Levocabastine is a selective second-generation H1-receptor antagonist which was discovered at Janssen Pharmaceutica in 1979. It is used for allergic conjunctivitis.[2]

As well as acting as an antihistamine, levocabastine has also subsequently been found to act as a potent and selective antagonist for the neurotensin receptor NTS2, and was the first drug used to characterise the different neurotensin subtypes.[3][4] This has made it a useful tool for the study of this receptor.[5][6][7][8][9]

The pharmaceutical drug Bilina is a combination of Levocabastine, Benzalkonium chloride, and other components and is typically used in a 0.5 mg/ml suspension as eye-drops, dispensed in 4ml bottles for the treatment of allergic conjunctivitis or similar allergic ocular conditions.[10]
