I et studie med intravenøs infusion af iloprost har patienter med nyreinsufficiens i slutstadiet, der gennemgik regelmæssig dialysebehandling, vist sig at have en signifikant lavere clearance (middel CL = 5 ± 2 ml/ minut/ kg) end observeret hos patienter med nyresvigt, som ikke gennemgik regelmæssig dialysebehandling (middel CL = 18 ± 2 ml/ minut/ kg).
In a study with intravenous infusion of iloprost, patients with end-stage renal failure undergoing intermittent dialysis treatment are shown to have a significantly lower clearance (mean CL = 5 ± 2 ml/ minute/ kg) than that observed in patients with renal failure not undergoing intermittent dialysis treatment (mean CL = 18 ± 2 ml/ minute/ kg).
