Local Anesthesia
Local Anesthetic Drug Pramoxine Hydrochloride Powder CAS：637-58-1
Description
Pramoxine, also known as pramocaine, is different from other local anesthetic compounds in chemical structure. Active groups which are carboxylic acid derivatives like ester and amide are not present in this molecule. The drug molecule consists of ether functional groups that are much less active on a chemical level. The presence of the free radical morpholine in this compound is the cause of the reduction of the factor of toxicity and pharmacological activity. In pramoxine, toxicity is reduced but the local anesthetic affect is maintained.
Uses
Pramoxine Hydrochloride is used as a local anaesthetic and often in anti-itch formulations that provides temporary relief from itching caused by insect bites, minor skin irritations, poison ivy, sunburn and more.
Pramoxine is used to temporarily relieve itching and pain caused by minor skin irritation such as minor burns/cuts/scrapes, sunburn, eczema, insect bites, cold sores, or rashes from poison ivy, poison oak, or poison sumac. Some products containing pramoxine are also used to temporarily relieve the itching and discomfort from hemorrhoids and certain other problems of the genital/anal area (such as anal fissures, itching around the vagina/rectum).
Indications
Pramoxine hydrochloride (Itch-X, PrameGel, Prax, Tronothane, AmLactin AP) is a local anesthetic that is structurally similar to dyclonine and unrelated to the esteror amide-type compounds.Apply to affected area t.i.d. to q.i.d., as directed by a physician. Useful for patients sensitive to ester and/or amide anesthetics. Onset of anesthesia is within minutes. Duration of anesthesia is 2 to 4 hours.
Clinical Use
Pramoxine is an amino-ether which, like dyclonine, is used as a topical agent in the form of its hydrochloride. Pramoxine hydrochloride may be used for anaesthesia of minor skin wounds and the relief of haemomhoids and other anorectal disorders.The drug is an ingredient of many proprietary topical products, and the U.S.P. has official cream and gel formulations.
Tips: hcl soluble in water, base insoluble in water. (Some Base dissolves in hot water!)
Local anesthesia strength: the anesthesia effect of some base is stronger than hcl)
