Cocaine produces anesthesia by inhibiting excitation of nerve endings or by blocking conduction in peripheral nerves. This is achieved by reversibly binding to and inactivating sodium channels. Sodium influx through these channels is necessary for the depolarization of nerve cell membranes and subsequent propagation of impulses along the course of the nerve. Cocaine is the only local anesthetic with vasoconstrictive properties. This is a result of its blockade of norepinephrine reuptake in the autonomic nervous system. Cocaine binds differentially to the dopamine, serotonin, and norepinephrine transport proteins and directly prevents the re-uptake of dopamine, serotonin, and norepinephrine into pre-synaptic neurons. Its effect on dopamine levels is most responsible for the addictive property of cocaine.
The presence and function of cannabinoid CB(2) receptors in the brain have been the subjects of much debate. /The investigators/ found that systemic, intranasal or intra-accumbens local administration of JWH133, a selective CB(2) receptor agonist, dose-dependently inhibited intravenous cocaine self-administration, cocaine-enhanced locomotion, and cocaine-enhanced accumbens extracellular dopamine in wild-type and CB(1) receptor knockout (CB(1)(-/-), also known as Cnr1(-/-)) mice, but not in CB(2)(-/-) (Cnr2(-/-)) mice. This inhibition was mimicked by GW405833, another CB(2) receptor agonist with a different chemical structure, and was blocked by AM630, a selective CB(2) receptor antagonist. Intra-accumbens administration of JWH133 alone dose-dependently decreased, whereas intra-accumbens administration of AM630 elevated, extracellular dopamine and locomotion in wild-type and CB(1)(-/-) mice, but not in CB(2)(-/-) mice. Intra-accumbens administration of AM630 also blocked the reduction in cocaine self-administration and extracellular dopamine produced by systemic administration of JWH133. These findings suggest that brain CB(2) receptors modulate cocaine's rewarding and locomotor-stimulating effects, likely by a dopamine-dependent mechanism.

Cocaine has been measured in its unchanged form in sweat at 33-3579 ng/patch/30 min from heat-induced sweating; 43-3799 ng/wipe and up to 315 ng/patch during one week after nasal doses of 50-126 mg(1). Approximately 1-9% of cocaine passes through the body unchanged, 35-54% is excreted as benzoylecgonine and 32-49% is excreted as ecgonine(2).
The specific treatment of acute cocaine poisoning is the intravenous administration of a short-acting barbiturate or diazepam. Artificial respiration may be necessary. It is important to limit absorption of the drug. If entrance of the drug into circulation can be checked, and respiratory exchange maintained, the prognosis is favorable since cocaine is eliminated fairly rapidly. (L1712)
Substance abuse is a pressing problem with few therapeutic options. The identification of addiction resilience factors is a potential strategy to identify new mechanisms that can be targeted therapeutically. Heparan sulfate (HS) is a linear sulfated polysaccharide that is a component of the cell surface and extracellular matrix. Heparan sulfate modulates the activity and distribution of a set of negatively charged signaling peptides and proteins - known as the HS interactome - by acting as a co-receptor or alternative receptor for growth factors and other signaling peptides and sequestering and localizing them, among other actions. Here, we show that stimulants like cocaine and methamphetamine greatly increase HS content and sulfation levels in the lateral hypothalamus and that HS contributes to the regulation of cocaine seeking and taking. The ability of the HS-binding neuropeptide glial-cell-line-derived neurotrophic factor (GDNF) to increase cocaine intake was potentiated by a deletion that abolished its HS binding. The delivery of heparanase, the endo-beta-D-glucuronidase that degrades HS, accelerated the acquisition of cocaine self-administration and promoted persistent responding during extinction. Altogether, these results indicate that HS is a resilience factor for cocaine abuse and a novel therapeutic target for the treatment of cocaine addiction.
A common combination is heroin and cocaine ("speedball"). Users report an improved euphoria because of the combination, and there is evidence of an interaction because the partial mu opiate agonist buprenorphine reduces cocaine self-administration in animals. Cocaine reduces the signs of opiate withdrawal, and heroin may reduce the irritability seen in chronic cocaine users.
