A method for preventing thrombosis in a setting where rapid onset and/or rapid offset of anticoagulation is required, comprising administering a compound selected from the group consisting of boronic acids which have a neutral thrombin P1 domain linked to a hydrophobic moiety capable of binding to the thrombin S2 and S3 subsites, and pharmaceutically acceptable salts, prodrugs and pharmaceutically acceptable prodrug salts of such acids.
A thrombin inhibitor selected from boronic acids of formula (I), and salts, prodrugs and prodrug salts thereof: wherein X is H (to form NH
