- Background
Hexylcaine hydrochloride is also known as cyclaine and osmocaine. It is a short acting local anesthetic that acts through inhibition of sodium channels. Patients experience an overdose may present with headache, tinnitus, numbness and tingling around the mouth and tongue, convulsions, inability to breathe, and decreased heart function. Hexylcaine has been discontinued in the US market.

Hexylcaine is a local ester-class anesthetic. Local anesthetics produce a transient block of nerve conduction by interfering with sodium channels. This effect of the anesthetic interferes with the development of an action potential across the nerve.
- Mechanism of action
Hexyl caine acts mainly by inhibiting sodium influx through voltage gated sodium channels in the neuronal cell membrane of peripheral nerves. When the influx of sodium is interrupted, an action potential cannot arise and signal conduction is thus inhibited. The receptor site is thought to be located at the cytoplasmic (inner) portion of the sodium channel.