Cocaine and heroin are frequently co-abused by humans, in a combination known as speedball. Recently, chemical interactions between heroin (Her) or its metabolite morphine (Mor) and cocaine (Coc) were described, resulting in the formation of strong adducts. In this work, we evaluated whether combinations of Coc and Her affect the neurotoxicity of these drugs, using rat cortical neurons incubated with Coc, Her, Her followed by Coc (Her+Coc) and Her plus Coc (Her:Coc, 1:1). Neurons exposed to Her, Her+Coc and Her:Coc exhibited a decrease in cell viability, which was more pronounced in neurons exposed to Her and Her+Coc, in comparison with neurons exposed to the mixture (Her:Coc). Cells exposed to the mixture showed increased intracellular calcium and mitochondrial dysfunction, as determined by a decrease in intracellular ATP levels and in mitochondrial membrane potential, displaying both apoptotic and necrotic characteristics. Conversely, a major increase in cytochrome c release, caspase 3-dependent apoptosis, and decreased metabolic neuronal viability were observed upon sequential exposure to Her and Coc. The data show that drug combinations potentiate cortical neurotoxicity and that the mode of co-exposure changes cellular death pathways activated by the drugs, strongly suggesting that chemical interactions occurring in Her:Coc, such as adduct formation, shift cell death mechanisms towards necrosis. Since impairment of the prefrontal cortex is involved in the loss of impulse control observed in drug addicts, the data presented here may contribute to explain the increase in treatment failure observed in speedball abusers.
... Reserpine, dopamine, tricyclic antidepressants, alpha-methyldopa, guanethidine, and monoamine oxidase inhibitors potentiate the adverse effects of cocaine.

Cocaine has many serious medical consequences including cardiac arrhythmias, coronary artery spasm and myocardial infarction, cerebrovascular accidents, subarachnoid hemorrhage, seizures, hallucinations, intestinal ischemia, renal infarction, rhabdomyolysis and acute liver injury. Cocaine is a not infrequent cause of sudden “unexplained” death in young adults. Hepatotoxicity usually arises hours to a few days after an acute overdose, generally following or accompanying other major organ involvement. The clinical phenotype of cocaine hepatototoxicity is usually acute hepatic necrosis. Initially, serum aminotransferase and LDH levels are markedly elevated with minimal increase in alkaline phosphatase. The prothrombin time becomes abnormal rapidly and may also reflect disseminated intravascular coagulation (DIC). The serum bilirubin begins to rise after 2 to 3 days. Immunoallergic features and autoantibodies are usually absent. Liver histology usually shows centrolobular (zone 3) necrosis and fatty change, features that resemble ischemic hepatitis or liver injury due to hyperthermia, factors that may partially mediate the hepatotoxic effects of cocaine. In self-limited cases, recovery is rapid and serum aminotransferase levels usually return to normal within 1 to 2 weeks.
TERRESTRIAL FATE: Based on a classification scheme(1), a log Koc value of 2.78(2), indicates that cocaine is expected to have low mobility in soil(SRC). The pKa of cocaine is 8.61(3), indicating that this compound will exist partially in cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of the cation from moist soil is not expected because cations do not volatilize(SRC). Volatilization of neutral cocaine from moist soil surfaces is not expected(SRC) given an estimated Henry's Law constant of 4.2X10-11 atm-cu m/mole(SRC), based upon its vapor pressure, 1.91X10-7 mm Hg(5), and water solubility, 1800 mg/L(6). Cocaine is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(5). Biodegradation data in soil were not available(SRC, 2017).
AQUATIC FATE: Based on a classification scheme(1), a log Koc value of 2.78(2), indicates that cocaine is expected to adsorb to suspended solids and sediment(SRC). The pKa of cocaine is 8.61 at 15 °C(3), indicating that this compound will exist partially in the in the cation form at pH values of 5 to 9 and, therefore, volatilization from water surfaces of the cation is not expected(SRC). Volatilization from water surfaces of neutral cocaine is not expected(4) based upon an estimated Henry's Law constant of 4.2X10-11 atm-cu m/mole(SRC), derived from its vapor pressure, 1.91X10-7 mm Hg(5), and water solubility, 1800 mg/L(6). Cocaine is not expected to undergo hydrolysis in the environment and has estimated hydrolysis half-lives of 55 and 5.5 years at pH values of 7 and 8, respectively(7). According to a classification scheme(8), an estimated BCF of 15(SRC), from its log Kow of 2.30(9) and a regression-derived equation(10), suggests the potential for bioconcentration in aquatic organisms is low. Biodegradation data in water were not available(SRC, 2017).
ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), cocaine, which has a vapor pressure of 1.91X10-7 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase cocaine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 7.3 hours(SRC), calculated from its rate constant of 5.3X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase cocaine may be removed from the air by wet or dry deposition(SRC). Cocaine does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).
IDENTIFICATION AND USE: Cocaine is a semi-synthetic drug obtained from ecgonine, a product of the saponification of coca alkaloids. Cocaine freebase and cocaine hydrochloride are white solid crystals. Street cocaine used by addicts can be mixed with amphetamines, anti-histamines, benzocaine, inositol, lactose, lidocaine, mannitol, opioids, phencyclidine, procaine, sugars, tetracaine, and sometimes arsenic, caffeine, quinidine, and even flour or talc. Cocaine hydrochloride has a very limited use for anesthesia. Cocaine is Schedule II Controlled Substance. HUMAN STUDIES: The target organs are central nervous system (CNS) and the cardio-vascular system. Abuse of cocaine leads to strong psychological dependence. In low doses acute intoxication causes euphoria and agitation. Larger doses cause hyperthermia, nausea, vomiting, abdominal pain, chest pain, tachycardia, ventricular arrhythmia, hypertension, extreme anxiety, agitation, hallucination, and mydriasis. These can be followed by CNS depression with irregular respirations, convulsions, coma, cardiac disturbances, collapse and death. Chronic intoxication produces euphoria, agitation psychomotor, suicidal ideation, anorexia, weight loss, hallucinations and mental deterioration. A withdrawal syndrome with severe psychiatric effects can occur (euphoria, depression). Cocaine causes hyperthermia as a result of two mechanisms: the increase in muscular activity and a direct effect on thermal regulatory centers. The visceral effects on liver and kidney are due to dopaminergic action of cocaine, or its metabolites, or to impurities. The abrupt increase intra-alveolar pressure can cause alveolar rupture and pneumomediastinum. Rhabdomyolysis occurs as a result of several different mechanisms: direct effect on muscle and muscle metabolism, tissue ischemia, the effects of drugs taken with cocaine, such as alcohol and heroin. The principle effects of cocaine are the result of its sympathetic action: cocaine prevents the re-uptake of dopamine and noradrenaline, which accumulate and stimulate neuronal receptors. At the same time, the release of serotonin a sedative neurotransmitter, is inhibited. There may also be a direct effect on peripheral organs. Applied locally, cocaine blocks neuronal transmission: this results in a powerful local anesthetic action at the level of sensory nerve terminals. A recent meta-analysis shows an increase in congenital malformation rate in the offspring of cocaine-users, particularly for abnormalities of the limbs, the genito-urinary tract, and the cardiovascular, neurological, and digestive systems. Patients with choline esterase deficiency may develop severe reactions. ANIMAL STUDIES: Rats given a moderate dose of cocaine show increased locomotor activity and stereotypic behavior. These behaviors are thought to be mediated by the mesolimbic and nigrostriatal dopamine pathways, respectively. In rats exposed to continuous cocaine, persistent changes in acetylcholine and GABA receptors in the caudate were observed 30 days after removal of cocaine pellets, suggesting that they were long lasting or permanent. In contrast to continuous cocaine infusion, daily injections of 20 mg of cocaine for 5 days failed to produce neurodegeneration but did result in behavioral sensitization. Studies with animals demonstrate that cocaine is three times as lethal as heroin. Ninety percent of animals with free access to cocaine are dead in three months, while only 30% of those with free access to heroin are dead in the same amount of time. Monkeys with unlimited access to cocaine will choose it over food until they starve. Cocaine-induced hepatotoxicity was encountered while studying sensitization to the stimulant effects of cocaine. The surface of livers from mice that had received four or five daily injections of 20 mg/kg cocaine had an unusual pitted or roughened appearance. It was found that a single injection of 50 mg/kg cocaine could produce severe fatty necrosis of the liver. Cocaine caused a 36% drop in fetal oxygen partial pressure following a 2 mg/kg dose of cocaine to the ewe, simultaneously, it caused a 25% rise in fetal blood pressure. ECOTOXICITY STUDIES: Cyto-genotoxic effects were evidenced in mussels exposed to crack cocaine concentrations ranging from 5 to 500 ug/L. Exposure to cocaine and its metabolites significantly altered the protein profile of zebrafish embryos, modulating the expression of diverse proteins belonging to different functional classes, including cytoskeleton, eye constituents, lipid transport, lipid and energy metabolism, and stress response. Expression of vitellogenins and crystallins was modulated by cocaine and its main metabolites.
