Use
Attapulgite is widely used as an adsorbent in solid dosage forms.
Colloidal clays (such as attapulgite) absorb considerable amounts of
water to form gels and in concentrations of 2–5% w/v usually form
oil-in-water emulsions. Activated attapulgite, which is attapulgite
that has been carefully heated to increase its absorptive capacity, is
used therapeutically as an adjunct in the management of diarrhea.
