Medication | Percent excreted in the urine | T one-half normal (hours) | T one-half dialysis (ESKD) (hours) | Hemodialysis | Peritoneal dialysis | Comments and recommendations on use in advanced CKD* |
Acetaminophen (paracetamol)[1-4] | <5 | 1 to 4 | Unchanged | Dialyzed | Not dialyzed | Accumulation of inactive metabolites. Analgesic of choice for mild-moderate pain. No dose reduction required. |
Codeine[5-7] | 0 to 16 | 2.5 to 4 | 13 to 18.9 | Not dialyzed | Unlikely to be dialyzed | Metabolized to morphine derivatives and known to cause profound hypotension and CNS and respiratory depression. Not recommended in advanced CKD. |
Tramadol[8-10] | 90 (30 unchanged; 60 as metabolites) | 6 | 11 | Dialyzed | Unknown | Unpredictable risk of serious overdosing or underdosing after administration of standard doses. Not recommended in advanced CKD. |
Morphine | 10 | 2 to 3 | Unchanged | Parent and active metabolites dialyzed | Not dialyzed | Rapid accumulation of active metabolites in advanced CKD resulting in clinically significant opioid toxicity including sedation, confusion, myoclonus, and respiratory depression. Not recommended in advanced CKD. |
Hydromorphone[11,12] | 6 | 2 to 5 | 3.2 on dialysis; 5.9 nondialysis days | Active metabolite (H3G) dialyzed | Unknown | Much better tolerated in advanced CKD than morphine with less toxic metabolites. Pharmacodynamic data have shown less neuroexcitation compared with morphine and a greater than 65% reduction in pain over dosing intervals with no clinically significant opioid toxicity when given in low doses and monitored carefully. |
Fentanyl[13] | <7 | 2 to 7 | Possibly increased | Not dialyzed | Not dialyzed | Inactive metabolites. Most pharmacokinetic studies in advanced CKD use parenteral rather than transdermal fentanyl. Generally considered safe for use in advanced CKD if monitored carefully. |
Alfentanil[14] | 0.4 | 1 to 2 | Unchanged | Not dialyzed | Not dialyzed | Although pharmacokinetics of fentanyl analogs alfentanil and sufentanil do not appear to differ in advanced CKD, there is a single case report of prolonged respiratory depression in a patient with ESKD where there was an elevated plasma concentration of sufentanil. |
Buprenorphine[15-18] | Minimal | 30 | Unchanged | Dialyzed | Dialyzed | Buprenorphine may be given in standard doses to patients with advanced CKD. Generally considered safe for use in advanced CKD if monitored carefully. |
Oxycodone[19-22] | <10 | 2 to 4 | 3 to 5 | Dialyzed | Unknown | There are case reports of toxicity in association with advanced CKD, yet overall consensus from the literature is that oxycodone is reasonably safe to use in advanced CKD if monitored carefully. |
Methadone[23,24] | 15 to 60 | 13 to 47 | Unknown | Not dialyzed | Not dialyzed | Primarily excreted in the feces. Plasma concentrations are similar in advanced CKD compared with those with normal kidney function. Generally considered safe for use in advanced CKD if monitored carefully. |
Gabapentin[25-27] | Approximately 100 | 5 to 7 | 52 to 132 | Dialyzed | Possibly dialyzed | Freely crosses the blood-brain barrier. Dose postdialysis. The following are maximum doses:
|
Pregabalin[28,29] | 92 to 99 | 5 to 6.5 | Increased | Dialyzed (50% dialyzed in four hours) | Dialyzed | Similar mechanism of action as gabapentin. Can give supplementary dose postdialysis (75 mg). Dose regimen equivalent to approximately 600 mg per day of pregabalin in patient with normal kidney function:
|
Carbamazepine[30] | 3 to 5 | 35 | Unchanged | Dialyzed | Unknown | Start at 100 mg daily or twice daily and increase by 100 mg daily to a maximum of 1200 mg daily. |
Duloxetine[6,31] | <1 | 8 to 17 | Unchanged | Not dialyzed | Not dialyzed | Reduced starting dose in advanced CKD (30 mg) with a maximum dose of 60 mg per day. Some sources recommend avoiding in patients with a CrCl of <30 mL/min. Others suggest starting at a very low dose and increase according to response, with a maximum dose of 30 mg daily. |
Ketamine[6] | 2 to 4 | 2 to 4 | Unchanged | Not dialyzed | Unlikely to be dialyzed | Dose as per normal kidney function. |
Amitriptyline[32,33] | <2 | 9 to 25 | Unchanged | Not dialyzed | Not dialyzed | Although no dose reduction is required, a low starting dose is recommended given likelihood of anticholinergic adverse effects. |
