Details:

Proparacaine Hydrochloride Ophthalmic Solution is a rapid acting local anesthetic suitable for ophthalmic use. With a single drop, the onset of anesthesia begins within 30 seconds and persists for 15 minutes or longer.

The main site of anesthetic action is the nerve cell membrane where proparacaine interferes with the large transient increase in the membrane permeability to sodium ions that is normally produced by a slight depolarization of the membrane. As the anesthetic action progressively develops in a nerve, the threshold for electrical stimulation gradually increases and the safety factor for conduction decreases; when this action is sufficiently well developed, block of conduction is produced.

The exact mechanism whereby proparacaine and other local anesthetics influence the permeability of the cell membrane is unknown; however, several studies indicate that local anesthetics may limit sodium ion permeability by closing the pores through which the ions migrate in the lipid layer of the nerve cell membrane. This limitation prevents the fundamental change necessary for the generation of the action potential.

Proparacaine Hydrochloride Ophthalmic Solution is indicated for topical anesthesia in ophthalmic practice. Representative ophthalmic procedures in which the preparation provides good local anesthesia include measurement of intraocular pressure (tonometry), removal of foreign bodies and sutures from the cornea, conjunctival scraping in diagnosis and gonioscopic examination; it is also indicated for use as a topical anesthetic prior to surgical operations such as cataract extraction. 

Pramocaine hydrochloride is a topical anesthetic, and used as an antipruritic.

Proparacaine Hydrochloride is a voltage-gated sodium channels antagonist with ED50 of 3.4 mM.IC50 Value: 3.4 mM(ED50) [1]Target: Sodium Channelin vitro: Proparacaine is more potent and less toxic than cocaine [1]. Proparacaine significantly increases in FHV-1 (P < 0.01), C. felis, and 28S rDNA Ct values when fusidic acid is used [2].in vivo: Proparacaine inhibits corneal epithelial migration and adhesion through alteration of the actin cytoskeleton [3]. Proparacaine acts like bupivacaine or lidocaine and produces dose-related spinal blockades of motor function, proprioception and nociception. Intrathecal proxymetacaine also produces longer sensory blockade than motor blockade [4].
