TID = Three times a day; BID = Two times a day; QD = Single daily dose. a 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). Hemodialysis (CrCl ; 15 mL/min): Administer supplemental dose (range 125-350 mg) posthemodialysis, after each 4 hr dialysis interval; further dose reduction should be in proportion to CrCl (eg, CrCl of 7.5 mL/min should receive one-half daily posthemodialysis dose) 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). 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. Levels of Kidney Problems: Mild Kidney Problems: Kidneys are a little slow (Creatinine Clearance [CrCl] 60-89 ml/min) 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. 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 (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). Renal function (creatinine clearance mL/min) Maximum daily dose mg (in 3 divided doses) ≥80: 3600 50-79: 600-1800: 30-49: 300-900: 15-29: 150-600 (150 mg daily dose to be given as 300 mg in 3 divided doses on alternate days) 15: 150-300 (150 mg daily dose to be given as 300 mg in 3 divided doses on alternate days). Further dose reductions may Gabapentin dosing guidelines for adult with renal impairment are summarized in Table 3. Dosing guidelines for gabapentin immediate-release are also applicable for adolescents 12 years of age and older with renal impairment. Pregabalin’s apparent total clearance is 67–81 mL/min in young healthy subjects and is therefore thought to undergo tubular reabsorption to some extent. 2 Hemodialysis (HD) removes approximately 35% of gabapentin and 50%–60% of pregabalin, where supplemental doses are generally recommended post-HD. 1, 2 Dose recommendations in relation to renal function given in the SPCs are in general based on endogenous creatinine clearance or estimated creatinine clearance according to the CG equation (including P-creatinine, age, sex and weight) in ml/min, an absolute value of clearance.1 This is also the case for dabigatran.38 However, different equations 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) Manufacturer advises reduce dose to 150‒300 mg daily in 3 divided doses if creatinine clearance is less than 15 mL/minute (150 mg daily dose to be given as 300 mg in 3 divided doses on alternate days)—further dose reductions may be required in proportion to creatinine clearance, consult product literature. 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 . 1,2 However, the basis of these recommendations has not been well articulated. Dosage adjustment in patients 12 years of age and older with renal impairment or undergoing hemodialysis is recommended, as follows (see dosing recommendations above for effective doses in each indication): TABLE 1. Gabapentin Dosage Based on Renal Function Renal Function Creatinine Clearance (mL/min) Total Daily Dose Range (mg/day) Dose In the presence of cimetidine at 300 mg four times a day (N=12), the mean apparent oral clearance of gabapentin fell by 14% and creatinine clearance fell by 10%. Thus, cimetidine appeared to alter the renal excretion of both gabapentin and creatinine, an endogenous marker of renal function. Gabapentin elimination half-life is 5 to 7 hours and is unaltered by dose or following multiple dosing. Gabapentin elimination rate constant, plasma clearance, and renal clearance are directly When creatinine clearance is below 30 mL/minute, the half-lives of both gabapentin and pregabalin are prolonged. 8 For people with CKD, starting gabapentin at 300 mg or more daily, or pregabalin Objective: To determine whether patients with decreased creatinine clearance (CrCl) experienced increased frequency of AEs related to gabapentinoid dose at hospital admission. Methods: Single-center retrospective cohort study in adults with a gabapentinoid prescription and serum creatinine measurement documented on hospital admission. TID = Three times a day; BID = Two times a day; QD = Single daily dose. a 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).