/AQUATIC SPECIES/ Our study aimed to evaluate crack cocaine effects in different life stages of the marine mussel Perna perna. For this purpose, fertilization rate, embryo-larval development, lysosomal membrane stability and DNA strand breaks were assessed. Effect concentrations in gametes and in larval development were found after 1h (IC50=23.53 mg/L) and 48h (IC50=16.31 mg/L), respectively. The highest tested concentration showing no acute toxicity (NOEC) was 10 mg/L, while the lowest observed effect concentration (LOEC) was 20 mg/L. NOEC concerning embryo-larval development was 0.625 mg/L, while the LOEC was 1.25 mg/L. Cyto-genotoxic effects were evidenced in mussels exposed to crack cocaine concentrations ranging from 5 to 500 ug/L. Our results report the first data on effects of an illicit drug to marine organisms and should encourage further ecotoxicological studies of these contaminants of emerging concern in coastal ecosystems.
/AQUATIC SPECIES/ Illicit drugs have been identified as emerging aquatic pollutants because of their widespread presence in freshwaters and potential toxicity towards aquatic organisms. Among illicit drug residues, cocaine (COC) and its main metabolites, namely benzoylecgonine (BE) and ecgonine methyl ester (EME), are commonly detected in freshwaters worldwide at concentration that can induce diverse adverse effects to non-target organisms. However, the information of toxicity and mechanisms of action (MoA) of these drugs, mainly of COC metabolites, to aquatic species is still fragmentary and inadequate. Thus, this study was aimed at investigating the toxicity of two concentrations (0.3 and 1.0 ug/L) of COC, BE and EME similar to those found in aquatic ecosystems on zebrafish (Danio rerio) embryos at 96 hr post fertilization through a functional proteomics approach. Exposure to COC and both its metabolites significantly altered the protein profile of zebrafish embryos, modulating the expression of diverse proteins belonging to different functional classes, including cytoskeleton, eye constituents, lipid transport, lipid and energy metabolism, and stress response. Expression of vitellogenins and crystallins was modulated by COC and both its main metabolites, while only BE and EME altered proteins related to lipid and energy metabolism, as well as to oxidative stress response. Our data confirmed the potential toxicity of low concentrations of COC, BE and EME, and helped to shed light on their MoA on an aquatic vertebrate during early developmental period.

Cocaine hydrochloride is a local anesthetic which blocks initiation or conduction of nerve impulses following local application; when applied topically to mucous membranes, the drug also produces intense vasoconstriction. When applied topically to the mucous membranes of the nose or mouth, cocaine reduces the acuity of smell or taste, respectively. Cocaine exerts an indirect adrenergic effect by interfering with the uptake of norepinephrine by adrenergic nerve terminals, and therefore potentiates the effects of catecholamines. The indirect adrenergic effect is apparently the mechanism by which the drug produces vasoconstriction and mydriasis. Cocaine has CNS stimulating effects. The drug is also markedly pyrogenic, augmenting heat production by stimulating muscular activity and decreasing heat loss through vasoconstriction.
Cocaine has multiple central and peripheral pharmacological actions. The action responsible for the rewarding property, and hence the abuse liability, of cocaine is an action in the dopaminergic synapse; in the rat the major set of critical dopaminergic synapses appears to be in the nucleus accumbens. Cocaine prolongs the activity of dopamine in the synapse by blocking the dopamine reuptake mechanism (which usually inactivates the transmitter by removing it from the proximity of its synaptic targets). This is an action shared with amphetamine; in addition to blocking the dopamine reuptake mechanism, amphetamine also augments dopaminergic function by augmenting dopamine release directly into the synapse. While amphetamine and cocaine have discriminable subjective effects, perhaps due to differences in rate of onset and metabolism or perhaps due to different side effects, cocaine shares its rewarding impact and abuse liability very closely with amphetamine. When drug access is unlimited, cocaine and amphetamine have the same ability to dominate behavior, reducing other behaviors such as feeding and sleeping and, in the process, reducing stress resistance to life threatening levels.
Cocaine is a potent inhibitor of dopamine reuptake and appears to release this neurotransmiter. Dopamine reuptake inhibition has been confirmed in a number of studies and is consistent with acutely increased dopamine neurotransmission. A further reflection of increased synaptic availability of dopamine is the finding of elevated 3-methoxytyramine but normal homovanillic acid concentrations after cocaine administration. Cocaine also causes reductions in brain dopamine concentrations with repeated administration. Cocaine elevates brain dopamine concentrations acutely, followed by reductions below normal levels several minutes later. Cocaine has also been shown to inhibit dopamine vesicle binding, thereby exposing /dopamine/ to intracellular metabolism.

