Analgesics are medicines that relieve
pain. Every type of pain killer medicine has its advantages and
disadvantages. One medicine which is effective for a specific type of pain
many not be effective for another kind. So such mdesicines need to be taken
very carefully.
Purpose of Analgesics
Analgesics are prescribed to relieve pain of
all sorts - headaches , backaches, joint pain, sore muscles, menstrual
cramps and pain that results from surgery, injury or illness. While these
drugs do not treat whatever is causing the pain, they can provide enough
relief to make people more comfortable and to allow them to carry out their
daily routines.
Throughout human history, people have sought ways to reduce pain. Until
modern times, only a few effective Analgesics existed. But today, a wide
range of pain relievers are available.
How Analgesics Work?
Pain is the body's signal that something is
wrong. Pain can result from an injury, such as a broken bone, a burn or a
sprain; from overuse of muscles (including muscle tension due to stress);
from infections, such as sinus infections or Meningitis; or from natural
events, such as child birth.
Pain begins at the level of the cells. In response to injury or
inflammation, cells release chemical messengers. These chemical messengers
alert other specialized cells called Pain Receptors. The Pain Receptors send
signals to the brain. The brain interprets the signals, and we perceive
pain. Analgesics work by either blocking the signals that go to the brain or
by interfering with the brain's interpretation of the signals.

These are Non-Steroidal Anti-Inflammatory Drugs (NSAIDs). NSAIDs
relieve pain and also reduce inflammation. There is another common
analgesic, Acetaminophen provides pain relief but does not reduce
inflammation.Determining the best pain reliever depends, in part, on the
type of pain. The two main categories are acute pain and chronic pain.
