Proparacaine hydrochloride(Cas 5875-06-9) Usage


Proparacaine hydrochloride is a local anesthetic eye drop medication commonly used in the United States. Its primary use is in ophthalmology for its rapid and short-acting numbing effect on the surface of the eye. Ophthalmologists and eye care professionals administer Proparacaine prior to various eye procedures and examinations, such as tonometry (eye pressure measurement), foreign body removal, and some surgical interventions like cataract surgery and corneal procedures. By numbing the eye's surface, it helps alleviate discomfort and reduce the patient's blink reflex during these procedures, making them more manageable and less painful for the individual undergoing the examination or surgery.
