Proparacaine Hydrochloride is the hydrochloride salt form of proparacaine, a benzoic acid derivative with local anesthetic property. Proparacaine hydrochloride (Proparacaine HCl) stabilizes the neuronal membrane by binding to and inhibiting voltage-gated sodium channels, thereby inhibiting sodium ion influx required for the initiation and conduction of impulses within the neuronal cell, and resulting in a loss of sensation.

| In 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] |
