    • HOW IS COCAINE USED? Cocaine can be snorted, injected, smoked or eaten. The level and length of the effects depend on how the drug was induce ONSET DURATIONSNORTED 1 MINUTE 20-40 MININJECTED 1-5 SECONDS 15-20 MINSMOKED IMMIDIATE 5-15 MIN
    • EPIDEMIOLOGYRESEARCH BY US IN 2005:1)FREQUENCY: According to the National Survey on Drug Use & Health (NSDUH) for the age group 12 years and older Approximately 33.7 million Americans have tried cocaine at least once in their lifetimes, representing 13.8% of the 12 years and older population2)Mortality/morbidity: On average, cocaine alone or in combination with other drugs was reported in 39% of drug misuse deaths
    • 3)RACE: more common in whites then africans.4)Sex: the 2005 National Youth Risk Behavior Survey, 8.4% of males and 6.8% of females had used cocaine at least once in 2005.5)AGE:19 to 28 age
    • Common S/S of Cocaine• Decreased Appetite• Increased Body Temperature• Increased Heart Rate• Dilated Pupils• Nausea/Vomiting
    • • Severe Nose Damage (when snorted)• Violent Behavior• Kidney Failure• Seizure and/or Stroke• Heart Attack
    • • Increased Alertness• Decreased Fatigue• Increased Concentration• Insomnia• Increased Irritability• Increased Psychosis
    • • Confused Behavior• Increased Fear• Extreme Paranoia• Severe Anxiety Attacks• Hallucinations (in extreme cases)• Aggressive Behavior
    • ADDICTION AND WITHDRAWAL EFFETCTS• Those who use cocaine heavily or regularly find it extremely difficult to stop and often suffer through serious withdrawal symptoms such as:• Severe Irritability• Chronic Depression• Excessive Sleep• Eating Disorders• Nausea / Vomiting• Diarrhea• Heart Attack• Paranoia• Loss of Sex Drive• Insomnia
    • Mechanism Of Action Of CocaineCNS:*It blocks reupake ofneurotransmissioninto presynaptic vesiclaes(esp DA receptor DAT) Euphoria
    • CNS continued..*Nicotine inc the level of DA in brainin chain smoking*Prolonged exposure down regulation of DA depression
    • CNS…*prolonged exposureactivation of reward centre addiction
    • PNS*Block of NE transporter sympathomimetic syndromeTachycardia,HTN,tachypnea,mydriasis,sssdiaphoresis and agitation
    • PNS CONTINUED…• Blocking of Na +channels,interfere with AP Local anesthesia + in heat it will leads to type 1 antidysrythematic activity and more over leads to prolong QRS complex
    • DSM-IV-TR• DSM-IV-TR describes 10 cocaine induced psychiatric disorders and gives codes to them are as follows;305.60 Abuse304.20 Dependence292.89 -Induced anxiety disorder292.84 -Induced mood disorder292.11 -Induced psychotic disorder, with delusions292.12 -Induced psychotic disorder, with hallucinations292.89 -Induced sexual dysfunction292.89 -Induced sleep disorder292.89 Intoxication292.81 Intoxication delirium292.9 -Related disorder NOS292.0 Withdrawal
    • 1)COCAINE INTOXICATION: Diagnosed when the patient must have used cocaine recently and must have developed clinically significant behavioral or psychological changes. Features:a) Euphoriab) Talkativenessc) Grandiosityd) Anxietye) impaired judgmentf) Angerg) Impaired judgment
    • Signs and symptoms:1)Tachycardia or bradycardia2)Mydriasis3)Perspiration4)Nausea or vomiting5)Weight loss6)Weakness, respiratory depression, chest pain, or dysrhythmia7)Disorientation, seizures, dyskinesias, dystonias, or coma8)Mental state examination shows irritability, impaired attention and poor judgment
    • 2)COCAINE WITHDRAWAL Diagnostic criteria: include cessation or reduction in previously heavy or prolonged cocaine use.The patient also must have a dysphoric mood associated with 2 of the following 5 physiological changes which are;1) Fatigue2) Unpleasant dreams3) isomnia/hypersomnia4) Inc appetite Mental health exam: may show a sleepy, slowed-down patient who complains of depressed mood and has a restricted affect. They may express suicidal ideation.
