Pharmaceutical compositions capable of being gelled

摘要

A method is described for preparing a fluid pharmaceutical composition which allows the controlled release of at least one active substance. The method involves mixing a therapeutically effective amount of at least one active substance, from 3 to 55% by weight of phospholipid, from 16 to 72% by weight of pharmaceutically acceptable solvent, and from 4 to 52% by weight of fatty acid. The composition has a property of gelling instantaneously in the presence of an aqueous phase.
