Abstract Background: Gabapentin and pregabalin are well-tolerated medications primarily cleared by the kidney. Patients receiving higher gabapentinoid doses with decreased kidney function may be at an increased risk of adverse effects (AEs), but limited evidence exists evaluating gabapentinoid dosing and AEs in this population. Gabapentin is frequently used as an analgesic in patients with chronic kidney disease. Although gabapentin is well known for its favorable pharmacokinetics, it is exclusively eliminated renally, and patients with chronic kidney disease are at risk for toxicity. Unlike other drugs, gabapentin is not metabolized in the liver and is solely excreted by the kidneys. Therefore, it is crucial to adjust the dosage in patients with renal insufficiency to avoid severe adverse effects. When kidney function declines, the clearance of Gabapentin can be affected, leading to increased levels in the bloodstream. For patients with normal kidney function, Gabapentin's half-life—approximately 5 to 7 hours—allows for effective dosing without significant accumulation. In patients with normal renal function, the maximum dose of gabapentin is 3600mg daily in divided doses. However, gabapentin is renally cleared and so the dose needs to be adjusted according to the GFR. For patients on dialysis, the recommended dose is 100-300mg post dialysis on dialysis days only. Gabapentinoids are opioid substitutes whose elimination by the kidneys is reduced as kidney function declines. To inform their safe prescribing in older adults with chronic kidney disease (CKD), we examined the 30-day risk of serious adverse events according to the prescribed starting dose.

Gabapentin is an anticonvulsive that is widely used for a number of indications at present: diabetic neuropathy, neuropathic pain of other causes, epilepsy, etc. Some of its most common side effects include the following: ataxia, nystagmus, drowsiness, headaches, diplopia, fatigue and myoclonic twitches. 1 All of these effects appear quite often in patients with chronic kidney disease Gabapentin is an anticonvulsant with analgesic effects. It was approved by the Food and Drug Administration in 1994 as an adjunctive agent for partial seizures and subsequently in 2002 as an analgesic for postherpetic neuralgia. In recent years, gabapentin has been increasingly used off-label for expanded indications, including migraine headache,1 phan-tom limb pain,2 cancer-related pain,3 When it comes to gabapentin and kidney disease, kidney disease sufferers should be aware of the risks that are involved in taking gabapentin with kidney disease. Gabapentin is actually toxic to the kidneys. Gabapentin is frequently used as an analgesic in patients with chronic kidney disease. Similarly to the liver, there have been rare cases of kidney damage associated with Gabapentin use. Individuals with pre-existing kidney conditions or those taking other medications that can affect kidney function may be at a higher risk. To protect your kidneys while taking Gabapentin, consider the following recommendations: Abstract Background: Gabapentinoids (GPs) are frequently prescribed in individuals with chronic kidney disease (CKD); however, their exclusive renal elimination warrants dose adjustments to decrease risk of toxicity. This study evaluated GP prescribing patterns and whether excessive dosing was associated with increased incidence of gabapentinoid-related adverse events (GRAEs). Gabapentin (Neurontin, Horizant, Gralise) usually isn’t bad for your liver or kidneys. In most cases, it has no harmful effect on these organs. In rare instances, gabapentin can cause DRESS (drug reaction with eosinophilia and systemic symptoms) syndrome. Gabapentin can be removed from plasma by hemodialysis. Gabapentin affects kidney function as it is primarily eliminated by the kidneys and its clearance is directly proportional to creatinine clearance. This means that patients with impaired renal function may have reduced gabapentin clearance, leading to increased drug levels and potential Here’s a scenario of using gabapentin in chronic kidney disease. A 42 year old African American man with a history of coronary artery disease and decompensated heart failure s/p heart transplant and chronic kidney disease presented to a hospital on 9/29/16 complaining of shortness of breath, dyspnea upon exertion and LE edema. Pharmacology Gabapentin and pregabalin are commonly used first-line agents for diabetic peripheral neuropathy and other common neuropathies. Pharmacologically, both agents inhibit alpha-2-delta (α2δ) subunit of N-type voltage-gated calcium channels, a key receptor involved in regulating the excitability of neurons. 3 Peripheral nerve injury results in the upregulation of α2δ-1 receptors in For people with normal kidney function, gabapentin is safe and doesn’t cause kidney complications or trigger kidney disease. In people with renal impairment, gabapentin can be harder to clear from the body. Patients with chronic kidney disease often receive inappropriately high gabapentin dosage for their kidney function, occasioning overt toxicity; advanced age and comorbidity predispose these patients for toxicity. Gabapentin is widely used in the management of pain. It is entirely excreted through the renal system so this needs to be considered in any patient becoming acutely ill and developing renal failure. The FDA drug label does not directly answer whether gabapentin worsens renal function. However, it does indicate that gabapentin is substantially excreted by the kidney and that patients with impaired renal function are at a greater risk of toxic reactions.
