(verify) xylopropamine was briefly sold as the sulfate salt, but it was not widely marketed. other related amphetamine derivatives such as 2,4-dimethylamphetamine were also investigated for the same purpose, however these drugs had negative side effects such as high blood pressure and were not very successful, mainly due to the introduction of alternative drugs like phentermine which had similar efficacy but fewer side effects. xylopropamine was also reported as having analgesic and anti-inflammatory effects but its side effect profile resulted in it never being further developed for these applications.
