Compound Powder Of Ipecacuanha. Pulvis Ipecacuanhae cum Opio. Br. - Dover's Powder.
This is an excellent diaphoretic preparation of opium, but will be more fully treated of with the diaphoretics. I do not think that the change in the name of this preparation, made in the recent edition of our Pharmacopoeia, was judicious. If made in order that the title might be in accordance with that of the London College, it was unfortunate; for our own old title, essentially, has been adopted in the British code in preference to that of the London Pharmacopoeia; and the same discrepancy exists as before.
