It is a derivative of nicotinic acid and belongs to the class of hydrazides. Naphazoline is a vasoconstrictor, which means it narrows blood vessels, and is commonly used in over-the-counter eye drops to relieve redness and congestion in the eyes. It works by constricting the blood vessels in the eye, reducing the appearance of redness. The compound is also used in nasal decongestants to alleviate congestion in the nasal passages.
