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. Gabapentinoids, including gabapentin and pregabalin, are frequently prescribed as opioid alternatives. Given that gabapentinoids are eliminated from the body by the kidney, we sought to determine the risk of serious adverse events in patients with chronic kidney disease who started a gabapentinoid at a higher versus a lower dose. Abstract Rationale & objective: 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. View gabapentin information, including dose, uses, side-effects, renal impairment, pregnancy, breast feeding, monitoring requirements and important safety information. CONCLUSION: Gabapentin toxicity in patients with chronic kidney disease is underrecognized. 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. Studies have shown that gabapentin toxicity can occur in patients with chronic kidney disease, particularly in those with advanced age and multiple comorbidities 4, 5. Dose Adjustment and Renal Function Dose adjustment of gabapentin is crucial in patients with decreased renal function to prevent toxicity 4, 5. Key takeaways Gabapentin is a medication used to treat seizures, postherpetic neuralgia pain associated with shingles, restless leg syndrome, and diabetic neuropathy. For people with normal kidney function, gabapentin is safe and doesn’t cause kidney complications or trigger kidney disease. Gabapentin’s apparent total clearance is 100 mL/min in adults with normal renal function, which is essentially equivalent to CrCl and does not suggest the involvement of tubular reabsorption. 1 Some evidence suggest that active tubular secretion mediated by organic cation transporter-1 (OCT-1) may play a role in gabapentin’s renal clearance. Abstract Background: 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. Existing literature on such risk is lacking. Conclusion Gabapentin toxicity in patients with chronic kidney disease is underrecognized. 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. 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. Objective: To determine whether patients with decreased creatinine 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. Neurontin - Gabapentin Renal Dosing protocol for Adults, maintenance gabapentin dosing and additional dosing for adults undergoing dialysis Impaired kidney function (reduced creatinine clearance) increases drug accumulation, raising side effects risk. So, it's important to change the dose if your kidneys aren't working right. Gabapentin doesn’t hurt the liver or kidneys in most cases. However, taking a safe gabapentin dose is important to prevent potential side effects. Gabapentin and pregabalin are often used in patients with CKD primarily to treat neuropathic pain and restless leg syndrome and given the high prevalence of diabetes in this population, the proportion who receive these drugs is very high. 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 Gabapentin toxicity in patients with chronic kidney disease is underrecognized. Patients with chronic kidney disease often receive dangerously high gabapentin dosage for their kidney function, which can lead to all sorts of problems. Gabapentinoids, including gabapentin and pregabalin, are frequently prescribed as opioid alternatives. Given that gabapentinoids are eliminated from the body by the kidney, we sought to determine the risk of serious adverse events in patients with chronic kidney disease who started a gabapentinoid at a higher versus a lower dose. It is essential that a patient's renal function is taken into account when prescribing and reviewing medication. Doses often need to be reduced in renal impairment to prevent accumulation and toxicity. Examples of drugs that should be reduced in renal impairment are the gabapentinoids: gabapentin and pregabalin. Table 1 shows maximum recommended dose of gabapentin in renal impairment: Table 2 Reaching a certain therapeutic concentration of gabapentin is inevitable to achieve the desirable effect, which makes its usage more challenging especially in patients with impaired renal function given its 100% renal clearance.
