A study by Jones and Sorkin (1998) indicates that pregabalin inhibits voltage-dependent calcium channels (VDCCs) to nearly 6-fold the extent of gabapentin (assuming equal dosing). Furthermore, most patients reported that there were no differences between gabapentin and pregabalin in onset and duration of action – but some claimed that onset of action became quicker and/or duration of action increased. Moreover, it’s reasonable to suspect that pregabalin is more effective than gabapentin if high doses (particularly supratherapeutic dosages) are ever required due to its high bioavailability (90%) irrespective of dosing – compared to the diminishing bioavailability of gabapentin at high doses (27%). If you’re a person who found one gabapentinoid (pregabalin or gabapentin) to be superior over the other in efficacy and/or tolerability, have you considered that these differences might be explained by disparities in treatment-related variables like: potency of dosing (e.g. Dosing options: There are a greater number of dosing options for pregabalin (Lyrica) than gabapentin (Neurontin). On the other hand, Pregabalin commands a higher price on the market. For example, persons who use gabapentinoids “as needed” for intermittent and/or short-term management of medical symptoms might only require symptom management for 4 to 6 hours – making gabapentin a potentially-superior choice over pregabalin. opioids; alcohol; amphetamines; benzodiazepines). 32. At this time, there’s no convincing evidence to substantiate the recommendation that pregabalin is superior to gabapentin in the treatment of postherpetic neuralgia. The greater number of dosing increments for pregabalin may decrease the likelihood that users need to split capsules while titrating in effort to find an optimal (tolerable and effective) dose. (2010) suggested that pregabalin might be more effective than gabapentin in the treatment of partial onset seizures, however, sensitivity analyses revealed no statistically-significant differences in the efficacies of pregabalin and gabapentin. Over the course of a 1-year span, prescription expenses for daily Lyrica users will exceed $5200 – whereas prescription expenses for daily gabapentin (generic Neurontin) users will range from $120 to $468. Schifano also noted that misusers of pregabalin or gabapentin tend to have histories of recreational poly-drug misuse and generally administer 3-to-20-fold the clinically-recommended dosages of these agents. Pregabalin (brand name Lyrica) and gabapentin (brand name Neurontin) are both medications used to treat seizures, pain related to shingles, and certain other types of nerve pain. Gabapentin is the generic of a different medication, Neurontin. In response to the aforementioned secondary neurochemical actions facilitated by pregabalin and gabapentin: (1) inhibitory (GABAergic) neurotransmission increases; and (2) excitatory (glutamatergic) neurotransmission decreases. 1. Moreover, in the standalone trial involving a transition from gabapentin to pregabalin (of an equally-potent dose), no differences were reported in respective efficacies of these medications for postherpetic neuralgia. It was concluded that pregabalin may provide additional pain relief relative to gabapentin in the treatment of neuropathic pain. Imbalanced physiologic activation lingering from pregabalin or gabapentin cessation is what causes noticeable physical and/or psychological reactions characterized as “withdrawal symptoms.” Although physiologic activation will eventually adjust or revert back to pre-gabapentinoid homeostasis, this homeostatic reversion requires time (weeks, months, etc.). 5. Nonetheless, it’s possible that some individuals will respond significantly better to pregabalin (relative to gabapentin) – and others will respond significantly better to gabapentin (relative to pregabalin). Wang et al. (The oral bioavailability of pregabalin (Lyrica) is not affected by dosage or whether administered with a meal). Results indicated that visual analogue scale (VAS) pain scores did not significantly change after the transition from gabapentin to pregabalin. Bockbrader HN, Wesche D, Miller R, Chapel S, Janiczek N, Burger P. A comparison of the pharmacokinetics and pharmacodynamics of pregabalin and gabapentin. The cost of brand name Lyrica oral solution doesn’t differ much from that of brand name Neurontin oral solution – but the former (Lyrica) is slightly cheaper than the latter (Neurontin). On the other hand, Pregabalin commands a higher price on the market. It may also be likely that the shorter duration of action associated with gabapentin among infrequent or “as needed” users decreases likelihood of tolerance onset – relative to pregabalin. Lyrica is the brand name for the drug pregabalin, and gabapentin is the name of the medication that is used in drugs such as Neurontin, Gralise, and Horizant. Gralise [Package insert]. 