| Bioactivity | Oxybuprocaine hydrochloride (Benoxinate hydrochloride) reversibly blocks sodium channels and prevents propagation of painful nerve impulses in the cornea, conjunctiva, and sclera. Oxybuprocaine hydrochloride is used especially in ophthalmology and otolaryngology[1][2][3]. |
| In Vivo | Oxybuprocaine hydrochloride (Benoxinate hydrochloride; 27.6, 51.7, 103.5, 413.9 μg; s.c.) provides a dose-dependent block to pinpricks in rats[1]. Oxybuprocaine hydrochloride (27.6 μg) produces 100% of sensory/nociceptive block[1]. Animal Model: |
