what is the benefits & purpose of paracetamol, ibuprofen and caffeine?

What is paracetamol ?

Paracetamol (acetaminophen) is a pain reliever and a fever reducer. The exact mechanism of action of is not known. Paracetamol is used to treat many conditions such as headache, muscle aches, arthritis, backache, toothaches, colds, and fevers. It relieves pain in mild arthritis but has no effect on the underlying inflammation and swelling of the joint.Paracetamol may also be used for other purposes not listed in this medication guide.

Do not use more of this medication than is recommended. An overdose of paracetamol can cause serious harm. The maximum amount of paracetamol for adults is 1 gram (1000 mg) per dose and 4 grams (4000 mg) per day. Taking more paracetamol could cause damage to your liver. If you drink more than three alcoholic beverages per day, talk to your doctor before taking paracetamol and never use more than 2 grams (2000 mg) per day.

What is ibuprofen?

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

Ibuprofen 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. Ibuprofen is used in adults and children who are at least 6 months old

benefits of Caffeine

Caffeine can be a headache trigger or headache inhibitor. Caffeine can be found in beverages, chocolate and even in some popular over-the-counter and prescription pain relievers. Before a headache or migraine, blood vessels tend to enlarge. Because it contains “vasoconstrictive” properties that cause the blood vessels to narrow and restrict blood flow, caffeine can aid in head pain relief. When caffeine is added to the combination of acetaminophen and aspirin, the pain relieving effect is increased by 40%. Though caffeine does not directly cause headache, too much of the substance can trigger “caffeine rebound.” A caffeine rebound headache occurs from withdrawal of caffeine after a sufferer continually consumes too much of the substance. Though the physical side effects can be severe, only 2% of the population suffers from caffeine rebound. Although most headache sufferers can consume up to 200 mg. per day, the NHF advises patients with frequent headaches to avoid daily use. The average American consumes about 200-300 mg of caffeine a day (or the equivalent of 2-3 cups of drip coffee). - See more at: http://kalbe.com.kh/en/health/does-caffeine-trigger-or-treat-headaches/#sthash.1OVX7Yl3.dpuf
