History of pain killers.- discoveries and developments.
Previously, pain was mostly considered a problem to manage in acute care (related to injury, for example, or surgery) or during a painful death from cancer.
The history of painkillers is fascinating and spans centuries, with significant advancements in both understanding and treatment. Here’s a brief overview:
Historical Developments
-
Ancient Times:
- Opium: Used by ancient Sumerians around 3400 BCE. It was derived from the poppy plant and used for its analgesic properties1.
- Willow Bark: Ancient Egyptians and Greeks used willow bark, which contains salicin, a precursor to aspirin2.
-
19th Century:
- Morphine: Isolated from opium in 1804 by Friedrich Sertürner. It became widely used for pain relief, especially during the American Civil War3.
- Aspirin: Synthesized by Felix Hoffmann at Bayer in 1897. It became one of the most widely used pain relievers4.
-
20th Century:
- Synthetic Opiates: Development of drugs like methadone and fentanyl, which are more potent than natural opiates.
- Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): Introduction of ibuprofen and naproxen, which provide pain relief without the addictive properties of opiates.
