This document discusses the manufacturing techniques of parenteral products. It begins with an introduction to parenterals and their advantages and disadvantages. It then discusses the types of parenterals including large volume parenterals (LVPs) and small volume parenterals (SVPs), and their formulations. The document provides details on the manufacturing processes of LVPs using blow fill and seal technology and of SVPs such as ampules. It compares LVPs and SVPs and concludes that the parenteral route is effective for delivering drugs that cannot be taken orally or that are highly hydrophobic.
