Is D-amphetamine making a comeback as a weight-loss drug?
Amphetamine
Nowadays amphetamine is a street drug, but in the 1960s doctors prescribed substances such as Benzedrine as a matter of course for people who complained of fatigue or listlessness. Benzedrine contains a mix of D and L amphetamine, just like the amphetamine found in the drugs world.
When it became clear that amphetamine is addictive [Br Med J. 1962 Jul 7;2(5296):40-3.], causes heart attacks and strokes and on top of that can lead to psychoses [Arch Gen Psychiatry. 1972 Feb;26(2):97-100.], governments all over the world banned the substance.
But before that happened doctors did experiments with preparations like Benzedrine on people with serious weight problems. According to an article published in 1947, in a period of 8 months, men could lose 13 kg and women 11 kg by taking amphetamines. [Am J Dig Dis. 1947 May;14(5):153-62.] The main reason for this is that amphetamine suppresses appetite.
Nowadays doctors occasionally prescribe amphetamine for adults with ADHD. In 2009 Canadian researchers reported that overweight people suffering from ADHD who had been prescribed amphetamine lost 15 kg weight in 15 months. [Int J Obes (Lond). 2009 Mar;33(3):326-34.]
Study
The Australians gave 14 subjects, who had an average weight of 102.4 kg, increasing doses of D-amphetamine over a period of six months. The subjects started on a dose of 5 mg D-amphetamine with breakfast and a similar dose with lunch. Every two weeks the daily dose was increased by 10 mg, until the subjects were taking two doses of 30 mg every day. If a subject developed serious side effects the dose was taken back one level.
During the course of amphetamine the subjects tried to eat more healthily and to get more exercise and at the end of the period they were advised to continue these habits.
Results
Conclusion
"However, we believe that there are a large number of individuals who are struggling to lose weight and would use dexamphetamine responsibly. Careful participant selection, close observation, and relatively short treatment period would minimize the opportunity to abuse the drug and would also reduce the risks of long-term cardiovascular complications."
"Our findings need confirmation with a larger, double-blind placebo-controlled study."
