[The opiate pharmacopeia in France from its origins to the 19th century].

For thousands of years, opium was the main remedy against pain. Its analgesic properties have been known since antiquity, as well as its stupefacient, narcotic and addictive effects. A countless number of opiate galenical preparations had already been formulated by the beginning of our era. The best-known were electuaries, complex drugs combining multiple active substances, essentially plant-based, used to obtain beneficial effects for different aliments. These universal remedies were panaceas. Sonne opium--or opiate--based electuaries were recommended as antidotes to poison or snake venom. The best-known, Mithridate and Theriac Andromache (Venice Treacle), the latter also containing viper flesh, combined up to a hundred or so ingredients. However, this polypharmacy was criticized and it was an English doctor, Thomas Sydenham, to whom we owe the preparation of a liquid laudanum which was easier to administer than an electuary. Sydenham's laudanum (1683) was adopted by ail the pharmacopeias. Later, based on a traditional research approach, pharmacists attempted to isolate the active principles of opium. Seguin, but above ail the German pharmacist Sertürner (in 1805 and 1817) isolated morphine. Organic chemists took over from the analysts, and morphine derivatives were obtained by hemi-synthesis (heroin), and then central analgesics, or opioids, by total synthesis. Opium is no longer seen as the only supreme remedy for painful disorders, and its galenic forms have gradually disappeared from pharmacopeias.
