| Popis: | To further reduce the risk of possible viral disease transmission, an additional virucidal step was performed in the manufacturing process of a solvent/detergent treated factor VIII concentrate, which consisted of heating the lyophilized preparation at 100 degrees C for 30 min (Emoclot DI; ISI, Italy). Because thermal treatment may modify factor VIII bioavailability, the pharmacokinetic parameters and the acute tolerance of the single viral inactivated concentrate (preparation A) were compared with that of the double viral inactivated one (preparation B). Fifteen patients with severe haemophilia A and positive for HAV Ab were enrolled in a double-blind cross-over study and injected with 32.5 IU kg-1 of preparation A and 27 IU kg-1 of the preparation B. No significant differences between terminal half-life, area under the curve/dose, clearance/kg, volume of distribution at the steady state, in vivo recovery and acute tolerance of the two preparations was observed. The only statistical difference was restricted to Cmax. |
