Toxicity Chemistry Cocaine benzoylmethyl ecgonine is the psychoactive alkaloid of the coca plant Erythroxylon coca. Cocaine is the only naturally occurring local anaesthetic.
Drug Interactions Disulfiram Published literature reported that disulfiram treatment increased plasma cocaine exposure, including both AUC and Cmax, by Life of cocaine fold after acute intranasal cocaine administration. Other literature reported that co-administration of disulfiram increased AUC of plasma cocaine by several fold after intravenous cocaine administration [see Clinical Pharmacology Consider using other local anesthetic agents.
Epinephrine, Phenylephrine There are reports in the published literature of myocardial ischemia, myocardial infarction, and ventricular arrhythmias after concomitant administration of topical intranasal cocaine with epinephrine and phenylephrine during nasal and sinus surgery. If concomitant use is unavoidable, prolonged vital sign and ECG monitoring may be required [see Warnings and Precautions 5.
Inhibitors of plasma cholinesterase pseudocholinesterase Cocaine has been described in literature to be primarily metabolized and inactivated by nonenzymatic ester hydrolysis and hepatic carboxylesterase, and also by plasma cholinesterase, hepatic carboxylesterase, and CYP3A4 [see Clinical Pharmacology Plasma cholinesterase activity may be decreased by chronic administration of certain monoamine oxidase inhibitors, oral contraceptives, or glucocorticoids.
It may also be diminished by administration of irreversible plasma cholinesterase inhibitors such as echothiophate, organophosphate insecticides, and certain antineoplastic agents.
Since cocaine is metabolized by multiple enzymes, the effect of reduced plasma cholinesterase activity on cocaine exposure may be limited. Monitor patients with reduced plasma cholinesterase activity for adverse reactions such as headache, epistaxis, and clinically-relevant increases in heart rate or blood pressure.
In published animal reproduction studies, cocaine administered to pregnant females during the gestational period produced cryptorchidism, hydronephrosis, hemorrhage, hydrocephalus, cleft palate, delayed ossification, and limb anomalies in mice at 1.
Single dose administration of cocaine intravenously during organogenesis in mice produced cryptorchidism, anophthalmia, exencephaly, and delayed ossification at 1. In rats, a single dose of cocaine administered by intraperitoneal injection produced edematous fetuses, hemorrhages and limb defects at 6.
Based on animal data, advise pregnant women of the potential risk to a fetus. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. Data Human Data There are no available data on the use of intranasal cocaine hydrochloride solution in pregnant women to inform a drug-associated risk adverse developmental outcomes.
There are published data describing adverse developmental outcomes in women with chronic cocaine abuse during pregnancy. The published case-control and observational studies examining the effect of in utero cocaine exposure on fetal growth parameters, after controlling for confounding variables, found exposure was associated with reduced fetal growth compared with non-drug-abuse populations.
Published data from a large number of studies of women with chronic cocaine abuse during pregnancy are inconsistent in their findings with regard to other developmental outcomes. Prospective studies controlling for polydrug use marijuana, alcohol, tobacco and lifestyle factors, have not demonstrated any association between cocaine abuse and specific major or minor fetal anomalies or other forms of fetal harm premature birth, stillbirth, miscarriage, low birth weight, reduced head circumference, or placental abruption.
The applicability of the findings from these studies of chronic abuse in pregnancy to a single topical exposure is limited. Animal Data Formal animal reproduction and development studies have not been conducted with intranasal cocaine hydrochloride.
However, reproduction and development studies with cocaine have been reported in the published literature.
No maternal toxicity was observed. No evidence of maternal toxicity was noted.
In addition, visceral malformations that included limb anomalies, cerebral and intra-abdominal hemorrhage were observed at this dose. No significant maternal toxicity was noted at this dose. Fetal edema and hemorrhage were observed in cocaine-treated litters at 10 times the HRD and microencephaly at 15 times the HRD.
In published rat studies, prenatal cocaine administration produced hypoactivity in the pups and abnormal open field activity 5 times the HRD and deficits in associational learning 6.Cocaine and Metabolites Urinary Excretion after Controlled Smoked Administration * Cocaine is the second most prevalent drug of abuse in the United States and is a required analyte for the U.S.
Substance Abuse Mental Health Services Administration’s given the one-hour elimination half-life of cocaine. COCAINE HYDROCHLORIDE nasal solution is indicated for the induction of local anesthesia of the mucous membranes when performing diagnostic procedures and .
Cocaine takes effect quickly, but has a short half-life, meaning that the high is generally short-lived—lasting from minutes, depending on how the drug is used and how quickly the drug is absorbed into the bloodstream, Psychology Today publishes. The presence of cocaine, or its major metabolite, benzoylecgonine, indicates use within the past 4 days. Cocaine has a 6-hour half-life, so it will be present in urine for 1 day after last use. Benzoylecgonine has a half-life of 12 hours, so it will be detected in urine up to 4 days after last use. Dec 09, · There are a lot of people that are addicted to crack or powdered cocaine in British Columbia. Not many people can actually just casually use crack cocaine.

Dec 15, · Cocaine, coke, blow or snow – whatever you call it, have you ever wondered how the drug is actually made and distributed? We trace cocaine from coca leaf in . Although cocaine has a short half-life, elimination half-lives of cocaine metabolites are substantially longer (Jufer et al., ).
Mar 24, · Welcome!! ~ Feel free to Like & Subscribe ~ - Cocaine, also known as coke, is a strong stimulant mostly used as a recreational drug. It is commonly snorted, inhaled, or injected into the veins. With repeated exposure to cocaine, the brain starts to adapt so that the reward pathway becomes less sensitive to natural reinforcers10,18 (see "What Are Some Ways that Cocaine Changes the Brain?"). At the same time, circuits involved in stress become increasingly sensitive, leading to increased displeasure and negative moods when not taking the drug, which are signs of withdrawal. Cocaine and Metabolites Urinary Excretion after Controlled Smoked Administration * Cocaine is the second most prevalent drug of abuse in the United States and is a required analyte for the U.S. Substance Abuse Mental Health Services Administration’s given the one-hour elimination half-life of cocaine.
The half-life of cocaine may increase after chronic dosing (J ufer et al., ; Moolchan, Cone, Wstadik, Huestis & Preston, ).
