noun
ibuprofen
A nonsteroidal anti-inflammatory drug (NSAID) used for pain relief, fever reduction, and inflammation.
頭痛がひどいので、イブプロフェンを飲んだ。
I had a bad headache, so I took ibuprofen.
Loxonin (loxoprofen) is a similar NSAID widely used in Japan, often considered stronger and faster-acting than ibuprofen for pain and inflammation.
Borrowed from English 'ibuprofen', which is derived from parts of its chemical name: iso-butyl-propanoic-phenyl.
