Neuroadaptation, Tolerance, and Withdrawal
• Neuroadaptation is the brain’s response to over stimulation from drugs. Sedation and stimulation (intoxication) are the result of excessive drug-specific effects on brain functions.
• Tolerance is the process by which the reward and pleasure centers of the brain adapt to high concentrations of pleasure neurotransmitters. In direct response to overstimulation, the brain regions decrease in sensitivity and become unresponsive (deaf) to normal levels of stimulation.
In addition to pleasure circuits each drug type affects other brain functions.. Other brain pathways overstimulated by drugs also neuroadapt and become under active, directly leading to anxiety, depression, and loss of energy.
• Once neuroadaptation develops (tolerance), there will always be Withdrawal symptoms that are the mirror image of the drug effects. Cessation of drug use leads to ‘inversion of the high’; sobriety becomes pleasureless, anxious, sleepless, and lacking energy
• Under unstimulated conditions (without drugs) there is profound interference with the ability to experience normal pleasure. When sober, the user experiences Craving: anhedonia, anxiety, anger, frustration. The pleasure system remains impaired for months to years, interfering with sobriety, learning, and impulse inhibition.
• Compulsion: loss of controlThe user can’t not do it s/he is compelled to use.Compulsion is not rational and is not planned.
• Continued use despite adverse consequencesAn addict is a person who uses even though s/he knows it is causing problems.Addiction is staged based on adverse consequences.
• Craving: daily symptom of the diseaseThe user experiences intense psychological preoccupation with getting and using the drug. Craving is dysphoric, agitating and it feels very bad.
• Denial/hypofrontality: distortion of cognition caused by cravingUnder the pressure of intense craving, the user is temporarily blinded to the risks and consequences of using.
Definition of Addiction
Causes of Craving in Addicts
E W M S
• Environmental cues (Triggers)immediate, catastrophic, overwhelming craving stimulated by people, places, things associated with prior drug-use experiences
• Drug Withdrawal inadequately treated or untreated
• Mental illness symptoms inadequately treated or untreated
• Stress equals craving
Opiate Effects
• Analgesia• Euphoria• Anxiolytic- calming• Sleep Inducing• Sensation of warmth• Constipation• Dry mucous membranes• Pupils constrict (pinpoint pupils)
• Sedation/Sleepiness (nodding)• Depresses respiration
Physical Dependence
• ToleranceNeuroadaptation forces the user to increase the dose to maintain the effect of the drug.
Using an inadequate dose causes withdrawal: symptoms occur when the amount used is less than the tolerance level.
• Physical DependenceWhen the user stops the drug, physical illness results.
• Abstinence SyndromeName of the illness caused by withdrawal symptoms.
Core Principles in the Use of Opiates for Treatment of Chronic Pain:
1. Detox from all sedative-hypnotic drugs, with meticulous attention to avoid all withdrawal symptoms
2. Substitute all opiates with sustained-release or long-acting opiates: MS Contin, methadone, suboxone
3. Titrate dose to optimum, the dose that relieves pain and relieves pain without sedation
4. Avoid use of "breakthrough" medication
Opiate Withdrawal
• Pain
• Dysphoria
• Anxiety
• Insomnia
• Diarrhea
• Rhinorrhea• Chills
• Pupils dilate
• Increases heart rate & blood pressure

Overview of Buprenorphine (Suboxone and Subutex)
• Highly safe medication (acute & chronic dosing).
• Primary side effects: like other mu agonist opioids (e.g.,nausea, constipation) but may be less severe.
• No evidence of significant disruption in cognitive or psychomotor performance with buprenorphine maintenance.
• No evidence of organ damage with chronic dosing.

One Year Outcome of Opiate Treatment
• Overall, the dismal outcome for our controls reiterates the grave nature of heroin dependence, and shows the considerable health and social difficulties faced by our patients.
• Furthermore, the severity of problems in our patient sample is tragically emphasised by the 20% mortality in the controls over the course of a 1-year study.
Opiate Progression Pills to the Needle
Historically, untreated dependence on prescription opiates led to a trajectory from
• Pills ingested orally
• Pills crushed and snorted or smoked
• Pills injected
• Heroin snorted or smoked
• Heroin used intravenously
• This progression develops over from 12 to 24 months

Special Problems in Former Opiate Addicts
Persons previously addicted to opiates
• Have low pain tolerance because endogenous analgesic mechanisms are impaired.
• Will “uncover” their previous level of opiate tolerance over 4 - 6 weeks and require upward dosage titration over an extended time (despite years of abstinence).
• Require doses 2 to 4 times higher for analgesia than non-tolerant persons (due to high opiate tolerance).
• Need slower, symptom-driven tapers to discontinue opiates.

Withdrawal Management
Opiate Substitution
• Query: time since last opiate use • Query: all opiates used in past 7 days. • Calculate client's usual 24 hour opiate dose.
• Query: prior withdrawal experience(s).• Query: other drugs used:
alcoholillicit drugsprescription medicationsover-the-counter preparations
• Determine if client requires other detoxification
Withdrawal Management
Substitution MethodologyOpiates
• Calculate Suboxone dose using opiate dose equivalents.
• Give first Suboxone dose (2 - 8 mg) when objective and clear signs of withdrawal are evident.
• Record Pulse, BP, and withdrawal SX on Symptom Assessment sheet.
• Recheck Pulse & Blood Pressure after 90 minutes.
• Give 1/4 of estimated daily Suboxone dose when withdrawal symptoms reappear.
• Give the remainder of Suboxone in divided doses every 6 - 8 hours.
Withdrawal Management
Completion of Substitution Phase
Substitution is complete when the patient feels “normal,” and craving goes away.
Persistence of insomnia, anxiety, pain, or depression indicate need for separate treatment of these symptoms (dual diagnosis).
The patient is now ready for taper or for maintenance.
Withdrawal Management
Taper Phase
There are two variables in tapering: Dose: how much to taper
Time: how often to taper
Dose reductions are adjusted so that the patient does not re-enter withdrawal. If withdrawal symptoms develop during taper, return to previous effective dose, reduce amount of taper (dose) or lengthen the (time) interval. Do not continue until symptoms subside.
• Monitor Pulse and Blood Pressure daily• Complete Symptom Assessment sheet daily.• Adjust amount decreased and time between decreases to maintain
symptom scores at 0-1
