A master's degree should take around two years to earn, during which time you'll complete between 30 and 50 hours of coursework and finish a written thesis that is likely based on original research of some kind. At the end of your program, you'll probably have to pass written or oral examinations as well.
Ibuprofen is a phenylpropionic acid NSAID introduced into the United States in 1974 as a prescription product intended to treat arthritic conditions at daily doses of up to 2400 mg. It was subsequently approved for daily doses of up to 3200 mg/day, and then as a prescription drug to treat mild to moderate pain in 1978.
Finally, for severe pain, the guidelines call for 400 to 600 mg ibuprofen with 650 mg acetaminophen and 10 mg hydrocodone every 6 hours for 24 to 48 hours, followed by 400 to 600 mg ibuprofen with 500 mg acetaminophen every 6 hours as needed.
