Download Table | Recommended dose adjustments based on varying degrees of renal impairment from publication: Rational dosing of gabapentin and pregabalin in chronic kidney disease | Mena Raouf,1 Gabapentin and pregabalin are used for neuropathic pain in CKD patients but require renal adjustments. Per Lexicomp, Gabapentin’s recommended dose in patients with renal impairment is as follows: CrCl >15 to 29 mL/minute: 200 to 700 mg once daily. CrCl 15 mL/minute: 100 to 300 mg once daily. INTRODUCTION Pain is one of the most common and distressing symptoms among patients with chronic kidney disease (CKD) [1]. The prevalence of pain has been associated with substantially lower health-related quality of life and greater psychosocial distress, insomnia, and depressive symptoms [2-9]. Among hemodialysis patients, severe pain is also independently associated with shortened or missed Introduction Renal dose adjustments for gabapentin and pregabalin are ubiquitously evident in the medical literature. All manufacturers for these branded and generic dosage forms list dosing recommendations relative to creatinine clearance (CrCl) for both medications (Table 1).1,2 However, the basis of these recommendations has not been well articulated. Rational dosing of gabapentin and pregabalin in chronic kidney disease Mena Raouf,1 Timothy J Atkinson,1 Meredith W Crumb,1 Jeffrey Fudin2–5 1VA Tennessee Valley Healthcare System, Murfreesboro, Nashville, TN, 2Stratton VA Medical Center, 3Albany College of Pharmacy and Health Sciences, Albany, NY, 4Western New England University College of Pharmacy, Springfield, MA, 5Scientific and Clinical 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. 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’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. Usual initial gabapentin dose: 300mg q8h. Usual maintenance dose: 300-600mg q8h. Maximum dosage/day: 3600 mg. [15-29]: Dosage range: 200-700mg/day. [<15]: 100-300 mg/day. Use lower end of this range for CRCL <7.5 ml/min. TABLE 1. Gabapentin Dosage Based on Renal Function. TID = Three times a day; BID = Two times a day; QD = Single daily dose. a. 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). Table 1 shows maximum recommended dose of gabapentin in renal impairment: Table 2 shows the maximum recommended dose of pregabalin in renal impairment: In this scenario you are carrying out an audit of gabapentinoid prescribing in your work area, to ensure that the doses prescribed in renal impairment are safe and appropriate. Dose as in GFR=15–30 mL/min Potentially hazardous interactions with other drugsAntacids: reduce absorption Antidepressants: antagonism of anticonvulsive effect (convulsive threshold lowered) Discussion. 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. We describe a patient who developed significant deterioration in her conscious level due to iatrogenic gabapentin overdose. Conclusion. Chronic kidney disease affects renal drug elimination and other pharmacokinetic processes involved in drug disposition (e.g., absorption, drug distribution, nonrenal clearance [metabolism]). Drug Gabapentin dosing in patients with renal impairment should be adjusted based on creatinine clearance (CrCl) to minimize the risk of toxicity and optimize efficacy. There is no indication that gabapentin on its own can cause renal impairment, renal failure, or kidney disease. However, if you already have kidney disease, it may be more difficult to clear gabapentin from your system, which means that your dose will have to be adjusted accordingly. Gabapentin Dosage Guidelines in Adults, Adolescents 12 Years of Age and Older with Renal Impairment 1-5. For adults with normal kidneys: Nerve Pain/Restless Leg Syndrome: Start 300 mg once daily, increase to 300 mg 3 times a day. Max: 3600 mg per day. Seizures: Start with 300 mg 3 times a day, then increase to 600 mg 3 times a day. 4. Renal Dosing Recommendations. Dose Adjustment: 900 - 3600 mg/day TID. How Often to Take: 3 times a day. The recommended maximal daily dose of gabapentin is 1,500 mg in people with grade 3 chronic kidney disease (CKD), 700 mg in those with grade 4 CKD, 300 mg in those with grade 5 CKD, and 100 to 300
