An opioid overdose is an acute condition due to excessive use of narcotics. It should not be confused with opioid dependency. Prescription opioid overdose was responsible for more deaths in the United States from 1999-2008 than heroin or cocaine overdose combined. Heroin overdose in a number of cases, can occur accidentally in a group of people called as 'body packers' and 'body stuffers'. Body packers swallow bags of heroin, to hide them in their gastrointestinal tract. While body stuffers, usually stuff their rectum or vagina with bags of heroin in an attempt to illegally smuggle them into a country. Since these bags are not specially designed to store drug in the body, there are chances that they might actually rupture leading to accidental poisoning/overdose.
Epidemiology and Demographics
As per recent Center for disease control (CDC) data, it accounts for the largest percentage of substance abuse deaths in prescription drug category. Of the 22,134 deaths relating to prescription drug overdose in 2010, 16,651 (75%) involved opioid analgesics (also called opioid pain relievers or prescription painkillers), and 6,497 (30%) involved benzodiazepines. In the year 2011, the most commonly involved drug was cocaine, with 162.1 visits per 100,000 population. This was closely followed by marijuana, which was involved in 146.2 visits per 100,000 population. Other drugs had lower rates: heroin (83.0 visits per 100,000 population), illicit stimulants (predominately amphetamines and methamphetamine; 51.3 visits per 100,000 population), and other illicit drugs (predominately PCP and various hallucinogens; 42.1 visits per 100,000 population).
Commonly Abused Opioids
Although any opioid can by abused for recreational purposes, some of the most common ones are as follows:
For a more detailed description of one of these opioids click on the name.
Opioid overdoses associated with a conjunction of benzodiazepines or alcohol use leads to a contraindicated condition wherein higher instances of general negative overdose traits native to the overdose profile of opioid use alone but to a much greater extent. Other CNS depressants, or "downers", muscle relaxers, pain relievers, anti-convulsants, anxiolytics (anti-anxiety drugs), treatment drugs of a psychoactive or epileptic variety or any other such drug with its active function meant to calm or mitigate neuronal signaling (barbiturates, etc.) can additionally cause a worsened condition with less likelihood of recovery cumulative to each added drug of a diverse or disparate hampering effect to the central or peripheral nervous system of the user. This includes drugs less immediately classed to a slowing of the metabolism such as with GABAergics like GHB or glutamatergic antagonists like PCP or Ketamine.
|Alcohol intoxication||Altered mental status without miosis and respiratory depression.|
|Sedative hypnotics||Miosis absent.|
|Phencyclidine (PCP) overdose||CNS depression and miosis are present. Nystagmus present and respiratory depression absent.|
|Ketamine overdose||CNS depression and miosis are present. Nystagmus present and respiratory depression absent.|
|Antipsychotic overdose||Hypotension and bradycardia are seen, but other features are absent.|
|Pontine hemorrhage||Miosis present, other features absent.|
|Gammahydroxybutyrate/gammabutyrolactone overdose||Most likely manifests as opioid overdose. Miosis may not be present.|
|Clonidine/imidazolines overdose||Profound bradycardia and hypotension.|
Additionally, none of these have a response to naloxone, as dramatic as in treating opioid overdose.
Mechanism of Death from Overdose
Heroin is a semisynthetic derivative of morphine, that has a high addictive potential. When used intravenously, it is even more potent. Similar to morphine and other analgesic opioids, heroin has mu, kappa, and delta receptor activity. Stimulation of the mu receptors results in analgesia, euphoria, CNS depression, respiratory depression, and miosis.
Opioids can cause respiratory depression, due to their role in reducing brains response to changes in PaCO2 levels and hypoxia. Respiratory arrest is the most common cause of death in cases of opioid overdose. The effect on respiratory depression is more potent for pure agonists such as heroin and morphine, as compared to partial agonists such as burenorphine. It can also cause a mild hypotension by reducing the sympathetic tone in blood vessels, leading to vasodilation and facial flushing. opioids have inhibitory effects on baroreceptors as well as reduces gastric motility, leading further to bradycardia and constipation respectively.
The onset of action, peak effects, and duration of action vary with the different methods of use, as well as the type of opioid used. On injecting, the onset of action is within 1-2 minutes when injected intravenous and within 15-30 minutes when injected intramuscular or snorted. Analgesic effects usually last for 3-5 hours.
Heroin is rapidly converted to 6-monoacetylmorphine (6-MAM) by the liver, brain, heart, and kidneys, which is further converted to morphine. Morphine has a longer half life as compared to heroin. However a small amount of 6-MAM is detectable in urine for a long time, which serves as the basis for its detection in toxicology screens.
Risk Factors For Abuse
Demographic factors: Being a young, single male, without a stable employment is a high risk factor for overdose.
Resuming the behavior after a period of abstinence: The abstinence could be due to voluntary efforts to stop the abuse, medically induced withdrawal or imprisonment resulting in forced abstinence.
