摘要:
This invention relates to a pharmaceutical dosage unit composition consisting essentially of a gelatin capsule containing (1) a disintegrating core comprising clonidine, said disintegrating core having a readily water-soluble coating, and (2) a plurality of non-disintegrating cores comprising clonidine, said non-disintegrating cores having a coating consisting of from 20 to 90 percent by weight of a water-insoluble film former and from 10 to 80 percent by weight of a water-soluble polymer, the diameter of each of the disintegrating and non-disintegrating cores being at least about 5 mm.
摘要:
A pharmaceutical dosage unit retard form having a constant, pH-independent release rate of active ingredient, consisting of a core comprising an active ingredient, and a semi-permeable diffusion coating over the core, were the coating consists of a water-insoluble film-former, a water-soluble polymer and eventually an acid-insoluble polymer incorporated therein.
