How do painkillers certainly work?
How do they kill the pain?
Answers:
Basically, they change the way your brain interprets throbbing so the pain is not as noticeable.
What types of painkillers?
Paracetamol/Acetaminophen (Tylenol, Panadol)?
NSAID's (ibuprofen, Aspirin, Toradol)
or Opiates (narcotic analgesics such as Morphine and Codeine)
In broad, opiates bind to μ-opioid receptors (aka mu, from the word morphine). There are also several other opioid receptors such as delta and kapa.
The opioid receptor sites are normally activated by indigenous opioid polypeptides: enkephalins, beta-endorphins, dynorphins, and
endorphins. These chemicals all instinctively occur in the body to reduce throbbing. They also interact with Nociceptors, sensory receptors that send pain signals. These receptors are fairly blocked by both indigenous opioids like enkephalins or by drugs like morphine. Antidepressants, now used to give a hand reduce pain, will partially block nociceptors.
So opiates close to morphine simply trick the body by acting like the body's indigenous opioids.
Much of what opiates due is to alter to sensation of pain. Often people will describe, after anyone given pain killers, a feeling of euphoria and "not kindly." So even if the pain is there it does not FEEL as bad. A side effect from opiate abusers (especially IV Heroin users) is a profound apathy (not caring), so they stop benevolent about anything.
Nothing really "kills" pain. Narcotic is from a Greek term goal "to numb." NSAID's like Aspirin reduce swelling. Swelling often cause pain so the reduction is swelling reduces strain. Tylenol/Panadol is, for the most part, an NSAID but it is involved in certain chemical reaction that cause it to act slightly differently.

Painkillers work by raising your agony threshold. Simply put, acetaminophen raises the threshold just enough that your headache go away. Morphine on the other hand can raise it so much that the pain from surgery can be alleviated. Source(s): Pharmacist