2. It is extremely common for former pregabalin (Lyrica) and gabapentin (Neurontin) to report withdrawal symptoms that persist for weeks after the date of treatment cessation. Pharmacokinetic research by Bockbrader et al. According to side effect data compiled by the FDA, pregabalin is more likely (than gabapentin) to cause: blurred vision, weight gain, difficulty concentrating, dry mouth, and increased appetite – and gabapentin is more likely (than pregabalin) to cause: ataxia, fatigue, nystagmus, fever, nausea, vomiting, and hostility. That said, there are numerous limitations associated with this study, including: (1) more potent pregabalin dosing (~457 mg/day) relative to gabapentin (~2400 mg/day); (2) extraction of efficacy data from studies with different parameters (dosing regiments, durations, participant numbers, etc. 2010: Substitution of gabapentin therapy with pregabalin therapy in neuropathic pain due to peripheral neuropathy. Bar Ad V. Gabapentin for the treatment of cancer-related pain syndromes. Faster onset of action (? To date, no well-designed studies have directly compared pregabalin and gabapentin in the treatment of fibromyalgia. Gabapentin and pregabalin are used to treat both neuropathic pain and epilepsy. (2011) involving 90 women with abdominal hysterectomy pain reported that pregabalin is associated with fewer dose-related adverse reactions than gabapentin. Lyrica vs. Gabapentin: Addiction and Dependence. therapeutic responses) than gabapentin users. Amitriptyline (Elavil) Withdrawal Symptoms + How Long Do They Last? Various limitations associated with these studies included: (1) unequal potency (of dose) comparisons; (2) inflexible dosing; (3) indirect comparisons; (4) data extraction (from studies with parameter disparities); (5) inclusion of questionnaire data; (6) research and authorship by Pfizer Inc. employees; (7) potential reporting bias, sponsorship bias; and/or publication bias. 2012: Evaluation of efficacy and safety of gabapentin, duloxetine, and pregabalin in patients with painful diabetic peripheral neuropathy. To determine the respective adjunct efficacies of pregabalin and gabapentin in treating partial onset seizures, researchers tracked the percentage (%) change in 28-day seizure rate from baseline to treatment phase. 4. Though the primary neurochemical action facilitated by pregabalin and gabapentin is identical, the magnitude of this action differs between the medications. In standard format, pregabalin (Lyrica) exhibits an average duration of action from 8 to 14 hours – whereas gabapentin (Neurontin) exhibits an average duration of action from 5 to 8 hours. Lower cost: Another reason patients and/or medical professionals prefer using gabapentin (Neurontin) over pregabalin (Lyrica) is related to its significantly lower cost. The oral bioavailability of pregabalin (Lyrica) at ~90% is significantly greater than that of gabapentin (Neurontin) ranging from ~27% to ~60% (depending on dosage and whether administered with a high-fat meal). Average final doses for gabapentin and pregabalin were 1067.1 ± … In a meta-analysis by Quilici et al. Due to its lower price, Gabapentin is the more attractive option between the two drugs. Neurontin: The cost for 90 100mg strength capsules is approximately $18. Overall, assuming that pregabalin and gabapentin are administered in accordance with proper medical instruction, risk of abuse/addiction is extremely low. In total, pregabalin is FDA-approved to treat 5 medical conditions – whereas gabapentin is FDA-approved to treat 2 medical conditions. Primarily, these two medications are beneficial in treating epileptic seizures and other medical conditions. I was taking Lyrica and was still in pain, my doctor switched me to Gabapentin and at first I thought it was better. In studies that’ve directly or indirectly compared the efficacy of pregabalin to gabapentin for the treatment of neuropathic pain, none have proven that one medication (pregabalin or gabapentin) exhibits superior efficacy relative to the other. Lexapro (Escitalopram) vs Zoloft (Sertraline): Extensive Comparison, Pregabalin (Lyrica) vs. Gabapentin (Neurontin). Gabapentin and Pregabalin are drugs that are often mistaken as synonymous with each other. Standard pregabalin is sold in 8 total dosing increments (25 mg, 50 mg, 75 mg, 100 mg, 150 mg, 200 mg, 225 mg, 300 mg) – whereas standard gabapentin is sold in 5 total dosing increments (100 mg, 300 mg, 400 mg, 600 mg, 800 mg). (2007) that’s evaluated the efficacy of gabapentin in fibromyalgia. It's maximum absorption rate is nearly three times gabapentin. Hypothesized physiologic adaptations that might occur and/or accumulate with regular pregabalin or gabapentin administration, include: (1) downregulation of α2δ subunits of voltage-dependent calcium channels; (2) altered mRNA and protein levels of α2δ subunits; (3) decreased endogenous GABA production via enzymes; (4) increased endogenous glutamate production via enzymes; and (5) upregulation of NMDA receptors. 