Aspirin is a medicine that relieves
pain and reduces fever.
Purpose
Aspirin is used to relieve many kinds of minor aches and pains--headaches,
toothaches , muscle pain, menstrual cramps, the joint pain from arthritis,
and aches associated with colds and flu. Some people take aspirin daily to
reduce the risk of stroke, heart attack, or other heart problems.
Description
Aspirin, also known as acetylsalicylic acid, is sold over the counter and
comes in many forms, from the familiar white tablets to chewing gum and
rectal suppositories. Coated, chewable, buffered, and extended release forms
are available. Many other over-the-counter medicine contain Aspirin.
Alka-Seltzer Original Effervescent Antacid Pain Reliever, for example,
contains aspirin for pain relief and sodium bicarbonate to relieve acid
indigestion, heartburn, and sour stomach.
Aspirin belongs to a group of drugs called Salicylates. Other members of
this group include Sodium Salicylate, Choline Salicylate, and Magnesium
Salicylate. These drugs are more expensive and no more effective than
aspirin. However, they are a little easier on the stomach. Aspirin is
quickly absorbed into the bloodstream and provides quick and relatively
long-lasting pain relief. Aspirin also reduces inflammation. Researchers
believe these effects come about because aspirin blocks the production of
pain-producing chemicals called prostaglandins.
In addition to relieving pain and reducing inflammation, aspirin also
lowers fever by acting on the part of the brain that regulates temperature.
The brain then signals the blood vessels to widen, which allows heat to
leave the body more quickly.
