In this study, too, patients presenting mild pain were very few compared to the patients presenting moderate to severe pain, making gabapentinoid-based combination therapy the most preferred treatment in the patients. Pregabalin with nortriptyline was the second preferred combination, followed by pregabalin with nortriptyline in patients with moderate to severe neuropathic pain. Although pregabalin with gabapentinoid benefit and risk stratification: mechanisms over myth pmc duloxetine was prescribed in more patients, pregabalin with nortriptyline demonstrated a slightly higher improvement rate of 85.32% vs. 83.78% in the pregabalin-duloxetine group.
This emphasizes the critical nature of vigilant observation and the need for flexibility to modify treatment strategies. A diagnosis of pregabalin dependence was made, keeping in mind her constant desire to take the medicine, withdrawal symptoms in the form of dizziness, headache, irritability, restlessness, disturbed sleep, lack of interest in day-to-day activities, and continued use despite knowing the harmful effects of long-term use. The weight of evidence however favors a more prominent “desensitization” action mediated via inhibition of α2δ-subunits of presynaptic voltage-dependent calcium channels (e.g., leading to decreased activity-dependent excitatory neurotransmission), which in essence inhibits the development of addiction’s behavioral sensitization 10, 11. Along those lines, even pregabalin (well-accepted as possessing a greater potential for abuse and dependence liability) has been recently shown in a rodent model to confer significant reduction in brain dopamine, glutamate, and norepinephrine 12. Ample preclinical evidence exists that NMDAR blockade seems to increase opioid pursuit/use under certain circumstances that seem to indicate that this antagonism may elicit a compensatory increase in opioid use to offset reduced reward and reinforcement 54.
Conclusion-Benefit:Risk Stratification, or Patient Selection
- One found attenuation of opioid withdrawal symptoms as the most common reason, endorsed by 67% of respondents, but found abuse indicators such as synergism with other substances (52%), recreation (47%) and curiosity (41%) reported in similar magnitude 9.
- A 55-year-old female patient with a history of an old fracture of the L2 vertebra presented to the Department of Physical Medicine and Rehabilitation of a tertiary healthcare facility with complaints of low back pain for the last 20 years, with radiation of pain to her right lower limb.
- The emergence of a substantial sample seeking detoxification and other addiction medicine services should be a conditio sine qua non for a widely used/misused, allegedly strongly addictive, and thereby potentially socially harming substance; and yet we have not yet witnessed this phenomenon despite years of opportunity for its development.
- The treating neurologists considered the severity of the patient’s pain while choosing the treatment.
It should be noted that congruent skew has been shown for NSAIDs and antibiotics, and obviously may represent heterogeneity of indications among other covariates. According to the physicians’ subjective assessment, 82.5% of them had observed a recent increase in pregabalin use by their patients and 89.1% of them reported that their patients requested pregabalin without a clear medical indication. Patients misusing pregabalin in combination with other illicit substances were observed by 93.3% of the physicians surveyed. According to 73.5% of the physicians surveyed, they had already encountered patients on pregabalin doses of more than 600 mg/day (the maximum recommended daily dose); the highest dose reported was 4,200 mg/day.
Safety, tolerability, and efficacy of a selective gabapentinoid mirogabalin in neuropathic pain—a topical review
These (and other anticonvulsants) carry substantial advantage over the tradition-rich benzodiazepines in terms of increased safety/no interactions with alcohol, but also in terms of no evident cross-substance dependence and transfer of addiction 35, 57. One study applied the 49-question version of the Addiction Research Center Inventory (ARCI) in the assessment of abuse potential of gabapentin in alcoholics. The ARCI is the most well-studied and validated instrument used to compare abuse liability of a substance to five standard drug groups (Morphine-Benzadrine, Pentobarbitol-Chlorpromazine-Alcohol, LSD, Benzadrine, and Amphetamine).

- This possibly results in the efficacy of gabapentinoids in the management of neuropathic pain.
- Gabapentinoids were initially created as GABA mimetics; however, they bind to the alpha-2-delta subunit of voltage-gated calcium channels and not the GABA receptors directly (3).
- There is sufficient evidence to warrant caution when prescribing gabapentinoids, and this caution should be heightened among patients with an opioid use disorder or those who concurrently use high-dose opioids, especially with other central nervous system depressants.
- This is an indication that prescribers are reluctant to use pregabalin as a result of negative experiences.
In addition, we examined the prevalence of gabapentin use stratified by age groups (65 to 74 years; 75 to 84 years; and 85+ years) and sex across different categories of cognitive status. To our knowledge, the utilization of gabapentin in older adults with different cognitive statuses has not been studied yet. Therefore, this study aimed to examine trends of gabapentin use among older adults with different levels of cognitive status and to assess concurrent use of gabapentin with CNS-depressant medications. The global burden of ALD is growing and compounded by frequent late-stage diagnosis and undertreatment.

Sleep Disorders and Headache: A Review of Correlation and Mutual Influence
A 55-year-old female patient with a history of an old fracture of the L2 vertebra presented to the Department of Physical Medicine and Rehabilitation of a tertiary healthcare facility with complaints of low back pain for the last 20 years, with radiation of pain to her right lower limb. For the past 10 years, the patient was on a combination of Aceclofenac (200 mg) and pregabalin (75 mg) at night to alleviate her pain. Although initially prescribed for two weeks, she continued using them without further consultation, leading to her dependence on pregabalin. Some countries have enacted regulations to control the increasing trend in the off–label use of gabapentinoids.
After a week of follow-up, the patient and her informant reported symptoms of significant irritability and facial deviation/movements. She was also referred to the Department of Psychiatry for her irritability, sleep disturbance, facial movements, and unresolved pain complaints. We introduced a new treatment regimen that included Aceclofenac (100 mg) and paracetamol (325 mg) on an as-needed basis, and pregabalin (75 mg) twice a day, which replaced the previous cumulative dose of 150 mg taken at night.
The investigators found no difference between gabapentin and placebo among all the various axes of subjective effect 58. Given that gabapentinoids are meanwhile widely distributed and easily obtainable via the internet or black markets, one would expect many more of these cases if gabapentinoids possessed meaningful addictive power. The limited reward-based (as opposed to co-administered substance withdrawal prophylaxis as described in following text) attractiveness of gabapentinoids among certain populations seems to rest upon their short-term euphoric and sedating effects (“liking”) rather than upon any sustained psychological dependence effects (“wanting”) 57, 58.
This possibly results in the efficacy of gabapentinoids in the management of neuropathic pain. Gabapentinoids also facilitate slow-wave sleep, a relatively rare phenomenon among central nervous system-acting agents, which is also thought to explain some of the therapeutic benefits of the class in conditions such as fibromyalgia. A systematic review by Evoy et al. suggests that there is a growing trend of gabapentinoid misuse and abuse, resulting in harm to patients 9. Healthcare providers should thus exercise caution, particularly when dealing with high-risk patients, and remain vigilant for any signs of misuse or abuse.
