Brufen is a non-selective COX inhibitor that provides relief from pain, inflammation, and fever by inhibiting prostaglandin production. It is indicated for these conditions and contraindicated in those with hypersensitivity or severe liver, heart, or kidney issues. Brufen is rapidly absorbed and metabolized by the liver, with a half-life of around 2 hours. Dosing is based on age and weight. Compared to paracetamol, Brufen has a faster onset of action, greater fever reduction, and longer duration due to its anti-inflammatory effects.