2010;5(3):174-178. neuropathic pain) require long-term treatment with gabapentinoids, patients might save themselves money and time by opting to use gabapentin instead of pregabalin. Pregabalin, like gabapentin, is an amino acid derivative of gamma-amino butyric acid (GABA analogue). Another study documented a trend for better efficacy with pregabalin in the treatment of partial onset seizures – relative to gabapentin. For this study, 32 patients diagnosed with postherpetic neuralgia (who had been receiving gabapentin treatment) were transitioned from gabapentin to pregabalin at one-sixth the dosage (in effort to maintain approximately equal potencies of action). In many of these variables, there aren’t clinically-significant differences between pregabalin and gabapentin. Certain individuals might also prefer using gabapentin tablets instead of capsules on the basis that tablets are easier to split for dosage adjustments (relative to capsules which require pouring out and/or measuring powder). Although sensitivity analyses substantiated the findings of the base-case analysis, the sensitivity analyses did not find statistical significance between pregabalin and gabapentin. Though pregabalin and gabapentin negligibly differ in elimination half-life, the agents significantly differ in oral bioavailability (percentage of the medication that exerts a physiologic effect). Assuming a person has poor health insurance, using gabapentin could result in thousands-of-dollars in annual savings (relative to using Lyrica). Gabapentin prescriptions can be filled electronically and refilled without frequent follow-up doctor appointments. Celexa (Citalopram) vs. Lexapro (Escitalopram): Which Is Better? The primary endpoint was DPNP-related pain score on an 11-point visual analogue scale (VAS), and secondary endpoints included: sleep interference scores, patient global impression of change, and clinical global impression of change. In the treatment of neuropathic pain pregabalin has been shown in studies to provide equivalent efficacy to gabapentin… The availability of gabapentin in multiple long-acting preparations might be perceived as favorable relative to the standalone long-acting preparation of pregabalin – based on the fact that patients have an alternative if the first long-acting preparation tested exhibits suboptimal efficacy and/or tolerability. Blurred vision. If you have experience with the gabapentinoid medications – pregabalin (Lyrica) and gabapentin (Neurontin), leave a comment regarding whether you: (A) prefer one medication over the other OR (B) have no substantial preference for using one medication over the other. 1. Both drugs have been found to be useful for treating generalized anxiety disorder (GAD). Results of the trial indicated that gabapentin recipients exhibited significantly: (1) greater reductions in fibromyalgia-related pain and (2) higher response rates after 12 weeks (from baseline) – relative to placebo recipients. Corresponding Author: David J. Greenblatt, Tufts University School of … (2010) suggests that both pregabalin and gabapentin exhibit elimination half-lives of approximately 6 hours. Although pregabalin (Lyrica) and gabapentin (Neurontin) are both available in the formats of capsule and oral solution – there are a greater number of dosing increments for pregabalin capsules (8 total) than dosing increments for gabapentin capsules (3 total). A reduction in activation of voltage-dependent calcium channels (VDCCs) [facilitated by pregabalin and gabapentin] simultaneously (1) bolsters inhibitory neurotransmission and (2) reduce excitatory neurotransmission to induce a combination of: analgesic, anticonvulsant, anxiolytic, and sedative effects. Essentially, because the body cannot use a large percentage of high-dose gabapentin, the circulating excess (unused portion) could theoretically increase risk of adverse reactions and/or the severities of preexisting side effects. If comparing the long-acting formulations of pregabalin and gabapentin, one might perceive pregabalin controlled-release (CR) as being advantageous over gabapentin extended-release – as a result of its additional dosing increment (3 dosing increments for pregabalin CR vs. 2 dosing increments for gabapentin ER). Results of this study reported no statistically-significant differences between groups in pain reduction to suggest that one medication was more efficacious than another. However, a few months ago I started to