Carol:

 structually this is atropine and diphenhydramine.

 atopine is aap approves and dipenenhydramine is excreted in very samm
quantities.

 ths molecular weight is 403.54.... you might check to see if it can get
through..

 Hopefully Dr. Hale will come into this one.. but the above may be what the
pharmasist is looking at... you could ask how hecame to the conlusion as your
books do not show

  You might also check hale.. mine is not here..
