Abstract

Methods for forming implantable compositions are provided. In some embodiments, the methods include (i) providing a gel base, (ii) adding water and a hydrating agent to the gel base to form a mixture, (iii) reducing the water content of the mixture; and (iv) adding a delivered material before, during, and/or after step (ii) or (iii). The water content is reduced to about 5% or less by weight of the implantable composition.
