Leaves of the coca plant (Erythroxylum novogranatense var. Novogranatense), from which cocaine, a naturally occurring local anesthetic, is derived [1] [2]. An anesthetic (American English) or anaesthetic (British English; see spelling differences) is a drug used to induce anesthesia — in other words, to result in a temporary loss of sensation or awareness.
Topical tac is a topical anesthetic solution [1] introduced by Pryor et al. in 1980. It is a mixture of 5 to 12% tetracaine, 0.05% adrenaline, and 4 or 10% cocaine hydrochloride (hence the "TAC" nomenclature). It has been used in ear, nose, and throat surgery and in the emergency department where numbing of the surface is needed rapidly.
Cocaine (from French cocaïne, from Spanish coca, ultimately from Quechua kúka) [13] is a tropane alkaloid that acts as a central nervous system stimulant.As an extract, it is mainly used recreationally and often illegally for its euphoric and rewarding effects.
Many local anesthetics fall into two general chemical classes, amino esters (top) and amino amides (bottom). A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, [1] providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes ...
Calixcoca, unlike other anti-cocaine vaccines, is not protein-based. [2] The material that forms the basis of the vaccine is the V4N2 molecule. [ 4 ] This molecule stimulates the immune system to produce antibodies that bind to cocaine molecules in the blood.
Some substances may have controlled or illegal uses, others may have shamanic purposes, and others are used medicinally. Examples would be social drinking, nootropic supplements, and sleep aids. Caffeine is the world's most widely consumed psychoactive substance, and is legal and unregulated in nearly all jurisdictions; in North America, 90% of ...
General anaesthetics (or anesthetics) are often defined as compounds that induce a loss of consciousness in humans or loss of righting reflex in animals. Clinical definitions are also extended to include an induced coma that causes lack of awareness to painful stimuli, sufficient to facilitate surgical applications in clinical and veterinary practice.
He proposed – mistakenly – that the cocaine was absorbed into the venous circulation and subsequently transported to the spinal cord. [ 14 ] Although Bier properly deserves credit for the introduction of spinal anesthesia into the clinical practice of medicine, it was Corning who created the experimental conditions that ultimately led to ...
