Motrin is a brand name for generic ibuprofen, and the two products have identical active ingredients, according to RxList. The difference between brand name products and generic ibuprofen are the inactive ingredients, which vary from brand to brand, the FDA indicates.
Motrin comes in 400-, 600- and 800-milligram tablets, RxList states. Inactive ingredients may include carnauba wax, colloidal silicon dioxide, croscarmellose sodium, hypromellose, lactose, magnesium stearate, microcrystalline cellulose, propylene glycol and titanium dioxide.
Other brand names for ibuprofen include Advil, Genpril, IBU, Midol and Nuprin. Ibuprofen relieves symptoms of headache, toothache, arthritis, back pain, minor injuries and menstrual cramps, according to Drugs.com. Motrin and ibuprofen belong to a class of drugs known as nonsteroidal anti-inflammatory drugs.
Ibuprofen is a white powder, scientifically known as propionic acid, and has a melting point between 74 and 77 degrees Fahrenheit, according to RxList. People with stomach problems and heart disease may see adverse affects with ibuprofen. Patients who exhibit an allergic reaction to the medicine should stop using these pills immediately.
Ibuprofen works by blocking the enzyme that makes prostaglandins. Pain, fever and inflammation are released in the body through prostaglandins, according to MedicineNet.com. Inhibiting these enzymes reduces inflammation. The FDA approved ibuprofen for use in 1974.
