Fosnetupitant/palonosetron Disease Interactions

Limited data are available with fosnetupitant (only available in combination with palonosetron in the US) in patients with severe hepatic impairment (Child-Pugh score greater than 9), therefore, its use should be avoided in these patients. No dosage adjustment is necessary for patients with mild to moderate hepatic impairment (Child-Pugh score 5 to 8).

No dosage adjustment for netupitant/fosnetupitant (only available in combination with palonosetron in the US), is necessary in patients with mild to moderate renal impairment (creatinine clearance of 30 to 60 mL/min). The pharmacokinetics and safety of netupitant/fosnetupitant have not been studied in patients with severe renal impairment. Severe renal impairment (creatinine clearance < 30 mL/min) did not substantially affect pharmacokinetics of palonosetron. The pharmacokinetics for netupitant and palonosetron were not studied in patients with end-stage renal disease requiring hemodialysis, therefore, avoid the use of this drug in patients with severe renal impairment or end-stage renal disease.

Mild to moderate renal impairment does not significantly affect palonosetron pharmacokinetic parameters. However, total systemic exposure increased approximately 28% in patients with severe renal impairment. Additionally, the pharmacokinetics of palonosetron have not been studied in patients with end-stage renal disease. Caution is advised.

No dosage adjustment for palonosetron is necessary for patients with mild to moderate hepatic impairment (Child-Pugh score 5 to 8). Limited data are available in patients with severe hepatic impairment (Child-Pugh score greater than 9). It is recommended to avoid use of palonosetron in patients with severe hepatic impairment.
