The structure of cocaine with relevant structural motifs for activity at the dopamine transporter highlighted. While it was originally thought that the 2β-carbomethoxy moiety interacted with the DAT through hydrogen bonding, subsequent research has indicated that electrostatic (ionic) interactions are the primary means of interactions with the DAT.
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.
In the 20th century, other agents such as lidocaine have replaced cocaine as a local anaesthetic. In 1888, Karl Koller moved to the United States and practiced ophthalmology in New York. He received many distinctions in his career, including being honored by the American Ophthalmological Society as the first recipient of the " Lucien Howe Medal ...
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.
Tusi (also written as tussi, tuci, or tucibi) is a recreational drug that contains a mixture of different psychoactive substances, most commonly found in a pink-dyed powder known as pink cocaine. [ 1 ] [ 2 ] [ 3 ] It is believed to have originated in Latin America around 2018. [ 4 ]
Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural block and intrathecal block, [1] is a form of neuraxial regional anaesthesia involving the injection of a local anaesthetic or opioid into the subarachnoid space, generally through a fine needle, usually 9 cm (3.5 in) long.
Dimethocaine, also known as DMC or larocaine, is a compound with a stimulatory effect. This effect resembles that of cocaine , although dimethocaine appears to be less potent. Just like cocaine, dimethocaine is addictive due to its stimulation of the reward pathway in the brain.
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.
