Expandable hemostatic tablets comprising oxidized regenerated cellulose

A compressed hemostatic form having a longitudinal axis and a length as measured along the axis comprising:

• a) a fibrous non-woven oxidized cellulose (OC) multilayer material compressed into a form stable tablet, and
• b) a calcium salt,
• wherein said tablet rapidly expands along at least the longitudinal axis on contact with liquid blood plasma,
• wherein
• (i) said tablet has a tablet length from 3 to 10 mm, and
• (ii) (ii) said tablet expands, upon contact with blood or blood plasma, from 1.5 to 5 times of said tablet length in 5 seconds;
• or from 2 to 6 times of said tablet length in 20 seconds;
• or from 3 to 6 times of said tablet length in 5 minutes, and
• wherein said form is made by compressing a stack of non-woven OC material in presence of a 10%-20% calcium salt solution in ethanol, followed by drying under vacuum and evaporating said ethanol.
