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 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. Medscape - Seizure dosing for Neurontin, Gralise (gabapentin), frequency-based adverse effects, comprehensive interactions, contraindications, pregnancy & lactation schedules, and cost information. CrCl <15 mL/minute: Reduce daily dose in proportion to creatinine clearance based on dose for creatinine clearance of 15 mL/minute (eg, reduce dose by one-half [range: 50 to 150 mg/day] for CrCl 7.5 mL/minute) ESRD requiring hemodialysis: Dose based on CrCl plus a single supplemental dose of 125 to 350 mg (given after each 4 hours of hemodialysis 5. Peadiatric Renal Dosing For Children: Kidney Function: If a child has kidney problems, the dose needs to be lower. Ages ≥12 years: Adjust based on creatinine clearance and weight. Dosage Adjustment: Lower doses required; consult a paediatric specialist. 6. Administration How to Take Gabapentin: Gabapentin Capsules/Extended-Release: The mean gabapentin half-life ranged from about 6.5 hours (patients with creatinine clearance >60 mL/min) to 52 hours (creatinine clearance <30 mL/min) and gabapentin renal clearance from about 90 mL/min (>60 mL/min group) to about 10 mL/min (<30 mL/min). 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. Creatinine clearance (CLCr) is difficult to measure in outpatients. In patients with stable renal function, creatinine clearance can be reasonably well estimated using the equation of Cockcroft and Gault: The use of gabapentin in patients less than 12 years of age with compromised renal function has not been studied. 2.4 Dosage in Elderly Because elderly patients are more likely to have Absorption of gabapentin is solely dependent on LAT that are easily saturable, resulting in dose-dependent pharmacokinetics. As the dose of gabapentin increases, the area under the plasma concentration–time curve (AUC) does not increase proportionally. 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. The exact renal dosing for gabapentin is not specified in the provided studies, but it is recommended to use gabapentin judiciously in patients with decreased kidney function and to consider dosage adjustments based on the patient's creatinine clearance (CrCl) 4, 5. Gabapentin elimination rate constant, plasma clearance, and renal clearance are directly proportional to creatinine clearance. In elderly patients, and in patients with impaired renal function, gabapentin plasma clearance is reduced. Gabapentin elimination rate constant, plasma clearance, and renal clearance are directly proportional to creatinine clearance (see Special Populations: Patients With Renal Insufficiency, below). View gabapentin information, including dose, uses, side-effects, renal impairment, pregnancy, breast feeding, monitoring requirements and important safety information. For neuropathic pain, a standard dosage pattern is used, typically recommending a dose three times daily. For epilepsy, the tool provides a dosage range within specific limits. Adjustments are made according to kidney function using the patient’s creatinine clearance value. Neurontin - Gabapentin Renal Dosing protocol for Adults, maintenance gabapentin dosing and additional dosing for adults undergoing dialysis Kidney disease alters the pharmacokinetic disposition of many medications, requiring dosage adjustment to maintain therapeutic serum concentrations. The Cockcroft-Gault (CG) equation is used for pharmacokinetic studies and drug dosage adjustments, but the Modification of Diet in Renal Disease (MDRD) Study equation is more accurate and more often reported by clinical laboratories than the CG Table 3. Gabapentin Dosage Guidelines in Adults, Adolescents 12 Years of Age and Older with Renal Impairment 1-5; Creatinine Clearance (CrCl) Recommended Dosage Adjustments; Gabap For patients with creatinine clearance <15 mL/min, reduce daily dose in proportion to creatinine clearance (e.g., patients with a creatinine clearance of 7.5 mL/min should receive one-half the daily dose that patients with a creatinine clearance of 15 mL/min receive). Dosage adjustment in patients 12 years of age and older with compromised renal function or undergoing hemodialysis is recommended, as follows (see dosing recommendations above for effective doses in each indication): TABLE 1.