The observed half life depends on the route of administration, dosage, and individual subject. It is of the order of 0.7 to 1.5 hours. After oral administration, it appears to be 0.8 hours, nasal administration, 1.25 hours, parenteral administration 0.7 to 0.9 hours.
Benzoylecgonine and ecgonine methyl ester, the major metabolites of cocaine, have half lives of 5-8 hours and 3.5-6 hours, respectively. /Cocaine metabolites/
The half-life is a very important parameter for estimating the time required to eliminate the drug in the body. It takes one half-life for plasma levels to fall to half of their original level. In the case of cocaine, it takes 1.5 hr for cocaine plasma levels to fall from 102 ng/mL. This is the same time that it takes for concentrations to fall from 51 ng/mL to 25.5 ng/mL. By five half-lives (7.5 hr) the plasma concentration of cocaine decreased from 102 ng/mL to 3.1 ng/mL, which is 3% of the original drug in the body. Almost all the drug (97%) will be eliminated by five half-lives. For reaching a certain drug level, an additional half-life will be required if the dose is doubled. For example, if cocaine is given at a dose of 40 mg, it will take two half-lives to reach the level of 51 ng/mL and six half-lives to reach the level of 3.1 ng/mL.
The biological half-life of cocaine is 0.5 to 1.5 hours.

Hepatic. Cocaine is metabolized to benzoylecgonine and ecgonine methyl ester, which are both excreted in the urine. In the presence of alcohol, a further active metabolite, cocaethylene is formed, and is more toxic then cocaine itself.
The metabolism of cocaine is complex and dependent on both genetic and acquired factors. Three major pathways of cocaine metabolism are well described. Cocaine undergoes N-demethylation in the liver to form norcocaine, a minor metabolite that rarely accounts for more than 5% of drug. However, norcocaine readily crosses the blood-brain barrier and produces clinical effects in animals that are quite similar to cocaine. Nearly half of a dose of cocaine is both nonenzymatically and enzymatically hydrolyzed to form benzoylecgonine (BE). the BE is inject into animals, some reports suggest that it is virtually inactive, while other studies demonstrate cerebral vasoconstriction and seizures. When with injected directly into the cerebral ventricles or applied to the surface of cerebral arteries, BE is a potent vasoconstrictor. Although BE tranverses the blood-brain barrier poorly, the potential effects ar of concern as some BE is probably formed form cocaine that has already entered the central nervous system (CNS). In vitro, BE has little or not effect on cardia sodium or potassium channels. Finally, plasma cholinesterase (PChE) and other esterases metabolize cocaine to ecgonine methyl ester (EME). In normal individuals, between 32% and 49% of cocaine is metabolized to EME. Like BE, EME crosses the blood-brain barrier poorly. Although many authors state that EME has little or no pharmacologic activity, diverse animal models demonstrate contradictory results, concluding that EME is a vasodilator, sedative, anticonvulsant, and protective metabolite against lethal doses of cocaine.
1 to 9% of cocaine is eliminated unchanged in the urine, with a higher proportion in acid urine. The metabolites ecgonine methyl ester, benzoylecgonine, and ecgonine are recovered in variable proportions which depend on the route of administration. At the end of 4 hours, most of the drug is eliminated from plasma, but metabolites may be identified up to 144 hours after administration. Unchanged cocaine is excreted in the stool and in saliva. Cocaine and benzoylecgonine can be detected in maternal milk up to 36 hours after administration, and in the urine of neonates for as much as 5 days.Freebase cocaine crosses the placenta, and norcocaine persists for 4 to 5 days in amniotic fluid, even when it is no longer detectable in maternal blood.
Cocaine metabolism takes place mainly in the liver, within 2 hours of administration. The rate of metabolism varies according to plasma concentration. There are 3 routes of bio-transformation: the major route is hydrolysis of cocaine by hepatic and plasma esterases, with loss of a benzoyl group to give ecgonine methyl ester. Esterase activity varies substantially from one subject to another. The secondary route is spontaneous hydrolysis, probably non-enzymatic, which leads to benzoylecgonine by demethylation. The final degradation of cocaine, which is a sequel to both the principle and secondary routes of metabolism, leads to ecgonine. N-demethylation of cocaine is a minor route leading to norcocaine. The principle metabolites are therefore benzoylecgonine, ecgonine methyl ester, and ecgonine itself, which are inactive; and norcocaine which is active, and may be relevant after acute intoxication. In the presence of alcohol, a further active metabolite, cocaethylene is formed, and is more toxic then cocaine itself. ...
