The science of paracetamol
Paracetamol
Panadol range of products uses paracetamol as its basic ingredient.
Paracetamol exerts its analgesic and antipyretic effect by inhibition of prostaglandins. However, unlike non-steroidal anti-inflammatory drugs (NSAIDs), it does not have any anti-inflammatory properties or associated with any gastrointestinal adverse effects.1
Paracetamol basics
Globally, paracetamol or acetaminophen is one of the most used analgesic and antipyretic over-the-counter drugs. Both its names are derived from its chemical name, which is N-acetyl-para-aminophenol.1 From the time of its first introduction in 1955 for use in children with fever and pain, paracetamol is currently formulated as a single compound or as an active ingredient of multi-component preparations in combination with other drugs1 such as caffeine and aspirin.2
When paracetamol is taken as indicated, minimal serious side effects have been observed.15

Indications for paracetamol
Paracetamol is indicated for fever and pain relief in both adults and children.1 As it has limited side effects compared to NSAIDs, paracetamol is the drug of choice in certain groups of patients such as those with bronchial asthma, gastric ulcers, impairments in blood coagulation e.g. haemophilia and hypersensitivity to aspirin.1
Multi-active paracetamol is also available depending on the added active ingredients. These include paracetamol with antihistamine and decongestants for cold and flu;3 and with caffeine and aspirin for migraine and tension headaches.4,5

Relieves fever in 30 minutes for up to 6 hours
Relieves fever in 30 minutes for up to 6 hours
In a randomised control study, paracetamol (500 mg or 1000 mg), aspirin (500 mg or 1000 mg) or a placebo was given to 392 adults with an acute, uncomplicated fever due to a suspected viral upper respiratory tract infection. Paracetamol 500 mg showed a rapid reduction in fever as early as 30 minutes compared to the placebo group and lasted for at least 6 hours.14
