Article on Parentral Formulations

Abstract

Parenteral preparations are single-dose or multiple-dose containers of sterile, pyrogen-free liquids or solid dosage forms containing one or more active agents. They are designed to be injected, infused, or implanted into the body for administration. The Greek words para, which means outside, and enteron, which means intestine, are the origin of the word parenteral. Excipients such solvents, suspending agents, buffering agents, blood isotonicity-increasing agents, stabilizers, or antimicrobial preservatives may be present in parenteral solutions. A minimal number of excipients should be added. Excipients shouldn't be utilized in a way that compromises the stability, bioavailability, safety, or effectiveness of the active ingredient(s), or that results in toxicity or excessive local irritability. The production procedure should adhere to good production Practice guidelines. Starting material quality, equipment design and upkeep, and manufacturing technique must all be such that they guarantee the stability of the active ingredient and a finished product that is sterile, free of pyrogens, and contains no particulates. An overview of the parenteral medication delivery system is provided in this paper. First, various delivery methods, parenteral formulations, their varieties, and containers used are mentioned. The general manufacturing process, parenteral drug evaluation assays, and preformulation and pharmaceutical aspects that affect parenteral administration are reviewed in the second section.