Inconsistency with the quality of the drugs: Most commonly these are sold on streets, the quality being unpredictable & inconsistent. A higher purity sample may cause overdose at doses to which the person was used to before.
Mixing different type of drugs: Mixing drugs that have a brain and respiratory function depressing action similar to opioids, may lead to an overdose even at smaller doses. This may include drugs such as sedative-hypnotic (diazepam, clonazepam, lorazepam etc), H1 antihistaminics such as chlorpheniramine or promethazine or even alcohol. Different drugs will potentiate the effect of opioids differently. 
Physical illness or recent infections: During states of metabolic stress, especially when a person is severely ill or dehydrated, even smaller doses may cause overdose.
Past overdose events: Recent research has shown that people who have overdosed in the past are at much greater risk of future overdose.
DSM-V Diagnostic Criteria for Opioid Intoxication
Opiate overdose symptoms and signs include: decreased level of consciousness and pinpoint pupils. Heart rate and breathing slow down, sometimes to a stop. Blue lips and nails are caused by insufficient oxygen in the blood. Other symptoms include seizures and muscle spasms. A person experiencing an opiate overdose usually will not wake up even if their name is called or if they are shaken vigorously. The following list summarizes the most commonly experienced symptoms with opioid overdose.
- Airways and lungs
- No breathing
- Shallow breathing
- Slow and difficult breathing
- Eyes, ears, nose, and throat
- Dry mouth
- Miosis (Extremely small pupils 'pinpoint pupils')
- Tongue discoloration
- Heart and blood
- Low blood pressure
- Weak pulse
- Stomach and intestines
- Spasms of the stomach and intestinal tract
- Nervous system
- Renal system
Naloxone is very effective at reversing the cause, rather than just the symptoms, of an opioid overdose. A longer-acting variant is naltrexone. Naltrexone is primarily meant to treat opioid and alcohol dependence. Diprenorphine (Revivon) is similar in action to naloxone, only it is significantly stronger and is reserved for acting as an antagonist to the strongest, non-human opioids, such as carfentanyl (in fact, carfentanyl, and other opioids for usage on large animals such as elephants, often come packaged with Revivon to be used after carfentanyl is no longer needed in the animal).
Initial adult dose for patient experiencing respiratory depression is 0.04 mg IV, while the initial pediatric dose is 0.1 mg/Kg IV. If the respiratory rate doesn't increase in next 2-3 minutes a second dose of 0.5 mg is given. If further there is no increase in respiratory rate, following doses can be administered after every 2-3 minutes till an increase in respiratory rate is obtained, 2 mg, 4 mg, 10 mg, 15 mg.
Shown below is a management protocol for treating opioid overdose.
|Opioid overdose: Respiratory rate < 12/min|
|Oxygenate with bag and mask, administer naloxone with a gradually increasing dose till reversal of respiratory depression is seen|
|History of use of morphine, fentanyl or other long acting opioids?|
|Admit to ICU||Observe for 4-6 hours after last naloxone dose|
|Patient fully awake and alert ?|
|Perform intubation, begin a continuous naloxone infusion||Admit to ICU|
|Continue infusion till respiratory depression reversed, observe 4-6 hours after naloxone infusion is stopped||Discharge patient, when awake & alert with stable vital signs|
Intra-nasal administration: In recent years, there has been an emphasis on studying the efficacy of intra-nasal administration of naloxone, to treat opioid overdose in community. The studies have all converged to the fact that, the efficacy and safety are comparable to other routes of administration, that it is likely to reduce blood exposure in paramedics and can be successfully given even by bystanders.  
The U.S. Centers for Disease Control and Prevention (CDC) estimates that US programs for drug users and their caregivers prescribing take-home doses of naloxone and training on its utilization are estimated to have reversed 10,000 opioid overdose deaths. Healthcare institution-based naloxone prescription programs have also helped reduce rates of opioid overdose in the US state of North Carolina, and have been replicated in the US military. Nevertheless, scale-up of healthcare-based opioid overdose interventions is limited by providers’ insufficient knowledge and negative attitudes towards prescribing take-home naloxone to prevent opioid overdose. Programs training police and fire personnel in opioid overdose response using naloxone have also shown promise in the US.
Although opioid overdose accounts for the leading cause of accidental death, it can be prevented and often in primary care settings. Providers should routinely screen patients using tools such as the CADE-AID and the Drug Abuse Screening Test (DAST-10) to screen adults and the CRAFT to screen adolescents aged 14–18 years. Other “drug seeking” behaviors as well as physical indications of drug use should be used as clues to perform formal screenings. Individuals diagnosed with opioid dependence should be prescribed naloxone to prevent overdose and/or should be directed to one of the many intervention/treatment options available, such as needle exchange programs and treatment centers. Brief motivational interviewing can also be performed by the clinician during patient visits and has been shown to improve patient motivation to change their behavior. Despite these opportunities, the dissemination of prevention interventions in the US has been hampered by the lack of coordination and sluggish federal government response.