    • 3)COCAINE INTOXICATION DELIRIUM Diagnostic criteria:include both a disturbance in consciousness resulting in a reduction of the patients ability to focus, sustain, or shift attention and a change in cognition. These changes must develop over a short period and fluctuate in severity Mental health exam: shows*patient is distractible and confused with a variable affect and mood.*Visual illusions may also be present.*Judgment is extremely poor, as is orientation.* suicidal and homicidal ideation may not be present.
    • 4)COCAINE INDUCED PSYCHOTIC DISORDERS+DELUSIONS Diagnostic Criteria: include prominent delusions developing during or within a month of cocaine intoxication or withdrawal.• Presenting features:psychosis,communication and interaction gap with others, inability to recognize and accept reality.• Mental state exam:shows *tense patientwho appear fearful or anxious. *They may be suspicious of questions asked. *Impaired judgement *may think for homicidal or suicidal acts
    • 5)Cocaine Induced Psychotic Disorders + Halucinations The diagnostic criteria :prominenthallucinations developing during or within amonth of cocaine intoxication or withdrawal. Mental status examination: shows* a patient who is distracted by internalstimuli, may show thought blocking (verbaloutflow is stopped mid thought by internalstimuli)*Attention is variable*homicidal and suicidal ideation may be present.
    • 6)Cocaine Induced Mood Disorders diagnostic criteria: a prominent and persistent disturbance inmood that arises only in association with the abuse of cocaine mustoccur. The symptoms must develop during or within 1 month of cocaineuse, and the use of cocaine closely corresponds to these symptoms. presenting features:depressed mood,dec interest in dailyactivities,apathy,wt changes,fatigue,excessive guilt,feeling ofworthlessness Mental state exam: shows*depressed mood with restricted or flat affect,*depressed mood with slowed movements and responses*reduced concentration and suicidal ideation*Orientation is intact.

    • LAB INVESTIGATION1) CBC:for anemia,leukocytosis,leukopenia2) Electrolytes:hypokalemia because acute intoicaion shift intracellular k+ severe condition hyperkalemia may occur->cardiac arrythmia.3) Renal function test:check for rhabdomyolysis and renal artery thrombosis has been reported for te use of cocaine
    • LAB INVESTIGATION4)Serum bicarbonate levels: dec5)Urine analysis: to check myoglobin dur to rhabdomyolysis6)Glucose: should be checked in every patirent having altered consciousness due o hypoglycemia7)Creatine kinase: for rhabdomyolysis
    • LAB INVESTIGATION8)Plasma cocaine levels9)Cardiac enzymes10)LFTs:heaptic damage occus after acute intoxication of cocaine + patients who take cocaine are at the high risk of developing infectious hepatitis.11)Urine drug screen:to detect benzoylegonine which is a metabolite of cocaine excreat in urine for 60 hours after first dose of cocaine.
    • LAB INVESTIGATION12) Imaging studies:*CXR: for pulmonary signs of cocaine like Pneumomediastinum, pneumothorax, pneumoni a, pulmonary embolism, atelectasis*head CT scan:Patients exhibiting acute mental status changes or focal neurological signs and symptoms may require a head CT scan. Cocaine use has been associated with intracranial bleeding and embolic and thrombotic strokes.13)EKG :for dysrhythmia
    • TREATMENT:• Establish the patients airway, breathing, and circulation (ABCs)• Ensure adequate ventilation if patient is unconscious.• provide oxygen• frequently check vital signs• monitor glucose levels for patients with altered mental status; carefully use naloxone for patients with altered mental status.• Benzodiazepines are the drugs of choice for the management of patients with agitation, seizures, tachycardia, and hypertension.
    • TREATMENT• If the condition persist specific antihypertensive therapy (e.g., intravenous nitrates or calcium- channel blockers) can be given.• If the patient is volume depleted this is corrected with intravenous isotonic saline.• Patients should be continued to be observed until they have normal vital signs and mental status.• Manage the temperature
    • TREATMENT• Manage Cardiac arrhythmias; *ventricular tachycardiaequires immediate defibrillation. *wide –complex tachycardias can be treated withsodium bicarbonate
