Applications & Uses

Uses

Ibuprofen ((±)-Ibuprofen) sodium is an orally active, selective COX-1 inhibitor with an IC50 value of 13 μM. Ibuprofen sodium inhibits cell proliferation, angiogenesis, and induces cell apoptosis. Ibuprofen sodium is a nonsteroidal anti-inflammatory agent and a nitric oxide (NO) donor. Ibuprofen sodium can be used in the research of pain, swelling, inflammation, infection, immunology, cancers[1][2][5][8].
