Weight Loss Diet Drugs (we should say Weight Loss AND Diet Drugs) have been mentioned in the same breath for years. Weight loss diet drugs came on the market in the 1950’s, apparently in the form of amphetamines or speed. Amphetamines or speed are very potent psychomotor stimulants that cause your body to release excitatory neurotransmitters such as dopamine and noradrenaline, also known as norepinephrine.
Weight loss diet drugs such as amphetamines can be sniffed, swallowed, snorted and injected into the bloodstream and tend to induce exhilarating feelings of power, strength, energy, self-assertion, focus and enhanced motivation. No wonder many used speed for all-night studying purposes or to get through other all-night activities, i.e., graveyard shifts.
After taking an amphetamine, your body “forgets” the need to sleep or eat. No wonder weight loss diet drugs came to be used as a serious alternative to those wishing to shed pounds quickly. Dopamine usually induces a sense of aroused euphoria that can last many hours. In addition, amphetamines are not broken down by the body as readily as other drugs such as cocaine which can lead to intensified feelings and empowerment.
Because amphetamines are stimulants, they cause the body to burn calories. But, they also came to be known as addictive drugs that were proven unsafe. As a result, the FDA ruled that they be pulled from the market. However, weight loss diet drugs are still popular due to their convenience and availability. Weight loss diet drugs as you can read in this site can assist you in losing weight initially but it is your dietary behavior and exercise patterns that will determine your long term health.
Weight Loss and Diet Drugs: Fen-Phen
For many years, fen-phen was used as a weight loss diet drug to combat obesity and to increase weight loss. Fen-phen refers to the combination of fenfluramine and phentermine. Fenfluramine (fen) and phentermine (phen) were approved by the FDA as prescription diet drugs that suppressed appetite for the short term treatment of obesity. Fenfluramine was approved by the FDA in 1973 and phentermine was approved in 1959.
Troubling reports of fen-phen side effects began to surface in 1997. In July, the Mayo Clinic reported that 24 patients developed regurgitation or leakiness in their heart valves after taking fen-phen. Then, there followed cases of other patients with heart valve disease after having been on a fenfluramine regimen. There were NO cases of heart valve disease in anyone taking just the phentermine diet drug. Based on additional findings and cases brought to the attention of the FDA, just the drug fenfluramine was pulled from the market.
The phentermine diet drug was not pulled from the market because all studies pointed to fenfluramine (and dexfenfluramine) as the cause of heart valve disorders.
