The principles and uses of membrane filtration in the preparation of pharmaceutical solutions are discussed. The preparation of pharmaceutical solutions often requires their passage through a thin polymeric membrane containing many tiny pores. The purpose is to remove viable and nonviable particles in order to clarify or sterilize the solution. Particles may be retained by sieving, entrapment, or electrostatic attraction. The largest pore size that will yield a sterile filtrate is 0.2 microns… CONTINUE READING
