ABSTRACT:
The use of crosslinked polysaccharides as vehicles for spermicidal substances in compositions used for local contraception is described. The crosslinked polysaccharide (e.g. a modified dextran) is admixed with the spermicidal agent and formed into tablets for vaginal applications; the dextran swells in contact with the vaginal secretion and includes the seminal liquid thus bringing into contact the sperm cells with the spermicidal substances dispersed therein.
