Pantopon

Pantopon is a preparation of opiates made up of all of the alkaloids present in opium in their natural proportions as hydrochloride salts. It can sometimes be tolerated by persons who are allergic to morphine.

Pantopon is, in other words, opium with all of the tar and other insolubles removed in an injectable form which is nearly as potent as morphine is, by weight. It was invented in 1909 by Hoffmann-La Roche pharmaceutical company. Other drugs of the same type have include opium alkaloid sulphates (Papaveretum), phosphates, and valerates.

Pantopon gave name to the poem "Pantopon Rose" by American writer William Burroughs and to a song with the same name by Northern Ireland alternative metal band Therapy? (album "Troublegum", 1994). Also, it gave name to 1996 Mexican documentary "Rosa Pantopon".
