Hos patienter over 75 år, der gennemgik ortopædkirurgi og fik 2, 5 mg fondaparinux en gang daglig, blev plasmaclearance vurderet til 1, 2 til 1, 4 gange lavere end hos patienter under 65 år.
In patients > 75 years undergoing orthopaedic surgery and receiving fondaparinux 2.5 mg once daily, the estimated plasma clearance was 1.2 to 1.4 times lower than in patients < 65 years.
