Mechanism of action
The mechanism of action of benzocaine is based on its ability to interfere with the generation and conduction of nerve impulses. benzocaine acts on the sodium channels in the nerve membrane and prevents the influx of sodium ions necessary for initiating and transmitting nerve impulses. As a result, benzocaine inhibits the propagation of pain signals, producing a localized anesthetic effect
Spectrum
benzocaine has a narrow spectrum of activity, meaning it is only effective against specific pain and sensations. It is primarily used as a topical anesthetic for pain relief in various conditions such as toothache, sore throat, sunburn, and minor skin irritations. It is also used as a local anesthetic in some over-the-counter products for oral and genital mucosal analgesia
