Tenuate and Phentermine do the same thing. Phentermine real name, brand name is Adipex. Diethylpropion real name, brand names are (Tenuate, Tepanil thin tab or ten tab). They both are appetite suppressant. Diethylpropion is also more well know as the antidepressant Wellbutrin, because bupropion which is the active ingredient in Wellbutrin is derived from Diethylpropion.
So in what they do, they are not any different, they just have different side effects! Go to WebMD or other PDR reference site and you will see that both Tenuate and Phentermine are listed as cross references, because they are effectively the same type of sympathomimetic stimulant drug.
