries, and degenerative arthritis. Weight loss decreases blood pressure, cholesterol levels, and improves diabetes control. Dosing Take the missed dose as soon as you remember.
