Abstract
The present invention is directed to compressed hemostatic tablets or forms comprising a fibrous non-woven oxidized cellulose (OC or ORC) multilayer material compressed into a form stable tablet, further comprising calcium salt, with the tablets rapidly expandable on contact with blood or blood plasma. The compressed forms may further comprise a multi-arm PEG-SG and are dimensionally, preferably with regard to length and width, stable for at least 48 hours after compression. In some embodiments, the compressed forms will expand upon contact with blood from 1.5 to 5 times of tablet length in 5 seconds; from 2 to 6 times of tablet length in 20 seconds; and from 3 to 6 times of tablet length in 5 minutes. The compressed forms are effective in hemostasis in heparinized blood.
