I realise my comment wasn't very clear. The way the article recommends to stimulate the resolution pathways does imply the possibility of such drugs in the future, but primarily they explain that consuming chicken, beef, eggs, fish, and fish oil or algae (for omega-3 EDA and DHA) will promote the synthesis of these substances in one's body.

Overall they are definitely not promoting the use of drugs over lifestyle improvements. They talk about lifestyle improvements throughout the article and this was my primary takeaway: exercise regularly; don't overeat; eat those things mentioned above.
