A Case Study Demonstrating the Importance of Glass Vial Selection for Parenteral Pharmaceutical Products.

There are many factors to consider when selecting a container closure system for parenteral drug products to maintain their quality, efficacy, and safety. One aspect to consider for products stored in glass vials is the glass type. Although the glass vials in which most parenteral products are stored are classified as Type I by the United States Pharmacopoeia, Chapter <660>, not all glass vials that meet the glass performance characteristics of Type I are equivalent. In the study presented here, Type I glass vials from three suppliers of three different Type I glass vials (standard, delamination control, and coated) were investigated to evaluate the impact that each Type I glass vial had on the stability of a drug product under development. To evaluate this impact, a three-phase study was conducted in which the compatibility between the drug product and each vial was assessed through the measurement of the critical quality attributes of the product, extractable and leachable inorganic elements were analyzed for each vial, and finally a stability study under accelerated conditions was conducted for the drug product in the most compatible vial based on the aforementioned experiments. Results from this study demonstrated that there are, in fact, significant differences in glass vials regardless of their classification as Type I. In the study conducted here, delamination control Type I glass vials were found to be superior to both Standard Type I and coated Type I vials for the drug product under investigation.

A Critical Review of Icosapent Ethyl in Cardiovascular Risk Reduction.

Icosapent ethyl (IPE) was the first fish oil product the US Food and Drug Administration (FDA) approved to reduce the risk of atherosclerotic cardiovascular disease (ASCVD) in adults. IPE is an esterified version of eicosapentaenoic acid (EPA) and acts as a prodrug in the body to exert its effects. IPE affects the body primarily through triglyceride (TG) reduction and was initially indicated for hypertriglyceridemia in addition to statin therapy or for patients with statin intolerances. Various studies have investigated this agent, and multiple subanalyses have been conducted since the FDA approval. These subanalyses have assessed factors such as sex, statin therapy, high-sensitivity C-reactive protein levels (hs-CRP), and various inflammatory biomarkers in groups of patients taking IPE. This article aims to provide a critical review of the clinical data available regarding cardiovascular benefits of IPE in patients with ASCVD and its value as a treatment option for patients with elevated TG levels.
