> What's different about these two stimulants?
Ritalin (methylphenidate) is a non-amphetamine stimulant that was created by a chemist in 1957 in an attempt to treat ADHD for kids without having the same appetite supression and anxiety that the amphetamines have. Of course, the drug does make you just or more anxious than amphetamines, but I suppose some enjoy their appetites while on it. Frankly, I forgot what it feels like to enjoy food since getting diagnosed with ADHD, so I can't tell.
Amphetamines are amphetamines. the l isomer is in Adderall, as is the d isomer. The d isomer alone is what comprises Dexedrine.
The d isomer is the side of the amphetamine molecule most responsible for the positive effects.
The l isomer is the side of the amphetamine molecule most responsible for the negative (side) effects.
The combination of the two in Adderall may be synergistic or may cause help for people who need motivation (since the l isomer may produce the type of anxiety that causes you to worry enough to get stuff done!)
Hope you follow. The d-isomer is the most potent, the l isomer the least potent. So 5 dexedrine is roughly equal to 10mg adderall, and 10mg dexedrine roughly equal to 20mg of adderall. But I emphasize rough.
Desoxyn is d-desoxyephedrine. The generic name is "d-methamphetamine". It's the d-isomer of desoxyephedrine (or "d-methamphetamine." It's the most potent, so 5mg of Desoxyn is like having 10mg of Adderall and 10mg of Desoxyn is like having 20mg of Adderall.
Because some docs don't read the PDR, some patients claim Desoxyn "doesn't work" because they never try more than 5mg. The daily recommended dose is 20-25mg, per the PDR! So the minimum daily dose should be at least 2 5mg tablets taken 2x/day (or the target dose, anyway).
