Jon,
  I wouldn't worry about interspecific metabolic rate for dosages of
amphetamine , or for most any other drug either. Dosages are normally
geared to the pharmacokinetic compartments where the drugs are dis-
posed to end up. Dosages are based on milligrams of drug per kilogram
of body weight. So for the most part, a dose of drug for a mouse given
in mg/kg will be just fine for a rat.
