“drug withdrawal syndrome”
“substance withdrawal syndrome”
.
Drug withdrawal is the group of symptoms that occur upon the abrupt discontinuation or decrease in the intake of pharmaceutical or recreational drugs.
In order for the symptoms of withdrawal to occur, one must have first developed a form of drug dependence.
This may occur as physical dependence, psychological dependence, or both. Drug dependence develops from consuming one or more substances over a period of time.
Dependence arises in a dose-dependent manner and produces withdrawal symptoms that vary with the type of drug that is consumed. For example, prolonged use of an antidepressant medication is likely to cause a rather different reaction when discontinued compared to discontinuation of an opioid, such as heroin. Withdrawal symptoms from opiates include anxiety, sweating, vomiting, and diarrhea. Alcohol withdrawal symptoms include irritability, fatigue, shaking, sweating, and nausea. Withdrawal from nicotine can cause irritability, fatigue, insomnia, headache, and difficulty concentrating. Many prescription and legal nonprescription substances can also cause withdrawal symptoms when individuals stop consuming them, even if they were taken as directed by a physician.
The route of administration, whether intravenous, intramuscular, oral, or otherwise can also play a role in determining the severity of withdrawal symptoms.[citation needed] There are different stages of withdrawal as well; generally, a person will start to feel bad (crash or come down), progress to feeling worse, hit a plateau, and then the symptoms begin to dissipate. However, withdrawal from certain drugs (barbiturates, benzodiazepines, alcohol, glucocorticoids) can be fatal.[2][3] While it is seldom fatal to the user, withdrawal from opiates (and some other drugs) can cause miscarriage, due to fetal withdrawal. The term “cold turkey” is used to describe the sudden cessation of use of a substance and the ensuing physiologic manifestations.
The symptoms from withdrawal may be even more dramatic when the drug has masked prolonged malnutrition, disease, chronic pain, infections (common in intravenous drug use), or sleep deprivation, conditions that drug abusers often develop as a secondary consequence of the drug. When the drug is removed, these conditions may resurface and be confused with withdrawal symptoms. Genes that encode for the alpha5 nicotinic acetylcholine receptor affect nicotine and alcohol withdrawal symptoms.
Effect on homeostasis
[edit]
Homeostasis is the body’s ability to maintain a certain chemical equilibrium in the brain and throughout the body. For example, the function of shivering in response to cold is to produce heat maintaining internal temperature at around 37 °C (98.6 °F). Homeostasis is impacted in many ways by drug usage and withdrawal. The internal systems perpetuate homeostasis by using different counter-regulatory methods in order to create a new state of balance based on the presence of the drug in the system.[4] These methods include adapting the body’s levels of neurotransmitters, hormones, and other substances present to adjust for the addition of the drug to the body.[5]
Addiction and dependence glossary[6][7][8]
addiction – a biopsychosocial disorder characterized by persistent use of drugs (including alcohol) despite substantial harm and adverse consequences
addictive drug – psychoactive substances that with repeated use are associated with significantly higher rates of substance use disorders, due in large part to the drug’s effect on brain reward systems
dependence – an adaptive state associated with a withdrawal syndrome upon cessation of repeated exposure to a stimulus (e.g., drug intake)
drug sensitization or reverse tolerance – the escalating effect of a drug resulting from repeated administration at a given dose
drug withdrawal – symptoms that occur upon cessation of repeated drug use
physical dependence – dependence that involves persistent physical–somatic withdrawal symptoms (e.g., fatigue and delirium tremens)
psychological dependence – dependence socially seen as being extremely mild compared to physical dependence (e.g., with enough willpower it could be overcome)
reinforcing stimuli – stimuli that increase the probability of repeating behaviors paired with them
rewarding stimuli – stimuli that the brain interprets as intrinsically positive and desirable or as something to approach
sensitization – an amplified response to a stimulus resulting from repeated exposure to it
substance use disorder – a condition in which the use of substances leads to clinically and functionally significant impairment or distress
tolerance – the diminishing effect of a drug resulting from repeated administration at a given dose

Examples (and ICD-10 code) of withdrawal syndrome include:
F10.3 alcohol withdrawal syndrome (which can lead to delirium tremens)
F11.3 Opioid withdrawal, including methadone withdrawal[9]
F12.3 cannabis withdrawal
F13.3 benzodiazepine withdrawal
F14.3 cocaine withdrawal
F15.3 caffeine withdrawal
F17.3 nicotine withdrawal
Prescription medicine
[edit]
As noted above, many drugs should not be stopped abruptly[10] without the advice and supervision of a physician, especially if the medication induces dependence or if the condition they are being used to treat is potentially dangerous and likely to return once medication is stopped, such as diabetes, asthma, heart conditions and many psychological or neurological conditions, like epilepsy, depression, hypertension, schizophrenia and psychosis. The stopping of antipsychotics in schizophrenia and psychoses needs monitoring.[11] The stopping of antidepressants for example, can lead to antidepressant discontinuation syndrome. With careful physician attention, however, medication prioritization and discontinuation can decrease costs, simplify prescription regimens, decrease risks of adverse drug events and poly-pharmacy, focus therapies where they are most effective, and prevent cost-related under-use of medications.[12]
Medication Appropriateness Tool for Comorbid Health Conditions in Dementia13 warns that people with dementia are more likely to experience adverse effects, and to monitor carefully for withdrawal symptoms when ceasing medications for these people as they are both more likely to experience symptoms and less likely to be able to reliably report symptoms.[14]
Anti-hypertensive drugs
[edit]
The latest evidence does not have evidence of an effect due to discontinuing vs continuing medications used for treating elevated blood pressure or prevention of heart disease in older adults on all-case mortality and incidence of heart attack.[15] The findings are based on low quality evidence suggesting it may be safe to stop anti-hypertensive medications. However, older adults should not stop any of their medications without talking to a healthcare professional.[15]

Despite the importance of numerous psychosocial factors, at its core, drug addiction involves a biological process: the ability of repeated exposure to a drug of abuse to induce changes in a vulnerable brain that drive the compulsive seeking and taking of drugs, and loss of control over drug use, that define a state of addiction. … A large body of literature has demonstrated that such ΔFosB induction in D1-type [nucleus accumbens] neurons increases an animal’s sensitivity to drug as well as natural rewards and promotes drug self-administration, presumably through a process of positive reinforcement … Another ΔFosB target is cFos: as ΔFosB accumulates with repeated drug exposure it represses c-Fos and contributes to the molecular switch whereby ΔFosB is selectively induced in the chronic drug-treated state.41. … Moreover, there is increasing evidence that, despite a range of genetic risks for addiction across the population, exposure to sufficiently high doses of a drug for long periods of time can transform someone who has relatively lower genetic loading into an addict.

Substance-use disorder: A diagnostic term in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) referring to recurrent use of alcohol or other drugs that causes clinically and functionally significant impairment, such as health problems, disability, and failure to meet major responsibilities at work, school, or home. Depending on the level of severity, this disorder is classified as mild, moderate, or severe.
Addiction: A term used to indicate the most severe, chronic stage of substance-use disorder, in which there is a substantial loss of self-control, as indicated by compulsive drug taking despite the desire to stop taking the drug. In the DSM-5, the term addiction is synonymous with the classification of severe substance-use disorder.
