Efter gentagen dosering af ritanovir til raske frivilige (500 mg to gange daglig) og patienter med mild til moderat svækket leverfunktion (400 mg to gange daglig) var dosiseksponeringen af ritanovir efter normaliseing af dosis ikke signifikant forskellig i de to grupper.
Patients with impaired liver function: after multiple dosing of ritonavir to healthy volunteers (500 mg twice daily) and subjects with mild to moderate hepatic impairment (Child Pugh Class A and B, 400 mg twice daily) exposure to ritonavir after dose normalisation was not significantly different between the two groups.
