Visible particulates in injectable products directly jeopardize patient safety, and it is a critical quality attributes of injectable products. In recent years, unqualified products and recall events related to injectable products caused by visible particulates occurred frequently. Therefore, it is necessary to conduct the risk assessment, production process control and product detection of visible particulates in injectable products. Referring to the U.S. FDA Inspection of Injectable Products for Visible Particulates Guidance for Industry (draft guidance) and relevant guidelines and manufacturing and controls (CMC) review experience, this article mainly introduces and discusses the ideas of visible particulate control in chemical injections from the aspects like concept of visible particulates, quality risk assessment, production process and sample inspection control, life cycle management, etc., hoping to provide reference for the control and evaluation of visible particulates in injections.
