Local Anesthetic Pramoxine Hydrochloride For Pain Killer CAS NO.637-58-1

local anesthetic pramoxine hydrochloride for pain killer

description:

pramocaine hydrochloride(pramoxine hci) is a topical anesthetic discovered at abbott laboratories in 1953 and used as an antipruritic. chemically, it is p-n butoxyphenyl gammamorpholinopropyl ether hydrochloride. during research and development,pramoxine hydrochloride stood out among a series of alkoxy aryl alkamine ethers as an especially good topical local anesthetic agent.

pharmacologic study revealed it to be potent and of low acute and subacute toxicity, well tolerated by most mucous membranes and of a low sensitizing index in man. like other local anesthetics,paramoxine decreases the permeability of neuronal membranes to sodium ions, blocking both initiation and conduction of nerve impulses. depolarization and repolarization of excitable neural membranes is thus inhibited, leading to numbness.

application:

topical anesthetics are used to relieve pain and itching caused by conditions such as sunburn or other minor burns, insect bites or stings, poison ivy, poison oak, poison sumac, and minor cuts and scratches. pramocaine and dibucaine are also common ingredients in over the counter hemorrhoid preparations.

surgical anesthesia: epidural anesthesia (including epidural anesthesia during cesarean section);local infiltration anesthesia.

acute pain control: for postoperative or labor analgesia continuous epidural infusion can be used can also be intermittent medication;local infiltration anesthesia.
