It was created by the chemist Alfred Einhorn who gave the chemical the trade name Novocaine, from the Latin nov-(meaning "new") and -caine, a common ending for alkaloids used as anesthetics. It was introduced into medical use by surgeon Heinrich Braun. Prior to the discovery of amylocaine and procaine, cocaine was a commonly used local ...
Structurally, amino esters consist of three molecular components: a lipophilic part (ester); an intermediate aliphatic chain; a hydrophilic part (amine); The chemical linkage between the lipophilic part and the intermediate chain can be of the amide-type or the ester-type, and is the general basis for the current classification of local anesthetics.
It is a form of penicillin which is a salt of benzylpenicillin and the local anaesthetic agent procaine. [9] The salt has weak solubility, and is prepared as a suspension. Upon injection it forms a deposit within tissue (a "depot'), and the salt slowly dissolves into interstitial fluid - dissociating the two molecules into their bioactive forms over an extended pe
The Meyer-Overton correlation for anaesthetics. A nonspecific mechanism of general anaesthetic action was first proposed by Emil Harless and Ernst von Bibra in 1847. [9] They suggested that general anaesthetics may act by dissolving in the fatty fraction of brain cells and removing fatty constituents from them, thus changing activity of brain cells and inducing anaesthesia.
TMS is the only anesthetic licensed in the United States for fin fish that are intended for human consumption. The drug can have selective toxicity for poikilotherms due to their lower rate of metabolism in the liver. [1] Tricaine is an anaesthetic that operates by preventing sodium ions to enter the cell and thus silencing action potentials. [2]
General anaesthetics can be administered either as gases or vapours (inhalational anaesthetics), or as injections (intravenous or even intramuscular).All of these agents share the property of being quite hydrophobic (i.e., as liquids, they are not freely miscible—or mixable—in water, and as gases they dissolve in oils better than in water).
It was sold under the market name larocaine. During the 1930s dimethocaine gained popularity in the US as a local anesthetic. Just like cocaine and procaine, it was used during surgery, primarily in dentistry, ophthalmology and otolaryngology. However, in the 1940s, it was removed from the market because of its psychoactive effects and risk of ...
Alfred Einhorn (27 February 1856 – 21 March 1917) was a German chemist most notable for first synthesizing procaine in 1905 which he patented under the name Novocain. [2] Until that time the primary anesthetic in use was cocaine , however its undesirable side effects (including toxicity and addiction ) led scientists to seek out newer ...