experience inter-dose withdrawal from the gabapentin and Lyrica, and it's getting worse. Patients had an inadequate pain response to a stable dose of gabapentin (≥ 900 mg/day) for ≥ 5 weeks prior to study enrolment. Other sources estimate that pregabalin is 2-to-4-fold and 3-to-10-fold more potent than gabapentin as an analgesic and anticonvulsant, respectively. Gabapentin and pregabalin were significantly effective in reducing pain, however, gabapentin had fewer and less severe adverse events vs pregabalin. Offering amitriptyline, duloxetine, gabapentin, or pregabalin. However, because gabapentin users have access to tablets as an alternative to capsules and oral solution (whereas pregabalin users do not), it’s reasonable to state that gabapentin is favorable over pregabalin in its variety of formatting options. Specifically, the cost of 100 mg Lyrica oral solution ranges from $9.71 to $10.42 per dose, whereas the cost of [an approximately equivalent] Neurontin dose (600 mg) oral solution ranges from $10.90 to $11.40 per dose. There are a couple of important points to note. Researchers concluded that gabapentin, pregabalin, and duloxetine are of comparable efficacy in the treatment of diabetic peripheral neuropathic pain. Pregabalin has an increased binding affinity for the alpha-2-delta protein and is a more potent analgesic in neuropathic pain compared with gabapentin. 2. This study was long-term (6-week baseline phase & 21-week treatment phase); large-scale (484 patients), and utilized randomization. After 2 weeks of pregabalin treatment, researchers interviewed patients to determine: visual analogue scale (VAS) pain scores; shifts in onset of action and/or duration of action after transition to pregabalin; and incidence rates of common side effects. Specifically, pregabalin FDA-approved to treat: diabetic neuropathic pain; fibromyalgia; and spinal cord injury-related neuropathic pain – whereas gabapentin is not. Lyrica (Pregabalin) vs Gabapentin (Neurontin) Lyrica and Gabapentin are antiepileptic anticonvulsant drugs. Neurontin has been available as a low-cost generic (gabapentin) since 2004, whereas Lyrica is not yet available as a generic (pregabalin). In 2017, the United Kingdom opted to modify the legal classification of pregabalin and gabapentin from standard prescriptions to “Class C” controlled substances. Although withdrawal symptoms can occur in any former users of pregabalin or gabapentin, withdrawal symptoms tend to be most prevalent and of greatest severity among those who rapidly discontinue treatment (without tapering) after regular high-dose, long-term use. In the 2 simulation trials, pregabalin was reported to be more effective than gabapentin, however, these were “simulations” conducted with questionnaire data by Pfizer Inc. employees – not legitimate head-to-head comparisons. Pregabalin, like gabapentin, is an amino acid derivative of gamma-amino butyric acid (GABA analogue). Price of Pregabalin Vs. Gabapentin. Why? lol. However, that’s not to say that gabapentin abuse isn’t risky. If we assume that there are no differences between pregabalin and gabapentin in cost (prescriptions plus annual doctor appointments expenses required to attain prescriptions) and that there might be differences in pregabalin and/or gabapentin in efficacy and/or tolerability – then it makes sense to favor the use of pregabalin. One might perceive gabapentin (Neurontin) as modestly favorable over pregabalin (Lyrica) on the basis of its: (1) lower abuse potential; (2) shorter duration of action; (3) availability as a standard prescription; (4) greater number of formatting options; (5) lower cost. (Prognosticators expect Lyrica to become available as a generic in December 2018). Because no large-scale, randomized controlled trials have directly compared the acceptability/tolerability of pregabalin and gabapentin, it’s unclear as to whether one medication is significantly more tolerable than the other (especially when administered at equally-potent doses OR flexible-doses). That said, because there are serious limitations associated with this study, we cannot be confident that the results (suggesting that pregabalin is more effective than gabapentin in postherpetic neuralgia) are accurate or clinically-relevant. The oral bioavailability of pregabalin is ~90% – whereas the oral bioavailability of gabapentin ranges from ~27% to ~60%. The U.S. FDA-authorized medical uses of gabapentin (Neurontin) are limited to the 2 aforementioned conditions (postherpetic neuralgia and partial onset seizures). Sciatica the pain that travels from your low back down your leg is extremely common. Since Schedule V controlled-substances like pregabalin are more difficult to attain (and require more doctor visits for refills – which can be costly) versus “standard