Cocaine is hydrolyzed rapidly by liver and plasma esterases to ecgonine methyl ester, which accounts for 30% to 50% of of the parent product. Nonenzymatic hydrolysis result in the formation of the other major metabolite, benzoylecgonine (approximately 40% of the parent product). Minor metabolites, norcocaine, and ecgonine account for the other degradation products.
Hepatic. Cocaine is metabolized to benzoylecgonine and ecgonine methyl ester, which are both excreted in the urine. In the presence of alcohol, a further active metabolite, cocaethylene is formed, and is more toxic then cocaine itself. Half Life: 1 hour
Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate.
Drugs used to cause constriction of the blood vessels.
Drugs that block the transport of DOPAMINE into axon terminals or into storage vesicles within terminals. Most of the ADRENERGIC UPTAKE INHIBITORS also inhibit dopamine uptake.
Cocaine is absorbed from all sites of application, including mucous membranes and gastrointestinal mucosa. By oral or intra-nasal route, 60 to 80% of cocaine is absorbed.
Cocaine hydrochloride is absorbed from all sites of application, including mucous membranes and GI mucosa, and absorption may be enhanced in the presence of inflammation. In recreational cocaine users, the relative bioavailability of the drug, as determined by area under the plasma concentration-time curve (AUC), for a 2-mg/kg intranasal or oral dose of a 10% cocaine solution is the same; however, peak plasma concentrations are reportedly higher and occur sooner following oral administration than after intranasal administration. Following topical application of a 10% solution to the nasal mucosa, peak plasma cocaine concentrations occur within 15-120 minutes. Following topical application of cocaine hydrochloride solutions to mucous membranes, the onset of local anesthesia occurs within about 1 minute, is maximal within about 5 minutes, and may persist for 30 minutes or longer, depending on the dose and concentration used. /Cocaine hydrochloride/
Cocaine is rapidly and well absorbed from the nasal mucosa, gastrointestinal mucosa, pulmonary alveoli and by direct intravenous injection ... .
Cocaine is absorbed by all routes of administration, but the proportion absorbed depends on the route. After oral administration, cocaine appears in blood after about 30 minutes, reaching a maximum concentration in 50 to 90 minutes. In acid medium, cocaine is ionized, and fails to cross into cells. In alkaline medium, there is less ionization and the absorption rapidly increases. By the nasal route, clinical effects are evident 3 minutes after administration, and last for 30 to 60 minutes, the peak plasma concentration being around 15 minutes. By oral or intra-nasal route, 60 to 80% of cocaine is absorbed. By inhalation, the absorption can vary from 20 to 60%, the variability being related to secondary vasoconstriction. Freebase does not undergo first-pass hepatic metabolism, and plasma concentrations rise immediately to 1 to 2 mg/L. The effects on the brain occur very rapidly, after about 8 to 12 seconds, are very violent ("flash"), and last only 5 to 10 minutes. By the intravenous route blood concentrations rise to a peak within a few minutes.
When smoked, absorption of the free base from the lung is rapid and efficient, producing concn in plasma of more than 900 ng/mL; peak values of 150 to 200 ng/mL are reached 30 to 40 minutes after the inhalation of 96 mg of crystalline cocaine hydrochloride.

MEDICATION
Cocaine (KOE-kane) is a local anesthetic. It is applied to certain areas of the body (for example, the nose, mouth, or throat) to cause loss of feeling. This allows some kinds of examinations or surgery to be done without causing pain. (L1505)
The purity of crack is generally higher, but depends not only on the purity of the cocaine used in its manufacture, but also on the method of production. Common adulterants of cocaine are phenacetin, lignocaine, benzocaine, procaine, caffeine, paracetamol and sugars. Some of these may be removed in the production of crack. Occasionally, unusual additives have been reported, such as atropine, diltiazem and other pharmaceutical substances. The free base constitutes 89% of the hydrochloride salt.
