An analgesic (also known as a painkiller) is any member of the group of drugs used to relieve pain (achieve analgesia). The word analgesic derives from Greek an- ("without") and algos ("pain").
Analgesic drugs act in various ways on the peripheral and central nervous systems; they include paracetamol (para-acetylaminophenol, also known in the US as acetaminophen), the non-steroidal anti-inflammatory drugs (NSAIDs) such as the salicylates, and opioid drugs such as morphine and opium. They are distinct from anesthetics, which reversibly eliminate sensation.
In choosing analgesics, the severity and response to other medication determines the choice of agent; the WHO pain ladder, originally developed in cancer-related pain, is widely applied to find suitable drugs in a stepwise manner. The analgesic choice is also determined by the type of pain: for neuropathic pain, traditional analgesics are less effective, and there is often benefit from classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants.
Tell me who is next?
And who was the last one?
No word to disturb this endless beauty,
a single thought will prove me wrong!
A single thought will prove me wrong
as if it was my last one!
Come see, without the color
there`s nothing left to love.
Say good-bye to all your memories
Don`t ask me why!
I count my yesterdays.
Soul surgery, electric dream treatment,
eyes turned blind that once could see...
Es gibt kein zweites wiedersehen
im schlaf, mein bruder
Wirst du mich schon verstehen
bevor ein neuer tag vergeht, nur du...
Fangst du mir einen traum.
So please be quiet in this room,
