choline + aspirin

Choline + aspirin is a combination of two agents—choline, an essential nutrient and α7 nicotinic receptor agonist, and aspirin (acetylsalicylic acid), a non-steroidal anti-inflammatory drug (NSAID). This combination has been studied for its synergistic analgesic effects in inflammatory pain models. Choline itself exhibits antinociceptive properties via activation of α7 nicotinic receptors, muscarinic receptors, and opioid receptors. When coadministered with aspirin, the combination demonstrates enhanced potency and duration of analgesia compared to either agent alone. The mechanism involves both central and peripheral pathways for pain modulation. While not currently marketed as a fixed-dose pharmaceutical product, this combination is under investigation as a potential safe analgesic regimen for inflammatory pain[2].