... The National Household Survey in 1992 indicated that approximately 22.6 million people have tried cocaine, five million within the last year before the survey (down from 12 million in 1985 and 8 million in 1988), and 1.3 million used it at least once within the month before the survey. ... The number of people who have used cocaine in the last 30 days /was/ 5.8 million in 1985 and 1.6 million in 1990 to 1.3 million in 1992. ... The number of people using cocaine on a daily or weekly basis is rising. Of the current three million regular users, about 500,000 use crack (freebase cocaine).
... Most addicts are male, under the age of 40, and use multiple drugs (75%). ... Eighty-four percent of persons diagnosed with cocaine dependence also met the criteria for alcohol dependence. A history of marijuana use was reported by 98% of cocaine addicts.

Crack is manufactured from cocaine hydrochloride by one of two main methods: either microwaving a wet mixture with sodium bicarbonate or by adding alkali to a hot saturated solution of cocaine and allowing the denser base to settle and solidify.
Free base is made by dissolving cocaine salt in an aqueous alkaline solution and then extracting the free base form with a solvent such as ether.
Dried coca leaves contain up to 1% cocaine. They are processed into cocaine hydrochloride in clandestine laboratories. The leaves are moistened with lime water or other alkali and extracted with kerosene (paraffin). The dissolved cocaine is extracted from the kerosene with sulfuric acid to produce an aqueous solution of cocaine sulfate. This solution is neutralised with lime, causing cocaine base (coca paste) to precipitate. Coca paste is redissolved in sulfuric acid and potassium permanganate is added to destroy cinnamoylcocaine and other impurities. The filtered solution is again treated with alkali to precipitate the free base, which is dissolved in acetone or other solvents. Concentrated hydrochloric acid is added to the solution, causing cocaine hydrochloride to settle out as a solid residue.
Extracted from the leaves of several South American shrubs of the genus Erythroxylon, especially E. coca.
Topical, solution 4% Cocaine Hydrochloride Topical Solution (C-II); 10% Cocaine Hydrochloride Topical Solution (C-II). /Cocaine hydrochloride/
Common street names include: Coca, Coke, Crack, Flake, Snow, and Soda Cot.
Cocaine is usually distributed as a white, crystalline powder. Cocaine is often diluted ("cut") with a variety of substances, the most common of which are sugars and local anesthetics. It is "cut" to stretch the amount of the product and increase profits for dealers. In contrast, cocaine base (crack) looks like small, irregularly shaped chunks (or "rocks") of a whitish solid.
Cocaine purchased on the street may contain adulterant drugs such as lidocaine or benzocaine or stimulants such as caffeine, methamphetamine, ephedrine, and phencyclidine. Most illicit cocaine in the United States is adulterated with levamisole, an antiparasitic drug that can cause agranulocytosis.

The cocaine manufacturing process takes place in remote jungle labs where the raw product undergoes a series of chemical transformations. Colombia produces about 90 percent of the cocaine powder reaching the United States. Most of the cocaine entering the United States comes through Mexico.
Crack is cocaine hydrochloride powder that has been processed to form a rock crystal that is then usually smoked.
Cocaine is one of at least 14 alkaloids extracted from the leaves of two coca shrubs indigenous to South America. ... The small leaves (5 cm) /of Erythroxylum coca/, which contain between 0.5% & 2.0% (avg 1%) cocaine, are harvested in March, June, & November. This plant is the main source of illicit cocaine trade. The leaves are soaked in gasoline drums containing alkali, sulfuric acid, kerosene, & other solvents. Later, the fluid & leaves are discarded, leaving a thick brown paste (coca paste) which is sold to clandestine laboratories. There the paste is refined into white crystalline powder containing cocaine hydrochloride.
Sterile oily solutions are prepared aseptically. In the preparation of oily solutions of cocaine only a mild degree of heat should be used.

Cocaine produces anesthesia by inhibiting excitation of nerve endings or by blocking conduction in peripheral nerves. This is achieved by reversibly binding to and inactivating sodium channels. Sodium influx through these channels is necessary for the depolarization of nerve cell membranes and subsequent propagation of impulses along the course of the nerve. Cocaine is the only local anesthetic with vasoconstrictive properties. This is a result of its blockade of norepinephrine reuptake in the autonomic nervous system. Cocaine binds differentially to the dopamine, serotonin, and norepinephrine transport proteins and directly prevents the re-uptake of dopamine, serotonin, and norepinephrine into pre-synaptic neurons. Its effect on dopamine levels is most responsible for the addictive property of cocaine.
