INITIAL STEP THERAPY If the patient has filled a prescription for at least a 30 day supply of regular-release generic gabapentin within the past 120 days under a prescription benefit administered by CVS/caremark, then the requested Gralise, Horizant, Lyrica, or Lyrica CR will be paid under that prescription benefit. If the patient does not meet the initial step therapy criteria, then the system will reject with a message indicating that a prior authorization (PA) is required. The prior authorization criteria would then be applied to requests submitted for evaluation to the PA unit. COVERAGE CRITERIA The requested drug will be covered with prior authorization when the following criteria are met: The patient has experienced an inadequate treatment response, intolerance, or contraindication to regular- release generic gabapentin OR Lyrica (pregabalin) or Lyrica CR (pregabalin extended-release) is being prescribed for the management of neuropathic pain associated with diabetic peripheral neuropathy OR Lyrica (pregabalin) is being prescribed for the management of fibromyalgia, the management of neuropathic pain associated with diabetic peripheral neuropathy, or the management of neuropathic pain associated with spinal cord injury OR Horizant (gabapentin enacarbil) is being prescribed for the treatment of Restless Legs Syndrome RATIONALE If the patient has filled a prescription for at least a 30 day supply of regular-release generic gabapentin within the past 120 days under a prescription benefit administered by CVS/caremark, then the requested drug will be paid under that prescription benefit. If the patient does not meet the initial step therapy criteria, then prior authorization is required. The intent of the criteria is to provide coverage consistent with product labeling, FDA guidance, standards of medical practice, evidence-based drug information, and/or published guidelines. Gralise (gabapentin extended-release) is indicated for the management of postherpetic neuralgia (PHN).1 Horizant extended-release (gabapentin enacarbil extended-release) tablets are indicated for the treatment of moderate-to-severe primary Restless Legs Syndrome (RLS) in adults. Horizant extended-release (gabapentin enacarbil extended-release) tablets are also indicated for the management of postherpetic neuralgia in adults.2 Lyrica (pregabalin) is indicated for management of neuropathic pain associated with diabetic peripheral neuropathy, management of postherpetic neuralgia (DPN), adjunctive therapy for the treatment of partial onset seizures in patients 4 years of age and older, management of fibromyalgia (FM), and management of neuropathic pain associated with spinal cord injury.3 Lyrica CR (pregabalin extended-release) is indicated for the management of neuropathic pain associated with diabetic peripheral neuropathy (DPN) and management of postherpetic neuralgia (PHN).4 Gabapentin (regular-release) is indicated for management of postherpetic neuralgia in adults. Gabapentin (regular- release) is also indicated as adjunctive therapy in the treatment of partial seizures, with and without secondary generalization, in adults and pediatric patients 3 years and older with epilepsy.7 According to the Report of the Quality Standards Subcommittee of the American Academy of Neurology, gabapentin is effective in the reduction of pain from postherpetic neuralgia.11 Likewise, the American Academy of Neurology and American Epilepsy Society, state that gabapentin is appropriate for adjunctive treatment of refractory partial seizures in adults and children.15 Gabapentin has also shown to have analgesic effects in many cases of neuropathic pain Lyrica, Gralise, Horizant Step Therapy 656-D 05-2018 ©2018 CVS Caremark.

NCCN Guidelines for Adult Cancer Pain also state that neuropathic pain may be an adverse effect of chemotherapy (e.g., vincristine) or radiation therapy. The most commonly employed anticonvulsant drugs for the treatment of cancer pain are gabapentin and pregabalin.12 Therefore, a trial of regular-release generic gabapentin will be required for the diagnosis of postherpetic neuralgia prior to approval of Gralise, Horizant, Lyrica, or Lyrica CR, for cancer related neuropathic pain or cancer treatment related neuropathic pain prior to approval of Lyrica or Lyrica CR, or for the diagnosis of partial onset seizures prior to the approval of Lyrica. The American Academy of Neurology, the American Association of Neuromuscular and Electrodiagnostic Medicine, and the American Academy of Physical Medicine and Rehabilitation guideline for painful diabetic neuropathy states that Lyrica (pregabalin) is established as effective and should be offered, if clinically appropriate, for the relief of diabetic peripheral neurophathy.9 The American Diabetes Association recommends that pregabalin should be considered as the initial approach in the symptomatic treatment for neuropathic pain in diabetes.13 Therefore, Lyrica (pregabalin) or Lyrica CR (pregabalin extended-release) will be approved for the management of neuropathic pain associated with diabetic peripheral neuropathy without requiring a trial of regular-release generic gabapentin. There are varying levels of evidence for the use of gabapentin for the treatment of fibromyalgia, Restless Legs Syndrome, and neuropathic pain with spinal cord injury.8-14 Therefore, Lyrica will be approved for the diagnosis of fibromyalgia and neuropathic pain with spinal cord injury and Horizant will be approved for the diagnosis of Restless Legs Syndrome without requiring a trial of regular-release generic gabapentin. The efficacy of Lyrica CR has not been established for the management of fibromyalgia. REFERENCES 1. Gralise [package insert]. North Chicago, IL: Abbott Laboratories; September 2015. 2.

