• Description: Cocaine is best known as an illegal drug that produces a euphoric “high” in individuals who use it. Cocaine is an alkaloid obtained from the leaves of the coca plant, Erythroxylum coca, which is native to northwestern South America and Central America. Cocaine (Item No. 16186) is an analytical reference material categorized as a tropane. Cocaine has a high potential for abuse and has been found in samples seized by law enforcement. Cocaine is regulated as a Schedule II compound in the United States. This product is intended for research and forensic applications.
• Physical properties: Appearance: pure white crystal, odorless. Solubility: insoluble in water (1:600); soluble in chloroform (1:0.7), ethyl ether (1:3), ethanol (1:7), and other organic solvents; soluble in acetone, benzene, ethyl acetate, two carbonyl sulfide, and petroleum ether; show monoclinic flaky crystal in ethanol. Melting point: 98° (it can be slowly evaporated over 90°), the specific rotation of ?16°.
• Uses: Cocaine is derived from the leaves of the erythroxylum coca plant and was first used as an anaesthetic by Karl Koller in 1884. It is a potent vasoconstrictor, blocking reuptake of noradrenaline, but has significant potential for systemic toxicity. Cocaine has been used in nasal surgery as a paste or 4% solution for its properties of topical anaesthesia and vasoconstriction. Use of cocaine is known since early times.It occurs in the South American coca leaves.Chewing of leaves mixed with lime was acommon practice among natives, who traveledgreat distances without experiencingfatigue (Cordell 1978). Cocaine is obtainedby extraction of coca leaves. It is also preparedby methylation and benzoylation of thealkaloid, ecgonine. The dilute aqueous solutionsof its hydrochloride is used as a topicalanesthetic in ophthalmology. Cocaine and itsderivatives are controlled substances listedin the U.S. Code of Federal Regulations(Title 21, Parts 321.1 and 1308.12, 1987). Anesthetic (topical). It was widely used as a topical anesthetic in dentistry and in ophthalmology; it also found use as an appetite suppressant, a drug used to treat morphine addiction, a stimulant, and a general elixir. Its popularity to treat depression was originally advanced by Sigmund Freud (1856 1939). Cocaine is used medicinally for local anesthesia and vasoconstriction, especially in surgery involving the ear, nose, and throat. It is the only naturally occurring anesthetic. Although it is still used in limited quantities for surgery, many surgeons and anesthesiologists have turned to safer alternatives such as lidocaine and benzocaine. Also, the use of alternatives eliminates the storage of a well-known addictive drug in clinics and hospital pharmacies.
• Indications: It is mainly used for local anesthesia in various operations. It is also suitable for nasal, pharyngeal, ear, urethra, vagina, and other operations (with 5–10% solution). 2% to 3% solution is used for eye surgery.
• Clinical Use: Cocaine has a very interesting history. The coca plant was used by South American Indians for religious and mystical purposes and as a stimulant both to increase endurance and to alleviate hunger. It was introduced into Europe during the 1800s, and at the end of the 19th century, cocaine use was popular and socially acceptable. Various cocaine-containing preparations were available, and it also was used to “fortify” wines (e.g., Vin Coca). For a period of approximately 20 years, until just after the turn of the century, it was a constituent of the soft drink Coca-Cola. Additionally, cocaine was used for therapeutic reasons but was later supplanted by amphetamine.
