Randomized trials on pregabalin and gabapentin have shown their effectiveness on peripheral neuropathic pain reduction. Gabapentinoids are also indicated in the treatment of postherpetic neuralgia, central neuropathic pain and the neuropathic component of cancer pain. Although several different types of anticonvulsants have been shown to modulate neuropathic pain activity, the 2 most commonly used are gabapentin (Neurontin, others) and pregabalin (Lyrica). Both gabapentin and pregabalin pre-synaptically bind to the a2d-subunit on voltage-dependent calcium channels, modulating calcium influx and reducing Another option is gabapentin, which belongs to the same class of drugs as Lyrica but may have a different side effect profile. Understanding the gabapentin side effects in elderly patients can help determine if it’s a more suitable alternative. Background Older patients are typically underrepresented in clinical trials of medications for chronic pain. A post hoc analysis of multiple clinical studies of pregabalin in patients with painful diabetic peripheral neuropathy (DPN) or postherpetic neuralgia (PHN) was conducted to evaluate the efficacy and safety of pregabalin in older patients. Methods Data from 11 double-blind, randomized Gabapentin and pregabalin both require dose adjustment in individuals with reduced renal function. Consult the summary of product characteristics (SmPC) for gabapentin and pregabalin for further information before determining an equivalent dose and switching strategy.

Explore the connection between gabapentin and depression, mechanisms behind gabapentin-related depression, and strategies to manage and mitigate side effects. Discover other significant concerns for elderly gabapentin users and the importance of personalized An important difference between the two members of the gabapentinoid family is bioavailability; while the amount of gabapentin absorbed is dose dependent, pregabalin has a linear profile and is more than 90% bioavailable between doses of 25 mg and 300 mg (single dose). 32, 33 With gabapentin administered at low doses, high bioavailability is With gabapentinoids, increased risk of sedation, respiratory depression, and death. Overdose risk with benzodiazepines. Acceptable for recent acute severe pain such as fracture or joint replacement. Consider reducing other concomitant medication(s) that can cause falls. Employ fall-prevention strategies. occurrence of accidental injury (fall) in the elderly population4,5. • Gabapentin6 and pregabalin7 are associated with rare/infrequent risk of respiratory depression. The MHRA advises prescribers to show caution when initiating gabapentin or pregabalin and consider Gabapentin and pregabalin are similar drugs but differ in several distinct ways. The main differences are their indications—specific uses that the Food and Drug Administration (FDA) has approved them to treat—and their dosages. Examples of pain-relieving anti-seizure medications include gabapentin (Neurontin, Gralise) and pregabalin (Lyrica). Side effects of these medications are common and may include nausea, dizziness, drowsiness and a sense of tiredness. Pregabalin showed superior results compared to gabapentin in the Visual Analog Scale (VAS) at various time intervals up to 12–14 weeks (SMD −0.47, 95% CI −0.74 to −0.19). Gabapentin is indicated as adjunct therapy for partial seizures and postherpetic neuralgia. 4 Pregabalin is indicated for the same uses as gabapentin, plus the management of fibromyalgia and neuropathic pain associated with diabetes, specifically diabetic neuropathy. 5 Gabapentin and pregabalin are safe and efficacious options to treat older adults with chronic pruritus. Prior to gabapentinoid initiation, the patient should be screened for: history of kidney disease; COPD or other lung disorders; current opioid medication use; history of falls, lightheadedness, or vertigo; history of mood disorders, including depression and suicidal ideation; history of The main differences between Lyrica and gabapentin are: Lyrica is a brand name for pregabalin. Gabapentin is a generic name - brands of gabapentin include Neurontin, Gralise, and Horizant. Gabapentin is not the same as pregabalin, even though they both belong to the same class of medicine, called gabapentinoids, and work similarly Pregabalin and gabapentin are both FDA approved as an add-on treatment for partial-onset seizures. But pregabalin is approved for adults and children as young as 1 month old, whereas gabapentin is approved for adults and children who are at least 3 years old. Explore these related articles, suggested for readers like you. The general recommendation is to commence treatment with gabapentin/pregabalin or a tricyclic antidepressant (eg, amitriptyline or nortriptyline) and, in case of focal neuropathy, topical lidocaine. The choice between a gabapentinoid and a tricyclic is based on considerations on tolerability rather than quality or intensity of pain. Anticonvulsants: Antiepileptic drugs such as carbamazepine, gabapentin, and pregabalin are mainly used for neuropathic pain. In elderly patients with renal impairment, dose adjustment of gabapentin and pregabalin is required. Carbamazepine currently is the first line therapy for neuralgia. Ensure that gabapentin and pregabalin are prescribed at an appropriate place in therapy for neuropathic pain taking into consideration value for money. Ensure prescribed (and taken) doses of pregabalin and gabapentin are not outside the therapeutic dose range. Prescribing of pregabalin capsules should be optimised to the