  • Chapter 25 Mechanisms of Action of Antiepileptic Drugs
    Chapter 25 Mechanisms of action of antiepileptic drugs GRAEME J. SILLS Department of Molecular and Clinical Pharmacology, University of Liverpool _________________________________________________________________________ Introduction The serendipitous discovery of the anticonvulsant properties of phenobarbital in 1912 marked the foundation of the modern pharmacotherapy of epilepsy. The subsequent 70 years saw the introduction of phenytoin, ethosuximide, carbamazepine, sodium valproate and a range of benzodiazepines. Collectively, these compounds have come to be regarded as the ‘established’ antiepileptic drugs (AEDs). A concerted period of development of drugs for epilepsy throughout the 1980s and 1990s has resulted (to date) in 16 new agents being licensed as add-on treatment for difficult-to-control adult and/or paediatric epilepsy, with some becoming available as monotherapy for newly diagnosed patients. Together, these have become known as the ‘modern’ AEDs. Throughout this period of unprecedented drug development, there have also been considerable advances in our understanding of how antiepileptic agents exert their effects at the cellular level. AEDs are neither preventive nor curative and are employed solely as a means of controlling symptoms (i.e. suppression of seizures). Recurrent seizure activity is the manifestation of an intermittent and excessive hyperexcitability of the nervous system and, while the pharmacological minutiae of currently marketed AEDs remain to be completely unravelled, these agents essentially redress the balance between neuronal excitation and inhibition. Three major classes of mechanism are recognised: modulation of voltage-gated ion channels; enhancement of gamma-aminobutyric acid (GABA)-mediated inhibitory neurotransmission; and attenuation of glutamate-mediated excitatory neurotransmission. The principal pharmacological targets of currently available AEDs are highlighted in Table 1 and discussed further below.

Lebedyeva Faculty Sponsor(s): Iryna O. Lebedyeva, PhD Affiliation(s): Department of Chemistry and Physics (Augusta Univ.) ABSTRACT A number of blood and brain barrier penetrating neurotransmitters contain polar functional groups. Gamma-aminobutyric acid (GABA) is an amino acid, which is one of the primary inhibitory neurotransmitter in the brain and a major inhibitory neurotransmitter in the spinal cord. Antiepileptic medications such as Gabapentin, Phenibut, and Pregabalin have been developed to structurally represent GABA. These drugs are usually prescribed for the treatment of neuropathic pain. Since these drugs contain a polar carboxylic acid group, it affects their ability to penetrate the blood and brain barrier. To address the low bioavailability and tendency for intramolecular cyclization of Gabapentin, its less polar prodrug Gabapentin Enacarbil has been approved in 2011.

Typically, neuropathic pain is difficult to manage and, as a result, leads to progression into a chronic condition that is, in many instances, refractory to medical management. Recent Findings Gabapentinoids, belonging to the calcium channel blocking class of drugs, have shown good efficacy in the management of chronic pain and are thus commonly utilized as first-line therapy. Various sodium channel blocking drugs, belonging to the categories of anticonvulsants and local anesthetics, have demonstrated varying degrees of efficacy in the in the treatment of neurogenic pain. Summary Though there is limited medical literature as to efficacy of any one drug, individualized multimodal therapy can provide significant analgesia to patients with chronic neuropathic pain.

  • Gabapentinoids: Pharmacokinetics, Pharmacodynamics and Considerations for Clinical Practice
    912496BJP British Journal of PainChincholkar Special Issue Article British Journal of Pain 1 –11 Gabapentinoids: pharmacokinetics, © The British Pain Society 2020 Article reuse guidelines: sagepub.com/journals-permissions pharmacodynamics and considerations DOI:https://doi.org/10.1177/2049463720912496 10.1177/2049463720912496 for clinical practice journals.sagepub.com/home/bjp Mahindra Chincholkar Abstract The gabapentinoids are often recommended as first-line treatments for the management of neuropathic pain. The differing pharmacodynamic and pharmacokinetic profiles can have implications for clinical practice. This article has summarised these key differences. In addition to their use in managing neuropathic pain, gabapentinoids are increasingly being used for off-label conditions despite the lack of evidence. Prescription rates for off-label conditions have overtaken that for on-label use. Similarly, the use of gabapentinoids in the perioperative period is now embedded in clinical practice despite conflicting evidence. This article summarises the risks associated with this increasing use. There is increasing evidence of the potential to cause harm in vulnerable populations such as the elderly and increasing prevalence of abuse. The risk of respiratory depression in combination with opioids is of particular concern in the context of the current opioid crisis. This article describes the practical considerations involved that might help guide appropriate prescribing practices.