prescriptions” like gabapentin, many patients and medical doctors prefer using gabapentin over pregabalin whenever possible. Assuming patients with chronic medical conditions (e.g. He is CEO of Remitigate (remitigate.com), an opioid safety software development LLC. (2012) in which pregabalin, gabapentin, and duloxetine were directly compared in the treatment of peripheral neuropathy (among 152 patients) reported no significant differences in adverse reactions among users of these medications. Despite the suggestion by authors of this study that pregabalin may be more efficacious than gabapentin in the treatment of neuropathic pain, there are major limitations to consider. Any thoughts would be appreciated xx. Perhaps similar results would’ve occurred if users were transitioned from pregabalin to gabapentin – followed by increasing the gabapentin dosage (to a potency that exceeds a prior pregabalin dosage). The U.S. FDA-authorized medical uses of pregabalin (Lyrica) are not limited to the 2 aforementioned conditions (postherpetic neuralgia and partial onset seizures). Previous post: Celexa (Citalopram) vs. Lexapro (Escitalopram): Which Is Better? The withdrawal is even worse than the Valium. Alcohol use disorder. Gabapentin (Neurontin 1) and pregabalin (Lyrica 2) are first- and second-generation α2δ ligands, respectively, and are both approved for use as adjunctive therapy in pain control.Although they do not bind to gamma-aminobutyric acid (GABA) receptors they have been successfully used to treat neuropathic pain conditions. Support for the idea that gabapentin may carry lower risk of abuse/addiction than pregabalin includes: (1) the bioavailability of gabapentin is inversely proportionate to dose (pregabalin retains its high bioavailability irrespective of dose); (2) the ~6-fold lower magnitude of voltage-dependent calcium channel modulation facilitated by gabapentin relative to equally-dosed pregabalin; and (3) the lack of “euphoria” reported in gabapentin clinical trials (“euphoria” occurred in pregabalin clinical trials). using pregabalin with zero substance use 90 days prior – and gabapentin after recently discontinuing a psychiatric medication)? This reclassification was implemented in response to increases in rates of addiction, misuse, and deaths associated with the administration of pregabalin and gabapentin. Gabapentin VS Pregabalin. using another medication during pregabalin treatment and not gabapentin treatment); neurochemistry at baseline (e.g. Worthy of additional mention is the fact that pregabalin and gabapentin are each available in “longer-acting” formulations that facilitate a therapeutic effect of ~24 hours. Lyrica vs. Gabapentin for Anxiety. Since pregabalin is an "analog" of gabapentin it has virtually the same effect. Because studies suggest that pregabalin might be more effective than gabapentin (but none suggest the opposite), the potentially-superior efficacy of pregabalin makes it favorable over the gabapentin. One study developed a population pharmacokinetic model comparing pregabalin with gabapentin. If the differences in withdrawal symptoms between pregabalin and gabapentin are significant, this might be attributable to disparities in potency of dosing; treatment duration; discontinuation rates; and other variables. ; Partial seizures when taken together with other medicines in adults and children 3 … Pregabalin maintains a ~90% bioavailability at high doses – whereas the bioavailability of gabapentin continues dropping with dose escalation. Dizziness. Because postherpetic neuralgia (PHN) and partial onset seizures are the only conditions for which both pregabalin (Lyrica) and gabapentin (Neurontin) are approved to treat, medical doctors and consumers are probably most interested in determining how their respective efficacies compare in the management of these conditions. Though some hypothesize that pregabalin might be better tolerated than gabapentin (assuming potency of dosing is equal) due to its higher, dose-independent bioavailability – there’s no evidence from large-scale trials to support this hypothesis. Results of this simulation study suggested that pregabalin was more effective than gabapentin for the treatment of postherpetic neuralgia. From 1 April 2019, gabapentin and pregabalin have been reclassified as controlled drugs, leading to changes in how they are prescribed. Gabapentinoid drugs—specifically gabapentin (Neurontin) and pregabalin (Lyrica)—are increasingly being prescribed for pain because physicians and patients seek alternatives to … 3 Question 6. Athanasakis et al. However, considering the suboptimal methods and serious limitations of this study, we cannot be confident that the results (suggesting that pregabalin is more efficacious than gabapentin) are accurate and