Ibuprofen works wonders for your headaches, joint pain, muscle aches, and menstrual cramps, so it's probably no surprise that it's the second most common over-the-counter (OTC) drug behind paracetamol (Tylenol), according to a 2023 article https://pubmed.ncbi.nlm.nih.gov/36876700/ in the European Review for Medical and Pharmacological Sciences. You might get a prescription for ibuprofen if you have rheumatoid arthritis or osteoarthritis to reduce the pain and swelling from these conditions. Ibuprofen might also be used for psoriatic arthritis, arthritis of the spine, and gouty arthritis. Like other non-steroidal anti-inflammatory drugs (NSAIDs), ibuprofen works by blocking an enzyme that makes prostaglandins that cause...

Prostaglandin, a potent bone-resorbing agent, is synthesized in osteoblast-like cells. Since vitamin K reportedly plays an important role in (viscosity, clotting &) bone metabolism, we investigated the effects of vitamin K2 (menatetrenone) on PGE2 production by human osteoblast-like periosteal cells. In cells incubated with menatetrenone (1 microgram/mL = 2.25 x 10(-6) M) for 2 days, PGE2 production was reduced to 50% of that in untreated control cells. In one of these menatetrenone at doses of 0.5-10 micrograms/mL dose dependently inhibited the calcium ionophore A23187-induced release of arachidonic acid (AA) from membrane phospholipids, and in the other the conversion of AA...
