PCT No. PCT/EP93/03261 Sec. 371 Date Sep. 30, 1994 Sec. 102(e) Date Sep. 30, 1994 PCT Filed Nov. 20, 1993 PCT Pub. No. WO94/12218 PCT Pub. Date Jun. 9, 1994A conjugate of an antiviral nucleoside with a lactosaminated human albumin (L-HSA) and its method of preparation is described. The method of preparation involves the reaction of an antiviral phosphorylated nucleoside in the form of an imidizolide with L-HSA at a pH above 7.5 and running the reaction until the desired molar ratio of drug to L-HSA is obtained.
