Opioid withdrawal syndrome (withdrawal syndrome)
Withdrawal syndrome (WS) is a reliable sign of established ophiomania. Acute manifestations begin 8–16 hours after the last dose, with peak severity occurring on days 3-4. In favorable cases, the acute phase subsides by days 7-10.
Symptom progression dynamics:
- Initial stage: onset of pronounced anxiety and restlessness.
- Autonomic disorders: incessant sneezing, lacrimation, rhinorrhea. Hyperhidrosis, chills, elevated blood pressure, and tachycardia are typical. Acrocyanosis and persistent mydriasis (pupillary dilation) are observed.
- Sleep disturbances: onset of stubborn insomnia.
- Pain syndrome ("cold turkey"): intense pain in the lower back, spine, and legs.
- Gastrointestinal disorders: on days 1-2, abdominal cramps, repeated vomiting, and diarrhea with tenesmus occur.
Against the background of WS, there is a catastrophic loss of behavioral control. To obtain the drug and relieve withdrawal, patients may resort to any actions, including criminal ones.
Development of ophiomania and consequences
Opioid dependence develops in an extremely short time. Psychological craving (primary urge) appears after the very first uses. With regular intravenous administration of substances such as heroin, physical dependence is established in just one to two weeks. Subsequently, the drug is used not for euphoria, but solely to prevent excruciating withdrawal syndrome.
Somatic and infectious complications:
- Toxic damage to internal organs: hepatitis, pancreatitis, nephritis, cardiomyopathies.
- Neurological pathologies: polyneuropathy, lowered seizure threshold.
- Sharp weight loss and vitamin deficiency against the background of loss of appetite.
- High risk of HIV, viral hepatitis, and syphilis infection due to sharing needles.
The disease has a chronic, progressive course. Complete recovery is unattainable, as craving persists for life, though long periods of remission are possible. The average life expectancy from the onset of the disease is about 7 years.
Principles of opioid dependence treatment
The baseline treatment principle is simultaneous and abrupt discontinuation of the drug. Since opioid WS does not pose a direct threat to life, gradual dose reduction is impractical.
Main areas of therapy:
- Pain management: non-narcotic analgesics (metamizole sodium, diclofenac) are used, often combined with neuroleptics and anticholinergics. Tramadol can be used short-term (for 3-4 days), but it can prolong the withdrawal process.
- Curbing cravings: clonidine is prescribed (in high doses, under strict hemodynamic monitoring) and sedative neuroleptics (haloperidol, thioridazine).
- Symptom support: short courses of tranquilizers for sleep (diazepam), anticonvulsants (carbamazepine), non-stimulating nootropics for asthenia, and hepatoprotectors.
To maintain remission, the opiate receptor antagonist naltrexone is used. It is prescribed no earlier than 10 days after the last opioid intake, and a control naloxone test must be performed. In case of a positive reaction, starting naltrexone therapy is strictly prohibited.
Dependence on cocaine and other psychostimulants
The clinical picture of stimulant dependence largely depends not on the chemical formula of the substance, but on the route of administration (smoking, injection, intranasal) and the presence of adulterants.
- Cocaine: historically used as a local anesthetic (before the advent of procaine and lidocaine) and even included in tonic beverages until 1906. Currently most widespread in North America and several European countries.
- Amphetamines: initially synthesized as a cold remedy, later used in medicine to treat depression, obesity, and narcolepsy. They cause marked stimulation, suppress appetite, and allow staying awake at night. Due to high addiction potential, amphetamines have been under strict control since the 1970s.
- Caffeine: dependence is rare and requires systematic consumption of extremely high doses (from 8 cups of coffee per day). Risk groups include night-shift workers and individuals in correctional facilities consuming concentrated tea extract ("chifir").
Briefly: answers to topical questions
Which substances are classified as classical hallucinogens?
- LSD (Lysergic acid diethylamide) is a synthetic hallucinogen.
- Mescaline (Mescaline) is a plant-derived hallucinogen from the Lophophora cactus.
- Psilocybin (Psilocybin) is a plant-derived hallucinogen found in psychedelic mushrooms.
What is the mechanism of action of hallucinogens on neurotransmitter systems?
- Serotonin system — serotonin derivatives, such as LSD and psilocybin, cause short-term psychosis.
- Dopamine system — dopamine analogues, such as mescaline, can induce psychosis.
Does physical dependence and withdrawal syndrome develop with hallucinogen use?
With hallucinogen use, sources describe psychological dependence: a sharp drop in mood background, emotional discomfort, a feeling of fatigue and depression in the absence of pronounced somatic disorders. Hallucinogens, particularly LSD, are cited as typical agents of psychological dependence.
Class and exam questions
What is the purpose of the naloxone challenge test?
This is the administration of an opiate receptor antagonist to provoke withdrawal symptoms (mydriasis, lacrimation, dyspnea). A positive test proves the patient has physical dependence on opioids.
Can opioids be tapered off during treatment?
The provided material indicates that the main principle is simultaneous (abrupt) drug discontinuation, as withdrawal syndrome itself is not life-threatening.
Do heroin users develop dementia?
When using purified drugs, intellectual-mnestic deficits usually do not occur. However, they are clearly manifested with the use of homemade, chemically processed opiate preparations.
