Abstract (en)

[origin: WO2010077156A1] The composition for the prolonged release of heparin, wherein the gel obtained from the alkali metal alginate and hydroxypropylcellulose at the weight ratio from 2:1 to 5:1 is used subjected to the gelling process using calcium salt, containing immobilised heparin in the amount from 0.01 to 10% w/w. The invention also relates to the use of the gel obtained from sodium alginate and hydroxypropylcellulose for the prolonged release of heparin.
