Manufacturing processes, drug absorption

The solvents used to dissolve the polymeric materials are chosen according to the polymer and drug solubilities and stabilities, process safety, and economic considerations. Substances can be incorporated within microspheres in the liquid or solid state during manufacture or subsequently by absorption. Fig. 1 shows two types of microspheres Microcapsules, where the entrapped substance is completely surrounded by a distinct capsule wall, and micromatrices, where the entrapped substance is dispersed throughout the microsphere matrix. [Pg.2328]

The form (soMd, liquid) the drag is given can affect the absorption rate. Drugs can be processed when they are manufactured to add other ingredients that will help or hinder absorption. [Pg.52]
