Ibuprofen (Nurofen): Best Pain Killer

Ibuprofen (Brand: Nurofen)  is a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing hormones that cause inflammation and pain in the body.

Nirofen is available in various dosage forms

  • Nurofen For Children )Ibuprofen 100mg/5ml)
  • Nurofen for children Chewable Capsule.

Nurofen Uses

  • Nurofen is used to reduce fever and treat pain or inflammation caused by many conditions such as headache, toothache, back pain, arthritis, menstrual cramps, or minor injury.
  • Also Used In Pain Caused By Common Cold And Flu.
  • For symptomatic treatment of Juvenile Rheumatoid Arthritis.

Nurofen Mechanism Of Action:

  • The exact mechanism of action of ibuprofen is unknown. ibuprofen is a non-selective inhibitor of cyclooxygenase, an enzyme invovled in prostaglandin synthesis via the arachidonic acid pathway. Its pharmacologic effects are believed to be due to inhibition cyclooxygenase-2 (COX-2) that decreases the synthesis of prostaglandins involved in mediating inflammation, pain, fever and swelling. Antipyretic effects is also due to action on the hypothalamus, resulting in an exaggerated peripheral blood flow, dilation, and resulting temperature reduction. Inhibition of cox-1 is assumed to cause a number of the side effects of ibuprofen including GI ulceration. ibuprofen is administered as a racemic mixture. The R-enantiomer undergoes extensive interconversion to the S-enantiomer in vivo. The S-enantiomer is believed to be the more pharmacologically active enantiomer.
