Oxybuprocaine is the name of a local anesthetic, which is used especially in ophthalmology and otolaryngology. Oxybuprocaine binds to sodium channels and reversibly stabilizes the neuronal membrane which decreases its permeability to sodium ions.
Indication
Used to temporarily numb the front surface of the eye so that the eye pressure can be measured or a foreign body removed.
Pharmacology
Oxybuprocaine is a local anaesthetic. It may be less irritating than tetracaine, and the onset and duration of action are similar to tetracaine.
A benzoate ester in which 4-amino-3-butoxybenzoic acid and 2-(diethylamino)ethanol have combined to form the ester bond; an ester-based local anaesthetic (ester "caine") used especially in ophthalmology and otolaryngology.