clinically-relevant. Researchers concluded that monotherapy with gabapentin, pregabalin, and duloxetine provide significant pain relief among patients with DPNP. Nystagmus. It was noted that the principal population at risk of gabapentinoid addiction consists of persons with a history of substance use disorders (especially opioid users and poly-drug users). Gabapentin vs. Pregabalin. The gabapentin and Lyrica helped me deal with the post acute withdrawal symptoms from the Valium. In the study, 47 patients served as a gabapentin control group – and 69 transitioned from gabapentin to pregabalin: 33 “gabapentin responders” and 36 “gabapentin nonresponders” (i.e. In comparison, Schedule V substances like pregabalin can only be refilled a maximum of 5 times within 6 months before additional doctor appointments are needed for further refills. Included below are summaries of studies in which the efficacies of pregabalin and gabapentin are discussed and/or compared for neuropathic pain and fibromyalgia. Neuropathic pain can come on with no warning or for no apparent reason. Limitations associated with this study include: (1) efficacies of pregabalin and gabapentin were determined using data extracted from studies with different parameters (dosing regiments, durations, participant numbers, etc. Nevertheless, the chemical structures of Lyrica and gabapentin are nearly identical to one another. effectiveness) of gabapentin and pregabalin in the treatment of postherpetic neuralgia. A 30-day supply of Lyrica capsules at a dosage of 300 mg per day ranges in price from $442 to $471, whereas a 30-day supply of Neurontin capsules/tablets at a dosage of 1800 mg per day ranges in price from $911 to $975 – making Lyrica the significantly cheaper option. Delahoy et al. Gabapentin also has several off-label uses to treat other conditions. At this time, there’s no convincing evidence to suggest that pregabalin and gabapentin differ in efficacy for the management of partial onset seizures. Neuropathic pain. Cannabidiol (CBD) Side Effects & Adverse Reactions, L-Tyrosine Side Effects & Adverse Reactions (List), Armour Thyroid Side Effects & Adverse Reactions (List), Remeron (Mirtazapine) Withdrawal Symptoms + How Long They Last. Part of the swap is to see if pregabalin will be more effective for my pain and it's also to see if I will lose some of the fluid that I have retained with gabapentin. Lyrica (pregabalin) is both chemically and structurally similar to gabapentin. The study is created by eHealthMe based on reports (from sources including the FDA) of 505,630 people who take Gabapentin and Pregabalin, and is updated regularly. 2010: Pregabalin versus gabapentin in partial epilepsy: a meta-analysis of dose-response relationships. This is not the case however. What’s more, pregabalin has been reported as 2-to-4-fold and 3-to-10-fold more potent than gabapentin as an analgesic and anticonvulsant, respectively. While there were trends for greater pain reduction, superior sleep improvement, and faster onset of therapeutic action with pregabalin (relative to gabapentin and duloxetine), there were no statistically-significant differences in outcomes between groups to suggest that one treatment was more or less effective than the others. The gabapentin and Lyrica helped me deal with the post acute withdrawal symptoms from the Valium. Vomiting. Higher bioavailability: The oral bioavailability of pregabalin (Lyrica) is high (~90%) regardless of dosing and/or whether administered with food – whereas the oral bioavailability of gabapentin (Neurontin) fluctuates between moderate (~60%) and low (~27%) depending on: dosing (bioavailability is inversely proportionate to dose) and food intake (high protein meals increase its bioavailability). Hypothetically assuming that poor methods and/or limitations didn’t affect the study outcome, it would seem as though pregabalin may be more useful than gabapentin in the treatment of postherpetic neuralgia. Alcohol withdrawal. However, at higher dosages, brand name Lyrica capsules become notably cheaper than brand name Neurontin capsules/tablets. Ataxia. (Standard-release), Capsule: 25 mg, 50 mg, 75 mg, 100 mg, 150 mg, 200 mg, 225 mg, 300 mg. Inhibits α2δ-subunits (α2δ-1 and α2δ-2) of voltage-dependent calcium channels (VDCC). Gabapentin for chronic neuropathic pain and fibromyalgia in adults. Dosage of pregabalin was increased [after transition from gabapentin] in 22 patients who requested increases due to insufficient symptom relief. Weight gain. Due to its lower price, Gabapentin is the more attractive option between the two drugs. Migraine (prophylaxis). Gabapentin (Neurontin 1) and pregabalin (Lyrica 2) are first- and second-generation α2δ ligands, respectively, and are both approved for use as adjunctive therapy in pain control.
