ABSTRACT:
Microporous polylactide powders having an intrinsic isotropic structure being spherical in a shape and containing interconnecting hollow spaces or openings i.e., micropores are obtained by the steps of heating a polylactide in xylene until substantially complete solution is reached; cooling the resultant clear solution; and separating off the xylene.
The microporous powder form powders can have active substances such as a medicament introduced therein i.e. unto the pores and the resultant powder can be used for controllably dispensing the medicament i.e., as a prolonged release form.
