TOPICS
• Introduction of Pain, Inflammation and Fever
• Pharmacology (Mechanism of Action of Brufen)
• Indications and Contraindications of Brufen
• Pharmacokinetics
• Pharmacodynamics (Dose)
• Brufen vs Paracetamol
PAIN AND INFLAMMATION
• Pain is an unpleasant sensory and emotional experience associated with actual
and potential tissue damage, and described in terms of such damage.
• Inflammation is a natural biological response produced by the tissues within our
body as a reaction to the harmful stimuli in order to eradicate the necrotic cells
and initiate the tissue repairing process
• The normal physiological perception of pain is known as nociception.

TYPES OF PAIN
Acute Pain Chronic Pain
Short-term, often self- limiting. Lasts months or years.
Sympathetic nervous system activity e.g.
elevated pulse and blood pressure.
Physiological adaptation e.g. normal pulse
and blood pressure.
Responsive to standard treatments. Unresponsive to standard treatment.
For example: Dental pain, Lower back pain,
Headache
For example: Cancer pain, Rheumatoid
arthritis, Osteoarthritis
FEVER
• Fever is an increase in body temperature resulting from infection or inflammation.
• Normally body temperature is maintained by hypothalamus at about 37°C
(98.6°F).
• In case of microbial infection certain white blood cells release a chemical known
as endogenous pyrogen.
• Endogenous pyrogen raises the set point of the thermostat and the
hypothalamus maintains temperature at a new higher level.
• Endogenous pyrogen raises the set point during fever by triggering the
release of prostaglandins. These act directly on the hypothalamus.

Note
NSAIDs reduce fever by inhibiting the production of prostaglandins. They
have no effect on normal body temperature because prostaglandins are
produced only in the presence of endogenous pyrogen.

Brufen
Brufen
Brufen is Non-selective Cycloxygenase
(COX) inhibitor.
INDICATIONS:
Brufen has three principal pharmacological actions.
• Anti-inflammatory
• Antipyretic
• Analgesic.
CONTRAINDICATIONS:
• Known Hypersensitivity to Ibuprofen.
• Patients who have experienced asthma, urticaria or allergic type reactions after
taking aspirin or other NSAIDs.
• Patients with severe heart failure, liver failure and Renal failure.
PHARMACOKINETICS
• Absorption: Brufen is rapidly absorbed following oral administration and peak serum levels
are achieved within 1-2 hours. Bioavailability is 80-100%.
• Distribution: Protein binding of Brufen is >90% and concentration >20 mcg/mL
• Metabolism: Brufen is metabolised in Liver into inactive metabolites.
• Elimination: Half Life approx. 2 hours, eliminated mainly through urine.
PHARMACODYNAMICS
Age Dose Frequency
3 to 6 months (weight >5 kg) 5 mg/kg 3 times a day
6 months to 1 year 2.5 ml (50 mg) of Brufen suspension 3 times a day
1 to 2 years 2.5 ml (50 mg) of Brufen suspension 3 to 4 times a day
3 to 7 years 5 ml(100 mg) of Brufen suspension
OR
2.5 ml (100 mg) of Brufen DS
3 to 4 times a day
BRUFEN VS PARACETAMOL
• Brufen provides Rapid onset of action as compare to acetaminophen.
• Brufen provides greater degree of fever reduction as compare to
paracetamol
• Brufen provides longer duration of action as compare to paracetamol.
• Brufen has anti-inflammatory effect while paracetamol not.
• Brufen is available in delicious orange flavour.
BRUFEN®Syrup produces significantly
greater fever reduction than paracetamol
syrup 4 hours after the first dose.
IBUPROFEN PRODUCES A MORE RAPID AND A GREATER AND
LONGER ANTIPYRETIC EFFECT THAN PARACETAMOL
BRUFEN SYRUP PRODUCES GREATER FEVER CONTROL THAN PARACETAMOL SYRUP IN CHILDREN
(SINGLE DOSE)
