Proparacaine Hydrochloride Ophthalmic Solution 0.5%: Topical Ocular Anaesthetic

Alcaine Ophthalmic Solution contains the active ingredient Proparacaine Hydrochloride which is a rapid-acting topical Ocular Anaesthetic. While originally formulated for human medicine, it is a staple in veterinary practices for use in dogs, cats, and horses on an extra-label basis. Proparacaine works by blocking the sodium channels in the nerve endings of the eye, effectively numbing the surface of the cornea and conjunctiva within 30 seconds of application. This allows for painless diagnostic procedures and minor therapeutic treatments.
