Enteric soft capsules containing carrageenans as the film-forming polymer have been developed. The enteric soft capsules comprise iota carrageenan and kappa carrageenan, methacrylic acid copolymers, modifeid starch fillers, plasticizers, water, and other excipients. Such enteric soft capsules are stable at pH 1.2 for at least 2 hours and dissolve at pH 6.8 within about 30 minutes. Methods for manufacturing enteric soft capsules comprising carrageenans are also exemplified.
