There are many stimulants with effects that are substantially similar to methamphetamine. One of the most common is amphetamine. Others include methcathinone and phenmetrazine.

Yes, it is a prodrug of Phenmetrazine meaning a portion of it is converetd to Phenmetrazine by the liver. It has milder amphetamine like effects and therefore is less controlled as opposed to the amphetamines. Phenmetrazine and amphetamines are under strict Schedule II of the controlled substance act. Meanwhile Phendimetrazine is a less regulated Schedule III controlled substance. Yes it acts on the CNS like the amphetamines, but with less amphetamine like effects.

An example of a milder Prodrug is Codeine. Codeine is a Prodrug of Morphine.
