What is Ibuprofen?
Ibuprofen is the Non-steroidal anti-inflammatory drug, most commonly used and chemically it belongs to propionic acid derivatives. Ibuprofen is approved as a symptomatic treatment in different medical situations like rheumatoid arthritis, acute gouty arthritis, osteoarthritis, and ankylosing spondylitis. Ibuprofen is available in drug stores and pharmacy without any prescription. Ibuprofen is available in tablets form where its strength varies from 200mg to 800mg, but only 200mg tablets can be taken from pharmacies without any prescription. Ibuprofen when taken orally it avidly bounds to proteins, and 90% is metabolized through hepatic metabolism, and its metabolites are cleared through renal excretion. Ibuprofen has a half-life of 2 hrs, and its antiarthritic effects persist even after the decline of plasma levels. Rheumatoid arthritis and osteoarthritis are treated with the doses of 800mg when given four times a day ut in case of mild pains of Rheumatoid arthritis and osteoarthritis the low doses can also be used to mitigate that pain. Ibuprofen in the doses of 400mg is taken after every 4-6 hrs for the treatment of the primary dysmenorrhea.

What is Naproxen?
Naproxen is a Non-steroidal anti-inflammatory drug and is categorized as propionic acid derivatives. Naproxen when taken orally, it is absorbed fully. Presence of food in the stomach affects the rate of absorption of the Naproxen, but it does not affect the extent of absorption of Naproxen. Naproxen attains peak plasma concentration in 2-4 hrs after the administration of the drug. Naproxen can be absorbed when given through rectal route, but rectal route administration of the Naproxen leads to less absorption as compared to the absorption of Naproxen through the oral route. Naproxen has variable plasma half-life, for example, in young ones it is 14hrs, and 28 hrs in elders and the reason behind this delay is the decline in renal function because of increased age. About 30% of Naproxen undergoes 6-demethylation. Naproxen and its metabolites are excreted as the glucoronoid and other conjugates. 90% of Naproxen is completely bound to plasma protein when taken in therapeutic doses. Naproxen crosses membranes of the placenta and appears in the milk of lactating mothers. Naproxen shows gastrointestinal disturbances. Naproxen also shows some CNS side effects like drowsiness, headache, dizziness, sweating because of fatigue and several other dermatological problems. Some patients are also allergic to Naproxen and show symptoms of pruritus and different kinds of dermatological problems. Few cases of jaundice, impairment of renal functions, angioedema are also seen in patients who are taking Naproxen.
