Aspirin And Salicylates - Definition, Causes, Symptoms and Cure
Aspirin And Salicylates Drug - How does Aspirin And Salicylates Works?
Type of Drug:
Aspirin pain reliever, fever reducer and anti-inflammatory agent. ASA.
How the Drug Works:
Salicylates relieve pain by inhibiting pain perception by pain receptors and by inhibiting the formation of chemicals called prostaglandins. Prostaglandins cause pain receptors to be more sensitive to pain-producing stimuli.
They reduce fever by direct action on the heat regulating center of the brain (the body’s “thermostat”). This increases the removal of heat through increased sweating and dilation (widening) of blood skin.
Salicylates also help in preventing blood platelets from clumping together to form clots.
Uses:
To relieve mild to moderate pain.
To reduce fever.
To reduce inflammation, redness, swelling (eg, in arthritis).
- Aspirin: To reduce the risk of recurrent transient is chemic attacks (TIAs) or stroke in men.
To reduce risk of death or nonfatal heart attacks (myocardial infarction) in people with previous heart attack or unstable angina.
- Unlabeled Uses: Occasionally doctors may prescribe aspirin-like pain relievers for the possible protective effect against cataract formation and to prevent toxemia of pregnancy. It may also be of benefit in pregnant women with inadequate uteroplacental blood flow.
Precautions:
- Ears: Discontinue use if dizziness, ringing in the ears, or any hearing difficulty occurs. These symptoms are indications that salicylate blood level may be too high. Temporary hearing loss disappears gradually after the drug is stopped.
- Controlled release aspirin: Because of its relatively long onset of action, controlled-released aspirin is not recommended for fevers or short-term pain relief. It is not recommended in children younger than 12 or children with fever accompanied by dehydration.
- Aspirin intolerance: Symptoms (spasms in bronchioles, hives, swelling, inflammation of the nose) occur within 3 hours after ingestion. Aspirin intolerance is more common in patients with a history of asthma and nasal polyps.
- Foods collnlning salicylate may contribute to a reaction. Some foods with curry powder, paprika, licorice, Benedictine liqueur,
- Desensitization: Desensitizationhas been successful. It should be done in a hospital. it is generally maintained with 1 aspirin/day. Any NSA/D can maintain desensitization. However, if maintenance is interrupted, sensitivity will reappear (2 to 5 days).
- Pregnancy: Salicylates cross the placenta. Avoid use during pregnancy, especially the third trimester. Aspirin studies have shown a potential effect to the fetus. Adequate studies have not been done in pregnant women. Use only if clearly needed and potential benefits outweigh the Possible hazards to the fetus.
- Breastfeeding: Salicylates appear in breast milk. Consult your doctor before you begin breastfeeding.
- Children: Administration of aspirin to children (including teenagers) with fever-causing illnesses (eg, chickenpox, flu) has been associated with the development of Reye syndrome. Reye is a rare illness characterized by vomiting, lethargy, and belligerence that may progress to delirium and coma. Safety and effectiveness of magnesium salicylate or salsaÂlate in children have not been established.
Drug Interactions:

Doses of one or both drugs may need to be modified or a different drug may need to be prescribed. The following drugs and drug classes interact with salicylates.
